| Composition of milk and blood metabolities in high prodaktivity dairy cows on pasture | |
Abstract/OtherAbstract

|
The study has involved a comparison of yield performance of Holstein-Friesian cows (n=38) fed conserved feeds (grass silage, maize silage, ensiled beet pulp) with their analogues grazing on pasture. Pasture grazing increased the milk yield performance of cows compared to the feeding method based on conserved feeds, with the increase accompanied by an elevated level of urea in milk. The basic chemical composition of milk did not vary much from one feeding system to the other. However, daily fat and milk yield is improved when cows receive green pasture fodder. |
