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...
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 کاملThe relationships of body temperature to weight gain, feed consumption, and feed utilization in broilers under heat stress.
Commercial broiler males were used to evaluate body temperature response to heat stress and its relationship to gain, feed consumption, and feed conversion ratio. Individual gain, feed consumption, and feed conversion ratio were obtained from 28 to 49 d in a heat stress environment (32 C) and compared to a 21 C environment. Body temperatures were measured at 28, 35, and 42 d, then daily from 43...
متن کاملEffects 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 کاملNutrient balance and body composition.
The prevalence of obesity in industrialized countries is increasing in spite of decreased energy and fat intakes. This trend might be mainly a consequence of a decline in energy expenditure. It is suggested here that it might also be accounted for by the increasing proportion of protein in the diet, affecting the hormonal status. The nutrient imbalance is particularly apparent in early childhoo...
