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.

试验二使用宜兰宜阳养猪场之2头性成熟公猪，采取精液后分别以BTS与MIII稀释液进行稀释，在保存1日与3日时检定其pH值、精子活力、成熟率，形态正常率等性状，并用此稀释保存之精液进行体外受精，纪录精子穿透率、多精入卵率与平均入卵精子数。
