Abstract: | 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. |
