Nutritional value of ramie and it sruminal degradability
摘要
Abstract
The aim of this study was to investigate the nutrient components and ruminal degradability character-istics of ramie.Common nutrition components,amino acids composition,and anti-nutrient (e.g.,tannin) contents were determined for seven ramie samples containing different proportions of stubble,and the ruminal degradability was estimated using three male Boer goats fitted with permanent rumen fistula.The average crude protein (CP)content of the seven stubble samples was 19.57%.The CP content decreased with increas-ing proportions of stubble,but the CP content in sample 7 ,which had the highest proportion of stubble,was slightly higher than that in sample 6 ,which had a slightly lower proportion of stubble.The average total amino acids content was 16.40%,accounting for 83.80% of CP.The average Lys and Thr contents were 0.84% and 0.82%,respectively.The average content of tannin,the main anti-nutrient in ramie,was 0.67%.The rumi-nal degradability of ramie dry matter,CP,organic matter,neutral detergent fiber,and acid detergent fiber in-creased with longer digestion time;the effective degradability of these nutrients was 47.00%,35.53%, 44.29%,57.68% and 38.59%,respectively.In conclusion,ramie has a high protein content,high-quality CP,and high rumianl degradability of some nutrients.Therefore,it is a good forage for ruminants.关键词
