围产期奶牛血清糖、脂代谢变化的研究
发布时间：2018-10-17 11:31
【摘要】：正围产期包括干奶后期(产前2~3周)和泌乳初期(产后2~3周),奶牛从妊娠转入泌乳阶段。奶牛在围产期会出现许多生理特性变化,主要表现为产犊前后营养需求和代谢的不同。在产后1周奶牛会大量消耗自身储存的能源物质,出现能量负平衡。因此,本试验通过检测围产期奶牛血清中糖及脂代谢的变化情况,从中探寻规律,对围产期奶牛的营养代谢病(如脂肪肝、酮病及低钙血症)的预防和预测提供一
[Abstract]:The positive perinatal period includes the late period of dry milk (2 weeks before birth) and the early stage of lactation (2 weeks after delivery), and the cow transfers from pregnancy to lactation stage. During perinatal period, there are many changes in physiological characteristics of dairy cows, mainly manifested by the difference of nutrition requirement and metabolism before and after calving. During the first week after delivery, cows consume a large amount of energy materials stored in their own reserves, resulting in negative energy balance. Therefore, by detecting the changes of glucose and lipid metabolism in serum of perinatal cows, this experiment aims to explore the rules for the prevention and prediction of nutritional metabolic diseases (such as fatty liver, ketosis and hypocalcemia) in perinatal cows.
