    From Kerry Brown, Edinburgh:


    "Hi John, As promised, I wanted to email you to let you know about my experience with Equibuilda.

    I purchased a Belgian warmblood last September. When he came to me he was quite lean, very unfit and completely without muscle tone. Although he grew fitter and more toned as the winter progressed, he became pretty thin.  In spite of significantly increasing his feed and giving him ad lib haylage, his condition did not improve.


    I began giving him Equibuilda at the end of January and within 3 weeks I started to receive comments on the improvement in his condition. He now (mid April) looks glorious- round and happy with an incredibly silky coat and the compliments continue. He is a flea bitten grey but has a shine to his coat that a chestnut would be proud of! I have just purchased a second horse who will also coming to me thin and unfit. I will be starting him on Equibuilda from day one. Many thanks!"
