NettetAbstract Because small ruminants (<15 kg) have a high ratio of metabolic rate to fermentation capacity, they are expected to select and require low-fiber, nutrient-dense concentrate diets. However, recent studies suggest that small ruminants may not be as limited in their digestive capacity as previously thought. In this study, we exam- NettetPlant cell walls are constructed mainly of cellulose, a material that the digestive enzymes of higher animals are unable to digest or disrupt. Because of this, even the nutritious contents of plant cells are not fully available for digestion. As an evolutionary response to this problem, many leaf eaters, or herbivores, have developed a pouch at the anterior …
