Abstract
This experiment was conducted to study the effect of early feed restriction by lighting program on compensatory growth, productive and physiological performance of broilers . A total of 600 unsexed Arbor Acres one-day old broiler chick were randomly distributed into four treatment groups and named (T1 , T2 , T3 and T4). Chicks in T1 were used as control group and reared with continuous light (24 h. daily) throughout the experimental period. Chicks in T2 , T3 and T4 were reared under 12 h. light daily during the period 1-14 , 4-14 and 4-21 days of age respectively . After that all groups were subjected to continuous lighting program.
The data showed that body weights of birds at 7 weeks of age were not statistically different between T1 , T2 and T3 due to the compensatory growth in last two treatments. However , the body weight in T4 were significantly (P > 0.01) decreased at the same age. Light restriction program showed a significant (P > 0.01) decrease in feed consumption , total mortality , and mortality due to ascitis and sunden death syndrome (SDS). Feed conversion ratio, Production Index (PI) , and economic figure (EF) were also significantly (P > 0.01) improved by lighting program . However , blood characteristics and antibody titer against Newcastle disease virus were not changed significantly by the lighting program.
