The effect of dietary crude fiber levels on rhesus monkeys during quarantine.

A study was conducted to determine the effect of dietary crude fiber level on intestinal disorders in the feral rheusus monkey (Macaca mulatta) during the first 60 days of the quarantine period. Three experimental baked diets containing 2.4%, 7.0%, and 9.8% crude fiber and a commercially extruded diet containing 2.2% crude fiber were fed during the study. The morbidity rate of intestinal disorders at the 7% crude fiber level was 1.4%, which was significantly less (p less than 0.05) than the 11.1%, 12.5%, and 20.8% morbidity for the monkeys fed the diets containing 2.4%, 9.8%, and 2.2% crude fiber, respectively. Monkeys fed the 7% crude fiber diet had a mean number of treatment days for intestinal disorders per monkey of 0.014, which was significantly lower (p less than 0.05) than the 0.9, 0.5, and 1.4 days for those fed the 2.4%, 9.8%, and 2.2% fiber diets, respectively.
