Pengaruh Pemberian Probiotik Silase Batang dan Daun Ubi Kayu (Manihot esculenta sp) terhadap Kualitas Karkas Domba Jantan Lokal

Abstract

Carcass quality is one of the main indicators in determining the economic value of local sheep, which is greatly influenced by the type of feed consumed. One potential alternative feed is cassava stems and leaves (Manihot esculenta sp.), which are rich in protein but contain anti-nutritional compounds such as hydrocyanic acid (HCN). The fermentation process with the addition of probiotics is expected to reduce HCN levels while increasing the nutritional value of the feed. This study aims to evaluate the effect of probiotics in cassava stem and leaf silage on the carcass quality of local rams, including slaughter weight, carcass weight, and carcass percentage. The study used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The treatments consisted of P0 (unfermented cassava stems and leaves 5% of body weight), P1 (fermented cassava stems and leaves (EM4 20 ml, NASA 10 ml, MOL 20 ml0 5%) of body weight), P2 (fermented cassava stems and leaves (EM4 10 ml, NASA 20 ml, MOL 20 ml) 5% of body weight), P3 (fermented cassava stems and leaves (EM4 20 ml, NASA 20 ml, MOL 10 ml) 5% of body weight). Data were analyzed using ANOVA and Duncan's further test. The results showed that the provision of probiotics in cassava stem and leaf silage did not have a significant effect (P>0.05) on all observed parameters. The highest average slaughter weight was obtained at P0 (30.83 kg), the highest carcass weight at P0 (12.76 kg), and the highest carcass percentage was also at P0 (41.30%).
