Abstract
This study was conducted to determine the effect of feeding protected and unprotected soybean groats with different ratios on production and carcass quality of male thin-tailed sheep (TTS). The TTS were fattened for 3 months with an average initial weight of 24.09 ± 1.26 kg. Treatments consist of P1=protected and unprotected soybean groats 10%:5%, P2=protected and unprotected soybean groats 7.5%:7.5% and P3=protected and unprotected soybean groats 5%:10%. Data were analysed using a completely randomized design with three treatments and three replications. The variables observed in this study were the slaughter weight, percentage (carcass, non-carcass, meat, fat), fleshing index, rib eye muscle (longissimus dorsi) area, and meat bone ratio. This study displayed significant improvement from treatment using 10% protected + 5% unprotected soybean groats (P1), having the highest meat and fat percentage, as well as meat bone ratio. Inclusion of protected soybean groats in the diet up to 10% level had limited effect (P>0.05) on slaughter weight, carcass percentage, non-carcass percentage, fleshing index, and rib eye muscle area. This study suggests the combination of soybean groats in the diet in the form of protected:unprotected (10%:5%) provide significant improvement on carcass characteristics, while maintaining quality of carcass in the thin-tailed sheep. Further study on meat quality attributes from these supplementations requires deeper exploration.
