EFFECT OF THREE DIFFERENT EXTENDERS IN SLOW FREEZING PROTOCOL ON POST-THAW QUALITY OF DOG SEMEN*

Forty dog semen ejaculates were diluted in three extenders at the rate of 1:3, and subjected to slow freezing in a programmable freezer. Tris and Triladyl extenders were superior and significantly different from Laiciphos-488 (p< 0.01) on postthaw values for motility, live sperm and membrane integrity in slow freezing protocol.
