In experiment 2, the semen quality of 2 boars from Ilan Yiyang farm were diluted with BTS and MIII extender and stored for 3 days in the initial stage. The parameters of semen quality were including pH, motility, maturation, acrosome integrity and normal morphology of spermatozoa in diluted semen stored for 1 and 3 days. The diluted semens were also used for in vitro fertilization to evaluate the sperm penetration, polyspermy rate and the average number of spermatozoa per oocyte as IVF parameters.
