Document Summary

Describe the primary reason, related to its structure, that makes cellulose indigestible by animals without microbial fermentation in their guts: cellulose is made up of beta-links. What is the primary reason for nutrient analyses of forages: the primary reason for nutrient analysis is to predict animal performance. We want to match the forage to the animal"s metabolism it best suits so we can get the best performance and thus product from it. Describe the individual components and partitioning of the plant cell wall and how they are related (correlated) to nutrition of the ruminant: there are soluble digests such as starch. Starch is made up of amylose that can be degraded by amylase and provide energy to the cow: there are insoluble parts of the plant that can"t be digested. These provide effective fiber and stimulate more chewing of the cow: there is hemicellulose which is made up of mostly xylose.
