Effect of Feed Restriction on Broiler Chicks Prior to Slaughter

Effect 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...

Effect of Feed Restriction Regimes on Growth Performance and Carcass Yield of Broiler Chicks

This study was conducted to evaluate the effect of feed restriction on body weight, body weight gain, feed intake, and feed conversion ratio and carcass traits of broilers. Two hundred and forty one day old Hubbard broiler chicks were randomly distributed into five treatments. Each treatment included six replicates of 8 birds each. The five treatments were as follows: T1( birds were fed continu...

Effect of Posthatch Feed Restriction on Broiler Breast Muscle Devel

The effect of an immediate posthatch growth restriction mediated through a 20% growth restriction the first 2 wk posthatch was studied for its effect on pectoralis major muscle morphological structure and the expression of the myogenic transcriptional regulatory factors, MyoD and myogenin, and the heparan sulfate proteoglycans syndecan-4 and glypican-1. Broiler chicks at hatch were divided into...
