Supplemental dietary L-arginine attenuates intestinal mucosal disruption during a coccidial vaccine challenge in broiler chickens.
The present study investigated the effects of dietary arginine (Arg) supplementation on intestinal structure and functionality in broiler chickens subjected to coccidial challenge. The present study was a randomised complete block design employing a 3 × 2 factorial arrangement (n 8) with three dietary concentrations of Arg (11·1, 13·3 and 20·2 g/kg) with or without coccidial vaccine challenge (...
متن کاملInfluence of dietary phytic acid and source of microbial phytase on ileal endogenous amino acid flows in broiler chickens.
The effects of phytic acid and 2 sources of exogenous phytase (bacterial vs. fungal) on the flow of endogenous amino acids at the terminal ileum of broilers were assessed using the enzyme-hydrolyzed casein method. Phytic acid (as the sodium salt) was included in a purified diet at 8.5 and 14.5 g/kg, and each diet was fed without or with a fungal (Aspergillus niger-derived) or a bacterial (Esche...
متن کاملPhytic acid increases mucin and endogenous amino acid losses from the gastrointestinal tract of chickens.
The influence of the form of phytic acid on the regulation of mucin and endogenous losses of amino acids, nitrogen and energy in chickens was investigated. Forty-eight 10-week-old male broilers were grouped by weight into eight blocks of six cages with one bird per cage. Birds received by intubation six dextrose-based combinations of phytic acid and phytase arranged in a 3 x 2 factorial consist...
متن کاملProtein utilization and amino acid digestibility of canola meal in response to phytase in broiler chickens.
The regression method was used in a 14-d broiler chicken study to determine the true ileal digestibility of amino acid (AA) and protein utilization in canola meal (CM, 388 g of CP/kg) without or with added phytase. Experimental treatments consisted of 2 factors, phytase at 2 levels (0 or 1,500 phytase units/kg) and CM at 3 levels (125, 250, or 375 g/kg). Birds received a standard starter diet f...
متن کاملIleal Amino Acid Digestibility Assay for the Growing Meat Chicken - Assessment of a New Ileal Amino Acid Digestibility Assay for Broiler Chickens
The aim of the study was to evaluate the accuracy of ileal amino acid digestibility coefficients in dietary formulation for broiler chickens. Two relatively poor quality protein sources, a meat-and-bone meal and a dried blood meal were used. The meals were subjected to the ileal assay and respective mean coefficients of digestibility of 0.58 and 0.67 were found for the first-limiting amino acid...
