The effect of reducing hindquarter elevation time after artificial insemination in bitches

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...

Description
Summary: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).
