Research Advances in Prediction Models of Dry Matter Intake in Ruminants
摘要
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.关键词
