The aim of the study was to test three different hand-milking techniques ("pull down", "thumb in", and "full hand grip") and their effects on milk production and teat treatment. This is important since milk production in many tropical areas still rely on hand-milking. The study was carried out at a peri-urban farm in the Bobo-Dioulasso area in Burkina Faso. Twelve indigenous Zebu cows in early lactation were used in the study. The sequences of the treatments (hand-milking techniques) and the milkers were balanced for carry-over effects between successive periods and days, respectively. The sequences were constructed by using special Latin squares. Yield and composition of saleable milk was not affected by milking technique but there were differences between the milkers in milk yield. There was also a significant interaction for saleable milk yield between milker and milking technique. Hemoglobin in milk was measured as an indicator of teat damage. The hemoglobin content was numerically higher in post-milking strip milk samples than in saleable milk. It was concluded that the amount of milk removed depends mainly on the milker and how well the milking technique works for the individual milker. No effect of milking technique was observed on teat treatment.
该研究的目的是测试三种不同的手工挤奶技术（“下拉式”、“拇指放入式”和“全手握式”）及其对产奶量和乳头处理的影响。这一点很重要，因为许多热带地区的牛奶生产仍依赖手工挤奶。该研究在布基纳法索博博迪乌拉索地区的一个城郊农场进行。研究使用了12头处于泌乳早期的本地泽布牛。处理方式（手工挤奶技术）和挤奶工的顺序分别针对连续时间段和连续天数之间的残留效应进行了平衡。这些顺序是通过使用特殊拉丁方构建的。可售牛奶的产量和成分不受挤奶技术的影响，但不同挤奶工的产奶量存在差异。挤奶工和挤奶技术之间在可售牛奶产量方面也存在显著交互作用。测量牛奶中的血红蛋白作为乳头损伤的指标。挤奶后条带状牛奶样本中的血红蛋白含量在数值上高于可售牛奶中的含量。得出的结论是，挤出的牛奶量主要取决于挤奶工以及挤奶技术对个体挤奶工的适用程度。未观察到挤奶技术对乳头处理有影响。
