Quality of ram semen in relation to scrotal size

Aim of this study was to select superior rams by assessing their scrotal size and quality semen. In ten indigenous Bangladeshi rams, the body weight, circumference, volume increased with age (P<0.05). Body weight at 381-410 days (13.6 ± 1.5 kg) higher than 169-200 (10.2 0.1 201-230 (10.4 1.2 (p<0.05). Scrotal circumference 381 - 410 (19.1 0.3 cm) (p<0.05) 169 200 (17.2 cm), 201 230 0.6 231 260 0.5 cm). At days, (87.4 5.5 cm3) in five youngest groups Both were positively correlated (R2=0.519) weight. Semen age, which varied from 0.4 0.0 ml. The semen (1.2 ml) other (P<0.05) except for 351 380 days. mass activity sperms different 2.8 4.3 0.3. Sperm concentration, progressive motility (%), normal spermatozoa (%) improved progressively but significant changes these parameters seen when animals reached 291 or more However, 261 sperm concentration (R2 = 0.568) 0.616). Measurements scrotum could provide a reliable guide estimating production capacity, are important breeding soundness evaluation, genetic improvement rams.
