为了研究蛋氨酸铬对母猪乳成分、泌乳相关激素和免疫指标的影响，选取18头健康杜洛克×长白母猪随机分为2组，即对照组（基础日粮）和试验组（基础日粮中添加5 g/t蛋氨酸铬）,试验于产前7 d开始至产后21 d结束，在产后1、11、21 d采集母猪乳样，检测乳中乳糖、蛋白质、灰分、非脂固形物、脂肪的含量和乳的密度，胰岛素（INS）和催乳素（PRL）等泌乳相关激素的含量和免疫球蛋白A（IgA）、免疫球蛋白G（IgG）和免疫球蛋白M（IgM）等免疫指标的含量。结果显示，与对照组相比，产后1、11 d试验组乳中各乳成分指标差异均不显著（P＞0.05）,产后21 d试验组乳中乳糖、非脂固形物、蛋白质和脂肪的含量显...

In order to study the effects of chromium methionine on milk composition,lactation related hor-mones and immune indexes of lactating sows,eighteen healthy Duroc×landrace binary sows were random-ly divided into two groups(control group and experimental group).The control group was fed the basal di-et,and the experimental group was fed the basal diet supplemented with 5 g chromium methionine/t.The experiment began from the 7th day before delivery to the 21st day after delivery.Milk samples of sows were collected on the 1st,11th and 21st day afte...
