| Popis: | Seventy-two adult cheetahs were evaluated for the degree of gastritis by endoscopic biopsy and for renal disease by serum creatinine. Cheetahs free of Grade 3 gastritis and renal disease were placed on Trial A; remaining cheetahs were placed on Trial B, which ran concurrently. All cheetahs were monitored for 4 years. Cheetahs exited Trial A and entered Trial B if they developed Grade 3 gastritis or renal disease. Cheetahs exited Trial B if they developed clinical gastritis or renal disease that required a dietary change or aggressive medical therapy or died owing to either disease. Cheetahs on Trial A were fed either a supplemented meat diet (N = 26) or commercial cat food (N = 22). Cheetahs on Trial B were fed either the same meat diet (N = 28) or a commercial dry cat food formulated for renal disease (N = 16). Cheetahs fed meat on Trial A had a daily hazard of developing Grade 3 gastritis 2.21 times higher (95% CI 0.95-5.15) than cheetahs fed commercial cat food. This hazard was not statistically significant (P = 0.07). Mean gastritis scores were not significantly different between the two groups. Cheetahs fed commercial cat food in both Trials had lower serum urea levels and higher creatinine levels than those fed meat. Evidence for the effect of diet in cheetahs with gastritis and/or renal disease (Trial B) was inconclusive. The number of cheetahs dying of gastritis or renal disease at the facility has dropped markedly since the study began. These results indicate that diet may play an important role in the incidence of Grade 3 gastritis and that dietary and/or therapeutic management of gastritis may reduce mortality owing to gastritis and renal disease in captive cheetahs. |
