Dietary risk factors and colonic pH and mineral concentrations in horses with enterolithiasis (2)

Published: 2004-12-21

Brief content of the article
These authors performed a study to indentify dietary and environmental risk factors for enterolithiasis in horses in California. It was also studied whether colonic ingesta analyses differed between horses with and without enteroliths. the authors compared 43 horses with enteroliths with 19 horses with surgical colic attributable to non-strangulating obstruction of the colon without enteroliths. The authors observed that the mean pH of the colonic contents of horses with enterolihtiasis was significantly higher than for control horses. Further, a lower percent dry matter content in colonic faecal samples and a higher mean mineral concentration was observed in horses with enterolithiasis. The authors also observed that horses with enteroliths were fed alfalfa rich diets (> 70% alfalfa in the diet) and were less likely to have daily acces to pasture compared to horses without enteroliths. The results of this study suggest that decreasing alfalfa consumption and allowing dailey access to pasture grass may the risk for enteroliths.
