Oestrus and ovulation were synchronised in 82 lactating Friesian dairy cows with two injections of dinoprost, and the cows were inseminated 72 and 96 hours after the second injection. Twenty-one of the 41 cows (51%) that had a 14-day interval between the dinoprost injections conceived to the inseminations, compared with 18 of the 41 cows (44%) which had an 11-day interval between the injections.
