Effect of emulsified high-PUFA oils enriched with natural antioxidants on in vitro goat rumen fermentation parameters and nutrient degradability

This study aims to evaluate the effect of emulsified high-PUFA oil enriched with natural antioxidants derived from jackfruit leaf extract on in vitro goat rumen fermentability and degradability. The study used a completely randomized design with two treatments and 5 replications. The treatments were supplementation with high-PUFA oil + natural antioxidants separately (P1, as the control), and supplementation with emulsified high-PUFA oil + natural antioxidants (P2). The parameters observed were rumen pH, total volatile fatty acid (VFA) concentration, NH₃ concentration, bacterial population, protozoa population, dry matter digestibility (DMD), and organic matter digestibility (OMD). The results showed that supplementing goat feed ration with emulsified high-PUFA oil enriched with natural antioxidants did not alter (P>0.05) rumen pH, total VFA, NH3 concentration, bacterial and protozoal population, DMD, or OMD. Overall, emulsified high-PUFA oil with natural antioxidants did not alter the examined rumen fermentation parameters and degradability. Thus, emulsified high-PUFA oil with natural antioxidants can be potentially used as an effective feed supplement to support goats' performance.
