Abstract

|
|
This study was carried out to find out the effect on fertilizing capacity according to sperm concentration of liquid boar semen. Four different doses with various motile sperm cells of 3.0times10^{9} , 2.5times10^{9} , 2.0times10^{9} , and 1.5times10^{9} per 80mell plastic bottle were inseminated twice 12 h interval after standing estrus in 6,818 sows. Farrowing rate and total piglets per litter were 82.2% and 10.9, respectively, with no significant differences among the other treatments. The presumption of optimal concentration of motile sperm cells in the liquid boar semen was best at 2.0~2.3times10^{9} per dose.
