Determination Nutritional Value and Digestibility of Three Rangeland Plants of Through Chemical Method and in Situ (Nylon Bags) Techniques
並列摘要
This research has been conducted to evaluate nutritional value, digestibility and degradability of three rangeland species ＂Dactylic glomereta＂, ＂Onobrychis sativa＂ and ＂Setaria galauca＂ through chemical and in situ methods. The experiment conducted based on Randomized Complete Design with three fistulated sheep in 3 replications and obtained data were analyzed by software SAS and Neway. Specifications such as Crude Protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Ether Extract (EE), Ash, Crude Fiber (CF), NFC (Non Fiber Carbohydrate), Nitrogen Free Extract (NFE) and organic material (OM) were determined in chemical method and degradation of dry matter and protein were determined at times 0, 4, 8, 16, 24, 48, 72 and 96 through in situ method for the three species. ＂O. sativa＂ showed the most amount of crude protein (23.95%) and the least amount of ADF. Also, ＂S. galauca＂ showed the least amount of protein (7.95%) and the most amount of ADF (45.73%). Results of degradability in in-situ (nylon bags) method show that ＂S. galauca＂ has the least and ＂O. sativa＂ has the most degradability of dry matter and protein. Results also show that ＂O. sativa＂ and ＂D. glomereta＂ have the capability of being applied as livestock food and ＂S. galauca＂ could be applied aslivestock food in combination with suitable species of legumes.
