Interpretive Summary: This is a general protocol for cryopreservation of rooster sperm using dimethylacetamide (DMA) as the cryoprotectant. One advantage of using a DMA-based diluent is that the cryoprotectant does not have to be removed from thawed semen prior to insemination. Dimethylacetamide is most effective at very fast freezing rates achieved with the pellet method. Use of straw packaging in conjunction with DMA is still being investigated.
