SOLUBILIZAÇÃO DO NITROGÊNIO EM DIFERENTES PRODUTOS A BASE DE UREIA

Urea is a food additive that is part of non-protein nitrogen compounds and is widely used in the diet of cattle, especially during periods of drought, when the protein level of pastures is low. Due to its high solubility, together with errors during use, can lead to intoxication in animals. In order to circumvent this problem, methods and products that control urea solubility have been developed. Waxes are hydrophobic, malleable and inert products which are desirable characteristics for a coating material. Therefore, the present work aimed to evaluate the controlled release of nitrogen from two new products (developed in UFMS) based on urea coated with wax and compare with that of commercial products (Amireia® and Optigen®). The results showed that the products developed are efficient in the control of the nitrogen release, proving the reduction in the solubility of urea conferred by the waxes.
