What is this product used for: Probios Horse Treats are a lactose-free treat that are a source of direct fed microbials that promote digestion and a healthy body. It also helps maintain joint function. Benefits: Probios Horse Treat Hip and Joint are a source of direct fed microbials in a lactose-free treat format. The direct fed microbials help maintain proper gut flora and help support gut absorption. The treats also help maintain joint function. Probios Horse Treats Hip and Joint are for all breeds and all horses. The treats are apple flavored, a flavor horses love. How it works:Since one direct fed microbial alone cannot provide all the required health benefits, Probios Horse treats contains two species of live Bacillus that can survive the treat manufacturing process: Bacillus subtilis and Bacillus licheniformis. As direct fed microbials, they promote breakdown and assimilation of nutrients while helping to maintain proper gut flora. Glucosamine and chondroitin help maintain normal cartilage and joint function.
