ABSTRACT
This study was conducted to determine the effect of rearing broilers in positive pressure barns on the performance of Lohmann strain broilers. The study used one hundred and eighty Lohmann unsex broilers reared for 4 weeks feeding with commercial feed produced by PT. Japfa Comfeed Indonesia Tbk. The study was designed using a completely randomized design using 180 chickens. All chickens were divided into three groups with six replicates each which were the first group was reared in a closed house, the second and third groups were reared in positive pressure and open houses. Each replicate, in each treatment, was reared in a different barn plot with the number of 10 chickens/m2 of the barn area. The results showed that feed consumption, body weight, weight gain and carcass weight of the broiler group reared in positive pressure was higher than that of the open house group and lower than that of the closed house group (P<0.01). The feed conversion of the broilers reared in positive pressure was lower than that of the open house and higher than that of the closed house (p<0.01). It is concluded that the use of positive pressure barns in hot humid climates was better than the use of open houses. Therefore, a positive pressure enclosure system was recommended to be applied.
