Cryoprotective effect of glycerol concentrations on Indian Red Jungle Fowl (Gallus gallus murghi) spermatozoa

Posted on 20. August, 2018.

Semen cryopreservation protocols for wild avian species need to be optimised in order to achieve optimum post-thaw sperm quality and fertility. The present study was designed to evaluate the cryoprotective effect of different glycerol concentrations (11%, 15% and 20%) on post-thaw quality, recovery rates, absolute livability index and fertility of Indian Red Jungle Fowl (Gallus gallus murghi) semen.
