DETERMINING THE LEVEL OF ESTRADIOL CONCENTRATION IN SERUM OF THE DOMESTIC CATS (FELIS CATUS) OVER THE PERIOD OF ONE YEAR
Reproductive ability of the domestic cats, based on the experience, varies, which depends on the range of both internal and external factors. Like their wild counterparts, the domestic cats reproduce several times a year; hence, they are polyestric animals. Actuality of endocrinological testing, considering the extreme importance of the ovaries in the neuroendocrinology system and the importance of impact of different factors, climatic factors in particular from the aspect of the onset and detection of estrus, prompted us to determine the frequency of estrus during the period of one year, based on the level of estradiol concentration in blood serum.
