The present research aims to evaluate the inclusion of an emulsifying additive based on mono- and diglycerides of fatty acids in diets with different lipid sources, studying its effects on duodenum histology, biometry of the digestive and reproductive tract, and blood biochemical profile of Japanese quails. The study was carried out in the experimental aviary of the Federal University of Grande Dourados, Mato Grosso do Sul, Brazil. The experimental design was completely randomized, with diets in a 3x2 factorial design with three different lipid sources (soybean oil, poultry fat, and beef tallow), either supplemented or not with an emulsifier. The birds that received a diet composed of poultry fat and an emulsifying additive had a larger gizzard. Animals that received a diet containing an emulsifier, regardless of the lipid source, had greater heart weight. The duodenum of animals that received bovine tallow in their diet showed a greater height and villus:crypt ratio. Biochemical parameters were not affected by either the lipid source or the inclusion of emulsifier in quail diets. The biochemical blood profile of birds in treatments did not show significant changes among all diets used. The use of soybean oil, bovine tallow, and poultry fat with or without the inclusion of an emulsifier does not show changes in the health and development of the quails' organs, which also indicates that the health of Japanese quails in the laying phase is kept in good standards.(AU)

Produce and compare soft cheese with potential benefits of human health from Egyptian buffalo's and cow's milk was studied. Eight Egyptian lactating buffalos and cows were fed a total mixed ration supplemented with either 0% oil (CD), 2% flaxseed oil (DFO), 2% soybean oil (DSO), or 2% of their mixture (1:1, DFSO) according to a double 4 x 4 Latin Square design. Milk yield was similar between buffalo's diets but was higher in cows fed a DFO, DSO or DFSO resulting in 11.15, 8.21% or 8.97% increases compared with the control diet, respectively. Milk composition was not significantly affected in both buffalos and cows fed diets. The DFO, DSO or DFSO displayed decreased short-chain fatty acids, especially DSO and DFSO (3.73 and 3.33%, respectively) when compared to CD for buffalo milk (6.32%). The DSO and DFSO were more effective for increasing unsaturated fatty acids followed by the DFSO in buffalo's milk fat (42.31 and 41.90 %), whereas DFO and DFSO were more effective in cow's milk fat (39.67 and 39.84%), respectively. DFO, DSO or DFSO had no significant effect on the yield, composition and sensory properties of resultant soft cheese compared to the CD for both lactating cows and buffalos. During storage, a diet rich in unsaturated fatty acids enhances protein proteolysis and antioxidant activity of soft cheese during storage compared to the CD especially for soft cheese produced from buffalo's milk.(AU)

Este trabalho teve como objetivo avaliar o efeito da substituição da farinha e do óleo de peixe pelo concentrado proteico de soja e óleo de soja, na sobrevivência, no crescimento e na composição corporal dos camarões (Litopenaeus vannamei) produzidos em sistema de bioflocos (BFT). Foram formuladas cinco dietas, isoproteicas e isoenergéticas, com diferentes níveis de substituição da farinha e do óleo de peixe por concentrado proteico de soja e óleo de soja, sendo os tratamentos designados como: 0% (sem substituição), 25%, 50%, 75% e 100%. As rações foram elaboradas para conter aproximadamente 35% de proteína e 8% de lipídios. O experimento foi conduzido durante 49 dias, com juvenis com peso inicial de 2,93±0,83g, em sistema de bioflocos (BFT). Não foram encontradas diferenças significativas entre os tratamentos até 75% de substituição para as variáveis de ganho de peso, conversão alimentar e sobrevivência. O tratamento de 100% de substituição apresentou menor taxa de crescimento específico. O presente resultado sugere que, nas dietas para camarões criados em sistema bioflocos, a farinha e o óleo de peixe possam ser substituídos em até 75% por concentrado proteico de soja e óleo de soja, sem prejudicar o desenvolvimento dos animais.(AU)


The objective of this work was to evaluate the effect of the substitution of fishmeal and fish oil with soy protein concentrate and soybean oil on survival, growth and body composition of shrimp (Litopenaeus vannamei) produced in biofloc system (BFT). Five diets were formulated to be isoproteic and isoenergetic with different levels of substitution of fishmeal and fish oil with soy protein concentrate and soybean oil. The treatments were named as: 0% (without substitution), 25%, 50%, 75% and 100%. The diets were formulated to contain approximately 35% protein and 8% lipids. The experiment was conducted for 49 days, with juveniles with initial weight of (2.93±0.83g) in a biofloc system (BFT). No significant differences were found between treatments up to 75% of substitution for the variables of weight gain, feed conversion ratio, and survival. The 100% substitution treatment showed a lower specific growth rate. The present study suggests fish meal and fish oil can be substituted in up to 75% for soy protein concentrate and soybean oil, without harming the development of the shrimps when reared in biofloc system.(AU)

ABSTRACT: The objective of this paper is to report the epidemiological, clinical, and pathological aspects of a case of rumenitis due to the ingestion of soybean oil in a bovine. The ox had access to barrels that stored soybean oil and ingested an indeterminate amount of the product. After consuming it, the animal presented hiporexia; liquid, brownish, and greasy feces; severe dehydration (12%); apathy; sternal recumbency; and death with a clinical evolution of 4 days. At necropsy, the rumen was filled with voluminous food and moderate amount of white-gray liquid with a greasy appearance. Upon microscopic examination, hydropic degeneration of the epithelium and areas of mucosal necrosis were observed in the rumen and reticulum. From these findings, we concluded that the bovine developed a state of acidosis and acute rumenitis due to excessive intake of lipids.


RESUMO: O objetivo deste trabalho é relatar os aspectos epidemiológicos, clínicos e patológicos de um caso de ruminite por ingestão de óleo de soja em um bovino. O animal teve acesso acidental a tonéis que armazenavam óleo de soja e ingeriu uma quantidade indeterminada do produto. Após o consumo, o bovino apresentou hiporexia, fezes líquidas, acastanhadas e de aspecto gorduroso, desidratação severa (12%), apatia, decúbito esternal e morte, com evolução clínica de quatro dias. Na necropsia o rúmen estava repleto por alimentos volumosos e moderada quantidade de líquido branco-acinzentado e de aspecto gorduroso. Microscopicamente, no rúmen e retículo havia degeneração hidrópica do epitélio e áreas de necrose da mucosa. A partir destes achados, concluímos que o bovino desenvolveu um quadro de acidose e ruminite aguda por consumo excessivo de lipídeos.

Exploring new feeding strategies are a necessary aspect for improving the reproductive performance in rabbits. Twenty healthy rabbit bucks with a mean live body weight of 1.01 kg (SD = 0.12)and age of 6 months old were used for a period of 17weeks to examine the influence of feeding soybean and sunflower oils on their reproductive performance. Rabbits were randomly assigned into 4 groups (5bucks/group), where bucks in the 1st group, served as a control, were fed for 14 weeks on a standard ration without any oil supplementation, while bucks in the 2nd, 3rd, and 4th groups received -on the basis of the inclusion rate- a ration supplemented with 3% soybean oil, 3% sunflower oil, and 1.5% soybean oil plus 1.5%sunflower oil, respectively. Climatic, bio-physiological, blood and seminal measurements were all been determined. The obtained results suggested that offering rations supplemented with soybean and/or sun flower oils at the level of 3% of DM to rabbit bucks had no impacts on their health status, based on the findings that feed conversion ratio, blood hematology as well as liver and kidney functions were all not altered; thereby, indicating that the refined vegetable oils can be safely.[...].

A adição de óleos na dieta de frangos de corte proporciona muitas vantagens, visto que, dependendo do perfil de ácidos graxos, pode melhorar o desempenho e atuar como estimulante do sistema imune. Assim, este estudo teve como objetivo avaliar as características produtivas, o rendimento de carcaça, os cortes e a resposta imune humoral de frangos de corte alimentados com diferentes fontes de óleos e vitamina E. Foram utilizados 312 pintainhos de corte machos da linhagem Cobb com um dia de idade, distribuídos em delineamento inteiramente ao acaso, com oito repetições compostas de 13 aves por parcela experimental. Os tratamentos experimentais consistiram em óleo de soja, óleo de canola e óleo de canola mais adição de vitamina E. As variáveis analisadas foram ganho de peso, consumo de ração, conversão alimentar, rendimento de carcaça, cortes comerciais e resposta imune humoral. Os resultados obtidos mostram que houve diferença significativa no desempenho somente na fase pré-inicial, quando as aves que receberam o tratamento com óleo de canola e vitamina E apresentaram piores ganhos de peso. Não foram observadas diferenças significativas para as outras variáveis analisadas. Conclui-se que a utilização de diferentes fontes lipídicas associadas ou não à vitamina E não afeta as características produtivas de carcaça, cortes e resposta imune humoral em frangos de corte em relação ao uso de óleo de soja.(AU)


Oil inclusion in poultry diets provides many advantages and according to the fatty acid profile it is possible to achieve performance improvement as well as immune system stimulation. Thus, the study aimed to evaluate productive performance, carcass and cuts yields and also the humoral immune response of broilers consuming diets formulated with different oil sources and vitamin E. A total of 312 one-day old male Cobb was distributed, in a completely randomized design, in three treatments with eight replications of 13 birds. The experimental treatments were the diets that had different oil source as follows: soybean oil, canola oil and canola oils with vitamin E. The analyzed parameters were weight gain, feed intake, feed conversion ratio, carcass and cut yields and humoral immune response. For the treatment with canola oil and vitamin E a reduction on weight gain during the pre-starter stage was observed. For the other evaluated parameters, no significant differences were observed. In conclusion, the use of canola oil or canola oil with added vitamin E does not affect the productive performance, carcass and cut yields and humoral immune response in broiler chicken in relation soybean oil use.(AU)

The search for new biocatalysts has aroused great interest due to the variety of micro-organisms and their role as enzyme producers. Native lipases from Aspergillus niger and Rhizopus javanicus were used to enrich the n-3 long-chain polyunsaturated fatty acids content in the triacylglycerols of soybean oil by acidolysis with free fatty acids from sardine oil in solvent-free media. For the immobilization process, the best lipase/support ratios were 1:3 (w/w) for Aspergillus niger lipase and 1:5 (w/w) for Rhizopus javanicus lipase using Amberlite MB-1. Both lipases maintained constant activity for 6 months at 4 °C. Reaction time, sardine-free fatty acids:soybean oil mole ratio and initial water content of the lipase were investigated to determine their effects on n-3 long-chain polyunsaturated fatty acids incorporation into soybean oil. Structured triacylglycerols with 11.7 and 7.2% of eicosapentaenoic acid + docosahexaenoic acid were obtained using Aspergillus niger lipase and Rhizopus javanicus lipase, decreasing the n-6/n-3 fatty acids ratio of soybean oil (11:1 to 3.5:1 and 4.7:1, respectively). The best reaction conditions were: initial water content of lipase of 0.86% (w/w), sardine-free faty acids:soybean oil mole ratio of 3:1 and reaction time of 36 h, at 40 °C. The significant factors for the acidolysis reaction were the sardine-free fatty acids:soybean oil mole ratio and reaction time. The characterization of structured triacylglycerols was obtained using easy ambient sonic-spray ionization mass spectrometry. The enzymatic reaction led to the formation of many structured triacylglycerols containing eicosapentaenoic acid, docosahexaenoic acid or both polyunsaturated fatty acids.(AU)

The objective of this study was to evaluate the influence of the supplementation of vegetable oils rich in polyunsaturated fatty acids to the diet of Leghorn layers on yolk color and on yolk lipid oxidation of eggs stored at room temperature for 10 days. Sixty eggs laid by commercial white layers (Lohmann LSL) fed diets supplemented with different vegetable oils were used. Hens were fed one of the following treatment diets: conventional diet with no oil inclusion (T1); T1 diet with 2.5% linseed oil inclusion (T2); T1 diet with 2.5% canola oil (T3); T1 diet with 2.5% soybean oil (T4); T1 with 5.0% linseed oil (T5); T1 diet with 5.0% canola oil (T6); T1 diet with 5.0% soybean oil (T7); T1 diet with 2.5% linseed oil + 2.5% soybean oil (T8); T1 diet with 2.5% canola oil + 2.5% soybean oil (T9); and T1 diet with 2.5% linseed oil + 2.5% canola oil (T10). Eggs were evaluated as to yolk lipid peroxidation (TBARS values) and yolk color, as determined by colorimetry and subjective sensorial analysis. Data were submitted to analysis of variance and means were compared by the test of Tukey at 5% significance level. It was concluded that the inclusion of vegetable oils in commercial white layer diets does not significantly change egg yolk pigmentation, as colorimetrically evaluated. However, when subjectively assessed, the yolks of the eggs laid by hens fed diets supplemented with vegetable oils tend to be paler. The yolks of the eggs laid by layers fed diets containing sources of polyunsaturated fatty acids presented high lipid oxidation, particularly when compared with those derived from layers fed the diet with no oil supplementation.

O objetivo do trabalho foi avaliar o desempenho de leitões alimentados com duas fontes de óleos (soja e palma) em associação com maltodextrina e do blend de óleo de palma microencapsulado com maltodextrina, bem como os coeficientes de digestibilidade aparente dessas dietas. Utilizaram-se 162 leitões desmamados aos 21 dias, com peso médio inicial de 5,42 ± 0,55 kg, os quais foram distribuídos em delineamento de blocos ao acaso em três tratamentos e dezoito repetições compostas de três animais. Os tratamentos avaliados foram T1: rações com óleo de soja [3,03% nas dietas pré-iniciais (I) e iniciais (II)] e maltodextrina (10,00% na I e 5,93% na II); T2: rações com óleo de palma (3,03% na I e II) e maltodextrina (10,00% na I e 5,93% na II); T3: rações com óleo de palma microencapsulado pela maltodextrina na forma de blend (10,00% na I e II) e maltodextrina adicional ao blend (4,07% na I), para que a percentagem de maltodextrina permanecesse idêntica nas rações dos três tratamentos. Os dados de desempenho e digestibilidade foram submetidos à análise de variância, respectivamente, pelo procedimento MIXED e GLM do pacote estatístico SAS, sendo as médias comparadas pelo teste de Tukey (P0,05) para o CDR, GDP e CA dos leitões submetidos aos diferentes tratamentos. O CDA da MS foi 4,25% menor (P<0,05) para a dieta com óleo de palma microencapsulado pela maltodextrina em relação à dieta com óleo de soja...


The objective of this study was to evaluate the performance of piglets fed two sources of oil (soybean and palm oil) combined with maltodextrin and a blend of palm oil microencapsulated with maltodextrin, as well as the apparent digestibility coefficients of these diets. A total of 162 piglets weaned at 21 days, with a mean initial weight of 5.42 ± 0.55 kg, were allocated in a randomized block design consisting of three treatments and 18 replicates of three animals each. The following treatments were evaluated: T1: diet containing soybean oil [3.03% in the pre-initial (I) and initial (II) diets] and maltodextrin (10.0% in I and 5.93% in II); T2: diet containing palm oil (3.03% in I and II) and maltodextrin (10.0% in I and 5.93% in II); T3: diet containing a blend of palm oil microencapsulated with maltodextrin (10.0% in I and II) and maltodextrin added to the blend (4.07% in I) so that the percentage of maltodextrin would be identical in the diets of the three treatments. The performance and digestibility data were submitted to analysis of variance using the MIXED and GLM procedures, respectively, of the SAS package and means were compared by the Tukey test (P0.05) in DFI, ADG or FC were observed between piglets submitted to the different treatments. The ADC of dry matter was 4.25% lower (P<0.05) for the diet containing palm oil microencapsulated with maltodextrin compared to the soybean oil diet. The ADC of ether extract was 54% higher (P<0.05) in the soybean oil diet compared to the palm oil diet, which negatively affected the ether extract digestibility coefficient...

Resumo

This study evaluated the effect of using lipid sources of plant and animal origin in diets for Japanese quail (Coturnix coturnix japonica) on production performance and internal egg quality. Japanese quails (n = 160) were distributed in a completely randomized design with four treatments and eight replications of five birds each. Lipid sources evaluated were: soybean oil, from poultry slaughterhouse, fish waste and grape seed. The characteristics of performance and internal egg quality were measured every 21 days for a total period of 84 days. Data were subjected to analysis of variance and the means were compared by Tukeys test. There was no effect of treatments on the production performance of birds, except for feed intake, which was higher for birds fed grape seed oil in the diet. Lipid sources evaluated had no influence on the internal egg quality. It can be concluded that the lipid sources evaluated here in can be used as alternative energy in feed for laying quails, without affecting the performance and internal egg quality.


O objetivo deste trabalho foi avaliar a utilização de fontes lipídicas de origem animal e vegetal nas rações para codornas japonesas (Coturnix coturnix japonica), em relação ao desempenho zootécnico e à qualidade interna do ovo. Foram utilizadas 160 codornas japonesas, distribuídas em delineamento inteiramente casualizado, com quatro tratamentos e oito repetições por tratamento, com cinco aves por repetição. As fontes lipídicas avaliadas foram: óleo de soja, de abatedouro avícola, de resíduo de peixe e de semente de uva. As características de desempenho e qualidade interna dos ovos foram mensurados a cada 21 dias, em um período total de 84 dias. Os dados obtidos foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey. Não houve efeito dos tratamentos sobre o desempenho produtivo das aves, exceto para o consumo de ração, que foi maior para aves alimentadas com óleo de semente de uva nas rações. As fontes energéticas avaliadas não influenciaram a qualidade interna dos ovos. Diante disso, conclui-se que as fontes lipídicas avaliadas neste estudo podem ser utilizadas como ingredientes energéticos nas rações para codornas em postura, sem afetar o desempenho e a qualidade interna dos ovos.

O objetivo do trabalho foi avaliar o desempenho de leitões alimentados com duas fontes de óleos (soja e palma) em associação com maltodextrina e do blend de óleo de palma microencapsulado com maltodextrina, bem como os coeficientes de digestibilidade aparente dessas dietas. Utilizaram-se 162 leitões desmamados aos 21 dias, com peso médio inicial de 5,42 ± 0,55 kg, os quais foram distribuídos em delineamento de blocos ao acaso em três tratamentos e dezoito repetições compostas de três animais.

Os dados de desempenho e digestibilidade foram submetidos à análise de variância, respectivamente, pelo procedimento MIXED e GLM do pacote estatístico SAS, sendo as médias comparadas pelo teste de Tukey (P<0,05). O consumo diário de ração (CDR), ganho diário de peso (GDP) e conversão alimentar (CA) foram avaliados nos períodos de 0 a 16 dias e 0 a 32 dias pós-desmame. Na segunda semana experimental, os coeficientes de digestibilidade aparente (CDA) da matéria seca (MS), proteína bruta e extrato etéreo (EE) foram mensurados pelo método da coleta parcial de fezes. Não foram encontradas diferenças (P>0,05) para o CDR, GDP e CA dos leitões submetidos aos diferentes tratamentos. O CDA da MS foi 4,25% menor (P<0,05) para a dieta com óleo de palma microencapsulado pela maltodextrina em relação à dieta com óleo de soja...(AU)

The performance and digestibility data were submitted to analysis of variance using the MIXED and GLM procedures, respectively, of the SAS package and means were compared by the Tukey test (P<0.05). Daily feed intake (DFI), average daily gain (ADG) and feed conversion (FC) were evaluated from 0 to 16 days and from 0 to 32 days postweaning. In the second week of the experiment, the apparent digestibility coefficients (ADC) of dry matter, crude protein and ether extract were measured by partial feces collection. No differences (P>0.05) in DFI, ADG or FC were observed between piglets submitted to the different treatments. The ADC of dry matter was 4.25% lower (P<0.05) for the diet containing palm oil microencapsulated with maltodextrin compared to the soybean oil diet. The ADC of ether extract was 54% higher (P<0.05) in the soybean oil diet compared to the palm oil diet, which negatively affected the ether extract digestibility coefficient...(AU)

Resumo

Acid oils (AO) are by-products of oil refining for human consumption, and have been used as an alternative energy source to soybean oil (SO) in poultry nutrition. Therefore this systematic review was executed whose were selected 13 studies published on electronic platforms, for the network meta-analysis in order to evaluate the effects of AO use on feed intake (FI), feed conversion (FC) and weight gain (WG) in broilers. The response variables were analyzed using an inverse variance heterogeneity model (IVhet) through the standardized mean difference between birds supplemented with AO vs SO (positive control) and without oils (negative control). The meta-analysis demonstrated that AO supplementation does not affect FC compared to SO, but favors FI compared to non-oil diets. FC is worse in birds fed with acid soy oil (ASO) compared to SO, while 50% ASO + SO mixture is enough to make FC equivalent to SO. Among the most studied acid oils, diets with ASO had better FC compared to diets without oil. Broilers fed diets without oil have lower WG compared to SO or ASO. To maintain the broilers performance, in the SO absence it is preferable to use acid oils rather than use no oil in the diets formulation.

Resumo

The aim was to evaluate the influence of different application forms of soybean oil in diets for Nile tilapia performance. We used 192 fish with average weight of 15.34 ± 0.60 g and average total length of 8.61 ± 2.11 cm. We made isocaloric diets in three application forms: oil after extrusion, oil before extrusion, oil before and after extrusion and one control diet without soybean oil, totaling four treatments with four replicates. We evaluated the performance parameters, filet chemical composition and blood biochemistry. There were no difference (P>0.05) among the three different forms of soybean oil application and the control diet promoted the lowest results (P 0.05) in the performance. Regardless of its application, the inclusion of soybean oil did not influence the analyzed variables, although its use concomitant to a source of carbohydrate has provided better performance of Nile tilapia juveniles.(AU)


O objetivo foi avaliar a influência de diferentes formas de aplicação do óleo de soja em rações, no desempenho de tilápia do Nilo. Utilizaram-se 192 peixes com peso médio de 15,34 ± 0,60 g e comprimento total médio de 8,61 ± 2,11 cm. Foram confeccionadas rações isoenergéticas em três formas de aplicação: óleo pós-extrusão, óleo anterior à extrusão, óleo anterior e posterior à extrusão, além de ração controle isenta de óleo de soja, perfazendo quatro tratamentos com quatro repetições. Avaliaram-se parâmetros de desempenho produtivo, composição centesimal do filé e bioquímicos do sangue. Não houve diferença (P>0,05) entre as formas de aplicação do óleo de soja e a ração controle promoveu os menores resultados (P 0,05) de desempenho produtivo. Independentemente de sua forma de aplicação, a inclusão do óleo de soja não influenciou as variáveis analisadas, embora seu uso concomitante com uma fonte de carboidrato tenha proporcionado melhor desempenho produtivo dos juvenis de tilápia do Nilo.(AU)
