In-vitro nutrient degradability of complete feed containing myristic acid and tannins addition

Abstract

The purpose of this research was to determine the influence of Myristic acid and the source of condensed tannin on corn straw based-complete feed on nutrient content and in vitro digestibility. The method which was used in this experiment was randomized block design with four treatments and three replications. The treatment consisted of T0 complete feed (40% corn straw + 60% concentrate), T1 complete feed (40% corn straw + 60% concentrate + myristic acid 30 g/Kg DM), T2 complete feed (40% corn straw + 50% concentrate + calliandra leaf meal 10%/Kg DM and myristic acid 30 g/Kg DM), T3 complete feed (40% corn straw + 45% concentrate + calliandra leaf meal 15%/ Kg DM and myristic acid 30 g/Kg DM), T4 (40% corn straw + 40% concentrate + calliandra leaf meal 20%/Kg DM and myristic acid 30 g/Kg DM). Based on the result, it could be concluded that calliandra leaf meal 15%/Kg DM + Myristic acid 30 g/Kg DM on the complete feed (T3) was the best treatment based on nutrient content and increase of dry matter digestibility, but not an effect of organic matter digestibility.
