GAINPRO® (bambermycins) is a performance enhancing antibiotic intended and available solely for use in animal nutrition. GAINPRO is predominately effective against gram-positive pathogenic bacteria; however it does not have significant action against lactobacillus, bifidobacterium, and other protective bacteria. Its effect is to inhibit the synthesis of the bacterial cell wall.
