Abstract:We researched the influence of two methods of housing primiparous cows on meeting estimated energy requirements.

The whole herd A consisted of 400 cows, where the average annual yield was 10,200 kg of milk per cow. Herd B consisted of 250 cows, where the average annual yield was 8,500 kg of milk per cow. In 2010 and 20… Show more
