The Effect of Using Different Sources of Carbohydrates to Feed Efficiency on Indigenous Thin Tailed Male Lamb

Abstract

Differences in structure and bonding material feed sources of carbohydrates causes the difference fermentability and digestibility in the rumen and post-rumen. Thus, the utilization rate and feed ef ciency were also different. The objective of this experiment was to study the feed ef ciency of various sources of dietary carbohidrates on indigenous thin tailed male lamb. The experiment design was randomized block design 4x4. Sixteen thin tailed male lamb with average body weight 15+2.07 kg maintained for 12 week. The 4 treatment applies in ration (CP 13%, TDN 68%) namely, P1= complete feed containing rice bran 25% DM, P2= complete feed containing corn 25% DM, P3= complete feed containing cassava waste meal 25% DM, P4 = complete feed containing sorghum 25% DM. The result showed that the fed containing different sources of carbohydrates signi cantly effect on dry matter intake, average daily gain (ADG) and feed ef siency (P<0.01). Feed ef ciency generated in this study were 15.75 (P1); 17.96 (P2); 15.55 (P3) dan 19.09% (P4). Based the result on this study, it could be concluded that the feed containing carbohydrates from grain (corn and sorghum) are more ef ciency than carbohydrates sources from agriculture by product (rice brand and cassava waste meal), but still pro table use as a source of energy in the ration of sheep.
