Weights of digestive organs, caecal metabolites and fermentation stoichiometry in coypus and rabbits

Original language description

Coypus and rabbits fed the same granulated feed ad libitum were slaughtered, digestive organs weighed and their contents analyzed. The caecum was the largest digestive organ in both animal species. Its weight averaged 170 g in coypus and 157 g in rabbits. Gastric acidity and caecal and colonic dry matter concentrations were significantly higher in rabbits. The volatile fatty acids (VFA) and ammonia concentrations in the caecal contents of coypus and rabbits were similar. Molar percentages of acetate andpropionate, however, were significantly higher and percentage of butyrate lower in caecal VFA of coypus than in rabbits. Caecal microorganism of coypus produced more propionate and methane, and less butyrate and valerate than caecal microbes of rabbits.Caecal fermentation pattern in these herbivore species differed more than other parameters investigated.
