TDN Rocketsâ¢ are a stabilized source of lactic acid bacteria including Lactobacillus acidophilus DDS-1, inulin, yeast and certain vitamins in a fast dissolving capsule for quick absorption. Administer to cattle during ration changes, freshening, depressed appetite, shipping, weather changes and following antibiotic treatment. Benefits TDN Rocketsâ¢ are a fast dissolving capsule allowing for ease of application and quick absorption. The capsules contain stabilized direct fed microbials, inulin, yeast and vitamins required for maintaining appetite during times of stress in livestock. How it works: Direct fed microbials have been shown to help maintain normal appetite. Since one direct fed microbial alone cannot provide all the required health benefits, TDN Rocketsâ¢ contains four species of live naturally occurring lactic acid bacteria including three species of Lactobacillus (acidophilus, plantarum, casei) along with Enterococcus faecium. Live Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus casei and Enterococcus faecium all ferment lactose into lactic acid. As direct fed microbials, they promote the breakdown and assimilation of nutrients while helping to maintain proper gut flora. Inulin helps support the direct fed microbials. Vitamins C and E provide antioxidant support which in turn scavenge for damaging free radicals.
