[Clinical aspects and therapy of anaphrodisia in cows].

Clinical investigations were carried out of a total of 1675 cows to elucidate the reason for anaphrodisia. The functional activity of the ovaries was determined by the use of cytovaginal smears stained after Chamov. Animals with anaphrodisia on the base of ovarian hypofunction were treated with hormonal preparations of gonadotropic action, while those with persisting periodic corpora lutea--with prostanglandin or the yellow bodies were manually removed. it was found that anaphrodisia in cows was more largely due to ovarian hypofunction (78.5 per cent), and to a lower extent--to persisting yellow bodies (21.5 per cent). In the case of ovarian hypofunction very good results were obtained with the use of gravohormone and prolan, and in the case of persisting corpora lutea--with the use of prostaglandine F2 alpha. The manual removal was associated with low conception rate and higher index of insemination. The cytovaginal smears could be used as an adjunct for the indirect determination of the functional activity of the ovaries.
