376. Experiments on milking technique: 3. Combined effect of reducing the milking time and washing the udder with hot water: 4. Effect of increasing the milking time

Abstract

1. An experiment is reported in which the influence of washing the udder with hot and cold water and of reducing the milking time to 60% of the normal flow period (interval between putting on teat cups till main flow ceased) was studied over a period of 9 weeks in twenty cows.2. The temperature of the udder washing water had no measurable effect on output of milk or speed of milking. The reduction in milking time failed to increase rate of milk flow and resulted in a fall in milk yield.3. An experiment with ten cows is reported in which the teat cups were, for periods of 6 weeks, left on at each milking twice as long as was necessary to carry out a normal milking.Neither the yield and quality of milk nor the rate of milking were affected.
