Vets de­liver high rate of AI suc­cess

Central and North Burnett Times - - THE FENCE POST - Emily Smith

RAIN has helped Stacey Rae and Matthew Lit­tle­ton from Monto Vet Surgery come back with a near-per­fect suc­cess rate in ar­ti­fi­cial mare in­sem­i­na­tion (AI) over the past year.

“The rain im­proves the health of the mare and that makes for a bet­ter suc­cess rate,” Mr Lit­tle­ton said.

“Other things that de­ter­mine the suc­cess are things like the age of the mare and her breed­ing his­tory.”

AI has been around for years now, but its pop­u­lar­ity is on the rise as horse own­ers be­come more con­cerned with their an­i­mals’ blood­lines.

“Most of the peo­ple we see want an­i­mals with par­tic­u­lar traits for dif­fer­ent horse sports,” Ms Rae said.

“And it makes a lot more sense for stal­lion stud own­ers to send se­men up to us, than for mare own­ers to take them all the way to the stud, which might be in Vic­to­ria or Amer­ica.”

Once a mare owner has re­searched a par­tic­u­lar stal­lion they want to breed with, Ms Rae con­tacts the stal­lion owner and ar­ranges for se­men to be sent up.

“We have been greatly suc­cess­ful with both frozen and fresh se­men,” she said.

“Fresh se­men gen­er­ally comes from an Aus­tralian stud and was col­lected within three days, while frozen can come from over­seas, like the USA.”

After the AI a scan after 14 days will re­veal if the mare is preg­nant, and another one at 45 days will check it has been main­tained.

“We nor­mally have the mare for seven days though, so we can de­ter­mine the best time to put the se­men in,” Ms Rae said.

In a breed­ing sea­son Ms Rae said they usu­ally do be­tween 30 and 40 AIs although they are limited for space as they keep the mares for the week.


MON­I­TOR­ING: Matthew Lit­tle­ton takes care of a quar­ter horse as vet Stacey Rae screens it to see if an ar­ti­fi­cial in­sem­i­na­tion had been suc­cess­ful.
