Extract

1. The influence of the age of cows on the milk yield and on the milk solids is traced. The milk yield reaches a maximum at about the sixth lactation and then declines. The concentration of fat and solids-not-fat shows a gradual decline from the first lactation onwards.

2. During lactations in which the yield is below the normal productivity of a cow, the quality of the milk also tends to be subnormal.
