Effort and time in pipeline milking.

Abstract

Effort and time spent in machine milking using pipeline vs. bucket milking methods were compared in a conventional cowshed and in a 2-level milking parlour. In each case 2 units were used and cows were machine-stripped. In the cowshed data were obtained for each of 6 milkers milking 20 low-yielding cows; in the parlour each of 3 milkers milked 21 moderate yielding cows. Total energy expenditure (measured at one milking only for each of the cowshed milkers) averaged 5.0 kcal./min., but considerable variation was shown between workers. In the cowshed mean heart rate was similar for the 2 milking methods but in the parlour heart rates were higher for bucket than pipeline milking; the former also involved greater increase in effort in carrying the filled cans and in cleaning the milking equipment. Milking time for the bucket method exceeded that for the pipeline method by 18% and 9% in cowshed and parlour respectively. Practical aspects are discussed. R.B.S.
