Abstract
The purpose of this research was to determine the influence of Myristic acid and the source of condensed tannin on corn straw basedcomplete 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
Highlights
Corn is a type of agricultural crop whose main results are utilized by humans, while byproducts include corn straw, cob, corn seeds that can be used as animal feed [1]
Based on the results of the analysis showed that the addition of myristic acid and calliandra leaf meal (Calliandra calothyrsus) as a source of tannin content in corn straw-based complete feed (Zea mays) gave a significant difference (p
The use of calliandra leaf meal and the addition of myristic acid to complete feed based on corn straw can increase the value of dry matter degradation (DMD) and organic matter degradation (OMD)
Summary
Corn is a type of agricultural crop whose main results are utilized by humans, while byproducts include corn straw, cob, corn seeds that can be used as animal feed [1]. The productivity of corn crops every year has increased significantly. National corn production in 2014 was 19.0 million tons. The increase in corn production continued to grow in 2016, which was 23.6 tons, in 2017, it reached 28.9 million tons, and in 2018, there was a significant increase of 30 million tons. In Indonesia, corn straw frequently becomes one of the feed compositions in complete feed. The complete feed consists of a mixture of forages and concentrates high in nutrients with a balanced ratio and arranged according to livestock needs [8]
