Zylkene Equine

Zylkene Equine is a natural product derived from the milk protein casein which has been developed to help horses and ponies overcome difficult or stressful situations.

Equine has not been associated with side effects such as sedation at the recommended daily intake,  is manufactured to human pharmaceutical standards (GMP) and is hypoallergenic preservative free and  lactose free.

Causes of stress in horses/ certain situations can be very stressful for some horses including: farrier visits, routine dentistry / teeth rasping, travelling, prolonged confinement e.g. box rest, weaning, 'breaking' / training,visiting or riding in a new environment and  new experiences e.g. meeting dogs a new structure in the yard exposure to new horses and people.

 How do horses react to stress?- Most horses will react instinctively in the face of perceived danger to escape or flee from the threat and protect themselves / if they are unable to get away they might respond with aggression.

What can I do for my horse? If you think your horse may be showing signs of stress first contact your veterinary surgeon who will be able to tell you if there is a medical reason for the behaviour/ your vet will also be able to discuss management options with you.

This should not be used in food producing animals.

It did not work for my horse

On 10 Dec 2016 Pet Drugs Online responded:
Thank you for your feed back, I am sorry to hear that the zylkene did not have the desired effect. Could I ask if this was to help with a short term problem such as clipping or travelling?
Kind regards

I have a mare who is on box rest after surgery, I was hoping it would help to stop her stressful behaviour especially box walking but I couldn't really see any improvement. She is the sort of mare who goes from calm to panic stations in a flash, Sedalin works but not much else. Any ideas!

On 10 Dec 2016 Pet Drugs Online responded:
that's a difficult one, I have a horse and now that the weather is bad he has to spend more time in the box. The sedalin is pretty good I have used this when I had a mare in with Laminitis and it worked really well. It might be worth having a prescription from the vet for the sedalin as I suspect it would be cheaper buying on line especially if this does the job. We do have an alternative calmer called Ecalm which has really good rating but I have not used this myself so cannot go by experience of the product. if I can be of any further help do let me know 


Used before and find it works with my horse




Har den lovede virkning. Hesten bliver afslappet men ikke sløv




Our horse is now so nice to be around since his introduction to Zylkene, what a marvellous product.


Very good
