THE DECAPITATED SPERM DEFECT

More than 50 percent of sperms have separation of loose heads and tails.

• Detached tails are bent around a distal droplet and most of the tails exhibit active motility.
• The defect is hereditary in nature and affected bulls are sterile.
• This defect is mostly seen in Guernsey breed.
