Low density lipoproteins (LDL) extracted from hens egg yolk (EY) has been studied over EY based extender for liquid storage of mithun semen with the objective to explore the use of LDL in place of EY. Physio-morphological attributes (PMAs) and mobility and velocity parameters were measured by computer assisted sperm analyser (CASA). Leakage of intracellular enzymes, activity of total antioxidants and lipid peroxidation following liquid storage (5oC) of mithun semen were studied. Fifty ejaculates were collected through transrectal massage method from matured mithun bulls and based on the mass activity and individual motility; the semen samples were splited into good and poor quality and diluted with the tris citrate glycerol (TCG) extender and were splited into three equal aliquots: Group I: Control, EY; Group II and Group III contained 8 and 10% LDL (w/v), respectively. PMAs, intracellular enzymatic leakage and biochemical profiles were evaluated at 5°C following 10hrs incubation. Result revealed a significant (p<0.05) improvement in PMAs, CASA parameters and cholesterol content of spermatozoa as well as reduction in leakage of intracellular enzymes, oxidative stress in Group II than control and other treatment group. It was concluded that addition of 8% LDL holds a clear advantage over EY or 10% LDL in liquid preservation of mithun semen.
