Guanidinoacetic Acid Improves Growth Performance and Gut Health of Broilers Fed Metabolizable Energy‐Reduced Diets

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study was conducted to evaluate the effects of guanidinoacetic acid (GAA) supplementation to diets with different energy levels on growth performance, carcass traits, and gut health status in broiler chickens. A total of 9500 1‐day‐old Ross 308 broilers (equal numbers of males and females) were allocated to 1 of 5 dietary treatments (10 ...

Copper requirements of broiler breeder hens

Poultry Science, 2018
One-hundred-twenty Cobb 500 hens, 20 wk of age, were randomly allocated into individual cages with the objective of estimating Cu requirements. After being fed a Cu deficient diet for 4 wk, hens were fed diets with graded increments of supplemental Cu (0.0; 3.5; 7.0; 10.5; 14; and 17.5 ppm) from Cu sulfate (CuSO4 5H2O), totaling 2.67; 5.82; 9.38; 12.92;

Applied Research Note: Maternal flaxseed diet did not affect body weight of broiler chickens diagnosed with novel avian reovirus and infectious bronchitis

Journal of Applied Poultry Research
SUMMARY: Feeding breeder hens diets enriched with omega-3 fatty acids (n-3 FA) has previously been shown to increase their progeny's immunocompetence. During an experiment to assess the effects of maternal-fed n-3 FA on broiler behavior, broiler chickens

Combination of In Ovo Nutritional Components Improves Embryonic Development, Growth Performance, and Gut Health in Broiler Chickens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of intra‐amniotic administration of combined energy, amino acid, and vitamin sources on embryonic development, post‐hatch growth performance, and intestinal health in broiler chickens. On Day 18 of incubation, 460 fertile Ross 308 eggs were allocated to four groups: non‐injected negative control (NC), saline ...
