Probiotics (lactic acid bacteria) should be mixed into feed instead of being added directly to water to ensure the viability of the bacterial colonies and achieve targeted colonization benefits. When added directly to water, probiotics are rapidly diluted by water flow, degraded by UV exposure, and adsorbed by filter media—studies show that over 90% of the bacteria can be lost within two hours. Moreover, free-floating probiotics in the water are difficult for koi to ingest effectively.
When mixed into feed, the bacteria are delivered directly into the intestinal tract along with the food, where they can quickly multiply within the digestive system. This significantly enhances koi's ability to break down dietary proteins and suppresses the growth of harmful gut bacteria.
Additionally, moist feed particles form a protective layer that helps shield the probiotics from premature inactivation by stomach acid, ensuring that sufficient viable bacteria reach the intestines to perform their functions. This method also prevents the waste of bacterial supplements and avoids potential water pollution caused by excessive bacterial additives in the pond environment.
Furthermore, feed-based delivery allows for precise dosing, better integration with the koi's feeding rhythm, and sustained release of probiotics during digestion—maximizing both efficacy and cost-effectiveness in supporting koi gut health and overall vitality.
