Application single-cell protein in ruminant feed has a purpose to fattening, which one of parameter to measure is average daily gain (ADG). The name of single-cell protein in this research is ajitein. The research aimed to evaluate the nutritive value of ajitein toward feed consumption, average daily gain and feed conversion in fat-tailed sheep. In this research, ajitein was mixed with other feedstuffs (soybean meal, pollard, coconut cake, corn bran, palm cake, molasses, urea, and minerals) and the crude protein in this concentrate was isoprotein (22%). The treatments in this research consist of P0: elephant grass (ad libitum) with concentrate; P1 : elephant grass (ad libitum) with concentrate (ajitein 2%); P2 : elephant grass (ad libitum) with concentrate (ajitein 4%); P3 : elephant grass (ad libitum) with concentrate (ajitein 6%). The result showed that the highest feed intake in this research was P0 (104.9 ± 12.90 g / kg BB0.75 / day). Then the higher body weight gains are P0 and P3, with 140 g/head/day respectively. The feed conversion of P3 was 6.6 ± 0.87. The conclusion was P3 had good ability to change the feed to be meat more effective.
