Daftar Isi:
- The present experiment was conducted to evaluate effect of protein and katuk (sauropus androgynus) leaves extract supplementation levels on carcass qualites of broilers. Seventy two broilers aged 21 days of age were distributed to 6 treatment groups of 3 replicates with 4 birds each. Factorial completely randomized experimental design (2x3) was used in the present study. There were two levels of katuk leaves extract (4,5 g/kg and 9 g/kg) and three levels of protein (19%, 17%, and 15%). Variables observed were carcass color, carcass weight, meat bone ratio, cooking loss, and drip loss. Experimental results showed that supplementation level of katuk leaves extract significantly affected carcass color (P<0,05), but it had no effect (P>0,05) on carcass weight, meat bone ratio, cooking loss and drip loss. Level of protein had no effect (P>0,05) on carcass color, cooking loss and drip loss, but it was significant affect carcass weight (P<0,05) and meat bone ratio (P<0,01). In conclusion, supplementation level of katuk leaves extract on 9 g/kg improve carcass color. 15% protein containing diets reduced carcass weight and meat bone ratio. No interaction was found between protein level and katuk leaves extract supplementation levels on improving carcass qualities.
