Heteroplasmic and heterospermic studies of Ganguli (1978) revealed that the seminal plasma plays a definite role in spermatozoan motility, survival and viability. Protein may increase the the permeability of biological membranes and it has been suggested that the basic proteins of the seminal vesicles have a similar effect on the membrane of spermatozoa (Hibbitt and Benians, 1971). High protein content in boar semen was shown to render the sperm cell membrane susceptable to injury by cooling and deep freezing (Lavon and Boursnell, 1971).EnglishVeterinary ScienceAnimal Genetics and BreedingArticle
