Palatable and horse is enjoying it..early days to tell if it's making a difference but confident as with all feedmark products it does what is says on the tin!

I’ve used this in the past and it has been very effective. It smells wonderful and the horses love it. Now the weather is turning warmer I’m going to start using it so that it gets into their system before the flies arrive in force! Would recommend anyone to give it a go.

I’ve used fly formula for a number of years from spring to autumn. You can really see the benefit compared to those not on it

Blanca had Fly Formula in Spain, taken over in my suitcase… Worked a treat. Now living in Wales I’ve added it again to her feed to prepare in advance for the fly/midges season to help her to again build up immunity from needing to scratch her mane off!

I think this is a good supplement, doesn't keep all the flies away of course but I do think my ponies are less bothered by them than the others on the yard.

Have used this for over 12 months it helped with flys in the summer. It also smells so nice it encourages my fussy mare to eat her additives. I have been very pleased with this product.

I have used fly formula for several years now and it has definitely made a difference to my horse that has a terrible reaction to fly bites . It doesn't eliminate the problem completely but has made the problem much easier to manage . I tried him for a short period without and his reactions became much worse so put him back on it and things improved immediately which is why I gave it 5 stars

Fly Formula has changed our lives over the last 2 summers, as the ponies have been able to live without constant itching. Almost no scratching and mutual grooming which resulted both used to result in skin sores.

I have used this product now for 5 years on both of my horses. One horse just through the spring/summer season and the other all year round as it helps with skin allergies too. If I take him off the fly formula for a rest his lumps come back within 2 weeks and if I start giving it again it clears up within 2 weeks. So I would say I never run out of this product

Excellent service. My mare ate it without any problem but very sadly flies still landing on her. I have had to resort to using a Fly spray.

Excellent product to help with preventing fly bites during the summer.
(Does have garlic in it which when given gradually my horses ate without any issues).Used in conjunction with ‘equidermis’ my horses has pretty much had protection from fly bites compared to previous years…feel this used with ‘equidermis’ is an excellent supplement to try….would highly recommend.

My gelding ate it straight away. My mare took a week to get used to it. But both enjoy it now and although only started them on it a month ago I can see a difference. I will be keeping this in their feed all year going forward

Have been using this since late spring this year. Flies have definitely been less on both my horses so far, now mid summer. The total recommended amount hasn't been used as they only need to be fed once a day & I find the full dose would be too much for what else I am feeding, one has just a pellet balancer, the other a joint supplement. Will continue to use until autumn.

Only been feeding it for a few weeks but he seems to be less itchy, maybe a bit early to tell if it is helping to keep the flies away. It smells great and he eats it in his feed with no issues.

Flies this year are horrendous here. The horses have flies on them but less than those not on Fly Formula. It works but nothing is ever going to totally eliminate flies.

The best product I've found to help my sweet itch mare, she has it all year round as she's rug free over winter.
Being a veteran at 28 she also has feedmarks best flex ha, still as active as she was 15 years ago, no stiffness, no clicky joints.
