Effects of dietary protein source and level on intestinal populations of Clostridium perfringens in broiler chickens.
Two experiments were conducted to examine the effect of the level of dietary crude protein and protein source on intestinal populations of Clostridium perfringens in broilers. In experiment 1, 6 groups of 12 birds were fed diets containing 230,315 or 400 g/kg crude protein with soy protein concentrate (SPC) or low-temperature-dried fishmeal as the major protein sources in a 2 x 3 factorial arra...
متن کاملEffect of dietary fat sources on fatty acid deposition and lipid metabolism in broiler chickens.
The hypothesis tested was that dietary vegetable fats rich in saturated fatty acids, when compared with a vegetable oil rich in linoleic acid, increase fat deposition in broiler chickens and affect synthesis or oxidation, or both, of individual fatty acids. Diets with native sunflower oil (SO), a 50:50 mix of hydrogenated and native SO, palm oil, and randomized palm oil were fed to broiler chic...
متن کاملEffect of Dietary Lead on Intestinal Nutrient Transporters mRNA Expression in Broiler Chickens
Lead- (Pb-) induced oxidative stress is known to suppress growth performance and feed efficiency in broiler chickens. In an attempt to describe the specific underlying mechanisms of such phenomenon we carried out the current study. Ninety-six one-day-old broiler chicks were randomly assigned to 2 dietary treatment groups of 6 pen replicates, namely, (i) basal diet containing no lead supplement ...
متن کاملEffect of Dietary Antimicrobials on Immune Status in Broiler Chickens
This study evaluated the effects of dietary anticoccidial drugs plus antibiotic growth promoters (AGPs) on parameters of immunity in commercial broiler chickens. Day-old chicks were raised on used litter from a farm with endemic gangrenous dermatitis to simulate natural pathogen exposure and provided with diets containing decoquinate (DECX) or monensin (COBN) as anticoccidials plus bacitracin m...
متن کاملDietary omega-3 polyunsaturated fatty acid does not influence the intestinal microbial communities of broiler chickens.
The capacity for n-3 polyunsaturated fatty acids (PUFA) to improve broiler chicken growth, influence the intestinal microbial communities, and modify the PUFA content of meat was studied. Male Cobb 500 chickens were fed 1 of 4 diets from hatch: control (standard diet with no additives), ZnB (standard diet with added antibiotics), 2% SALmate (standard diet with 2% SALmate, which is composed of 4...
