A hipospadia é oresultado de falha no desenvolvimento em que não ocorre a fusão normal das dobras genitais e intumescência genital, o que causa desenvolvimento anormal da uretra peniana, do pênis, prepúcio e/ou escroto. O objetivodeste relato é descrever um caso de hipospadia peniana de um canino macho, sem raça definida (SRD), de oito meses deidade, atendido no Hospital Veterinário da Universidade Federal Rural da Amazônia, na cidade de Belém/Pará, detalhando os procedimentos cirúrgico e anestésico utilizados para resolução do caso. Ao chegar ao hospital, o animal foi submetido ao exame físicoinicial no qual observou-se uma deformidade na região perianal por onde drenava a urina e uma abertura na região prepucial. A partir disso, foi solicitada a uretrocistografia retrógrada para complemento diagnóstico da hipospadia e seu comprometimento ao sistema urinário interno. Diante disso, foi realizado procedimento cirúrgico reconstrutivo e orquiectomia terapêutica, alcançando permitindoa resolução do caso e a recuperação completa do animal. Considerando que essa deformidade impossibilita a capacidadesexual generandi, a resolução recomendada é a cirúrgica, na qual o prognóstico é bom, possibilitando qualidade de vida ao animal.(AU)

Hypospadias is the result of developmental failure where normal fusion of the genital folds and genital tumescence does not occur, which causes abnormal development of the penile urethra, penis, foreskin and/or scrotum. The objective of this report is to describe a case of penile hypospadias in an eight-month-old male mixed breed (SRD) canine, treated at the Veterinary Hospital of the Federal Rural University of Amazônia, in the city of Belém/Pará, detailing the procedures surgical and anesthetic used for resolution of the case. Upon arrival at the hospital, the animal underwent an initial physical examination in which a deformity was observed in the perianal region through which urine drained and an opening in the preputial region. From this, a retrograde urethrocystography was requested to complement the diagnosis of hypospadias and its commitment to the internal urinary system. In view of this, a reconstructive surgical procedure and therapeutic orchiectomy were performed, allowing the resolution of the case and the complete recovery of the animal. Considering that this deformity prevents the sexual capacity generandi, the recommended resolution is surgery, in which the prognosis is good, allowing quality of life for the animal.(AU)

Beneficial Impact of Hypercapnic Conditions During Early Incubation on Broiler Hatchability. Embryo Mortality and Postnatal Performance

We assessed the extent to which CO2 levels altered different hatching and chick parameters. In Experiments 1 and 2, a total of 16,184 eggs from Cobb 500 breeders were incubated in single stage incubators under three different conditions: (a) standard ventilated incubator (CON, Exp.1 and 2); (b) increasing CO2 levels during the first 10 days of incubation until 0.7% (V7000, Exp. 1) and (c) until 0.8% (V8000, Exp. 2). High levels of CO2 improved hatchability, possibly due to lower embryo mortality from ED18 to ED21. Internal and external pipping in experiment V8000 started later than in CON; nevertheless, the hatch still occurred before in V8000 as a result of the shorter durations of external pipping and hatch. In Experiment 3, a total of 12,138 eggs from Cobb 500 were incubated in single stage incubators under three different conditions: (a) standard ventilated incubator (CON); (b) increasing CO2 levels until 1.0% with ventilation (V10000); and (c) increasing CO2 levels until 1.0% without ventilation (NV10000). Hypercapnic conditions led to better hatchability and lower embryo mortality from ED18 to ED21. Internal pipping started earlier in NV10000, but only V10000 differed from CON in terms of the average time for hatch. Hypercapnic groups also showed shorter durations of external pipping and hatch when compared to CON. Post-hatch analysis revealed no differences among incubation conditions in terms of body weight gain, feed conversion ratio, mortality by sudden death syndrome, and production factor. Nevertheless, V10000 showed a lower mortality by ascites and a better viability when compared to CON, while NV10000 presented a higher mortality by other causes. Altogether, our findings indicate that in addition to not being detrimental to embryo survival, high CO2 levels reduce embryonic mortality at 18-21 days of incubation and increase hatchability.(AU)

Interspecific variations in external and internal egg quality among various captive avian species from Punjab, Pakistan

Abstract Present study was planned to determine variations in external and internal quality egg parameters of different avian species including ostrich Struthio camelus, ducks Anas platyrhynchos, chicken Gallus gallus, turkeys Meleagris gallopavo and grey francolin Francolinus pondicerinus. All the birds were kept under similar rearing conditions. A total of 150 eggs were collected for each species to record external features of these eggs. Statistically significant (p 0.05) variations were recorded in egg weight, egg length and egg width between ostrich, ducks, chicken, turkey and quail eggs. Significantly (p 0.05) higher egg weight, egg length and egg width was observed for ostrich eggs while the same was lowest for grey francolin eggs. Similarly, significantly (p 0.05) greater shape index and egg volume values were observed for ostrich eggs while lowest shape index values were recorded for turkey eggs and egg volume was lowest for grey francolin. Significantly, higher (p 0.05) values of egg density were noted for eggs of the quail and the same were lowest for ostrich eggs. Non-significant variations in egg density values were observed between eggs of the ducks, chicken, turkey and grey francolin. It has been concluded that the positive correlations between the internal and external egg quality traits indicated that the traits can be improved through selection.

Performance and egg qualities of laying japanese quails fed yam peel meal based diets with enzymes complex+yeast supplementation / Performance and egg qualities of laying japanese quails fed yam peel meal based diets with enzymes complex+yeast supplementation

A 10-week experiment was conducted to evaluate the combined effect of enzyme complex + yeast (Maxigrain®, MXG®) supplementation of sun-dried yam peel meal (YPM) based diet of laying Japanese quails (Coturnix coturnix japonica) on performance and egg quality. A total of 240, seven-weeks old quails were distributed in a completely randomize design with four dietary treatments and five replicates of 12 quails each. Diet 1 served as the control diet without YPM while diet 2, 3, and 4 contained 25, 50, and 75% YPM with MXG® supplementation (1g per kg), respectively. MXG® supplementation in YPM diets improved (p < 0.05) egg mass and feed conversion per egg. Increasing levels of YPM with MXG® supplementation did not show any effect (p > 0.05) on internal and external egg quality attributes except for eggshell weight and thickness which was higher (p < 0.05) in quails fed 75% YPM diet. It was concluded, therefore, that the utilization of YPM as an alternative dietary ingredient with MXG® supplementation can be tolerated in the diets of laying Japanese quails up to 75% inclusion level without any negative effect on productive and egg quality performance.

Natural and synthetic pigments in sorghum-based diets for laying hens

The objective of this work was to evaluate the supplementation of yellow natural pigment levels based on Marigold Flower extract (2%) and yellow synthetic pigment (Carophyll Yellow 10%) in sorghum-based rations for commercial laying hens and their influence on bird performance and egg quality. A completely randomized design was adopted with 5 treatments, 6 replicates, and 5 laying hens in each repetition. The treatments evaluated were: Sorghum based diet without supplementation with pigmentant - Negative Control; 150 g t-1 of Yellow Natural Pigment feed; 300 g t-1 of yellow natural pigment feed; 450 g t-1 of yellow natural pigment feed; 25 g t-1 of yellow industrial pigment feed. The Tukey test was applied at 5% for the analysis of the variables of performance and quality of the eggs. The variables related to external and internal egg quality and poultry yield performance did not present significant results (p > 0.05). Only the variable color of the yolk obtained significance (p < 0.01), with an increase according to the number of pigments included in the diet. Sorghum can be used together supplementation of natural and synthetic pigments in the diet to improve yolk pigmentation. It is recommended to include 450g t-1 of natural marigold flower pigment feed (2%) in sorghum-based diets for better pigmentation of the yolk in place of 25 g t-1 of yellow synthetic pigmented, by improving the color of the yolk and not interfering in the productive performance of the laying hens and the quality of the eggs.(AU)

Comparative Study of Egg and Meat Quality of Guinea Fowl under Different tropical regions: A Review

Guinea fowl have several advantages over chickens. These birds are highly valued for their meat and eggs, particularly in tropical regions. They are currently in many parts of the world. Recently, the demand for guinea fowl meat has increased because it is considered a high-quality protein source. In addition, their eggs are delicious and considerably better than those of chickens. Guinea fowl eggs are valued for their thick shells, and longer shelf life, and it has premium prices compared with commercial and indigenous chickens. Chicken eggs have been well studied for egg and meat quality. However, such information isn't so sufficiently documented in other poultry species. Despite the interest in guinea fowl production, it is vital to take cognizance of the fact that there is a lack of information on the production and quality of guinea fowl products, in contrast to commercial chickens. Therefore, the present review aims to assess the egg and meat quality of Guinea fowl in different tropical regions. The main results of the current study showed that the external egg quality characteristics, mainly (egg weight, shell percentage, and shell thickness), and internal egg quality traits, mainly (albumen weight, haugh unit, yolk height, and yolk color) of Guinea fowl differed under different tropical regions. Concerning carcass characteristics, a clear difference was observed in dressing percentage and breast percentage of Guinea fowl in various tropical areas. A similar trend was observed for the meat color.(AU)

Performance and egg qualities of laying japanese quails fed yam peel meal based diets with enzymes complex + yeast supplementation

A 10-week experiment was conducted to evaluate the combined effect of enzyme complex + yeast (Maxigrain®, MXG®) supplementation of sun-dried yam peel meal (YPM) based diet of laying Japanese quails (Coturnix coturnix japonica) on performance and egg quality. A total of 240, seven-weeks old quails were distributed in a completely randomize designwith four dietary treatments and five replicates of 12 quails each. Diet 1 served as the control diet without YPM while diet 2, 3, and 4 contained 25, 50, and 75% YPM with MXG®supplementation (1g per kg), respectively. MXG®supplementation in YPM diets improved (p < 0.05) egg mass and feed conversion per egg. Increasing levels of YPM with MXG®supplementation did not show any effect (p > 0.05) on internal and external egg quality attributes except for eggshell weight and thickness which was higher (p < 0.05) in quails fed 75% YPM diet. It was concluded, therefore, that the utilization of YPM as an alternative dietary ingredient with MXG®supplementation can be tolerated in the diets of laying Japanese quails up to 75% inclusion level without any negative effect on productive and egg quality performance.(AU)

En el examen externo, la lesión más frecuente fue la hemorragia de la piel (50%), las aletas (50%), las branquias (25%) y la cavidad oral (12,5%), mientras que en el examen interno predominaron la esplenomegalia (75%) y la hemorragia renal (50%). El análisis físico-químico mostró alteraciones significativas en las bases volátiles totales (BTV), lo que hace que el alimento no sea apto para el consumo según la legislación vigente. Las alteraciones observadas configuran la pérdida de calidad del pescado, el deterioro y las lesiones sugestivas de enfermedad zoonótica. El pescado comercializado en los distritos de Ipaussu y Botucatu no cumplía con los estándares de frescura requeridos para el consumo establecidos por la legislación brasileña.(AU)

Pectus excavatum ­ Correção cirúrgica utilizando tala externa de poliuretano fabricada com tecnologia de impressão 3D / Pectus excavatum ­ Surgical correction, using polyurethane external splint made with 3D printing technology

Objetivou-se relatar o emprego de uma tala externa confeccionada com material de poliuretano e cobertura interna de neopreme na reparação cirúrgica do pectus excavatum em um felino jovem. O felino apresentava deformidade anatômica congênita na região do externo e sinais clínicos respiratórios. Imagens avançadas de tomografia foram utilizadas para moldar a tala impressa com tecnologia tridimensional. Esta alternativa possibilitou melhor planejamento cirúrgico e, com isso, conforto para o paciente, além da qualidade própria do material de poliuretano que é levemente maleável, o que permitiu melhor moldagem e expansão torácica durante a respiração. A tala se provou resistente o suficiente para suportar a tração ocasionada pelos fios de sutura e possibilitou o reposicionamento adequado do osso esterno ao mesmo tempo que se mostrou confortável e acarretou mínimas lesões ao paciente.

The aim of this paper was to report the use of an external splint made of polyurethane material and internal neopreme covering in the surgical repair of a pectus excavatum in a young feline. The feline exhibited a congenital anatomical deformity in the external region and clinical respiratory signs. Advanced CT images were used to shape the 3D-printed splint. This alternative allowed better surgical planning and, therefore, comfort for the patient, this because to the quality of the polyurethane material, which is slightly malleable, and allowed for better molding and chest expansion during breathing. The splint proved to be strong enough to withstand the traction caused by the suture threads and allowed the proper repositioning of the sternum, at the same time it was comfortable and caused minimal injuries to the patient.

Performance and egg qualities of laying japanese quails fed yam peel meal based diets with enzymes complex + yeast supplementation

A 10-week experiment was conducted to evaluate the combined effect of enzyme complex + yeast (Maxigrain®, MXG®) supplementation of sun-dried yam peel meal (YPM) based diet of laying Japanese quails (Coturnix coturnix japonica) on performance and egg quality. A total of 240, seven-weeks old quails were distributed in a completely randomize design with four dietary treatments and five replicates of 12 quails each. Diet 1 served as the control diet without YPM while diet 2, 3, and 4 contained 25, 50, and 75% YPM with MXG® supplementation (1g per kg), respectively. MXG® supplementation in YPM diets improved (p < 0.05) egg mass and feed conversion per egg. Increasing levels of YPM with MXG® supplementation did not show any effect (p > 0.05) on internal and external egg quality attributes except for eggshell weight and thickness which was higher (p < 0.05) in quails fed 75% YPM diet. It was concluded, therefore, that the utilization of YPM as an alternative dietary ingredient with MXG® supplementation can be tolerated in the diets of laying Japanese quails up to 75% inclusion level without any negative effect on productive and egg quality performance.(AU)

Production Performance and Egg Quality of Laying Hens as Influenced by Genotype and Rearing System

ABSTRACT The aim of this study was to evaluate the effect of rearing systems and genotypes on production performance and egg quality. Isa Brown and New Hampshire genotypes were used in this study. These two genotypes were housed in floor and organic rearing systems. During the experimental period, which lasted one year (52 weeks), the following production performance parameters were recorded: egg production, daily egg mass, feed consumption, feed conversion efficiency, and mortality. Fifteen eggs per group were collected for analysis at 64 weeks of hen age. These samples were evaluated for external parameters (egg weight and egg shape index), internal parameters (albumen height, Haugh unit, and the proportions of albumen, yolk and shell), eggshell quality parameters (shell thickness, shell deformation and shell breaking strength), and eggs chemical composition (dry matter, minerals, protein and lipids). Generally, Isa Brown hens had better production performance than New Hampshire hens. At the same time, organic New Hampshire layers performed better than floor-reared ones. Genotype had a significant effect on all ten egg quality parameters (external, internal and eggshell quality), rearing system independently affected only egg weight, and the interaction of the observed factors significantly influenced seven parameters. Genotype had a significant effect on three of the four chemical composition parameters, while no significant effect of the rearing system was established on the chemical composition of eggs. The rearing system x genotype interaction significantly affected the eggs protein content.

Effects of Storage Period, Marketing Channels and Season on Internal and External Quality of Commercial Table Eggs Marketed in Riyadh City (Saudi Arabia)

Very sparse information is available regarding quality of commercial Table eggs marketed in Riyadh city. The objective of the current study was to evaluate egg quality by determining the internal and external traits of commercial Table eggs marketed in different marketing channels during the summer and winter. Commercial eggs (n = 1440) were bought from four different supermarkets and groceries during the winter and summer season 2018- 2019. A total of 30 eggs were collected monthly from each marketing channel in the winter and summer. Then, individually numbered, weighed and randomly broken down into three empirical groups and stored for 0, 7 or 14 days. The outcomes show that seven and fourteen days of storage led to significant decrease in Haugh unit values, yolk index, specific gravity, shell thickness and shell weight per unit of surface area, and increase in yolk color grade, yolk albumin ratio, yolk and albumin pH and air cell depth. Eggs acquired from supermarkets had significantly higher Haugh unit values and yolk index, and lower yolk color grades, shell density and air cell depth, than those bought from groceries. Eggs that were collected in winter season are found to have significantly higher Haugh unit values, yolk index, specific gravity, shell thickness, shell density, shell weight per unit of surface area and yolk color, and lower, yolk albumin ratio, air cell depth, albumin and yolk pH than those acquired in the summer season eggs. This study showed that the storage period, marketing channels and season play a significant role in affecting quality traits of Table eggs, also those procured from supermarkets and in the winter presented better quality than those found in groceries or in the summer, respectively.(AU)

Assessment of Egg Quality in Native and Foreign Laying Hybrids Reared in Different Cage Densities

This study aimed to compare the eggs of the native-Turkish Atak-S (A-S) hybrid and the foreign brown layer Isa Brown (IB) and white layer Novogen White (NW) hybrids reared in two different cage densities (468.75 cm2/hen and 312.50 cm2/hen) in terms of the internal and external quality parameters of the eggs. A total of 540 hens including 180 from each genotype were used. To determine the egg quality characteristics, one randomly selected egg was taken out of each cage every 4 weeks in the yield period of 24-68 weeks, and analysis were carried out. A total of 648 eggs were used. In the study, the effect of genotype on all parameters was found to be significant. The shell thickness, Haugh unit and albumen index were lower in the Atak-S hybrid. In the white laying hens, the Haugh unit, albumen index and eggshell destruction strength values were higher, while the meat and blood spots and yolk color values were lower. Cage density did not create a significant effect on any parameter except for the blood and meat spot ratio. Age has a significant effect on the egg weight, shape index, Haugh unit, albumen index and yolk index. Consequently, as the native hybrid had similar destruction strength values to the others despite its lower shell thickness, and it had a Haugh unit showing good quality based on the food codex despite lower values than the others, it was concluded that it could compete with the foreign hybrids in terms of egg quality.(AU)
