Computerized Early Feed Restriction Programs for Various Strains of Broilers

Effects of Early Feed Restriction during Delayed Placement on the Performance and Gut Health of Broilers

An experiment was conducted to investigate the effect of early access to feed and water on the performance of broiler chicks during the first two weeks of life. A total of 64 Ross x Ross 708 broiler chicks were allotted to 3 treatment groups with 3 pens per group and 6 to 9 chicks per pen. Treatment group 1, 2, and, 3 were fasted for 36, 24, or 12 h post-hatch respectively, followed by ad libit...

Effect of early feed restriction and enzyme supplementation on digestive enzyme activities in broilers.

The effect of feed restriction and enzymatic supplementation on intestinal and pancreatic enzyme activities and weight gain was studied in broiler chickens. Quantitative feed restriction was applied to chickens from 7 to 14 d of age. An enzyme complex mainly consisting of protease and amylase was added to the chicken ration from hatching to the end of the experiment. Birds subjected to feed res...

Effect of Feed Restriction on Performance and Immune Response of Two Commercial Broiler Strains

Changes in body composition and adipocyte cellularity of male broilers subjected to varying degrees of early-life feed restriction.

Three experiments were conducted to determine growth performance, body composition changes, and adipocyte characteristics of male broilers subjected to early-life feed restriction. The purpose of Experiment 1 was to determine 42-d growth performance and body composition changes. Treatments used were full-fed control and 50% physical feed restriction during the period 6 to 12 d of age. Experimen...

Ornithine Decarboxylase Expression in the Small Intestine of Broilers Submitted to Feed Restriction and Glutamine Supplementation

Six hundred and forty one-day-old Cobb male broilers were used to evaluate ornithine decarboxylase (ODC) expression in the mucosa of the small intestine. Birds were submitted to early feed restriction from 7 to 14 days of age. The provided feed was supplemented with glutamine. A completely randomized design with a 2 x 2 factorial arrangement was used (with or without glutamine, with or without ...
