Use marking harnesses to determine the activity of the ram. Change colors every 14 to 17 days to determine if the ewes are being settled the first cycle. If a high percent of ewes are returning after 17 days, you should evaluate the ram. A semen check is in order. A semen evaluation before breeding season may eliminate this problem later in the season.
Testes Always check the testes for abnormal condition.
Although ram lambs seldom have epididymitis, it is a good policy to check for this disease. Also, examine testes for size and number. Sometimes a testicle is small and abnormal and it is not noticed without palpation. The scrotal circumference should be at least 9.5 inches mid-point of testes at five months. The larger the circumference of the scrotum, the more potential for fertility of the ram.
