Abstract
 

The objective of the present study was to determine the effect of quantitative feed restriction on the growth performance and livability of broiler strains. It also aimed at estimating the economics of production of the different treatments applied in order to suggest the cheapest and profitable means of growing broiler chickens. A total number of 90 day-old broilers of Anak Titan and Arbor Acres were randomly allocated to three treatments: ad libitum (T1), 85% ad libitum (T2) and 75% ad libitum (T3)from 11th -18th days of age. Thereafter, the birds were given full feed until the age of 49 days. Treatments were replicated three times with five birds per replicate. Data on body weights and feed consumed were recorded on weekly basis to the seventh week. It was evident from this study that feed restriction during second week post-hatch has no detrimental effects on the livability, final body weight and weight gain of the two strains of broilers. Feed cost which was a major component contributed 46% to the total cost of production. With regard to feed restriction regimen, control and 85% ad libitum birds were at par in body weight and weight gain, but superior to 75% ad libitum birds. In addition, birds fed 85% ad libitum had the least feed conversion ratio and recorded highest net profit per bird when compared with control and 75% ad libitum. Average net profit per bird for birds fed 85% ad libitum was $2.598, while control and 75% ad libitum were $2.584 and $1.906, respectively. It is suggested that for maximization of feed utilization and profitable broiler meat production in the humid tropics, Arbor Acre and 85% ad libitum for short-term during starter phase could be considered.
