摘要
葡萄糖是提供给动物代谢活动快速应变需能的最有效营养素,是机体各组织代谢的主要能源。葡萄糖供应不足时,奶牛易患酮症,而过瘤胃技术可以使营养物质在瘤胃中的降解率降低,并使其在小肠的消化和吸收增加,从而使营养物质的消化利用率得到提高。经过瘤胃技术处理后的葡萄糖,可使奶牛生产中对葡萄糖的利用率得到提高,文章就过瘤胃葡萄糖在泌乳奶牛生产中的应用作以综述。
Glucose is one of the most effective nutrients for the rapid response to the metabolic activity of animals, and it is the main source of energy for the body＇s metabolism. When glucose is insufficient, cows will have a predisposition to ketosis. The rumen bypass technology can reduce nutrient degradability in the rumen, and increase their digestion and absorption in the small intestine, thereby improve the digestibility of nutrients. Glucose by rumen technical processing can improve their utilization in dairy cattle production. This article reviewed the effect of rumen bypass glucose on production performance of lactating dairy cows.
