Dimethyleacetamide improves the cryosurvivability of Indian red jungle fowl (Gallus gallus murghi) sperm

Résumé

It was hypothesized that dimethyleacetamide (DMA) can be used as an alternate to glycerol for cryopreservation of Indian red jungle fowl semen. Four concentrations of DMA (4%, 6%, 8% and 10%) in extender were compared with previously optimized cryopreservation protocol based on 20% glycerol (control) for Indian red jungle fowl. Sperm motility, plasma membrane integrity, viability, and acrosome integrity were assessed at the stage of post-dilution, cooling, equilibration, and freeze-thawing. The whole experiment was repeated/replicated for five times independently. Sperm motility, plasma membrane integrity, viability and acrosome integrity were recorded highest (P < 0.05) at post-dilution, cooling, equilibration, and freeze-thawing in extender having 6% DMA compared to control and other experimental extenders. The highest (P < 0.05) recovery rates of all aforementioned parameters were also recorded in extender having 6% DMA; thus, 6% DMA was further compared with control (20% glycerol) for fertility after artificial insemination. Eggs were collected for five days after artificial insemination with semen cryopreserved in extender containing 6% DMA and control. The higher no. of fertilized eggs, fertility, no. of hatched eggs, hatch (%) and hatchability were recorded with semen cryopreserved in extender having 6% DMA compared to control. It is concluded that 6% DMA maintained higher post-thaw quality and fertility of Indian red jungle fowl semen and is a better replacement of glycerol.
