1. The use of white striped chicken breasts on the quality of nuggets and hamburgers
Abstract The objective of this study was to evaluate physically and chemically chicken breasts with different degrees of white striping (WS), as well as its effect on the process and quality of nuggets and hamburgers. Chicken breasts fillets were obtained from male chicken broilers weighing approximately 3 kg at the slaughterhouse and classified based on the

2. BEHAVIOR OF BROILERS UNDER THE INFLUENCE OF LED LIGHTING AND MICROMETEOROLOGICAL ELEMENTS
ABSTRACT The objective of this research was to analyze the differences between the food behaviors observed under the factors of production environment, sex and lighting system, using stochastic tools of multivariate analysis. As for the thermal characteristics of the environment, air temperature (T, °C), enthalpy (H, kJ kg-1), and black globe temperature an

3. Effects of Dietary Supplementation with Red Algae Powder (Chondrus crispus) on Growth Performance, Carcass Traits, Lymphoid Organ Weights and Intestinal pH in Broilers
ABSTRACT The aim of this study was to determine the effects of dietary supplementation with red algae powder (Chondrus crispus) on the growth performance, carcass traits, lymphoid organ weights and intestinal pH y in broiler chickens. A total of 300 1-day-old B34 line male broiler chickens were randomly allotted to three treatments, four replicates per treat

4. Reduction of calcium levels in rations supplemented with vitamin D3 or 25-OH-D3 for broilers
ABSTRACT An experiment was carried out to verify the response to the Ca reduction levels of diets with different vitamin D sources on performance, bone mineral deposition, serum concentrations, digestibility, carcass characteristics, and meat quality of broiler chickens in the period from 1 to 42 days reared in thermoneutral environment. A total of 504 male

5. Dietary vegetable oils inclusion on the performance, hormonal levels and hsp 70 gene expression in broilers under heat stress
ABSTRACT. The aim of the present study was to compare the effects of unsaturated and saturated oils on the performance, hormonal levels and hsp gene expression in broiler chickens exposed to heat stress. 300 one-day male broiler chicks were assigned to 4 treatments (Diets containing palm, corn, linseed or olive oils) with 5 replicates. At day 28 of age, 2

6. Evaluation of yeast culture and direct-fed microbial on gut histology and serum components of broilers challenged with suboptimal diets under heat stress
ABSTRACT. The use of antibiotics in feed for growth promotion has been restricted in many countries, thus it is of interest to investigate potential alternatives for enhancing growth performance in birds. An experiment was carried out to evaluate the concurrent use of prebiotic and probiotic on gut histology and some blood chemicals of broiler chickens dur

7. Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four

8. Performance And Economic Viability Of Broiler Chickens Fed With Probiotic And Organic Acids In An Attempt To Replace Growth-Promoting Antibiotics
ABSTRACT The aim of this study was to evaluate diets supplemented with probiotic (Bacillus amyloliquefaciens) and organic acids (lactic, acetic and butyric acid) in attempt to replace the antibiotics and anticoccidial (avilamycin + sodium monensin) growth promoters on performance and economic viability of broilers challenged by Eimeria acervulina, E. maxima

9. Organic trace minerals and calcium levels in broilers' diets to 21 days old
ABSTRACT: This study was undertaken to evaluate the effects of dietary calcium levels and supplementation with organic trace minerals selenium, copper, iron, zinc and manganese on performance, tissue deposition and litter mineral concentration. A total of 2,496 one-day-old male Cobb 500 broilers were randomly assigned to a 3 × 4 factorial experimental desig

10. Growth performance and carcass yield of broiler chickens in response to carbohydrases and its association with phytase
RESUMO O experimento foi conduzido para avaliar o desempenho e o rendimento de carcaça de frangos de corte em resposta à suplementação de carboidrase (Xilanase e Betaglucanase; XB) e à associação de carboidrase com fitase (PHY). Um total de 1.920 frangos de corte, machos, com 1 dia de idade (Cobb 500), foram distribuídos em um delineamento experiment

11. Complexos enzimáticos sobre a energia metabolizável e digestibilidade dos nutrientes do milheto para frangos de corte
RESUMO Objetivou-se avaliar o efeito de complexos enzimáticos sobre a energia metabolizável e o coeficiente de digestibilidade de nutrientes do milheto para frangos de corte. Quinhentos e setenta e seis frangos machos foram distribuídos em 36 gaiolas, com três tratamentos: T1 - composição de milheto sem complexo enzimático; T2 - composição de milhet

12. Comparative Study on Carcass Traits, Meat Quality and Taste in Broiler, Broiler Breeder and Aseel Chickens
ABSTRACT Present study evaluated carcass and meat quality attributes of broilers, broiler breeders and Aseel chickens. Sixty birds from each chicken genotype (broiler, broiler breeder and Aseel chickens; five-wk-old broilers and 60-wk-old Aseel chickens and broiler breeders) were evaluated. Birds were maintained under similar environment for 21 days, and the
