Innovative alternative to antimicrobial GPs

摘要

Growth promoters with an antimicrobial activity, when mixed into the feed, have been used for decades as they no doubt contributed substantially in increasing poultry, swine and cattle production output and efficiency. Some of them additionally helpedto reduce clinical complaints in animal production, though used and regulated at sub-therapeutic dosage regime levels, as compared to veterinary products. Antimicrobial growth promoters act on the bacterial intestinal flora of animals, modifying their metabolisation pattern in a way that nutrient digestibility is improved.
