粗饲料营养价值指数及评定方法

Roughage nutritional value evaluation indices and research methods

粗饲料是反刍动物瘤胃微生物和宿主主要的营养来源,科学有效地评价粗饲料营养和饲喂价值,对于开发饲料资源、合理利用粗饲料和提高其利用效率至关重要。本文简述了国内外对动物粗饲料营养价值的评定指数和方法,介绍了粗饲料营养价值评定方法的发展以及各方法的优缺点,指出实际研究中可根据不同的科研需求,选择适合的评定指数和方法,根据实际情况完善评定指数和评定方法,对粗饲料营养价值的科学评定和合理利用起到一定借鉴作用。

Roughage is the main source of nutrition for rumen microbes and their hosts.It is essential to effectively and scientifically evaluate roughage nutrition and feed value,to develop feed resources,to understand reasonable use of roughage,and to improve its utilization efficiency.This review of a large number of domestic and foreign studies details the evaluation indices and methods of evaluating the nutritional value of crude feed.It also discusses the development of evaluation methods and the advantages and disadvantages of each method.We can select the best evaluation index and method according to research needs,but this selection can play a role in the evaluation and rational utilization of the nutritional values of crude feed.
