Abstract:
Several regimens of feed restriction, calculated to support the maintenance of body weight without any allowance for growth, were applied beginning at the ages of 3 to 11 days for periods of 3 to 7 days using male and female broilers. In males, the 7-day feed restriction treatment resulted in improved feed efficiency on an age basis, or on a body weight basis after body weight had reached .7 to 1 kg. Feed restriction also resulted in a reduction in the amount of abdominal fat at the age of 54 to 59 days without any concomitant reduction in body weight. Within the range tested, 3 to 11 days of age, the initiation of the 7-day restriction treatment did not affect response. Similar responses were obtained in females, but with little benefit in feed efficiency when compared with ad libitum-fed birds on a body-weight basis. Also in females, reduction in 56-day body weight and loss of benefits derived from improved feed efficiency and reduced carcass fat could be avoided if the period of restriction was kept at 3 to 5 days.
