The effect of selenium and vitamin E on the health condition of mammary glands in cow

Abstract

In this paper the literature data on the effect of Se and vitamin E on health condition of mammary gland in cows have been discussed. The frequency and occurrence of mastitis are in correlation with the status of vitamin E and Se, and they are connected with rate of clinical mastitis and somatic cells count in collected heard milk. Supplementation of these micronutritients in Se-deficient cow rations results in improving of immunological response. In rations for high-productive cows in intensive production more than often the share of these nutrients is less than necessary what can partly explain the frequent occurrence of mastitis in our country.

U radu su sagledani literaturni podaci o uticaju Se i vitamina E na zdravstveno stanje mlečne žlezde krava. Učestalost pojave i izraženost mastitisa u korelaciji su sa statusom vitamina E i Se, a u vezi su i sa stopom kliničkog mastitisa i brojem somatskih ćelija u zbirnom mleku stada. Dodavanje ovih mikronutritienata u hranu kod postojanja deficita rezultira poboljšanjem imunološkog odgovora. U obrocima za visokoproduktivne krave u intenzivnoj proizvodnji često je njihova zastupljenost manja od potrebne, što delom može objasniti povećanu učestalost pojave mastitisa u našoj zemlji.
