Název v původním jazyce

Differences in the occurrence of selenium, copper and zinc deficiencies in dairy cows, calves, heifers and bulls

Popis výsledku v původním jazyce

This study was conducted to evaluate the mineral status of various bovine categories reared in the same farm, and in this way to monitor the quality of their mineral nutrition. Blood samples were collected in 20 farms in various regions of the Czech Republic to diagnose the selenium (Se), copper (Cu) and zinc (Zn) status of dairy cows, calves, heifers and bulls. Dairy cows and calves showed lower GSH-Px activity in comparison with heifers and bulls. Se deficiency was diagnosed in 23% of individual dairycows examined, 31% calves, 51% heifers and in 58% bulls. Dairy cows showed lower Zn and higher Cu concentrations in comparison with other categories. Zn deficiency was diagnosed in 41% of individual dairy cows examined and 13% of bulls. None of the calfor heifers herds were classified as Zn deficient. Cu deficiency was diagnosed in 28% of individual dairy cows examined, 70% of calves, 65% of heifers and 70% of bulls.
