Non-medicinal food additive for animals, supplemented food containing same and method for improving animal growth
This invention relates to a non-medical food additive that is an animal growth promoter containing 99% pure zeolite partially or totally exchanged with a C m+ cation (in other words a synthetic zeolite) with the general formula I below: 1 m yC m + ( 1 - y ) 1 n M n + AlO 2 x SiO 2 in which x is greater than 1 and advantageously between 1 and 15; M n+ represents an alkaline or alkaline earth exchangeable ion, advantageously Na + , K + , Ca 2+ or Li + ; n is between 1 and 2; y is the exchange rate and is between 0.001 and 1; C m+ is a metallic cation chosen from among copper Cu 2+ , silver Ag + or zinc Zn 2+ ; m is between 1 and 2. It also relates to an additive premix and a supplemented food containing it and a method of improving the growth of animals.
