Digestive disturbances- we all got em- including our faithful steeds-
Scientifically proven solutions?
1). Alfalfa Hay: Nadeu (2000) showed that only 50% of performance horses who were fed alfalfa hay vs 83.3% of horses who were not fed alfalfa presented with gastric ulcer lesions. It appears that the high calcium content in the alfalfa helps to inhibit gastric acid. When alfalfa is ingested, calcium absorption is increased, thus consequently, alfalfa hay could be used to prevent and heal gut lesions (Stowers, Waldron, Pryor, Hill & O'brien, 2013).
2). Yeast Addition: Since the welfare of digestive soundness is dependent on the balance of intestinal microbia, it is easy to conclude that microbial imbalances can cause colic or laminitis (Grimma, Pais & Julliand, 2018). Feeding high-grain diets have been associated with dehydration in the colon, which leads to colic and gastrointestinal distress (Blue & Wittkopp, 1981), and laminitis is a consequence of poor fiber fermentation, dehydration of digestive system, gaseous distention and colon displacement. Inflammation of the lamellar tissue in the hoof is a response to these negative factors, thus minimizing these factors by diminishing them and increasing the dosage of viable yeast to enhance the productivity of the digestive system would be far more beneficial.
3). Feeding and Time Management: About 60% of horse owners in the study constantly overfed their horses (Westendorf, Clusters, Williams, Joshua & Govindasamy, 2013). Feeding frequency also affects the gut microbiata, as generally, feeding horses three times a day vs two times a day or once a day significantly increases the protective microbials in the digestive system (Veneble, Fenton, Braner, Reddington, Halpin & Heitz, 2017).
4). Dietary Fatty Acid Supplementation: Diet is a factor that can predispose a horse to lower insulin sensitivity, and it is associated with the occurrence of laminitis, hence supplementation that would increase insulin sensitivity should be the priority to reduce the incidence of laminitis and metabolic syndrome. The direct supplementation of marine oil (algae and fish oil) increased the level of alpha-linoeic acid, arachidonic acid, docosahexaenoic acid, docosapentaenoic acid, and eicosapentanoic acid in the synovial fluid far more than traditional plant based (coconut, flax) concoctions (Ross-Jones, Hess, Rexford, Ahrens, Engle & Hansen, 2014).
5). Pectin: Crop by-products that are rich in pectin have high digestible energy, which will reach the cecum and provide the energy needed for performance and maintenance. Citrus and beet pulp contain high amounts of pectin, as well as other citrus families such as lemon, tangerine and pineapple (Frape, 2008). Good pectin fermentation occurs in the hindgut and thus promotes the viability and positive maintenance of the hindgut system, which is often neglected in the identification and treatment of debilitating ulcers.
Conclusion: Dietary characteristics are the main cause of digestive upset in equines. Feeding management, time of feeding, and dietary fatty acid supplementation will assist in avoiding metabolic disorders such as colic, ulceration and laminitis in the performance horse. Following these guidelines will reduce metabolic disorders that are triggered by depression of healthy gut bacteria and inconsistent feeding routines.
