Effectiveness of Supplementation of Soybean Oil (CaS Soybean) in Local Feed-Based Concentrate on Etawa Crossbred Goat Productivity

Abstract This study aims to evaluate the effectiveness of soybean oil supplementation in concentrate on the productivity of Ettawa crossbreed (EC) goats. This study used 4 lactating local Ettawa crossbreed goats from Southeast Sulawesi weighing 24-33 kg. This study used a Latin square design (RBSL) with 4 treatments and 4 replications. The treatments consisted of T1 (40% green fodder and 60% concentrate without containing CaS-Soybeans), T2 (60% green fodder and 40% concentrate containing 2.5% CaS-Soybeans), T3 (50% green fodder + 50% concentrate containing 5% CaS-soybeans), T4 (40% green fodder and 60% concentrate containing 7.5% CaS-soybeans). The parameters observed included: feed nutrient consumption, milk component production, and goat milk production efficiency. This research uses ethical clearance number: 216/UN29.20/EC/2024. The data obtained were analyzed using the compare means-oneway Anova analysis, and for treatments that had a significant effect, the Duncan test was continued. The results showed that supplementation of CaS-Soybean in local feed-based concentrate had a significant effect (P<0.01) on DMI, OMI, milk production, and milk components. This study concludes that supplementation of CaS-Soybean up to 7.5% can be used in goat feed concentrate.
