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...
متن کاملUse of residual feed intake in Holsteins during early lactation shows potential to improve feed efficiency through genetic selection1
Improved feed efficiency is a primary goal in dairy production to reduce feed costs and negative impacts of production on the environment. Estimates for efficiency of feed conversion to milk production based on residual feed intake (RFI) in dairy cattle are limited, primarily due to a lack of individual feed intake measurements for lactating cows. Feed intake was measured in Holstein cows durin...

متن کاملEffect 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...
متن کاملOrnithine 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 ...
