The use of intrauterine method, and possibly innovation of new modification and training expertise would help to improve fertility in bitches, and more work is needed to accurately predict fertility of cryopreserved canine sem*n.

Data show, for the freezing method used, that the results of artificial insemination with frozen sem*n in the bitch are better with intrauterine than with intravagin*l deposition.

The intravagin*l artificial insemination was carried out in bitches with fresh sem*n and the number of sperms and the quantity of sem*n required for conception was examined to obtain a similar rate of conception and number of offspring as in naturally breeding bitches.

Among bitches artificially inseminated with frozen sem*n from various sources, non-pregnant bitches had significantly lower mean plasma progesterone concentrations at the second insemination than did pregnant bitches, and this indicates that the secondInsemination was performed too early.

During 1990 and 1991, 527 artificial insemination (AI) procedures were performed by 40 veterinarians, under the Swedish Kennel Club control scheme, and reported to the Kennel Clubs within 14 days, with significant differences in fertility between breeds.

There was a tendency for bitches treated with antibiotics at the time of mating or during early pregnancy to have a higher pregnancy rate and a larger litter size, and for breed differences in pregnancy rate, although not significant.
