The impact of quantitative feed limitation on broiler female chick production performance

Two hundred sixty female chicks, of the Ross 388 breed, have been acquired. The study participants consisted of two-week-old chicks. Following a random selection of twenty groups, each including thirteen chicks with a mean body weight, the groups were assigned to one of four treatments, with five replicates for each treatment. The research was conducted in the Department of Animal Science within the College of Agricultural Engineering Sciences at the University of Sulaimani, Iraq from September 2, 2023, to November 15, 2023. The treatments included T0, which did not involve removal, T1 Remove feed for 6 hours within 24 hours (from 9 am to 3 pm), T2 feed removal for 9 hours within 24 hours (from 9 am to 6 pm), and T3 feed removal for 12 hours within 24 hours (from 9 am to 9 pm). Between 15 and 42 days of age, there were no discernible fluctuations in? any of the treatments for productive performance markers, except feed intake, which exhibited a significant disparity (P≤0.05). T3 and T2 (control) had the lowest amounts of food consumption were (3683.66 and 3905.75) g, while T0 was (4324.52) g the highest amount. The Production Index and the Economic Figure differed significantly in their characteristics. However, the changes in treatments mostly pertained to the age categories of 15-21, 22-28, and 29-42 days, particularly about live body weight and weight gain. These inequalities affected the attributes that contribute to successful performance. This study aimed to examine the influence of feed deprivation on the efficiency of female broiler chicks at different stages of development.
