Resumo

Fourteen female dogs diagnosed with pyometra were studied at three separate times: at diagnosis (T0) and 24 h (T1) and 10-15 days (T2) after ovariohysterectomy (OH). The means of the markers, symmetric dimethylarginine (SDMA) (17.71 to 26.54 µg/dL) and the urinary gamma-glutamyl transferase to creatinine ratio (uGGT/uCr) (1.06 to 2.62 U/mg), varied, showing an increase with time. Further, the elevation of gamma-glutamyl transferase (uGGT) (56.61 to 128.12 U/L) and the urinary protein to creatinine ratio (RPC) (0.26 to 1.24) was evident at T0 and T1. A reduction in the means of RPC, uGGT, and uGGT/uCr was observed 10-15 days after OH. Despite the elevation of these markers, the concentration of creatinine (1.11 to 1.40 mg/dL), urea (40.07 to 67.16 mg/dL), and urinary specific gravity (1.027 to 1.028) only presented slight variation. In canine pyometra, complications secondary to acute renal injury may be present that may be mild and transient in most treated animals. As elevation in SDMA and RPC preceded changes in creatinine levels for the evaluation of glomerular filtration, tubular markers could assist in the early identification of renal damage in canine pyometra.(AU)


Catorze cadelas com diagnóstico de piometra foram estudadas em três tempos distintos, sendo no momento do diagnóstico (T0), 24 horas (T1) e 10 a 15 dias (T2) após a ovário-histerectomia (OH). O objetivo foi avaliar o uso de diferentes biomarcadores renais em cadelas com piometra e estimar suas precocidades diante do agravo. As médias em dimetilarginina simétrica (SDMA) (17,71 a 26,54µg/dL) e relação gama-glutamil transferase e creatinina urinária (uGGT/uCr) (1,06 a 2,62U/mg) variara, apresentando aumento em todos os momentos. Já a elevação do gama-glutamil transferase (uGGT) (56,61 a 128,12 U/L) e da razão proteína e creatinina urinárias (RPC) (0,26 a 1,24) foram evidenciadas nos dois primeiros tempos. Uma redução na média do RPC, uGGT e uGGT/uCr foi observada 10-15 dias após a implantação do tratamento (OH). Apesar da elevação desses marcadores, a concentração de creatinina (1,11 a 1,40mg/dL), ureia (40,07 a 67,16mg/dL) e densidade urinária (1,027 a 1,028) sofreram poucas variações. Em piometra canina, as complicações renais agudas secundárias podem estar presentes, ainda que leve e transitória nos animais tratados. Os marcadores tubulares foram considerados precoces na injúria renal aguda. Além disso, a SDMA e o RPC antecederam as alterações de creatinina em todos os tempos analisados.(AU)

Artificial light, as one of the environmental factors, plays a significant role in regulating the synthesis and secretion of hormones related to the coordination of parameters of life, growth, immunity, and reproductive functions of hens. The article aims to study the influence of monochrome light with different wavelengths on the biochemical parameters of hens` blood serum. Four groups of "Hy-Line W-36" crossbred hens were formed. Hens of the 1st group were kept using monochrome light with different wavelength lamps with a wavelength of ~ 460 nm, the 2nd group ~ 600 nm, the 3rd group ~ 630 nm, and the 4th group ~ 650 nm. It was found that the use of light with different wavelengths for keeping hens in cages of multilevel batteries affects hen' biochemical parameters, according to the research results. It was established that when using light with a wavelength of ~ 630 and ~ 650 nm, the indicators of clinical biochemistry of hens' blood serum were within the normal physiological values. Whereas, with the use of light with a wavelength of ~ 600 nm, an increase in the level of glucose, creatinine, total protein, total bilirubin, and phosphorus, a decrease in the ratio of calcium to phosphorus, in the activity of alkaline phosphatase, aspartate aminotransferase, and lactate dehydrogenase, were observed in the hens' blood serum. The use of light with a wavelength of ~ 460 nm was accompanied by a further increase in the level of glucose, creatinine, total protein, urea, total bilirubin, phosphorus, the activity of alkaline phosphatase, aspartate aminotransferase, lactate dehydrogenase, and gamma-glutamyltransferase, a decrease in the ratio of calcium and phosphorus.

The objective of this study was to evaluate the hematology and serum biochemistry of broilers fed diets supplemented with chondroitin and glucosamine sulfates. An experiment was laid out in a completely randomized design with a 3 × 3 factorial arrangement (three levels of chondroitin sulfate: 0, 0.05 and 0.10%; and three levels of glucosamine sulfate: 0, 0.15, and 0.30%), with each treatment involving six replicates of 30 birds. Hematology (red blood cells, hemoglobin, hematocrit, total plasma protein [TPP], thrombocytes, white blood cells, eosinophils, monocytes, heterophils, and lymphocytes) and serum biochemistry (totalinteraction between sulfates influenced (p < 0.05) total calcium by 21 days, ionic calcium by 21 and 42 days, and phosphorus, chlorides, and sodium by 42 days. Supplementation with chondroitin and glucosamine sulfates in the broilers' diet favored their immune system and mineral metabolism, increasing serum concentrations of calcium, phosphorus, and sodium. serum protein [TSP], albumin, globulins, aspartate aminotransferase [AST], gamma-glutamyltransferase [GGT], alkaline phosphatase [AP], total calcium, ionic calcium, phosphorus, sodium, potassium, and chlorides) variables were evaluated at 21 and 42 days. Data were subjected to analysis of variance. When the means differed significantly by the F-test, orthogonal analysis was performed to test the linear and quadratic effects of chondroitin and glucosamine sulfate levels. Glucosamine sulfate reduced the number of monocytes linearly, by 42 days (p = 0.0399). There was an interaction effect between the sulfates on total white blood cells (p = 0.0099) and lymphocytes (p = 0.0004) by 21 days. Chickens supplemented with 0.10% chondroitin sulfate showed a linear increase in white blood cells (p = 0.0287) and lymphocytes (p = 0.0144) with the addition of glucosamine sulfate. Chondroitin sulfate supplementation increased serum albumin linearly (p = 0.0099) and TSP quadratically (p = 0.0140), by 21 days. Glucosamine sulfate induced a quadratic response (p < 0.05) in albumin by 42 days, with the lowest value found with the inclusion of 0.06%. Glucosamine sulfate reduced chlorides linearly (p = 0.0237) by 21 days and increased calcium linearly (p = 0.0012) by 42 days. The interaction between sulfates influenced (p < 0.05) total calcium by 21 days, ionic calcium by 21 and 42 days, and phosphorus, chlorides, and sodium by 42 days. Supplementation with chondroitin and glucosamine sulfates in the broilers' diet favored their immune system and mineral metabolism, increasing serum concentrations of calcium, phosphorus, and sodium.(AU)


Objetivou-se avaliar a hematologia e a bioquímica sérica de frangos de corte suplementados com sulfatos de condroitina e de glucosamina na ração. Foi conduzido um experimento em delineamento inteiramente casualizado, em esquema fatorial 3 x 3 (três níveis de sulfato de condroitina: 0; 0,05 e 0,10%; e três níveis de sulfato de glucosamina: 0; 0,15 e 0,30%), cada tratamento com seis repetições de 30 aves. Foram avaliadas as variáveis de hematologia (hemácias, hemoglobina, hematócrito, proteínas plasmáticas totais [PPT], trombócitos, leucócitos, eosinófilos, monócitos, heterofilos e linfócitos) e bioquímica sérica (proteínas séricas totais [PST], albumina, globulinas, aspartato aminotransferase [AST], gama glutamiltransferase [GGT], fosfatase alcalina [FA], cálcio total, cálcio iônico, fósforo, sódio, potássio e cloretos) aos 21 e 42 dias. Os dados foram submetidos à análise de variância. Quando as médias diferiram significativamente pelo teste F, a análise ortogonal foi realizada para testar os efeitos lineares e quadráticos dos níveis dos sulfatos de condroitina e de glucosamina. Observou-se efeito linear decrescente (p = 0,0399) do sulfato de glucosamina na quantidade de monócitos aos 42 dias. Houve interação dos sulfatos para leucócitos totais (p = 0,0099) e linfócitos (p = 0,0004) aos 21 dias. Frangos suplementados com 0,10% de sulfato de condroitina mostraram um aumento linear dos leucócitos (p = 0,0287) e dos linfócitos (p = 0,0144) com a inclusão de sulfato de glucosamina. A suplementação com sulfato de condroitina aumentou linearmente (p = 0,0099) a albumina sérica e afetou de forma quadrática (p = 0,0140) as PST aos 21 dias. O sulfato de glucosamina demonstrou um efeito quadrático (p < 0,05) sobre a albumina aos 42 dias, o menor valor foi encontrado para a inclusão de 0,06%, respectivamente. O sulfato de glucosamina reduziu linearmente (p = 0,0237) os cloretos aos 21 dias e aumentou linearmente (p = 0,0012) o cálcio total aos 42 dias. Verificouse interação (p < 0,05) dos sulfatos para cálcio total aos 21 dias, cálcio iônico aos 21 e 42 dias e para fósforo, cloretos e sódio aos 42 dias. A suplementação com os sulfatos de condroitina e de glucosamina na ração de frangos de corte favoreceram o sistema imune e o metabolismo de minerais, com aumento nas concentrações séricas de cálcio, fósforo e sódio.(AU)

The aim of this study was to evaluate the influence of completely replacing soybean meal (SM) with castor cake detoxified (DCC) with two alkaline products on the nitrogen balance and hepatic and renal function in goat kids. Goatkids of two breeds, Saanen and Anglo Nubian, with an initial body weight of 16.2 ± 0.67 kg, and confined during the growth phase, were used. The treatments consisted of three diets: one based on SM and the other two based on castor cake detoxified with Ca(OH)2or NaOH. Twenty-four goats kids were distributed in a completelyrandomized design using a 3 x 2 factorial scheme (diet x breed) with four replicates per combination. The experimental period lasted for 270 days. Consumed nitrogen, fecal nitrogen, urinary nitrogen, retained nitrogen, and nitrogen balance were influenced(p < 0.05) by diets. There was significant effect of diets (p < 0.05) on creatinine, direct bilirubin, urea, alanine aminotransferase, aspartate aminotransferase and gamma-glutamyltransferase blood levels, however without any negative changes involving renal or hepatic dysfunction. Inclusion of castor cake in the diet of goats kids in confinement is an attractive option, considering that goats kids use does not cause hepatic and renal alterations, suggesting that SM can be completely replaced. NaOH DCC stands in the substitution of soybean meal, because in spite of decreasing the consumption of nitrogen provides the same retention of soybean meal.(AU)

Background: Hormonal and physiological changes during pregnancy period have significant effects on animals' metabolisms. The purpose of the present study is to evaluate the variations of aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) levels according to different gestation trimesters of the pregnant mares to assess changes of embryonic losses and abortions. Materials, Methods & Results: Blood samples from 49 thoroughbred mares were analyzed during this study. Age ratio of the mares is 5-18 years and their body condition score (BCS; score 1 to 9) varies between 5 and 6. A total of 28 mares had given birth to healthy foals at the end of a healthy gestation period (Group C), whereas 11 mares had embryonic losses (Group E) and 10 mares had late period abortions (Group A). Following the confirmation of pregnancy, one blood sample per gestation trimester were taken (14-16 days of pregnancy for 1st trimester; 180 days for 2nd trimester, 270 days for 3rd trimester). Early embryonic losses (loss of a 16-25 days embryo) were observed in 6 of 11 mares in Group E and the 5 of 11 mares had late period embryonic losses (loss of a 35-40 days embryo). In Group A, 6 mares had the abortion within 7th month and the remaining 4 mares had the abortion within the 8th month of pregnancy. Repeated Measures ANOVA, Kruskal-Wallis test and Mann-Whitney test were performed for statistical analysis, the mean AST level in Group C (n = 28) was higher during the 1st trimester in comparison to 2 following trimesters (respectively: P = 0.011 ; P = 0.01). Besides, no statistical difference was observed between 2nd and 3rd trimester regarding AST activation (P > 0.05). The mean GGT level in Group C was significantly decreased lower in the 3rd trimester compared to 1st and 2nd trimester (respectively: P = 0.007 ; P = 0.009). No statistical difference was observed between 2nd and 3rd trimester regarding GGT activation (P > 0.05). Among all groups (C, E, A) no significant difference was observed on AST levels (P > 0.05), nonetheless GGT levels had a significant rise (P = 0.039) in Group A in comparison to the 1st trimester levels of Group C. In Group A, there was a statistical decrease of AST during the 2nd trimester in comparison to the 1st trimester (P = 0.001), accompanied by a decrease of GGT activation during the 2nd trimester compared to the 1st trimester (P = 0.009). Discussion: The aminotransferases are catalisors that play an important role on the metabolism of amino acids and carbohydrates. Although serum AST levels were within the reference ranges during 3 trimesters in this study, serum AST levels were determined to be decreased in the 2nd and 3rd trimesters in healthy pregnant mares compared to the 1st trimester. It is thought that these results can be obtained due to the increase in metabolic needs during pregnancy. In this study, serum GGT levels remained within physiological limits with a tendency to decrease as the pregnancy advances, in accordance with previous study results. Serum GGT levels that are used as an indicator to liver damage may vary during the pregnancy as a result of increased metabolic load. It is thought that the increase of serum GGT levels in Group A might be related to the fetal (chromosome-related) issues that may result to pregnancy losses. As a result, it is considered that serum AST and GGT levels in mares might be valuable parameters that predict embryonic loss or abortus cases.

We describe here hematological and biochemical findings in a cow with metastatic cholangiocarcinoma. On physical examination, apathy with congested mucous membranes, tachycardia and enlarged abdomen; hypoperistalsis in rumen, abomasum and intestines. In hematological examination, icteric plasma with leukocytosis by neutrophilia with regenerative left shift and inversion of the proportion between lymphocytes and segmented neutrophils, and hypofibrinemia. In serum biochemistry: hyperproteinemia, hypoalbuminemia, hyperglobulinemia, low albumin/globulin ratio and high levels of aspartate aminotransferase, gamma-glutamyltransferase. The cow died and in necropsy was observed a severe and diffuse increase in volume predominantly on the hepatic right lobe and moderate increase of volume in mesenteric lymph nodes. Which was diagnosed microscopically as a cholangiocarcinoma, characterized by arrangements in irregular and coalescent ducts. In conclusion, cholangiocarcinoma may cause important hematological and biochemical changes in cattle.(AU)

ABSTRACT The objective of this study was to evaluate the biochemical parameters of goats submitted to castration or not and receiving supplementation with vitamin E or not. A total of 24 goats, uncastrated (12 experimental units) and castrated males (12 experimental units), with average body weight weighing 17.6 kg ± 2.67 kg, were distributed in a completely randomized design in a 2 x 2 factorial arrangement, with two animal conditions (castrated and uncastrated male) and vitamin E supplementation (with and without supplementation), with six replications. There was an effect of treatments (P 0.05) over time for all studied variables. There was an effect of vitamin supplementation (P 0.05) for phosphorus, iron, protein, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALP) and gamma-glutamyltransferase (GGT). Vitamin supplementation increased glucose, creatinine and GTT levels over time, and reduced levels of phosphorus, iron, protein, albumin, AST and ALP. We conclude that vitamin E influenced the biochemical parameters studied, but castration did not change the biochemical profile of goats, regardless of whether they were supplemented with vitamin E or not.


RESUMO Objetivou-se avaliar os parâmetros bioquímicos de caprinos submetidos ou não a castração e recebendo ou não suplementação com vitamina E. Um total de 24 caprinos, machos não castrados (12 unidades experimentais) e machos castrados (12 unidades experimentais), com peso corporal médio de 17,6 kg ± 2,67 kg, foram distribuídos em delineamento inteiramente casualizado em arranjo fatorial 2 x 2, sendo duas condições animais (macho castrado e não castrado) e suplementação com vitamina E (com e sem suplementação), com seis repetições. Houve efeito dos tratamentos (P 0,05) ao longo do tempo para todas as variáveis estudadas. Houve efeito da suplementação vitamínica (P 0,05) para fósforo, ferro, proteína, glicose, aspartato aminotransferase (AST), alanina aminotransferase (ALP) e gama-glutamiltransferase (GGT). A suplementação vitamínica elevou os níveis de glicose, creatinina e GTT ao longo do tempo, e reduziu os níveis de fósforo, ferro, proteína, albumina, AST e ALP. Concluímos que a vitamina E influenciou nos parâmetros bioquímicos estudados, porém a castração não alterou o perfil bioquímico de caprinos, independentemente de estarem suplementados ou não com a vitamina E.

Corticosteroid therapy has been used for ruminants to allow lung maturation and the birth of premature babies. However, when considering laboratory analyses of these animals, very little data is available regarding hematological and biochemical patterns, especially for premature goats, and the effects of corticotherapy on these parameters are unknown. In this context, the objective of this study was to evaluate the hematological and biochemical parameters during the first hours of life of premature kids from goats subjected to different dexamethasone protocols. For this, the goats were divided into four groups: group I, goats that received 20 mg of dexamethasone at 139 days of gestation; group II, 2 mg of dexamethasone from the 133rd to 136th day of gestation, 4 mg from the 137th to 139th, and 20 mg on the 140th; group III, 16 mg of dexamethasone from the 139th day, with repeated doses every 12 h until elective surgery; and group IV, goats that received 4, 8, 16, and 20 mg of dexamethasone at 137, 138, 139, and 140 days of gestation, respectively. Blood samples were obtained at birth (T0h) and after 1 (T1h), 12 (T12h), 24 (T24h), and 48 h (T48h) of life for hemogram and serum biochemistry assessment of urea, creatinine, total protein (PT), and gamma-glutamyltransferase (GGT). PT levels and GGT activity were lower at birth in all groups and rose after colostrum ingestion. The creatinine values for all the experimental groups did not differ between T0h and T1h; however, they decreased in the subsequent moments. Except for group I, urea concentrations were higher at T48h than at T1h. The red blood cell, hemoglobin, hematocrit, and mean corpuscular hemoglobin counts decreased over time. The total leukocyte count behaved differently in different experimental groups, and was influenced by the levels of dexamethasone, mainly due to the change in the counts of segmented neutrophils and lymphocytes. It was concluded that significant changes in the hematological and biochemical parameters occur in the first hours of life of premature kids, and that the treatment of goats with dexamethasone can affect these parameters in a dose-dependent manner.


A corticoterapia tem sido empregada em ruminantes com o objetivo de permitir a maturação pulmonar e o nascimento de filhotes prematuros. Entretanto, ao se considerar análises laboratoriais desses animais, pouquíssimos dados estão disponíveis quanto aos padrões hematológicos e bioquímicos, especialmente em caprinos prematuros, e tampouco se sabe sobre os efeitos da corticoterapia sobre parâmetros hematológicos e bioquímicos nesses animais. Nesse contexto, objetivou-se avaliar os parâmetros hematológicos e bioquímicos das primeiras horas de vida de cabritos prematuros provenientes de cabras que utilizaram diferentes protocolos de dexametasona. Para tal, as cabras foram divididas em três grupos: grupo I, cabras que receberam 20 mg de dexametasona aos 139 dias de gestação; grupo II, 2 mg de dexametasona do 133° ao 136° dia de gestação, 4 mg do 137° ao 139° e 20 mg no 140° dia; grupo III, 16 mg de dexametasona a partir do 139° dia, com doses repetidas a cada 12 horas até a cirurgia eletiva; e grupo IV, cabras que receberam 4, 8, 16 e 20 mg de dexametasona no 137°, 138°, 139° e 140° dias de gestação, respectivamente. As amostras sanguíneas dos cabritos foram obtidas ao nascimento (T0h), 1 (T1h), 12 (T12h), 24 (T24h) e 48 horas (T48h) de vida para avaliação do hemograma e bioquímica sérica de ureia, creatinina, proteína total (PT) e gamaglutamiltransferase (GGT). Os teores de PT e atividade de GGT foram menores ao nascimento em todos os grupos, elevando-se após ingestão do colostro. Os valores de creatinina em todos os grupos experimentais não diferiram entre T0h e T1H, entretanto, diminuíram nos momentos subsequentes. Com exceção do grupo I, as concentrações de ureia foram maiores no T48h em comparação com o T1h. Os valores de hemácias, hemoglobina, hematócrito e volume corpuscular médio diminuíram ao longo do tempo, enquanto a concentração de hemoglobina corpuscular média aumentou ao longo do tempo. A contagem leucocitária total se comportou de maneira distinta nos diferentes grupos experimentais, demonstrado ser influenciada pelos teores de dexametasona principalmente em decorrência da alteração nas contagens de neutrófilos segmentados e linfócitos. Conclui-se que alterações significativas dos parâmetros hematológicos e bioquímicos ocorrem nas primeiras horas de vida de cabritos prematuros e o tratamento de cabras com dexametasona também pode afetar tais parâmetros de forma dependente da dose.

As mycotoxins are consistent contaminants in the dairy cow diet, the use of adsorbents is recommended, although there are no ideal adsorbents. Although there are studies on this subject, few have focused on chronic natural intoxications. Here, we evaluated the effect of bentonite adsorbents associated with liver antioxidants on the health and milk production of dairy cows fed a diet containing naturally-produced fumonisin, zearalenone, and deoxynivalenol. Eighteen dairy cows (bodyweight 550 ±50 kg, 5 ± 2 years old, and 30 ± 1,25 kg/day milk production) in the middle of lactation were divided into groups: treatment (TG, n = 9, 22 g/day of supplement added to diet) and control (CG, n = 9, without supplement). A physical examination was performed, weekly over 56 days and blood was collected for liver and immune assessments. Milk was harvested to evaluate milk production and content (fat protein, somatic cell count, and lactose). The additive promoted beneficial effects on the liver from the 24th day due to a decrease in the enzymatic activities of gamma-glutamyltransferase and lactate dehydrogenase and increased serum protein and albumin levels. There were improvements in health, evidenced as fewer clinical manifestations of the disease, greater leukocyte oxidative metabolism capacity, and a lower neutrophil lymphocytes ratio. The treatment also promoted a 19% increase in milk volume. It was concluded that the additive promoted health benefits and milk production in dairy cows.(AU)


Como as micotoxinas são contaminantes constantes na dieta de vacas leiteiras, o uso de adsorventes é recomendado, embora não existam adsorventes ideiais. Ainda que existam estudos sobre o assunto, poucos são direcionados às intoxicações naturais crônicas. Nosso experimento avaliou o efeito do adsorvente bentonita associado a antioxidantes hepáticos sobre a saúde e produção de leite de vacas leiteiras alimentadas com dieta contendo fumonisina, zearalenona e desoxinivalenol produzidos naturalmente. Dezoito vacas lei-teiras (peso corporal 550 ±50 kg, 5±2 anos de idade, e 30 ± 1,25 kg/dia de produção de leite) no meio da lactação, foram divididas em grupos: Tratamento (GT, n=9, 22g/dia do suplemento adicionado à dieta) e controle (GC, n =9, sem suplemento). Em intervalos semanais, durante 56 dias, foi realizado exame físico, coleta de sangue para avaliação hepática e imunológica. O leite foi colhido para avaliar a produção e análises de leite para (proteína, gordura, contagem de células somáticas e lactose). O aditivo promoveu efeitos bené-ficos no fígado à partir do 24º dia devido à diminuição das atividades enzimáticas da gama-glutamiltransferase e lactato desidrogenase e aumento dos níveis séricos de proteína e albumina. Houve melhora na saúde, evidenciada por menor número de manifestações clínicas de doença, maior capacidade de metabolismo oxidativo dos leucócitos e menor razão neutrófilos/linfócitos. O tratamento também promo-veu aumento de 19% no volume de leite. Concluiu-se que o aditivo promoveu benefícios à saúde e à produção de leite em vacas leiteiras.(AU)

Resumo

This study aimed to evaluate the effects of animal age and sex on serum concentrations of proteins, metabolites, minerals, and enzymes in Bonsmara cattle up to two years of age. Blood samples were collected from 179 animals (92 males and 87 females), aged between 15 days and 24 months. The animals were divided into four age groups: G1: 15 days ┤2 months, G2: 2 ┤6 months, G3: 6 ┤ 12 months, and G4: 12 ┤24 months of age. The samples were processed in an automatic multichannel analyzer using Labtest Diagnóstica™ kits. Animal age had a significant influence on most of the serum biochemical constituents except for magnesium (Mg) and the Ca+:iP ratio. As age increased, G3 showed the highest concentrations of total proteins (TP), globulins (Glob), urea, and cholesterol (Chol); while G4 had a gradual increase and higher values of creatinine (Crea), aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Conversely, albumin:globulin (A:G) ratio, calcium (Ca+), inorganic phosphorus (iP), alkaline phosphatase (ALP), and gamma-glutamyltransferase (GGT) decreased from G1 to G4. Moreover, animal sex influenced serum values of albumin (ALB), Glob, A:G ratio, Crea, urea, triglycerides (TRI), Ca+, iP, Ca+:iP ratio and Mg. In conclusion, the factors of age group and sex significantly influenced the concentrations of serum biochemical constituents in Bonsmara cattle in the growth phase.


Objetivou-se avaliar a infuência da idade e sexo nas concentrações séricas de proteínas, metabólitos, minerais e enzimas em bovinos da raça Bonsmara com até dois anos de idade. Foram colhidas amostras de sangue de 179 animais (92 machos e 87 fêmeas), de 15 dias a 24 meses de idade, distribuídos em quatro grupos etários: G1: 15 dias ┤2 meses, G2: 2 ┤6 meses, G3: 6 ┤12 meses e G4: 12 ┤24 meses de idade. As amostras foram processadas em analisador automático multicanal, utilizando kits da Labtest Diagnóstica®. A variável idade dos animais influenciou significativamente nos valores da maioria dos constituintes bioquímicos séricos avaliados, exceto no magnésio (Mg) e na relação Ca+:Pi. O aumento da idade culminou com a maior concentração das proteínas totais (PT), globulinas (Glob), ureia e colesterol (COL) no G3; aumento gradual e maior valor de creatinina (Crea), aspartato aminotransferase (AST) e alanina aminotransferase (ALT) no G4. Em contrapartida, houve diminuição da relação albumina:globulina (A:G), cálcio (Ca+), fósforo inorgânico (Pi), fosfatase alcalina (FAL) e gama glutamiltransferase (GGT) do G1 ao G4. O fator sexo influenciou nos valores séricos da albumina (ALB), Glob, relação A:G, Crea, ureia, triglicérides (TRI), Ca+, Pi, relação Ca+:Pi e Mg. Conclui-se que o fator idade e sexo influenciaram significativamente nos valores dos constituintes bioquímicos séricos analisados de bovinos da raça Bonsmara em fase de crescimento.

This study aimed to evaluate the renal function of six bitches of various breeds and ages, with open pyometra, attended in the Small Animal Medical Clinic sector of the Veterinary Hospital from Federal University of Campina Grande, through the measurement of laboratory tests: urea and creatinine serum, dosage of the urinary Protein-Creatinine Ratio (PCR), urinary gamma-glutamyltransferase (GGT) and determination of the renal resistivity index (RI). The levels of urea and creatinine were elevated in 16.6% (1/6) of the female dogs; the urinary protein-creatinine ratio was increased in 66.6% (4/6), while the urinary gamma-glutamyltransferase value was elevated in 50% (3/6). The renal resistivity index was increased in the right and left kidneys by 66.6% (4/6) of bitches, with no statistical difference between them. It was concluded that the renal resistivity index was a practical and effective method to assist in the diagnosis of acute kidney injury, along with other early markers, such as PCR and urinary GGT.

O conhecimento dos intervalos de referência para parâmetros clínicos e bioquímicos nas diferentes espécies e a influência da raça e da idade sobre eles é uma ferramenta fundamental para o Médico Veterinário. Neste sentido, o objetivo deste estudo foi descrever os parâmetros clínicos e bioquímicos de jumentos neonatos da raça Pêga. Desta forma, foram avaliados 10 jumentos neonatos ao nascimento (M0), 7 dias de vida (M1), 14 dias (M2), 21 dias (M3), 28 dias (M4) e 35 dias (M5), além da determinação das concentrações de aspartato aminotransferase (AST), creatina quinase (CK), gama glutamiltransferase (GGT) e albumina (ALB). Em relação ao exame clínico, foram observadas diferenças estatísticas nos valores da frequência respiratória (FR, mpm) e temperatura retal (ToC), que sofreram alterações nos neonatos estudados. Dentre as análises bioquímicas, os valores de AST apresentaram significância estatística, com valores superiores aos descritos pela literatura consultada. Embora exista uma grande variação interindividual para alguns parâmetros, este estudo demonstrou que as referências de intervalo devem ser dirigidas não apenas as espécies diferentes, mas também a raças específicas e ao período neonatal, sendo este o primeiro estudo que descreve as características clínicas e bioquímicas de neonatos da raça Pêga.


Knowing the reference ranges for clinical and biochemical parameters in different species and the influence of race and age on them is a fundamental tool for the veterinarian. In this sense, the aim of this study was to describe the clinical and biochemical parameters of newborn Pegasus donkeys. Thus, 10 newborn donkeys at birth (M0), 7 days of life (M1), 14 days (M2), 21 days (M3), 28 days (M4) and 35 days (M5) were evaluated, in addition to the determination of concentrations of aspartate aminotransferase (AST), creatine kinase (CK), gamma glutamyltransferase (GGT) and albumin (ALB). Regarding the clinical examination, statistical differences were observed in the values of respiratory rate (RR, mpm) and rectal temperature (ToC), which changed in the studied neonates. Among the biochemical analyses, the AST values showed statistical significance, with values higher than those described in the consulted literature. Although there is great inter-individual variation for some parameters, this study demonstrated that interval references should be directed not only to different species, but also to specific races and the neonatal period, this being the first study to describe the clinical and biochemical characteristics of newborns of the Pega race.

Background: Otitis is a frequent condition in dogs, with a multifactorial etiology covering primary causes, predisposing and perpetuating factors. It is characterized by an inflammatory process of structures that make up the auditory system, with prevalence data ranging from 15 to 20%, which can occur in any age group and without sex predisposition. According to the location, it can be classified as uni or bilateral, affecting the outer, middle and / or inner ear, the latter two being associated with neurological changes such as vestibulopathy, facial nerve paresis and Horner's syndrome. The morbidity and mortality of otitis media and internal may increase with delay in diagnosis, resulting in delay in the correct treatment, and the extension to brainstem is described in felines and considered rare in dogs. The present study aims to report an atypical case of otitis media and internal, with extension to the brain parenchyma in a brachycephalic dog. Case: A 3-year-old bitch French Bulldog was seen, weighing 12 kg, with a history of vomiting, apathy, nystagmus, ataxia and acute evolution hemiparesis. As a result of adoption, it was not known about the animal's morbid past. On special physical and clinical examination, depressed mental status, changes in postural reactions, nostril stenosis with unilateral mucopurulent nasal discharge, corneal ulcer, palpebral and labial ptosis, absence of eyelid reflex and spontaneous strabismus were observed, all of these findings observed on the left side of the face. No signs of otitis external to otoscopy were found. The clinical signs found characterize left facial nerve paresis and peripheral and central vestibulopathy. Otitis media / internal and meningoencephalitis were suspected. Hemogram, serum biochemistry (glucose, urea, creatinine, alanine aminotransferase, total proteins, albumin, globulin, alkaline phosphatase, gamma glutamyltransferase, phosphorus, total bilirubin, cholesterol and total calcium), urinalysis, rapid tests for erlichiosis, anaplasms , borreliosis, heartworm, distemper and leishmaniasis, CSF analysis, neurological panel performed by PCR (Polymerase Chain Reaction) that tested the animal for Bartonellosis, Lyme Disease (Borrelia burgdorferi), Blastomyces dermatitidis, Cryptococcus sp., Virus West Nile, Distemper, Toxoplasmosis, Neosporose and Coccidioides sp. using conjunctival swab, whole blood, urine and CSF samples. The samples were negative for all of these tests. As an image exam, brain magnetic resonance was performed. In the latter, otitis media and left internal was observed with extension of the lesion to the brain parenchyma. CSF analysis showed cytological changes compatible with a non-suppurative inflammatory process, mild pleocytosis with predominantly mononuclear leukocyte infiltrate. As a form of treatment, antibiotic therapy and total ablation of the auditory canal with lateral bulectomy were performed, showing good results with reduced clinical symptoms. Discussion: It is concluded that although the diagnosis of otitis media and internal with extension to brainstem is more common in cats, it should be included as a differential for central vestibular disorders in dogs, and that the diagnosis together with early and effective treatment are important, since that the evolution of the infection to the central nervous system represents a risk to the patient.

Resumo

The aim of this study was to evaluate the metabolic, inflammatory, and hepatic aspects, as well as the milk yield in heifers submitted to protocol for induction of lactation compared to primiparous cows. Sixty Holstein heifers were selected and enrolled into two groups: Control (n= 30), pregnant heifers and Induction heifers (n= 30), non-pregnant femeales, submitted to a lactation induction protocol. Blood samples were collected at: pre-lactation period (weeks -3, -2 and -1) and post-lactation period (weeks 1, 2 and 3), aiming to evaluate glucose, non-esterified fatty acids, paraoxonase-1, albumin, ALT, GGT and cortisol. The protocol efficiently induced lactation in all the heifers, which produced 74.54% of the total production of milk from primiparous cows. In the pre-lactation period, induced animals presented higher concentrations of non-esterified fatty acids than the Control heifers, and the opposite was observed in the post lactation period. In both moments albumin and ALT were lower in the Induction group, and paraoxonase-1 activity and GGT concentrations were higher, compared to the Control. Thus, lactation induction protocol is efficient to initiate milk production in dairy heifers with no considerable changes in energetic, metabolic and hepatic profile when compared to heifers in physiological lactation.(AU)


O objetivo deste estudo foi avaliar os perfis metabólico, inflamatório, hepático e a produção de leite de novilhas induzidas à lactação comparadas a primíparas. Sessenta novilhas da raça Holandês foram selecionadas e alocadas em grupos: controle (n=30), novilhas prenhas, e indução (n=30), novilhas vazias submetidas a um protocolo de indução de lactação. As amostras de sangue foram coletadas nas semanas -3, -2 e -1 (pré-lactação) e nas semanas 1, 2 e 3 (pós-início de lactação) para avaliação de glicose, ácidos graxos não esterificados, paraoxonase-1, albumina, ALT, GGT e cortisol. O protocolo induziu eficientemente a lactação em todas as novilhas, que produziram 74,54% da produção total de leite do controle. No período pré-lactação, o grupo indução apresentou maiores concentrações de ácidos graxos não esterificados que o controle, e o oposto foi observado pós-lactação. Em ambos os momentos, albumina e ALT foram menores no grupo indução, e a atividade da paraoxonase-1 e as concentrações de GGT foram maiores, em comparação ao controle. Assim, o protocolo de indução de lactação foi eficiente para iniciar a produção de leite em novilhas induzidas, além de terem sido observadas alterações nos perfis energético, metabólico e hepático em comparação a novilhas em lactação fisiológica.(AU)
