The effect of proctodeal gland foam, diluent and dimethylacetamide addition on morphology and fertilizing ability of Japanese quail (Coturnix japonica) spermatozoa.

摘要

The effect of proctodeal gland foam addition to fresh net or diluted semen supplemented with (DMA) dimethylacetamide on morphology and fertilizing ability of quail (n=75) spermatozoa was evaluated. Every stage of quail semen preparation caused an increase in sperm deformations. The addition of foam, diluent and DMA decreased the number of morphologically intact spermatozoa by 28.3% in relation to the fresh semen. Foam addition to the fresh semen resulted to 91.4% fertility, which was similar to results obtained during natural mating (93.0%). However, in diluted and DMA supplemented semen, equilibrated for 5 min at 4 degrees C, the foam had a detrimental effect on the fertilizing ability of the spermatozoa..
