Effect of early feed restriction on metabolic programming and compensatory growth in broiler chickens.
The effect of early feed restriction on metabolic programming and compensatory growth was studied in broiler chickens. A total of 480 female 1-d-old broiler birds (Aconred) were randomly allocated to ad libitum and feed-restricted groups, each of which was replicated 6 times with 40 birds per replicate. Broilers were provided commercial diets. Feed-restricted broilers were deprived of feed for ...
متن کاملFeed Restriction in Broiler Chickens Production
The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
متن کاملEffect of Qualitative and Quantitative Feed Restriction on Growth Performance and Immune Function in Broiler Chickens*
The current study was conducted to investigate the effect of early feed restriction (FR, 8 to 14 d of age) on growth performance and immune function in broiler chickens. Birds were fed corresponding diets from 3 to 35 d of age, which consisted of three phases: starter (3 to 7 d of age), FR (8 to 14 d of age) and re-alimentation (15 to 35 d of age) phases. During the FR period, each group of bir...
متن کاملEffect of early feed restriction in male broiler chicks on plasma metabolic hormones during feed restriction and accelerated growth.
1. Plasma GH was greater (P less than 0.05) on day 12 in ad libitum-fed birds compared to restricted chicks. Conversely, maximum GH levels were found to occur in the nutrient restricted chicks during the period of accelerated growth (day 42). 2. A significant decline in circulating insulin concentrations with advancing age was evident in both ad libitum-fed and restricted chicks. 3. Feed restri...
