A herd with high longevity
Farmers aim to build a herd that has the capacity to be milked for many seasons. Dairy cows that grow old are living proof that all has been well with their health, fertility and production. They also produce more efficiently, because older animals produce more milk than young ones. What’s more, they go on producing for longer, so they give more milk in relation to the energy – and time – invested in them during rearing.
