Production of Equine Chorionic Gonadotropin (PMSG) serum glycoprotein with hormonal activity and sulfate chondroitin (sulfate polysaccharide for the treatment of arthrosis) generated a large amount of protein material that was wasted.

Today, this animal protein waste is transformed into amino acid foliage fertilizers, with urea, phosphorous or potassium according to each particular plant species.
