SCROTAL CIRCUMFERENCE OF YOUNG BEEF BULLS: RELATIONSHIP TO PAIRED TESTES WEIGHT, EFFECT OF BREED, AND PREDICTABILITY

A Comparison of Different Breeds for Growth Rates, Performance Traits and Scrotal Circumference in Young Beef Bulls

spring (a cow changing from a 6.0 to a 4.8) would be associated with an additional 15 days to first estrus after calving compared to a cow that maintained body condition. Similarly, a 20 percent decrease in body condition score would be associated with an additional 16 days to conception. This study reemphasized the relationship between weight loss during pregnancy and rebreeding performance. E...

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...

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...

Changes in mean scrotal circumference in performance tested Swedish beef bulls over time

BACKGROUND There is a growing interest in beef cattle breeding in Sweden. The majority of the females are bred naturally, which is why it is important to choose healthy fertile bulls to obtain good reproduction and profitability. The breeding soundness evaluation includes measurement of scrotal circumference (SC). Our aim was to analyze if the SC of performance tested beef bulls has changed ove...
