In anaerobic glyoolysis lactic dehydrogenase (LDH) is the terminative enzyme in the sequence of reactions that promote the breakdown of sugars to lactate. The LDH activity of cattle semen and seminal plasma together with its relationship with various characteristics of semen have been reported (Stallcup & Hayden, 1960; Roussel & Stallcup, 1965). Such work in respect of buffalo semen is not available, although there are some reports on LDH activity of spermatozoa and seminal plasma (Singh & Sadhu, 1972; Chauhan & Srivastava, 1973). The present investigation was undertaken to determine the LDH activity of buffalo whole semen as well as of seminal plasma and to find correlations with some physical characteristics of semen.
