Performan domba lokal jantan yang diberi ransum komplit berbahan baku jerami padi yang mendapat perlakuan cairan rumen

Abstract

Decresing of land for agriculture pushed the exploiting of agricultural and industrial by-products for feedstuff,. Rice straw and onggok represent the by-products that very potential to use for feedstuffs. However these by-products have low digestion value for livestock. Therefore processing of the by-products before use is essensial to increase its quality. The experiment was conducted for 7 weeks lo investigate the effects of feeding diets containing rumen liquor treated-rice straw or rumen liquor treated-onggok on the performance of local male sheeps Twelve local male sheeps (17.75+2.35 kg) were divided into three groups and assigned randomly to one of four dietary treatments. The dietary t re at men ts were Rl: complete ration containing control rice straw and onggok; R2 : complete ration containing automated rice straw and control onggok; R.3: complete ration containing rumen liquor treated rice straw and control onggok; and R4: complete ration containing control rice straw and rumen liquor treated onggok . The diets were offered 3.5% of total body weight while water was offered ad libitum. Parameters measured were feed intake (g/head/day), weight gain (g/head'day), and feed conversion Data from randomized complete block design were analized using AN OVA and if its showed significantly different contras or t agonal test was used. The result showed thai the treatments significantly (P< 0, OS J affected feed intake, weight gain, and feed conversion. R2 and R3 treatments significantly (P<0,0l) increased feed intake compared with R4 and RJ treatment, while between R2 and R3 treatments, and Rl and R4 treatments were not different. Weight gain and feed conversion of sheeps fed R2, R3, and R4 way significantly (P<0,01) higher compared with that of control diet (Rl), but among R2, R3, and R4 were similar. The weight gain and feed conversion of sheeps were 173.5±30.6 and 4, 7±0,6 ; 146.5±41.2 and 5.6+0.8; 136,1 ±41.2 and 5,3+; 68.0+15.6 and 10.2±4.0 for R2, R3, R4, and Rl, respectively. It can be concluded that treament of rumen liquor to rice straw could improve its nutritive quality which ~u as proved by good performance of sheeps fed diets containing rumen liquor treated rice straw.
