Replication Data for \"Different protein sources in concentrate feed to dairy cows affects cheese making properties and yield\"

Norwegian Red dairy cows (n = 48) in early/mid lactation were divided in three groups and fed a ration consisting of grass silage and concentrate, where the concentrates were barley based but with different additional protein sources. These were: completely barley-based with no additional protein source (BAR), additional protein from soybean meal (SMB) or additional protein from yeast (Cyberlindnera jadinii) (YEA). The SBM and YEA concentrates had a higher protein content than the barley concentrate. Four batches of cheese were made from pooled milk from each of the three groups of dairy cows and individual milk samples were collected five times during the experiment and were analysed.

选取48头处于泌乳早中期的挪威红奶牛（Norwegian Red dairy cows），将其分为三组，饲喂由青贮牧草（grass silage）与精料（concentrate）组成的日粮。各组精料均以大麦为基础，但添加的额外蛋白质源有所不同：分别为完全以大麦为基础且未添加额外蛋白质的对照组（BAR）、以豆粕（soybean meal）作为额外蛋白质源的组（SMB），以及以赛伯林德纳酵母（Cyberlindnera jadinii）作为额外蛋白质源的组（YEA）。其中SMB组与YEA组的精料蛋白质含量均高于纯大麦精料。研究人员以三组奶牛的混合乳为原料制作了四批次奶酪，并在实验期间五次采集个体乳样进行分析检测。
