酵母培养物在反刍动物高精料饲粮条件下的应用研究进展
Research Advances in Application of Yeast Culture in High?Concentration Diets of Ruminants
摘要
Abstract
Under intensification production system, nutrition strategy using high level of concentrate is provided to high lactating dairy cows, fattening beef cattle, and meat sheep for high performance. Long?term feeding a high content of concentrate or a large amount of carbohydrate in a short time would cause metabolic disorder in the rumen, resulting metabolic ruminal acidosis and diarrhea and other diseases. Therefore, it is a key question to make nutrition regulation to achieve rumen health when high level of concentrate is offered to animals. As one type of microecological preparation, yeast culture has been widely studied and used in ruminant production system, playing an important role in keeping rumen health, enhancing performance and immunity function. This paper reviewed the function mechanism and application effect of yeast culture under high?concentrate di?ets, and discussed the appropriate addition level, aiming to provide application reference and theoretical basis for the utilization of yeast culture in the ruminant production.[ Chinese Journal of Animal Nutrition, 2019, 31 (8) :3473?3481]关键词
