Studies on Feed Restriction of Pullets

Effects of Feed Restriction on Production Performance and Carcass Characteristics of Koekoek Chickens in Ethiopia

This study was conducted to examine the effects of feed restriction on production performance as well as traits relating to egg and carcass yield in Potchefstroom Koekoek dual purpose chicken bred under Ethiopian conditions. A total of 240 one-day-old dual purpose Koekoek chicks were randomly distributed into 12 experimental pens, representing 4 feeding treatments to evaluate the performance of...

Effect of feed restriction on compensatory growth response of young male goats

Forty eight 8-month-old male goats were divided into three groups. In each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. Restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. At the end of restriction period, the restricted goats were offered the same ration ...

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...
