Abstract

This research aimed to study the performance of broiler raised in 3 stair floors. This research had been done from 09 September to 12 Oktober 2016 at Purwosari, Pasuruan. The data of performance was obtained from a poultry house which divided into 3 floors. The brooding period was given for 2 weeks in 2 nd floor, on 15 th days the chicken were separated into 1 st and 3 rd floor with the same house density. The obtained data was analyzed using T-test (independent samples T-test) to see the difference in between. The result of this research showed that there were highly significant differences on body weight gain, slaughter weight, and feed conversion ratio of broiler between 1 st and 3 rd floor. However, the differences floor did not contribute to differences on feed consumption (2.357 g/bird on 1 st floor and 2.351 g/bird on 3 rd floor). The body weight gain of broiler at 1 st floor (1.293±96.52 g/bird) was lower than 3 rd floor (1.331±82.77 g/bird). The final weight of broiler at 1 st floor (1.780±90.6 g/bird) was lower than 3 rd floor (1.818±81.8 g/bird). Feed conversion ratio of broiler at 1 st floor (1.83±0.14) was higher than 3 rd floor (1.77±0.11). The conclusion of this research was that the performance of broiler raising at 3rd floor has better performance than those at 1 st floor. It is suggested to further research to determine the best production performance of broilers reared on the 1 st floor, 2 nd floor and 3 rd floor. Keywords: depletion, microclimate, stair floors
