In the present study the breath hydrogen excretion test was combined with the xylose absorption test in 4 normal horses and 9 clinical patients with chronic diarrhoea or chronic weight loss without diarrhoea. For the combined xylose absorption/hydrogen excretion test, the animals were starved overnight and given 0.5 g/kg/bwt xylose as a 10 solution by stomach tube the next morning. Blood samples were collected for plasma xylose analysis at 30 min intervals for 4 hours, and breath samples were taken at 30 min intervals for 8 hours. With the exception of one animal with granulomatous enteritis, the diseased horses showed only slight alterations in either peak concentrations or times to reach peak levels of plasma xylose. None of the healthy animals showed an increase in breath hydrogen production after xylose administration, whereas five of the diseased animals showed distinct increases. They also showed higher fasting breath hydrogen levels than healthy horses.
