Influence of BioR preparation on boar spermogram

Abstract

The aim of the research was to study the influence of biologically active preparations, extracted from Spirulina platensis (BioR) on the quantitative and qualitative indices of the usual spermogram in boars. The biological studied material was the Landrace boars and the semen material taken from them, raised at M. S. Moldsuinhibrid, Orhei, Republic of Moldova. The experiments were carried out between July and August, the months with hot temperatures. The boars were administered BioR preparation intramuscularly 0.3 ml / 100 kg live mass for 5 and 10 days, the preparation being produced at the Institute of Microbiology and Biotechnology of the Republic of Moldova. The sperm indices were studied before administration and 50 days after cessation of administration. The results showed that the mobility of sperm after 5 days of administration was 90%, after 10 days - 91%, compared to the control group where the mobility was 82% lower; the volume of ejaculate was 213 ml after 5 days and 229 ml after 10 days of administration of the preparation or by 25 ml and 41 ml, compared to the control group, and the fecundity increased by 3.29% and 4.57% compared to the control group where this index was only 75.83% (80.4% when the BioR preparation was administered for 10 days, and it was 79.12% after 5 days of administration).
