Alternative adjustment of scrotal circumference for growth traits in Nellore cattle
The objective of this study was to estimate adjustment factors of scrotal circumference for growth traits in Nellore cattle. Measurement at post-yearling of scrotal circumference from 100,107 Nellore was adjusted for six traits: age (A), body weight (BW),

Anti-Müllerian hormone concentration and scrotal circumference as predictors of fertility-linked characteristics in male Brahman and Simmental bulls [PDF]
This study investigates whether pre-pubertal scrotal circumference (SC) and anti-Müllerian hormone (AMH) concentrations indicate sexual precocity in Brahman and Simmental bulls. Fifty-three bulls (Brahman, n = 27; Simmental, n = 26) were used.
