Tokom nekoliko zadnjih decenija, genetski napredak u proizvodnji mleka, povezan sa primenom novih reproduktivnih tehnologija, doveo je do znacajnog smanjenja fertiliteta u zapatima krava visoke mlecnosti sirom sveta. Produžen postpartalni anestrus j

Aim of study was to determine relationship between the energy status of cows, expressed through different milk fat to protein ratio values (FPR 1.3), and their reproductive performances (interval from calving to first artificial insemination; calving

This paper presents our results about the relationship between vaginal mucus electrical resistance values at the time of insemination and achieved cow’s pregnancy rate. We examined total of 130 cows, divided into three groups, based on the values o
