Performa produksi Broiler starter akibat cekaman panas dan perbedaan awal waktu pemberian pakan

Abstract

The study was conducted to know performance (feed consumption, body weight gain and feed conversion) response of broiler starter due to heat stress and different initial feeding. The material used in this study was 64 male DOC broilers of Lohmann strain with average of initial weight 47,98 ± 2,24 g. The experiment was designed based on Randomized Blok Design with 2x2 factorial and four replications. The treatment combinations as follow: S1W1= low temperature, feeding 12 hours post-hatching; S1W2 = low temperature, feeding 24 hours post-hatching; S2W1= high temperature, feeding 12 hours post-hatching; S2W2 = high temperature, feeding 24 hours post-hatching. The data were analyzed by using ANOVA. If there was significant effect (P<0.05) or very significant effect (P<0.01) followed by Duncan’s test. The result showed that feed consumption had very significant effect (P<0.01) due to heat stress treatment and initial feeding. The initial feeding treatment had significant effect (P<0.05) to the body weight gain and feed conversion. It concluded that heat stress affected negatively to the performance of broiler starter. The initial feeding has significantly affected to the feed consumption, body weight gain and feed conversion in broiler starter.
