Scientists from the University of Florida have reached a striking research result that examines in depth the effects of the calving season on the lifespan and productivity of dairy cows. The research revealed that cows born in the summer months are sold earlier due to health problems, while cows born in the cool winter months remain productive for a longer period. This finding has the potential to be an important guide for both farmers and the livestock sector.

In a comprehensive examination of more than 19 thousand Holstein cows, it was determined that cows born in the winter season have longer lifespans and remain in the herd for 5 or more lactation periods. It was observed that these cows can maintain their productivity for a long time and their general health status is better than those born in the summer months. On the other hand, cows born in the warm months have more health problems such as reproduction, foot / hoof problems and mastitis. Such health problems lead to these cows being sold at an earlier age.

The researchers emphasized that these findings offer important opportunities to farmers. Managing calving season can be an important strategy to improve cow health and productivity. Farmers can extend the lifespan of cows and increase milk production efficiency by timing calving during the cooler winter months.
