Weese and Martin did a study in 2011 testing commercial probiotic supplements. They found that many of the products did not meet standards printed on the label. It has also been found that some commercial probiotics that claim to be beneficial, but do not contain microorganisms that are located within the horse. If this is the case, the microbes stand little to no chance of survival or colonization (Mirlohi et al. 2009). Currently in the United States, there are not any approved equine probiotics because they are classified as drugs. To be approved and considered a drug, it must meet the requirement set by the Food and Drug Authority (FDA). Labeling the product accurately is all that is required. An alternative classification is ‘generally …show more content…

Not enough studies have been done to confirm if feces samples can be a valid representation of the large intestine microbial population. There are vast changes that occur from the stomach to the rectum. This leads to the conclusion that the microbes would also change along the digestive tract. (Dougal et al 2012). Schoster et al. reports that in order to have a positive representation from fecal samples, the microbes must have shed when the sampling took place. It is unknown how often shedding occurs or how often fecal samples should be taken in order to determine the amount of shedding. This pertains to probiotics as well (Schoster et al. 2014). In opposition to those studies, other studies have shown that fecal samples can be a satisfying representation (Costa and Weese 2012). Dougal et al. reported that the feces most closely represented the microbes from the colon, but not the cecum. In this case, feces may not be appropriate to use when deciphering diseases where the cecum needs to be studied. Schoster et al. found that feces best represented the microbes located in the cecum (Schoster et al. 2013). In 2010, Sadet-Bourgeteau et al. conducted a study that showed there was a similarity between the two areas, suggesting that the microbial population does not abruptly change, but changes slowly (Dougal et al. 2012). With so many factors that can change a result, it is difficult to determine the best
