奶牛摄食行为学在营养性管理中的有效应用(英文)

Effective Application of Dairy Cow Feeding Behaviorin Nutritional Management

将奶牛摄食行为学应用于奶牛营养性生产管理是提高其临床健康、福利和经济效益的有效方法。首先对奶牛正常行为特征及平均每日行为活动所占时间的分布进行了总结,随后讨论了奶牛饲养中现实条件及管理操作(如:竞争性环境,牛群密度、分组方案等)对其采食行为产生影响;并对利用摄食行为预测围产期疾病的最新研究成果进行了阐述和探讨。相关学者及饲养人员在科研生产中需更有效地利用摄食行为学相关知识,以促进奶牛健康,提高奶牛福利及实际生产效益。建议今后在营养学相关领域的研究能进一步地深入了解奶牛的摄食行为,并加以合理应用,从而满足生产的需要。

Applying dairy cow feeding behavior in nutritional management practice is an effective way of improving cow health, welfare and performance. Normal patterns and daily time budget of dairy cow behavior, then the influence of major management conditions and practices （such as competitive environments, stocking density, grouping strategies） on cow＇s feeding behavior was discussed. Finally, new findings of using feeding behavior to predict disorders in transition period were addressed. It was suggested that dairy researchers and farmers should take advantage of related knowledge of dairy cow feeding behavior to improve cow health, welfare and profitability. More research in nutrition-related fields is required to further study dairy cow feeding behavior so as to better apply it in nutritional management and meet the needs of production.
