An unselected material consisting of composite milk samples from 1029 Ayrshire and 113 Friesian cows were analysed for the β-lactoglobulin types. The frequencies of β-Lg types were AA 8.3 %, AB 45.5% and BB 46.3 % for Ayrshire cows and 22.1 %, 45.1 % and 32.8 for Friesian cows, respectively. The relationship between β-Lg type with milk BSA, somatic cell count, protein percentage, fat percentage and milk production were analysed. AA cows were significantly higher in daily milk yield but lower in protein percentage and fat percentage than BB cows; AB types were intermediate. The annual production was highest in AB-animals. There was a tendency for AA cows to have high somatic cell counts but low milk BSA concentrations. β-lactoglobulins; milk BSA; somatic cell count; bovine mastitis; bovine milk; milk proteins.
对从1029头艾尔夏奶牛和113头弗里生奶牛采集的复合乳样组成的未选择材料进行了β-乳球蛋白类型分析。艾尔夏奶牛的β-Lg类型频率分别为AA型8.3%、AB型45.5%和BB型46.3%，弗里生奶牛的频率分别为22.1%、45.1%和32.8%。分析了β-Lg类型与乳牛血清白蛋白、体细胞计数、蛋白质百分比、脂肪百分比和产奶量之间的关系。AA型奶牛的日产奶量显著高于BB型奶牛，但蛋白质百分比和脂肪百分比低于BB型奶牛；AB型处于中间水平。AB型动物的年产量最高。AA型奶牛有体细胞计数高但乳牛血清白蛋白浓度低的趋势。β-乳球蛋白；乳牛血清白蛋白；体细胞计数；牛乳腺炎；牛乳；乳蛋白。
