A Review.	2011	14	.pdf	application/pdf	8729	483	54	Lunstra DD, Gregory KE, Cundiff LV: Heritability estimates and adjustment factors for the effects of bull age and age of dam on yearling testicular size in breeds of beef bulls. Another study testing physical and semen traits in yearling beef bulls (Angus, Brahman, Hereford Senepol, Romosinuano and Nellore x Brahman) in Florida showed that qualitative semen traits increased with bull age, particularly from 12 to 18 months.36 Bull age was positively associated with normal spermatozoa (P<0.01) and negatively with primary abnormalities (P<0.001), with breeds differing in their age curves for both traits.	cache/ct-10137.pdf	txt/ct-10137.txt
