A study was carried out to evaluate the effects of an automatic milking system (AMS) on milk yield and composition of buffalo (Mediterranean-type Bubalus bubalis) cows. Performed from January 2015 to December 2015 in an organic buffalo dairy farm equipped with both a traditional tandem milking parlor and an AMS, the study involved 90 primiparous buffaloes randomly allotted to a tandem or AMS group from 5 to 10 d of lactation onward. Number of milkings per day and daily milk yield of each cow were recorded, and individual milk sampling was carried out twice a month. Compared with the tandem, the AMS group showed significantly higher daily milk yield and persistence of lactation. Use of the AMS resulted in higher protein and casein contents, and lower somatic cell and total bacterial counts, whereas fat, freezing point, and pH were unaffected by the system. We conclude that, in terms of milk yield and quality, automatic milking may be a suitable alternative to conventional milking for buffaloes.
一项研究评估了自动化挤奶系统（AMS）对奶产量和组成对水牛（地中海型布氏 Bubalus bubalis）奶牛的影响。该研究于 2015 年 1 月至 12 月在一个配备传统串联式挤奶厅和 AMS 的有机水牛奶牛场进行，涉及 90 头初产水牛，从产奶后 5 至 10 天开始，随机分配到串联或 AMS 组。记录了每天的挤奶次数和每头奶牛的日产奶量，并每月进行两次个体牛奶采样。与串联式相比，AMS 组的日产奶量和泌乳持续时间显著更高。使用 AMS 会导致蛋白质和酪蛋白含量增加，体细胞和总细菌计数降低，而脂肪、冰点和 pH 值不受系统影响。我们得出结论，就产奶量和质量而言，自动挤奶可能是水牛传统挤奶的一种合适替代方式。
