Evaluation on Feeding Value of Ramie Using in Vitro Gas Production and Nylon Bag Methods
摘要
Abstract
In this experiment, the feeding value of ramie leaf, ramie whole plant and ramie whole plant without fiber were evaluated by in vitro gas production and nylon bag methods.The ramie leaf, ramie whole plant and ramie whole plant without fiber were used to determine 72 h dynamic gas production by in vitro gas production method, and then gas production parameters were calculated;the above three materials were applied to measure degradation rates of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) using nylon bag method, and then degradation parameters were determined.The results showed as follows : 1) in the experiment of in vitro gas production, 72 h gas production and theological maximum gas production of ramie whole plant were the highest, and were significantly higher than those of ramie whole plant without fiber (P<0.05);the values of ramie leaf were in the middle, and had no significant difference with those of the other two materials (P>0.05).2) In the experiment of nylon bag, 72 h degradation rates of DM, CP, NDF and ADF showed ramie leaf>ramie whole plant>ramie whole plant without fiber;and the effectively degradation rates of DM, NDF and ADF showed the same tendency;however, when it came to effectively degradation rate of CP, ramie whole plant>ramie leaf>ramie whole plant without fiber.Considered from in vitro gas production and effectively degradation rate, feeding values of ramie leaf and ramie whole plant are superior to that of ramie whole plant without fiber.[Chinese Journal of Animal Nutrition, 2017, 29关键词
