[Effect of sugars on the biological properties of bull spermatozoa after cryopreservation].

Abstract

An investigation was carried out on the protective qualities of some type of sugars as ingredients of the g X22l diluent with regard to bull spermatozoa upon freezing after the granule technology. It was ascertained that sugars varied in effect. On the base of the results obtained a new diluent was developed under the conditional name of g X22A, with better cryoprotective qualities than those of the currently used diluents. The optimum effect of semen dilution with the granule technology of freezing of g X22A proved within the range of 1 + 4 to 1 + 8.
