Abstract. This study aimed to determine the pattern of body weight gain and vital statistical measures of fat sheep and thin tails and to determine the response of local sheep production to the provision of soybean meal/skin. The method used in this research is a case study and experimental. The sampling technique is done by a simple random method on vital statistical measures performed by measuring the chest (using a measuring tape) and body length (usingmeasuring stick). The tabulated data were first analyzed for homogeneity and normality, which were then tested by an independent sample t-test using SPSS. As for the growth response, the material used was 16 male FTS and TTS aged under one year. Daily body weight growth between Fat tail Sheep (FTS) and Thin Tail Sheep (TTS) showed very significant differences (P <0.01). Statistical analysis showed that body length between FTS and TTS had no difference (P> 0.05), chest circumference between FTS, and TTS; there was no difference (P>0.05). Adding bodyweight FTS and TTS were respectively 93.29 ± 26.73 g / head / day and 78.18 ± 27.01 g / head / day. The FTS and TTS bodies’ length was 49.81 ± 4.06 cm and 49.34 ± 4.80 cm, respectively, while the chest circumference between FTS and TTS was 63.61 ± 3.98 cm and 62, respectively. 17 ± 4.10 cm. The daily body weight gain of rams fed with additional soybean husk feed statistically results obtained significant differences (P <0.05), the results of the study showed that the Daily Weight Gain (DWG) FTS male respectively P0, P1, P2, and P3 groups respectively namely: 105.07 ± 3.58; 118.08 ± 2.65; 140.38 ± 4.40; 155.01 ± 4.01 ghead/day. The results showed that the feed efficiency of male rams in each group P0, P1, P2, and P3 were: 7.84 ± 0.27; 8.25 ± 0.18; 9.27 ± 0.29; and 9.75 ± 0.32%. While for TTS also obtained a significant difference (P <0.05) DWG at P0, P1, P2, P3 is 101.02 ± 2.18; 116.9 ± 2.88; 127.82 ± 3.20; 140.31 ± 2.41 g / head / day, so that the efficiency of feed obtained for TTS is P0, P1, P2, P3 respectively 6 ± 0.19; 7.14 ± 0.11; 8.87 ± 0.22; 9.85 ± 0.12. It was concluded that the provision of soybean meal had a significant positive effect on growth and vital statistics, both for sheep with fat tails and thin tails.
