"He's a real bargain," Marcia said, and named a price per straw of frozen semen that Cecelia didn't think was a bargain at all.

Using frozen semen for dairy cattle has been done since the 1950s.

From time to time calves will still be born from his frozen semen.

The breed is in danger of extinction, with only around 130 females in the herdbook and frozen semen from around eleven males.

Beginning next year, however, frozen semen will be allowed by the United States Trotting Association.

Due to frozen semen, it is still possible to breed to the legendary stallion.

The first use within the breed of artificial insemination through frozen semen was with several Australian mares in 1997.

This year, 591 purebred litters have been produced from frozen semen, according to the American Kennel Club; in 1990, there were 44.

The overall trend is toward permitting use of frozen semen after the death of the stallion.

However, the use of fresh, as opposed to frozen semen will mean that a sample has a greater fecundity and this can produce higher pregnancy rates.
