ANSC 1001 Chapter Notes - Chapter 6A: Bile Acid, Hemicellulose, Maltase
Document Summary
Microbial protein produced in large intestine is wasted: digestive process of hind-gut fermenters. Proteins broken down into peptides by proteases in the stomach. Peptides broken into amino acids and absorbed in the small intestine. Broken down by bile salts and lipases into fatty acids and absorbed in the small intestine. Broken into maltose by amylase in the mouth. + either goes straight to alpha-vfas to be digested in the large intestines or is broken into glucose by amylase and maltase in the small intestine, where the glucose is absorbed. Broken into beta-vfas in the large intestine and absorbed. Factors influencing digestibility: nutrient content, fiber content, rate of passage, roughage: concentrate ratio, feed intake/volume, feed-processing. + metabolic energy converted into urinary/gaseous energy or net energy. Net energy converted into heat energy and production/maintenance energy. Dietary fat: triglycerides (3 fatty acids + glycerol) Simple lipids esters of fatty acids/glycerol; waxes. One or more amino acids linked by peptide bonds.
