Studii privind influența mediilor de diluție asupra viabiltății spermatozoizilor și fecunditâții scroafelor

Abstract

The objective of this study was to examine the effect of storage duration of diluted boar semen on sows’ fecundation. The authors used in this experience the bio-preparation “Atropozit” and “M22” as components of the sperm dilution environment. Diluted semen was stored for a period of 2-3 days, 3-4 days, 4-5 days and 5-6 days at a temperature of 16-18 0 C. The fertility rate of sows inseminated with diluted semen that was stored for 2-3 days was different if compared with the semen stored for 4-5 and 5-6 days depending on the used dilution environment. The sows inseminated with diluted semen with the dilution environment in the composition of which the bio-preparation “Atropozit” was introduced and which was kept at a temperature of 16-18 0 C for 5-6 days, had a fecundity rate of 70%, and when the preparation “M22” was introduced in the composition of the dilution environment, the fertility rate was 68.7%. The obtained results show that sows’ fecundity is influenced by the dilution environments composition and by the storage duration of semen at temperatures of 16-18 0 C.
