The influence of nutrients content in pasture on amino acids content of cows milk

Popis výsledku v původním jazyce

The chemical composition of milk and its relation to grazing is emphasized in low-input breeding systems where generally lower milk production use to be achieved. The aim of this study was to evaluate the milk composition of Czech Pied and Holstein cowsduring 6-months grazing period in comparison to winter silage-based breeding on three sub-mountain farms. The individual 24-hours milk yields and concentrations of fat, protein and somatic cell counts (SCC) were measured monthly in a total of 671 Czech Pied and 114 Holstein cows during 6-years period. Cows belonged to two Czech pied herds, offered 7-hours (Farm 1, F1) or 20-hours (Farm 2, F2) daily grazing allowance, and to a mixed Czech Pied and Holstein herd (Farm 3, F3), offered 20-hours pasture access. The data of each herd were evaluated separately allowing to the season (grazing, housing) and the breed. A significant enhancement of fat yields was found during grazing season in all three herds and in both the breeds. The higher pro
