Document Summary

Both species are simple-stomached, non-ruminant herbivores whose natural diet consists of primarily green forages but readily consume grains and hay. Both species efficiently digest non-structural carbohydrates (starch, sugars) and plant proteins in the stomach and small intestine. Both have capacity for substantial hindgut fermentation of structural carbohydrates (although anatomical sites differ) Site of fermentation: rabbits are primarily cecal fermenters, horses are colonic fermenters. Horses: requirements usually expressed in terms of de, requirements for pregnancy, lactation, and growth are estimated according to principle covered in previous lectures. Lecture 36: comparative nutrition horses and rabbits (cid:1) (cid:1) Rabbits: requirements also usually expressed in terms of de, ncr recommendations for energy and specific nutrients are outdated and need revision. Although both species have hindgut fermentation, efficiency of fiber digestion is greater in the horse than in the rabbit. Horses fed high forage diets probably make extensive use of.
