Cryopreservation of boar sperm

Abstract

Cryopreservation of pig sperm is still rarely used in the artificial insemination industry due to the low percentage of fecundity after resuscitation. The research carried out for the purpose of freezing the sperm of the male was meant to meet several goals, namely to establish the efficiency of the freezing by using several media intended for the dilution and freezing of the seminal material. The results of the research demonstrated that the mobility of spermatozoa after resuscitation was 41.0%, spermatozoa with progressive movements 21.3% and the viability after 4 hours of storage of spermatozoa at + 37 degrees C of 8.0+4.2, spermatozoa with progressive movements of 2.0+1.0 compared to the control group 25.5+1.7, 10.0+1.0, consecutively when the sperm was diluted with GHȚS medium.
