Study on Nutritive Value of Tropical Forages in North Sumatra, Indonesia

Abstract

MATERIALS AND METHODS Experimental siteThis study was conducted in Medan (North Sumatra), Indonesia. The province is located in the tropical and monsoon region, and lies between 98-100° East and 1-4° N. There are two seasons during the year, dry season from February to September and rainy season from November to March. The temperature is nearly constant, differing by only a few degrees among the dry and rainy seasons with daily temperature ranges from 18 to 34°C. The annual rainfall ranges from 1,100 to 3,400 mm with humidity varying between 79 to 96%. Collection of forage samplesThe forages evaluated consisted of seven species of grasses (Andropogon gayanus, Axonopus compressus, Brachiaria decumbens, Cynodon plectostachyus, Panicum maximum, Pennisetum purpuphoides and Pennisetum purpureum) and 5 species of legumes (Calopogonium mucunoides, Centrosema pubescens, Gliricidia maculata, Leucaena leucocephala and Pueraria phaseloides). The forage samples were collected during the rainy season

In Vitro Evaluation of Grass and Legume/Browse Species Grazed by West African Dwarf Goats in South-Western Nigeria

“…It has been observed that the legume/browse species contained higher crude protein content than in the grass species. Similar findings were made in the works of Evitayani et al (2004), Babayemi (2007), Ajayi and Babayemi (2008) and Asaolu et al (2014). Also, the crude protein contents of the legume/browse species in the current study were well above the minimum requirement of 11.0 to 13.0% recommended for maintenance and moderate growth of goats (Poppi and McLennan, 1995).…”

“…Thus Ajayi and Babayemi (2008) found out that there were increased proximate composition and in vitro gas production values in the grass/ legume mixtures than sole grass. Other earlier researchers, Evitayani et al (2004) studied the nutritive values of tropical forages commonly used as ruminant feeds in North Sumatra, Indonesia. They observed that crude protein content ranged from 6.6 to 16.2% in grass and from 17.5 to 29.1% in legumes.…”

Production, Competition Indices, and Nutritive Values of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in Mixed Cropping Systems in Peatland

“…These study also showed that CP content of both legumes planted in peatland was generally lower than those found by several researches. Evitayani et al (2004), Omele et al (2011) and Martens et al (2012) reported that CP content of C. pubescen was 18.9%, 25.5%, and 23.6%, respectively. However, Mahala et al (2012), Nasrullah et al (2003) and Heinritz et al (2012) reported that CP content of C. ternatea was 17%, 18.28%, and 19%, respectively.…”

“…Heuzé & Tran (2012) reported that NDF content of S. splendida was 69.5%. Evitayani et al (2004) reported that NDF content of C. pubescens that grows in North Sumatra was 51.1%. Nasrullah et al (2003) found that NDF content of C. ternatea which grows naturally in South Sulawesi was 42.30%.…”

“…Nasrullah et al (2003) found that NDF content of C. ternatea which grows naturally in South Sulawesi was 42.30%. Variation in NDF content is caused by genotype and environmental factors (Adesogan et al, 2002;Nasrullah et al, 2003;Evitayani et al, 2004).…”
