BIOMETRICAL AND PATHOLOGICAL STUDIES ON TESTES OF COW BULLS

Abstract

200 testes of cow bulls were collected from Mirpur Khas abattoir and were examined for biometrical values and pathological conditions. Out of 200 testes, 54 were collected from calves (below 01 year of age), 97 from steers (up to 03 years of age) and 49 testes from adults (age over 03 years). Out of 200 testes 57 were found affected (11 calves, 29 steers and 17 adult cow bulls). The mean length of left and right testes respectively was measured as 6.075 ± 0.214 cm and 5.763 ± 0.173 cm in calves, 8.602 ± 0.142 cm and 8.466 ± 0.143 cm in steers and 10.839 ± 0.097 cm and 10.701 ± 0.102 cm in adult. The mean breadth of left and right testes respectively was measured as 3.398 ± 0.173 cm and 3.269 ± 0.146 cm in calves, 4.863 ± 0.099 cm and 4.793 ± 0.87 cm in steers and 6.206 ± 0.134 cm and 5.919 ± 0.116 cm in adults. The mean circumference of left and right testes respectively was measured as 8.483 ± 0.309 cm and 8.226 ± 0.213 cm in calves, 12.612 ± 0.264 cm and 12.493 ± 0.259 cm in steers and 15.463 ± 0.326 cm and 15.296 ± 0.300 cm in adults. The mean weight of left & right testes was recorded as 16.841 ± 1.962 gm and16.639 ± 1.981 gm in calves, 62.689 ± 2.709 gm and 61.009 ± 2.369 gm in steers and 123.937±5.123 gm and 121.813 ± 5.269 gm in adults. Gross pathological lesions in affected testes varied and recorded: Orchitis 0.5% in calves, 2.5% in steers and 2.0% in adults; Hypoplasia 0.5% in calves, 1.5% in steers and 1.0% in adults; Cryptorchidism 1.5% in calves, 2.5% in steers and 1.5% in adults; Adhesions 1.0% in calves, 3.5% in steers and 2.0% in adults; Spermatocele only 1.0% in calves and 1.0% in steers; Degeneration 1.0% in calves, 2.0% in steers and 1.0% in adults and Hydrocele 1.5% in steers and 1.0% in adults were seen in affected testes during study period.
