In order to provide high yielding cows with the optimum level of amino acids, protected amino acids have to fulfil two important factors: rumen stability and intestinal availability. Fatrix Methionine achieves a rumen-stability of 75.5pc at a passage rate of 8pc per hour. The intestinal availability of methionine reaching 87.7pc is considered very high. The fat coating is almost completely digested, which therefore means that the largest proportion of methionine is digested and made available for the animal. Palital offers under the Fatrix range the products Fatrix Methionine, Fatrix Choline, Fatrix Lysine and Fatrix CLA.
