| 不同地区优势混合牧草营养成分比较
摘要
牧草作为不可或缺的生产资料，是内蒙古自治区草原畜牧业的基础。本研究所使用的实验材料采用锡林郭勒盟的不同地区的优势牧草进行混合，包括羊草、贝加尔针茅、线叶菊和白茅。测定混合牧草粗灰分、粗蛋白、钙、磷、中性洗涤纤维、酸性洗涤纤维、半纤维素、纤维素、木质素等含量，实验结果表明混合牧草1的采食量和降解率较高、混合牧草4的蛋白含量较高。
畜牧业是内蒙古自治区传统支柱产业，饲草饲料是畜牧业发展的基础,市场发展前景巨大。比较不同地区优势混合牧草常规营养成分含量的差异，不仅有助于加快牧草饲料业的发展，还能发展区域经济、改善生态环境。鉴于此,文章以此为出发点,对不同地区优势混合牧草予以归纳探究,探寻些许可循新路径,仅供参考和借鉴。

Abstract
Forage, as an indispensable means of production,is the basis of grassland animal husbandry in Inner Mongolia Autonomous Region. The experimental materials used in this study were mixed with dominant forages from different regions of Xilin Gol League,including Leymus chinensis, Stipa baikal, Asteria chinensis and Whitelgrass. The content of ash, crude protein, calcium, phosphorus, neutral detergent fiber,acid detergent fiber, hemicellulose, cellulose and lignin of mixed herbage was determined. The results showed that the feed intake and degradation rate of mixed herbage1 were higher, and the protein content of mixed herbage 4 was higher.
Animal husbandry is the traditional pillar industry of Inner Mongolia Autonomous Region.Forage forage is the foundation of animal husbandry development, and the market development prospect is huge. Comparing the differences of conventional nutrient contents of dominant mixed forage in different regions will not only help to accelerate the development of forage and feedindustry, but also help to develop regional economy and improve ecological environment. In view of this, this paper takes this as a starting point to summarize and explore the superior mixed herbage in different regions, to explore some new paths to follow, for reference only.
