Effect of bio activator use on corn cobs as a complete feed on performance and digestibility of local sheep

Abstract

This study was conducted in Binjai City in two stages for 3 months. Stage I aims to determine changes in the chemical components of corn cobs which are fermented with various bioactivators. This study used a completely randomized design (CRD) with 5 treatments and 3 replications. The results of the diversity analysis showed the use of various bio activators significantly (P <0.05) on crude protein content and crude fibre content. Stage II aims to determine the response of local sheep that are fed complete based on corn cobs fermented on feed performance and digestibility. This study used 20 local rams with an average weight of 19.82 kg using a completely randomized design (CRD) with 5 treatments and 4 replications. The results showed that corn cobs administration had a significant effect (P <0.05) on feed performance and digestibility. The highest income over feed ratio is found in the P4 treatment of Rp. 334,400. From this study it can be concluded that the best treatment is found in P4 treatment which has the lowest feed conversion value and the most economical IOFC value.
