THE EXTENTION OF CHRONIC UTER INE DISEASESIN COWS AND THEIR DIAGNOSTICS
The article presents materials on the degree of extension of chronic uterine diseases of functional and inflammatory character in cows depending on the duration of infertility and level of milk productivity and their differential diagnostics. It was found that the share of chronic uterine diseases in highly productive cows is 70.1 per cent of the total number of infertile animals. Among chronic uterine diseases, the highest degree of manifestation has chronic subinvolution of uterus, diagnosed in 29.4 % of cases, chronic endometritis - 15.9 %, glandular cystic hyperplasia of endometrium - 11.4 %, endometrial hypoplasia - 7.4 % and pyometrium - 5.9 %. With the increase of infertility duration the frequency of diagnosis of chronic subinvolution of uretos and chronic endometritis decreases by 1.72 and 2.16 times, respectively, with simultaneous increase of glandular cystic hyperplasia and endometrial hypoplasia registration by 2.8 and 6.4 times, respectively.With the increase in milk productivity there is an increase in the incidence of chronic diseases of the uterus of inflam matory character, including chronic endometritis in 1.44 times and pyometers - in 1.55 times, as well as pathology of the uterus of functional nature in the form of endometrial hypoplasia - in 1.88 times.It chronic subinvolution of uterus the horns cavity dimension is 9.5 ± 0.62 mm on average, and the wall thickness is 13.4 ± 0.7 mm. In case of chronic endometritis cow uterus has a more pronounced cavityit is 18.4 ± 0.9 mm and filled with catarrhally purulent or purulent quatarrhal exudates, and in case of pyometra - is 67.8 ± 4.6 mm, and filled by exudates with medium and high density echopositive inclusion. In case of glandulocystica hyperplasia endometrium the uterine wall thickness is 6.5 ± 0.28 mm; in case of endometrium hypoplasia - till 3.5 ± 0.14 mm.
