ABSTRACT
Retrospective data from 18 tunnel-ventilated and 41 conventional houses in Barbados were evaluated in order to compare the effects of the two types of housing using the following indices feed conversion ratio at 1500 grammes (FCR 1500), European Production Efficiency Factor (EPEF), and net income per bird (NIPB). The data were obtained from the records of 200 and 282 grow-outs for tunnel-ventilated and conventional houses, respectively. The effects of season of placement and month of placement on the above performance variables were also evaluated. The analyses revealed that the performance variables NIPB, EPEF, and FCR 1500 were superior for tunnel -ventilated housing (P=0.02, 0.0001 respectively); were less variable from month to month for tunnel- ventilated housing; and except for NIPB, were better when birds were placed during the dry season (P=0.08, 0.0005 and 0.007 respectively). Financial anlaysis also showed that tunnel -ventilated house was more profitable venture than the conventional house. The net profit margin (15.38vs 3.59%) net profit per kg, (0.51 vs 0.12 BDS$, (BDS$1.00~ US $0.50)), and net profit per m squared (94.83vs13.13BDS$) were also higher for the tunnel-ventilated house.
