The Influence of Microalgal Preparation Administration on the Cryoresistance of the Bull Semen Material

Abstract

The biopreparation’s effect of algal origin on cells semen’s cryoresistance and the reproductive system function of the sire bulls was established. BioR was influenced significantly (fig. 1) the cryoresistence of the semen material of sires bulls. To the end of the administration period (10 days), the group cured with 0,1 ml/ 100kg living mass /day showed an increase of the spermatic mobility with 69,14%, comparing to the preexperimental period. The group cured with 0,4 ml/ 100kg living mass /day showed an increase of 3,88%. The next 50 days from the ceasing of the preparation administration, the seminal cells mobility increased for the first group (0,1 ml/100 kg living mass/day)  with 107,14%, and for the second group (0,4 ml/100 kg living mass/day) this indices value maintains on the stage. The DMA concentration in blood for the first group was 3,74 mmol/l, 10 days after the administration we established an decrease of this indices till 3,12 mmol/l (P<0,05)and 50 days after this treatment ceasing the value of studded index was 2,95 mmol/l (P<0,05). The group carried with 0,4 ml/ 100 kg bodily weight /day shoved a tendency of decrease only 50 days from the ceasing of the preparation administration.
