Nutritional parameters of grazing nursing calves 1:rumen microbial production

摘要：

Brazil has the largest commercial cattle herd in the world.Approximately 95％ of the meat production in the country came from animals on pasture.In spite of this,little has been studied about the effects of the interaction between pasture conditions,animal life phase and fed supplement.Protein supplementation has been widely used because it potential to improve the pasture digestibility.Finally,although the milking phase is responsible for up to 50％ of the final weight of beef cattle,it has been little studied.The objective of this study was to evaluate the response of ruminal microbial production in nursing calves receiving different protein levels supplement under Brazilian autumn conditions.
