Study was undertaken to investigate the fertility of frozen semen from three Nili-Ravi buffalo bulls using three different extenders. Semen was extended in milk-yolk-glycerol, lactose-yolk-glycerol and fructose-lactose-yolk-glycerol, kept in 0.5 ml straws and frozen in liquid nitrogen. Only normal cyclic buffaloes were inseminated with the post-thaw semen. Fertility was based on pregnancy test through rectal palpation at 45 to 50 days post insemination. Milk-yolk-glycerol extender showed the best fertility result (49.82 percent) among all the extenders (45.68 percent for lactose-yolk-glycerol and 39.01 % for fructose-lactose-yolk-glycerol)
