Evaluation of perilla seeds (Perilla frutescens) based on nutrient digestibility and pH in vitro tilley and terry

Abstract

Abstract The study was carried out to evaluate the provision of perilla seeds (Perilla frutescens) with the addition of tannins to pH, IVDMD (in vitro dry matter digestibility), and IVOMD (in vitro organic matter digestibility) in the rumen and post rumen. The research used according Completely Randomized Design with four treatments and four replications: T1 = 100% perilla seeds, T2 = 100% perilla seeds + 1% tannin, T3 = 90% basal ration + 10% perilla seeds, T4 = 90% basal ration + 10% perilla seeds + 1% tannin. The method used in vitro two-stage digestibility to the observed of stage I (rumen) and stage II (total). The variables evaluated in this study included IVDMD stage I, IVDMD stage II, IVOMD stage I, IVOMD stage II, and pH. The results showed that giving perilla seeds with the addition of tannin had a pH value obtained in accordance with the pH standard in the rumen (P>0.05); IVDMD stage I and stage II respectively 22.91-35.85% and 36.01-44.15% (P<0.05); IVOMD stage I and stage II were 38.15-48.36% (P<0.05) and 50.04-55.35% (P<0.05), respectively. The conclusion of this research was carried out to give perilla seeds at a level of 10% and 1% tannin in the ration had diverse nutrient digestibility in the rumen and post-rumen. However, it does not affect the pH of the rumen.
