An investigation about the effects of insemination depth, cervico-vaginal mucus production and reflux of semen in the vagina after insemination in sheep

The possible influence of factors such as depth of insemination, cervico-vaginal mucus production and reflux of semen in the vagina after insemination in German merinolandrace were considered. Fresh diluted semen was inseminated intracervically. The results obtained for non-return-rate, lambing rate and fecundity are 49.01%, 39.75% and 64.55% respectively. The year had a significant effect (p less than or equal to 0.05) on non-return-rate and lambing rate but not on fecundity. The other parameters considered did not affect prolificacy significantly.
