Lactobacillus is the most commonly used bacterial species (Swyers et al. 2008). A study conducted by Al Jassim et al. recorded that several species of Lactobacillus were located throughout the equine gastrointestinal tract. This concludes that these microbes have the ability to adapt to pH changes and survive in different environments. L. mucosae and L. salivarius were found to be the most abundant. L. salivarius, specifically, was cultured from the stomach, colon, and rectum, suggesting its high survival rate in acidic environments (Al Jassim et al. 2005). While probiotics are supposed to be the “good” bacteria, there are certain strains of Lactobacillus and Bifidobacterium that are considered to be detrimental to the horse 's health. A study done with neonatal foals in 2005 used Lactobacillus pentosus WE7 to prevent diarrhea. Weese and Rousseau reported that the bacterial strain failed to do so. In fact, it managed to make the diarrhea worse and cause other complications. Mixes, such as the one done by Yuyama, are able to prevent diarrhea and promote growth in foals. The strains that were used were Lactobacillus salivarius, Lactobacillus reuteri, Lactobacillus crispatus, Lactobacillus johnsii, and Lactobacillus equi. (Endo et al. 2007). When horses intake too much starch, lactic acid builds up from the Lactobacillus and Streptococcus microbes and the amount of fermentation taking place. Bifidobacterium has showed to be sensitive to changes in the environment in some…
