Efecto del Flushing lumínico en la refrigeración de semen de conejo neozelandés.

Abstract

The objective of this investigation was to evaluate the effect of light flushing of rabbit semen on sperm quality during 24, 48, and 72 hours of sample refrigeration. There is sufficient evidence that light positively affects reproductive processes since it increases reproductive activity reflected on the physiology of rabbits, such as increasing libido in males. When studying this effect in the conservation processes of genetic material, the rabbit, due to its sensitivity, is an ideal species to understand the variables surrounding these processes, in this case, refrigeration and the light effect. To this end, 12 rabbits divided into two treatments were evaluated; the first with standard lighting and the second with 16-hour light flushing. Samples were collected in an artificial vagina and pooled into a sperm pool for each treatment for six replicates. The tests were contrasted using a t-student test, finding a greater quantity of nacre white colors in the samples with flushing and volume, concentration, and vitality (p<0.05). At the same time, refrigeration affected the decrease of sperm quality in both treatments. However, the number of abnormalities increased significantly (p<0.05) at 72 hours for the animals that did not receive flushing, concluding that flushing affects New Zealand rabbits' refrigeration time and sperm quality.
