摘要

准确估测反刍动物干物质采食量(DMI)在动物营养学理论和生产实践中具有重要的意义。该领域的研究已经进入建立预测模型并不断完善的时期。动物营养学家提出了多种预测反刍动物DMI的模型,尽管所建立的模型不同,但使用的变量、原理和评价方法是相近的。本文综述了反刍动物采食量的影响因素、调控理论以及DMI预测模型的种类和评价方法,分析了美国(NRC,1996和2001)、英国(AFRC,1993)、法国(INRA,1989)和澳大利亚(CSIRO,2007)等国家提出的DMI预测模型特点,最后提出了探索和完善我国反刍动物DMI预测模型的思路。

Abstract

Accurate estimation of dry matter intake of ruminants is of great significance in theory of animal nutrition and practice. The research in this field has been in the period of building and improving prediction models. A variety of models to predict ruminant dry matter intake were established, which were made by different methods and in different forms but used similar variables, theories and evaluation methods. The paper reviewed the factors impacting ruminant feed intake, feed intake regulation theories, kinds of establishing models and methods for evaluating the models. Ruminant dry matter intake models of United States (NRC, 1996 and 2001), UK (AFRC, 1993), France (INRA, 1989) and Australia (CSIRO, 2007) were briefly analyzed. Finally the way to establish and improve ruminant dry matter intake models in China was suggested.
