Effect of epididymitis on semen quality of rams.

: To better document the detrimental effect of ram epididymitis (RE) in large range flocks, a study was conducted to determine the correlation of palpable RE lesions and semen quality. Presence of leukocytes in the semen of rams affected with RE also was evaluated and found to correlate positively with RE lesions and inversely with semen quality. Rams with palpable RE lesions usually produced semen of reduced quality; however, some affected rams did produce good quality semen. The mean scrotal circumference varied significantly when rams were analyzed by breed, but not when grouped by RE status or classified by semen quality.
