Abstract

Taiwan Napier (Pennisetum purpureum) is a perennial forage crop with good nutritive value, high productivity, and growth rate and currently used for cutting and carry system over the tropical and sub-tropical area of the world. The aim of this study is to evaluate the chemical composition content in different growth stages of Taiwan Napier. The different harvesting days of growth stages were 15, 30, 45, 60, 75 and 90 days. The plant's samples were collected at Ladang Kongsi 1, Pasture Unit (TPU), Universiti Putra Malaysia Bintulu Sarawak Campus. This study was analyzed using proximate analysis methods ie dry matter, moisture, crude protein (CP), crude fibre (CF), ether extract (EE), and acid detergent fibre (ADF). Results showed that it has a significant effect at different growth stages on the percentages in leaves and stems content for all parameters that have been measured in Napier grass. The percentage of dry matter increased as the days increased, respectively. The moisture content, crude protein stems, and both crude fats decreased when days increased. Crude fibre amount in leaves and stems were highest at days 60 (36.50±1.80%) and days 90 (40.33±0.76%), while lowest amount at days 15 (28.17±1.04%) and (29.67±1.61 %). For crude protein leaves, both part ash and ADP result were increased from early to intermediate and then decreased at maturity stages. The different harvesting days after given an effect on the chemical compositions of Napier grass. Hence, the best Napier grass can be harvesting is within two months of the cutting period which is providing the high nutritive amount of the animal fodder.
