Abstract

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

Abstract

The goal of this study was to ascertain the impact of soybean meal's temperature and heating duration as undegraded protein (UDP) on Bali cattle's dry matter (DM) and organic matter (OM) degradation kinetics. Soybean meal is a feed ingredient with high protein content, which is about 48%, and is rapidly degraded in the rumen. In this investigation, a  factorial design was employed with the first factor being temperature (60, 80, 100, and 120°C), and the second factor being heating time (10, 20, 30, and 40 min). Protected soybean meal was tested for degradation using the in sacco technique on the rumen of fistulous Bali cattle. A sample of 5.0 g was put into a nylon bag and then for 0, 2, 4, 8, 16, 24, and 48 h in the rumen, then analyzed for feed residues for DM and OM. The results showed that soybean meal protected by the heating method could reduce the degradation of DM and OM in the rumen (p<0.05). Heating at 120°C for 40 min showed the lowest DM and OM degradations in this study.
