Hindgut fermentations in nonavian species.
A brief comparative discussion of the hindgut of insects, mammals, fishes, and reptiles includes morphology of the hindgut, general appearance, content, materials fermented, fermentation products, microorganisms involved, and value of the hindgut to the host animal. The problems faced by small animals in securing adequate energy from a hindgut fermentation to be of value to the animal are presented. It is suggested that our present analytical methods are not adequate and that new approaches to analyzing the hindgut fermentation value should be investigated, such as using fecal bacterial mass as an index. It is also suggested that experimental and commercial feeding should be designed so that herbivores are not converted to omnivores.
