Description
Zulfi Nur Amrina Rosyada and co-authors looked in 2026 at whether age changes the DNA packaging inside Bali bull sperm, a factor in fertility at insemination centers. Eight bulls were split into younger and older groups around the ten-year mark. Sperm movement was tracked by computer, while staining tests measured cap integrity, DNA breakage, and protamine, the protein that tightly packs sperm DNA.
Older bulls surprised expectations with better forward movement and better protamine packaging than the younger group, while cap integrity and DNA breakage matched. Protamine status tracked movement closely across bulls. A protein band near 10 to 11 kilodaltons also ran stronger in older bulls. The authors suggest adding packaging checks to routine bull selection.
