FERTILIZATION CAPACITY OF BOAR SEMEN RELATED TO DILUTION AND DURATION OF PRESERVATION
Elena Marandici, G. Darie
Abstract
The objective of this study was to examine the effects of duration of storage of diluted boar semen fertilization rate in sows. The experience was used the "Atropozit" and "M22" bioproducts as diluents for boar sperm. The diluted semen was stored throughout periods of 2-3 days, 3-4 days, 4-5 days and 5-6 day at 16- 18°C. The fertility rate of the sows inseminated with diluted semen and stored 2-3 days was different compared to that achieved when used semen was stored for 4-5 days and 5-6 days, depending on the solvent used. Sows inseminated with semen diluted with "Atropozit" and stored at 16-18°C, during 5-6 days had a fecundity of 70% while in the sows inseminated with sperm stored in "M22" diluent, fecundity reached 68.7%.
