Effects of storage time on incubating egg gas pressure, thyroid hormones, and corticosterone levels in embryos and on their hatching parameters
(Poultry Science, 2003-05-01) [Artigo]
Incubating eggs (1,800 total) produced by a commercial flock of Cobb broiler breeders were used to determine the effects of storage duration (3 and 18 d) on gas partial pressure, thyroid hormones, and hatching parameters. ...
Free diet selection by broilers as influenced by dietary macronutrient ratio and corticosterone supplementation. 1. Diet selection, organ weights, and plasma metabolites
(Poultry Science, 2003-01-01) [Artigo]
Male broiler chickens (aged 21 d) were allowed to chose freely for 14 d between three diets in which only one specific macronutrient (protein, lipid, or carbohydrate) was isocalorically substituted for one other macronutrient, ...
Tuberculosis survey of free-ranging marsh deer (Blastocerus dichotomus) in Brazil
(Journal of Zoo and Wildlife Medicine, 2003-12-01) [Artigo]
Esophageal-pharyngeal fluids from 53 free-ranging marsh deer (Blastocerus dichotomus) captured for a research program in the state of Mato Grosso do Sul, Brazil, were assayed for tuberculosis. Total DNA was extracted, ...
Dietary electrolyte balance for broiler chickens under moderately high ambient temperatures and relative humidities
(Poultry Science, 2003-02-01) [Artigo]
Cobb male broiler chicks (1,000) on new litter were used to evaluate effects of dietary electrolyte balance [DEB; Na+K-Cl, milliequivalents (mEq) per kilogram] under tropical summer conditions. Corn-soybean meal-based mash ...
Dietary electrolyte balance for broiler chickens exposed to thermoneutral or heat-stress environments
(Poultry Science, 2003-03-01) [Artigo]
Ross male broiler chicks (n = 480) on new litter were used in a randomized block design with two blocks (environmental rooms) and four treatments having four replicate pens (1.0 × 2.5 m; 15 chicks) each to evaluate dietary ...
