Ultrasonographic characteristics of prostate and seminal vesicle glands in developing Murrah buffalo bulls

The study was performed in Murrah buffalo-bull calves to assess the developmental dimensions of the prostate and seminal vesicle (SV) glands from 1 to 30 months of age with transrectal ultrasonography. The width of prostate gland ranged between 1.39±0.07 and 2.65±0.14 cm. The rate of change in the mean width of the gland was gradual and almost same from one to thirty month (P<0.05). The correlation co-efficient between width of prostate gland and age was r2 = 0.73. The mean circumference and length of the SV gland at one month to thirty months of age ranged from 6.14±0.32 to 13.05±0.34 cm and 2.61±0.09 to 6.02±0.27 cm, respectively. The correlation co-efficient between length and age, width and age, and circumference of SV gland and age were r2 = 0.68, r2 = 0.55 and r2 = 0.74, respectively. From this study, it is concluded that the ultrasonographic evaluation of prostate and SV along with growth rate could be very practical tool for the assessment of puberty.
