Daughter fertility

Improving fertility will therefore shorten the calving interval, increase the lifetime of a cow, lower insemination efforts and reduce veterinary treatments. Since 2010, the calving interval of cows in the Netherlands has been reduced by 10 days to 407 . Fertility is one of the building blocks of CRV Health.

Fertile cows show their heat on time and get pregnant quickly and easily. Good daughter fertility is essential for the continuity of the herd and the farm income.
