title: Effect of temperature of thawing and diluent on the post--thaw physiological changes of buffalo frozen semen.
abstract: The effect of thawing was studied in buffalo semen diluted in three diluents (Tris egg-yolk, Egg-yolk citrate and Citric Acid whey) at three temperatures (5 degrees C, 35 degrees C and 75 degrees C) on motility, eosin staining, morphological and acrosomal changes, hyaluronidase, glutamic oxalacetic transaminase and glutamic pyruvic transaminase activities. The motility and lack of staining of sperm by eosin were maximum on thawing at 35 degrees C and in tris egg-yolk diluent followed by egg-yolk citrate and citric acid whey. Hyaluronidase, glutamic oxalacetic transaminase and glutamic pyruvic transaminase increased significantly in the extra-cellular fluid on thawing of semen diluted with all the three diluents. The buffalo semen diluted in tris egg-yolk and thawed at 35 degrees C for 30 seconds gave the best results.
