Abstract
The effects of four stocking rates (0.070, 0.093, 0.116 and 0.140m2/ bird) on the performance of two hybrids of commercial broilers were investigated. There were significant hybrid effects on initial and final body weights (P< 0.01) and on feed efficiency (P <0.05) but not on average daily gain and feed consumption and mortality. Stocking effects which were not significant for initial body weight, feed efficiency and mortality were highly significant for final body weight, average daily gain and feed consumption, (P < 0.01). There were significant interactions between hybrid and stocking rate for average daily gain (P <0.01) and mortality (P < 0.05). It is suggested that in the humid tropics, the stocking rates of 0.116 and 0.140m2/ bird would be appropriate for rearing broilers. The results of the study also showed that different hybrids do vary on space requirements in respect • of certain production traits.
