Sažetak
S obzirom na značaj vitamina E u ishrani visokomlečnih krava, napravljen je pregled novije dostupne literature o njegovoj hemijskoj prirodi, metabolizmu, zastupljenosti u krmivima i efekti njegove upotrebe na zdravstveni status i proizvodne sposobnosti kod krava. Kao rezultat postignutih saznanja za mesto i ulogu vitamina E u ishrani krava urađeni su novi normativi čija se količina povezuje se sa proizvodnom fazom kod krave i iznosi od zasušenja (60-70 dana pre telenja) do 3 nedelje pre telenja - 1000 mg/dnevno; 3 nedelje pre i 4 nedelje nakon telenja (tranziciona faza) - 3000 mg/dnevno; 5 do 10 nedelja nakon telenja - 1000 mg/dnevno i od 11 nedelje laktacije do zasušenja - 500 mg/dnevno. Povećane količine vitamina E u tranzicionoj fazi imaju značaj u redukciji pojave infektivnih i metaboličkih bolesti kod krava, odnosno poboljšanje imunološkog sistema. On smanjuje rizike povezane sa pojavom mastitisa i poboljšava reproduktivne funkcije.
