摘要
呼和浩特市土默特左旗秸秆资源极其丰富,但利用率非常低,大部分被粉碎还田或者焚烧,造成严重的资源浪费和环境污染。近年来,随着牛奶价格不断下跌,奶牛场着眼于降低饲养成本,玉米秸秆逐渐被人们重视,但大规模的玉米秸秆加工问题没能得到妥善解决。为此,在总结前人研究基础上结合当地生产现状,奶联社引进切碎圆捆机对玉米秸秆进行切碎打捆,使其成为后备牛及肥胖干奶牛良好的粗饲料来源,在降低饲喂成本的同时明显改善了奶牛体况。
Resources of maize stover have extremely rich in Hohhot Tumotezuoqi, but the utilization is very low, the most were crushed or burned to field and causing serious environmental pollution and waste of resources. In recent years, with the milk prices falling, majority of dairy farms reduce the feed costs, and gradually pay attention to the corn stalks, but corn stover production and post-natal problems could not be properly resolved. To this end, on the basis of previous studies combined with the status of local production, milk association has introduced the chopped round baler for baling corn stalks, not only an effective solution to the problem of production and post-natal, but also making it be the source of roughage for heifers and obesity nonlactation cows. Reducing the feeding costs significantly could simultaneously improve the body condition of cows.
