<![CDATA[This study aimed to determine the effect of using complete feed containing protected soybean groats on the production performance and feed efficiency of fattening thin-tailed sheep. Protection using 37% formaldehyde as much as 1% of dry soybean groats to bypass protein during rumen fermentation. A total of 15 male thin-tailed sheep, aged 12 months with an initial body weight of 23.43±1.40 kg were divided into 3 groups of feed treatments, namely the first group (P1) complete feed 100%, (P2) complete feed 90% + protected soybean groats 10%, and (P3) complete feed 80% + protected soybean groats 20%. Protection of soybean groats using 37% formaldehyde was given as 1% dry matter. The research design used a Completely Randomized Design (CRD). Data were analyzed using analysis of variance, and differences between treatments were further tested with Duncan's Multiple Range Test. The results showed a significantly different effect (P<0.001) on dry matter consumption but not significantly different (P>0.05) on daily body weight gain, relative daily body weight gain, feed conversion, and feed efficiency. The conclusion of the research was that the use of complete feed containing 20% protected soybean groats was efficient due to its ablity to increase dry matter consumption and the FCG produced was low so that higher IOFC was obtained.]]>
