摘要
奶牛酮病是由于体内代谢紊乱所引起的一种代谢性疾病,主要表现为产奶量、乳汁质量下降,繁殖性能降低,以及内分泌紊乱等,导致奶牛淘汰率增加,给奶牛场造成严重的经济损失。近年来,奶牛酮病的发生率有呈上升的趋势,与目前奶牛产奶量高、日粮结构改变有很大的关系。通过营养调控在一定程度上可以降低酮病的发生率。
Dairy cow ketosis is a metabolic disorder or syndrome, which is not secondary to any other recognized disease. The major characteristics of ketosis include decreased milk yield, low milk quality, low reproductive performance, and endocrine disorder in dairy cows, which increase culling rate of dairy cows. So these lead to serious economic loss in cow farm. Recently Dairy cow ketosis tends to increase, which is associated with high production and the changes of diets of dairy cow. Studies indicated that manipulating nutrition supply can decrease Dairy cow ketosis.
