title: The effect of reducing hindquarter elevation time after artificial insemination in bitches.
abstract: Hindquarter elevation time after artificial insemination in dogs was reduced from the common and arbitrarily used 10 min to only 1 min after insemination. Artificial insemination with fresh undiluted semen was conducted in 32 breedings using 15 hound bitches. The overall pregnancy rate was 91% (29/32), with an average litter size of 7.35 puppies per pregnancy. The pregnancy rate was not altered by reducing the 10-min (n = 14) hindquarter elevation time to 1 min (n = 18; P = 0.30). Similarly, the litter size was not different between groups (P = 0.40).
