Helpful Or Harmful: Jury’s Still Out On CBD Oil For Older Horses

Cannabidiol (CBD) has been touted to help just about everything from pain and anxiety to inflammation. But what does the drug offer older equines? No one is quite sure. 

Low doses of CBD don't seem to affect lameness, body condition, or weight in senior horses – but there don't seem to be any negative effects of its use, either, reports The Horse. So while it doesn't do a lot, it also doesn't hurt. 

Hemp-based CBD, which has no psychoactive effects, has gained popularity among animal owners seeking to provide their pets relief, though no studies have confirmed benefits from its use. Horse owners in particular have been using CBD in an attempt to offer their horses relief from the low-grade inflammation associated with aging, sometimes called “inflamm-aging.”

It isn't clear if inflamm-aging contributes to age-related diseases like osteoarthritis, but it may. If horse owners can regulate the inflammation by using CBD, it may help the horse. 

CBD has been shown to relieve inflamm-aging in humans by reducing the pro-inflammatory cytokine production and balancing oxidative stress. Dr. Amanda Adams and Shelley Turner, with the Gluck Equine Research Center at the University of Kentucky, sought to determine whether CBD affects the immune function of senior horses.

The duo created a study to see if CBD would affect inflammatory cytokine production and antibody response after a flu vaccine, possibly negatively impacting the horse's immune response to the vaccine. 

Adams and a group of other scientists created a three-month-long study using 27 healthy senior horses that lived on pasture, dividing them into two groups. Half of the horses got a dose of CBD made from hemp extract at 2 mg/kg orally. The CBD was dissolved in about 15 milliliters of soy oil. The other group received just the soy oil.

Blood samples were taken just before giving the horses their CBD and oil or oil alone on days 0, 30, 60, 90, 104 and 111. On day 90, the scientists also took blood samples 4 hours after treatment, right before all the horses were vaccinated for equine influenza.

The only thing that changed significantly in the blood panel was an increase of albumin in horses that received CBD supplementation. Albumin plays a role in circulation. The control horses also showed an albumin increase at day 90, suggesting that an external factor is affecting albumin levels of all study horses.

CBD supplementation at this dose and over the time period did not appear to affect the liver, Adams said. Additionally, the research team found similar metabolic and inflammatory responses in both groups, indicating that CBD does not have a direct effect on lymphocyte production. 

CBD did not affect the horse's antibody responses after the flu vaccine, which is good news, Adam said, as older horses often have a lower immune response to vaccinations than younger horses. 

Though the CBD was detectable in the study horse's plasma, the lack of impact on treated horses may be related to the amount or timing of the dose administered in the study. Adams recommends additional research be completed to determine the best dose, time of administration, and formulation to make CBD more bioavailable to the horse.

At this point in time, it is still unclear whether CBD is helpful or harmful to horses, she concluded.

The X-Ray Files: Ciaran Dunne

Ciaran and Amy Dunne's Wavertree Stables is perennially one of the leading consignors of 2-year-olds in the country, but their process for buying pinhooking prospects at the yearling sales changed dramatically with the advent of the sales repository over two decades ago.

“We started buying yearlings before the repository,” Ciaran Dunne said. “Back in those days, you had to shorten down your vet list because of the costs involved. There was very little that we couldn't live with because we might vet, at the very most, four horses a day. So if you were very picky, you didn't get anything. Back in those days, sesamoiditis wasn't as big a deal, there was no such thing as ultrasounds and soft tissue scans. So very early on we learned to live with a lot of things. And because of that, we trained horses who had various issues. We saw a lot of what horses can live with and what horses can't live with.”

Dunne said his decisions at the yearling sales are generally based more on the individual in front of him than on the expansive vet reports available today.

“Some years, I will say I'm not going to buy any horse that has any degree of sesamoiditis above mild,” he explained. “But if I find a horse I really, really like and he's got moderate or severe sesamoiditis and I still like him, I'll probably still buy him. I think if we allow the veterinary findings to dictate what we buy, then a lot of times you end up buying horses you are just OK on physically and you walk away from the ones you love because they have some little issue that might never have been a problem. I take the tact that I would much rather buy one that I love that has a little this or a little that than buy one that I'm just so-so on because he has a clean set of X-rays.”

The Wavertree team doesn't adjust its process just because they are predominately shopping for pinhooking prospects, rather than racehorse prospects.

“I have people tell me, 'He'll be OK to race, but not to pinhook,'” Dunne said. “Ultimately, they are all going to have to be racehorses. And I can't be a future purchaser's veterinarian. I can't say what they will like and what they won't like. There are plenty of horses that come with veterinary findings that are of no consequence to me, but the buyers run away from and hide. And then there are horses that, when we get the X-ray report back after the breeze show, I think we are in trouble here and nobody else seems to have a problem with it.”

Buyers relying solely on a vet report while neglecting to consider the individual may be missing the bigger picture, according to Dunne.

“I'm not going to say that everything with bad X-rays or a bad ultrasound will go on and run,” he said. “I think everything is relative. Some horses who have issues, if they have a lighter frame they can maybe live with them, whereas with a heavier-bodied type, you'd be less inclined to give them a chance. I think people use the vet reports to weed horses out, but I don't think you can look at a vet report and say this horse is no good.”

He continued, “In the same way, when people read X-rays or  read soft-tissue findings and aren't physically there to look at the horse, I don't think they can give a fair judgement on whether this is representative of what the horse actually is. Trying to evaluate a horse off a piece of paper in terms of radiographic findings or trying to evaluate a horse digitally from 500 miles away, I don't think that works. I think there has to be a little common sense. Context matters.”

When Dunne switches from buying yearlings to selling juveniles, he sees a difference in how potential buyers utilize vet reports.

“I think they are harder on the 2-year-olds than they are on the yearlings with the vetting,” Dunne said. “We've seen a lot of yearlings sell for a lot of money with radiographic findings that really raised our eyebrows. Whereas the slightest thing in the 2-year-olds chases them away. Which seems to me to be backwards. Maybe it's that people [buying yearlings] think they have enough time to fix anything. I think they are looking for ghosts.”

Watching horses perform on the racetrack at a 2-year-old sale should provide buyers with more confidence than it generally seems to, according to Dunne.

“It amuses me when a horse goes up and works well enough and gallops out well enough to make them come down to see him and he comes out and he shows himself well and then they are going to come up with this huge problem that he might have,” Dunne said. “I don't know what they think we are that we would be able to mask something like that. At the end of the day, if you look at the scratch rate at 2-year-old sales, the ones that have problems are eliminated before they get to see them. And usually the ones that work good are the ones that end up being good horses. Again, you have to put the whole thing into context. How considerable can it be if they just performed at that level?”

Dunne stressed what he sees as the importance of potential buyers making decisions based on the findings of–and consultations with–their own veterinarians.

“I hate the vet reports,” Dunne said. “I hate showing the vet report because I feel like people, when they ask to see the vet report, are just looking for a reason not to go vet them. Whereas if they just go vet them, their veterinarian may not have an issue with the ink that's on the page. When we buy yearlings, I don't look at vet reports. If I like the horse well enough, I look at my vet's interpretation and I live or die by his opinion. I think everybody should do their own homework.”

‘It Feels Fantastic To Still Be Riding Regular Winners’: 52-Year-Old Joe Fanning Leads All British Jockeys

Yorkshire-based jockey Joe Fanning has been rolling back the years to lead the 2023 Flat Jockeys' Championship in Great Britain.

Currently in first place, Fanning is competing with some of the sports leading talent who fill the top 10 places of the leaderboard including former title race winners Oisin Murphy, Ryan Moore and last year's winner, William Buick.

This season, the 52-year-old has been prolific and at the top of his game. Having won 35 of his 157 rides, Fanning is currently operating at a 22 percent strike rate.

Murphy, who won the Flat Jockeys' Championship in 2019, 2020 and 2021, closely follows Fanning with 34 wins with a strike rate of 15 percent, with Hollie Doyle chasing the pair with 31 wins and a strike rate of 17 percent. Last year, Doyle finished joint second in the Championship, the highest placing of a woman rider in the sport ever.

Speaking on the Championship, Fanning said: “I am really pleased with how the season has started, it feels fantastic to still be riding regular winners. The horses are running well, it is still early days, but hopefully I can get a few big wins along the way too.

“There is a long way in the Championship to go yet, but I am pleased with how it is going, and it has been good to be a contender in the competitive title race. I try not to think about the Championship too much, I am just enjoying it.”

Fanning's career started in 1986 riding for Irish trainer Kevin Connolly. In 1988, he moved to England and began working for Tommy Fairhurst in Middleham, Yorkshire. Since 1996, Fanning has been primarily associated with trainer Mark Johnston to whom he has been a retained rider for. Since Charlie Johnston took over his father's (Mark) license in 2022, Fanning has remained retained rider, and in the last two weeks alone they have enjoyed six wins together.

Fanning has ridden more than 2,780 winners during his career and celebrated success at Group 1 level three times. His Group 1 wins include the Middle Park Stakes in 2016, aboard The Last Lion, the Prix – Royal Oak and the Ascot Gold Cup, both on star stayer, Subjectivist.

Fanning has been successful in the All-Weather Championships winning the competition twice, in 2009/10 and 2011/12. Fanning has also been one of only a handful of jockeys to have won a race at every racecourse in Great Britain.

Doyle, who enjoyed three impressive wins at Royal Ascot last week, said: “I've been pleased with how the season has started. Royal Ascot is a tough place to ride any winner, so it was brilliant to ride three winners there, particularly given they were all for my boss Archie Watson.

“Archie deserves huge credit for producing his horses in such brilliant form at such a big meeting. Having Group 1 calibre horses like Bradsell to look forward to for the remainder of the season is very exciting and I hope that there'll be further big days to come.”

The 2023 Flat Jockeys' Championship runs from May 6 – Oct. 21, 2023, and is one of horseracing's most prestigious titles, having been won by some of the biggest names in sport, including Lester Piggott, eleven-time Champion Jockey, and Frankie Dettori, three-time Champion Jockey.
