Eighty – seven pairs of ovaries showing cyclic activity, nine pairs of ovaries from pregnant animals, 12 pairs of inactive ovaries and 1.4 pairs of senile atrophic ovaries were utilised for biometrical studies of ovaries, corpora lutea and graafian follicles.
While out of the 252 genitalia examined, 139 (55.16 per cent) showed one or more lesions of the ovary and bursa, only 39.28 per cent showed one or more lesions in the ovary. The ovarian pathological conditions were inactive ovaries (23.41 per cent), cystic ovaries (2.78 per cent), cystic corpora lutea (2.78 per cent), haemorrhage in the ovary (5.56 per cent), persistent corpus luteum (0.79 per cent), retention cyst (0.79 per cent), par ovarian cyst (3.17 per cent) and par ovarian abscess (0.40 per cent).
The incidence of pathological conditions of bursa was 26.98 per cent, which included bursitis and ovarobursal adhesion (25.79 per cent), hydrops bursa (0.40 per cent) and haemorrhagic bursitis (0.79 per cent). The most common type of bursitis was fibrinous which was the mildest and was of no significance in causing infertility. The strandular type of ovarobursal adhesions might lead to subfertility or infertility.
The weight and dimension of senile atrophic ovaries were significantly higher than those of ovaries in follicular and luteal phases of the cycle and inactive ovaries (P > 0.01). Similarly the weight and dimensions of ovaries in follicular and luteal phases of the cycle were significantly more than those of inactive ovaries (P > 0.01). However no significant differences in the weight and dimensions of ovaries in follicular and luteal phases of cycle and the right and left ovaries in both phases of cycle were noticed.
It may be concluded that the pathological conditions affecting ovaries and bursa of cross – bred cows slaughtered at local slaughter houses were fairly high probably on account of the fact that most of the cows slaughtered were problem breeders. The biometrical and gross morphological studies of the ovaries of cross – bred cows in cycle, anoestrum and senility would greatly help the clinician in differential diagnosis of these conditions.
