A.S. Series 69-43
Fertility of boar semen stored under present conditions is at best only adequate after 24 hr. of storage and decreases sharply thereafter. It is usually recommended that boar semen not be stored more than 48 hr. for artificial insemination use. The goal is to find a means whereby boar semen fertility could be retained indefinitely by freezing. Until a success full freezing technique is found, a method of storing boar semen for a period of four to five days at above freezing temperatures would be of value to artificial insemination of swine. The objective of this experiment was to study the effect of removing the seminal plasma immediately after ejaculation on the in vitro survival of spermatozoa.
