Flow cytometry data on the effect of dimethylacetamide and N-methylacetamide used at different concentrations on the quality of cryopreserved chicken semen

Abstract

This article includes supporting data regarding the research article entitled “Concentration dependent effect of dimethylacetamide and N-methylacetamide on the quality and fertility of cryopreserved chicken semen” (Zaniboni et al., 2022). The effect of two permeant-cryoprotectants (CPA), dimethylacetamide (DMA) and N-methylacetamide (NMA) used at different concentrations (0, 2, 4 and 6%) on the quality of post thaw rooster semen was assessed. Ejaculates were processed according to 7 treatments: Lake pre-freezing+0.1 M trehalose (LPF-T) (control treatment), LPF-T+2% DMA (DMA2), LPF-T+4% DMA (DMA4), LPF-T+6% DMA (DMA6), LPF-T+2% NMA (NMA2), LPF-T+4% NMA (NMA4), LPF-T+6% NMA (NMA6). Sperm acrosome integrity and mitochondrial activity were investigated in frozen-thawed semen with the use of the flow cytometry technique. Only the mitochondrial activity was significantly affected by the different cryoprotectant concentrations.
