title: Plastic straws for frozen semen. (A field evaluation).
abstract: A field trial was conducted to compare the routine frozen semen methods presently used at this laboratory with those reported by French workers. When the extender used was sterile milk both methods resulted in fertility equal to the standard. Fertility results obtained with the French method employing Lactiphos extender were significantly lower than the standard.
