Sources of variation in the milk flow rate and its relationships with milk yield, milk composition, age and stage of lactation in dairy cows



Sources of variation in the milk flow rate and its relationships with milk yield, milk composition, age and stage of lactation in dairy cows



British Veterinary Journal 132(1): 90-94



Average milk flow rate and milk yield of 12 lactating cows were recorded at Friday and Tuesday afternoon milking and Saturday and Wednesday morning milking each wk for 2 wk. Animal variations were significant at the 1% level for milk flow rate, milk yield, milk fat and milk protein percentages. There were significant differences in the morning and afternoon milk flow rates, milk yield, and milk fat percentages. Milk flow rate was positively correlated with milk yield, and negatively correlated with age and somatic cells in the milk. Milk yield was negatively correlated with the somatic cells.
