Effect of The Combination of Protected and Non-Protected Soybean Oil (Glycine max L.) Supplementation on Characteristics of Rumen Fermentation, Nutrient Digestibility, and Nitrogen Balance in Garut Sheep

Soybean oil is a high source of unsaturated fatty acids which if given to sheep have the potential accumulate in meat. However, rumen undergoes biohydrogenation by microbes, and addition fat feed has reduce fiber fermentation can an impact on animal performance. This study aimed determine effect combination protected non-protected soybean supplementation characteristics fermentation, nutrient digestibility, nitrogen balance Garut sheep. Twelve male lambs aged 13 months weighing 29±3.23 kg were kept metabolic cage divided into three groups. The basal diet 60% King grass 40% pollard bran was supplemented with ratio 3%:0%, 1.5%:1.5%, 0%:3%, respectively, based dry matter ration. data obtained analyzed One-Way ANOVA, followed Duncan Multiple Range Test (DMRT). results showed that had no profile, microbial protein, ammonia concentration, total volatile acids, acetat, propionate, butirat, pH. digestibilities matter, organic crude fibre, not affected. Supplementation also balance. Hence different levels fats did influence performance
