Scrotal Circumference and Its Relationship with Testicular Growth, Age, and Body Weight in Tho Tho (Bos indicus) Bulls

Scrotal Circumference and Its Relationship with Testicular Growth, Age, and Body Weight in Tho Tho (Bos indicus) Bulls

The present study was undertaken to assess the relationship between the scrotal circumference and testicular parameters with body weight and age in Tho Tho bulls (Bos indicus), which were maintained at around the villages of National Research Centre on Mithun (ICAR), Jharnapani, Nagaland, India. A total of 32 Tho Tho bulls were selected and divided into four groups according to their age and ea...

Testicular thermoregulation in Bos indicus, crossbred and Bos taurus bulls: relationship with scrotal, testicular vascular cone and testicular morphology, and effects on semen quality and sperm production.

Mechanisms of testicular thermoregulation, the relationship of scrotal, testicular vascular cone (TVC), and testicular morphology with thermoregulatory capability, and their effects on semen quality and sperm production were studied in 20 Bos indicus, 28 crossbred, and 26 Bos taurus bulls. The ratio of testicular artery length and volume to testicular volume were larger (P<0.05) in B. indicus a...

Effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus bulls.

The objectives of the present study were to evaluate the effects of scrotal insulation on sperm production, semen quality, and testicular echotexture in Bos indicus and Bos indicus x Bos taurus crossbred bulls. In one experiment, B. indicus bulls (n=12) were allocated to control and whole-scrotum insulation groups, while in a second experiment, crossbred bulls (n=21) were allocated into control...

Relationship between Scrotal Circumference, Quantitative Testicular Traits and Growth Performance in Tropically Adapted Yearling Beef Bulls Differing in Age

Growth Rates of Hip Height, Scrotal Circumference and Weight for Purebred Hereford and Angus Bulls

Story in Brief Seasonal differences and growth rates were studied on 60 Hereford and Angus bulls born in the spring and fall calving seasons at Oklahoma State University. Hip height, scrotal circumference and weight measurements were taken over the two IO-month experiments. Season of birth had no influence on scrotal circumference for either Hereford or Angus bulls. Season of birth in Angus bul...
