  • Reproductive Capacity of Dairy Bulls. I. Technique for Direct

    A technique for determining the gonadal and extragonadal sperm reserves of bulls by direct counting is described. Sperm were liberated from the epididymis by thoroughly tearing apart the tissue in 50 ml. of 0.9% NaCl and grinding the tissue suspension in 200 to 500 ml. of saline for a total of 2.5 min. in a Waring Blendor.
