摘要
选用3~4胎,产仔数8~13头的8头健康内蒙黑猪母猪,对其分娩后5d内初乳化学成分的变化规律进行了研究。结果表明,初乳中干物质、蛋白质、脂肪、乳糖、Ca、Mg、Cu、Fe、IgG的含量以及pH值均在产后24h内变化极显著(P<0.01),3d后趋于平稳,到第5d接近常乳(P>0.05)。
Colosdtral sample was collected from 8 clinically normal 3-4year-old Inner Mongolia Black Sows that had farrowed litters containing 9-13 live piglets,within 5days of postartum period and conventional ingredients of colostum were analyzed. The results indicated that the Changes of DM, Protein, Fat, Lactose, Ca, Mg, Cu, Fe, IgG and pH value in colostrum were significant(p<0.01) within24h postpartum.Their change become constant at 3rd day and proximate to milk at 5th day (p>0.05)
