Název v původním jazyce

Fatty acid content in milk of dairy cows on a diet with high fat content derived from rapeseed.

Popis výsledku v původním jazyce

Two groups of dairy cows, Czech Red-pied x Ayrshire x Red Holstein crossbreds, received a diet with either production mixture with rapeseed, rapeseed cakes and rapeseed oil (Energol; E-group; final feed mixture with 62 g of crude fat per kg of dry matter, DM) or control production mixture (C-group; crude fat content in total feed mixture 37 g/kg DM). Milk samples were taken on the 14th, 30th, 60th and 90th day of lactation, and basic milk constituents and fatty acid content in milk fat were determined.E- and C-groups did not differ in either milk yield or yield of milk fat, milk protein and lactose (P > 0.05). Lactose, calcium, milk protein and casein content increased linearly (P < 0.05) with the increasing day of lactation both in E-milk and in C-milk. Casein content in E-milk was lower (P < 0.05) than in C-milk but total lipid content did not differ (P > 0.05) from that in C-milk. Dietary rapeseed decreased (P < 0.05) palmitic acid content in milk by 20 percentage units and at the
