Your horse is in good shape because there is a lot of good stuff in Leiber Brewers’ Yeast

How does the brewers’ yeast work in your horse?
Leiber Brewers’ Yeast consists of 100% Saccharomyces cerevisiae, which is real brewers’ yeast sourced from breweries. Since breweries produce according to strict food guidelines, we can ensure the highest quality already in the raw material.

Due to the prebiotic and postbiotic effects of Leiber® Brewers’ Yeast, as well as its content of valuable ingredients such as B vitamins, amino acids and trace elements, you can improve any feed mixture and give your favourite everything what is necessary for a vital horse life.

Only the best for your horse.

Fit for winter
From the beginning of the autumn coat change, I feed all of my horses YeaFi. Foxes in particular often have sensitive skin and thin fur. With the YeaFi I can support her really well, even the picky mare really enjoys eating it and nothing is left behind. Thanks to the brewers' yeast, my horses have really shiny, good coats and can easily withstand the cold season. In addition, digestion is well supported and the transition from pasture to hay is not noticeable at all.

No more mallenders and better hooves for therapy horse Bim Bam

Bim Bam is a tinker, a cold-blooded mix. He has a comfortable and balanced character and is therefore a perfect therapy horse.

"Bim Bam always had problems with mallenders, lost his winter coat badly and muscled up only slowly. He also had problems with his hooves – he had hoof cancer on three hooves. With Leiber YeaFi® BT Bim Bam looks great, has no problems in the coat change and also no more mallenders. In the long term, the hoof quality has also improved."

With Leiber YeaFi® BT no problems with the change of coat.

In the past, Flux Blue had big problems with the change of coat. At a tournament, a horse breeder gave me the tip with Leiber YeaFi® BT. After about eight weeks of supplementary feeding, Flux Blue’s coat became shinier and the coat change was very smooth. The overall appearance of Flux Blue was also much more positive during the coat change – he was simply in a much better mood. After about ten weeks our farrier also noticed the positive effect of LeiberYeaFi® BT on the hoof horn. As a sport rider, I can only recommend Leiber.

Well through the cold season with Leiber YeaFi® BT

Successful breeder and himself riding up to Grand Prix (dressage), Paul Paessens combines his passions for breeding and sport in an ideal way.

"I use Leiber YeaFi® BT successfully in both breeding and riding stables. I particularly appreciate its use in the fall and winter months to support the digestive tract. I would like to emphasize the especially good consistency of faeces and the shiny coat."

Get a better grip on skin problems

"We fed LeiberYeaFi® in combination with Biolex® MB 40 for several months. Jos didn’t have such big open patches on her skin anymore. All in all, we got through the summer quite well and my Frieslein even took mane into the winter this year. I now feed Leiber YeaFi® permanently. In season, I add Biolex® MB 40 to it."
