There are several examples of cows whose peak production is 30 liters and above during the 1st lactation period, which increases to 45 liters and above during the 2nd lactation period. The increase in milk depends upon the dry period; if the dry period is up to 3 months, the milk increase is greater than if the dry period is below 1 month.

In imported Friesian cow’s milk increase from the first lactation to fourth lactation is approximately 50%, whereas in crossbred cows the milk increase is approximately 100% from first to fourth lactation. Similarly, the milk increase is greater in cross-bred cows over the generations as compared to pure-bred cows. Pakistani cross-bred cows are more adaptable to the environment and less prone to diseases.
