13. 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

15. 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

16. Grapeseed Meal Used as Natural Antioxidant in High Fatty Acid Diets for Hubbard Broilers
ABSTRACT The 7-week feeding trial evaluated the effect of 2% grapeseed meal used as natural antioxidant in the diets for slow-growing Hubbard broiler chicks, aged 14 days. The chicks were weighed individually and assigned to two groups (C and E), with 40 chicks per group, housed under conditions of temperature, humidity and light regimen according to the hyb

17. Co-Supplementation of Dietary Seaweed Powder and Antibacterial Peptides Improves Broiler Growth Performance and Immune Function
ABSTRACT The feasibility of Laminaria japonica powder (LJP) combined with cecropin as a dietary supplement to enhance broiler growth performance and immune function was evaluated in this study. In total, 648 one-day-old Arbor Acres broiler chicks were randomly distributed into nine numerically-equal treatment groups: T1 (control group; fed a basal diet); T2

18. The Dietary Inclusion of Chickpea Seeds (Cicer Arietinum L.) Influences the Thermal Properties of Muscle Proteins, But Not the Texture of Drumstick Muscle in Broiler Chickens
ABSTRACT In this study, the effect of replacement of soybean meal with raw chickpea seeds as a primary protein source in the diet of broiler chicks on physical properties of drumstick muscle (m. gastrocnemius) was examined. One-day-old Ross 308 broilers (n=160) were fed soybean meal (n=80) or raw chickpea seeds (n=80) as a primary protein source for 42 days.

19. Effect of an Enzymatic Blend and Yeast on the Performance, Carcass Yield and Histomorphometry of the Small Intestine in Broilers from 21 to 42 Days of Age
ABSTRACT The present study was conducted to evaluate the performance, carcass yield, and histomorphometry of the small intestine of broilers fed yeast sugarcane supplemented with enzymatic blend from 22 to 42 days of age. Seven hundred broiler chicks were distributed in a completely randomized design in a factorial design (2x3+1), two levels of the enzyme bl

20. 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

21. Post-hatch fasting and infectious bronchitis vaccination affect growth, gastrointestinal development, and morphometric parameters of the small intestine of broiler breeders up to three weeks of age
ABSTRACT The influence of fasting and vaccination against infectious bronchitis (IB) on growth, gastrointestinal development, and morphometric parameters of the small intestine of newborn broiler breeders was investigated. Weight gain (WG), feed conversion ratio (FCR), gastrointestinal visceral growth, residual yolk sac, and morphometric parameters of the sm

24. Vegetable Waste Inclusion in Broiler Diets and its Effect on Growth Performance, Blood Metabolites, Immunity, Meat Mineral Content and Lipid Oxidation Status
ABSTRACT The aim of present study was to evaluate the effect of feeding vegetable waste (VW) to broilers on their growth performance, serum chemistry, immune status, meat mineral content and lipid oxidation status. For this purpose, 100 one-day-old chicks (Cobb 500) were acquired from a commercial hatchery and allocated according to a completely randomized d
