ANSC 1111 Lecture Notes - Lecture 14: Calorimeter, Colorimetry, Leat
Document Summary
Total gross energy of feed is determined using a bomb calorimeter. Heat of fermentation is higher in a ruminant animal than a monogastric animal. Net energy components include exercise, growth, lactation, maintenance, and. Increment is by own bacterial cells basal metabolism. Differentiated by surface area and not body size. Heat production expressed per kg,bw^0. 75 = metabolic body size. Accounting for differences in skin folds, fluffiness, etc. Oxygen consumption is equated to heat production. In the catabolic reactions that create atp using oxygen, heat is produced. If the body has enough nutrients, it can handle all three (basal metabolism, maintenance requirement, and lactation), but if it does not have enough, then it cannot. Amount of energy required by the body at rest. This energy is used for smooth muscle contractions, breathing, heart contractions, cellular function, brain function, etc. Women have a lower metabolic rate than men do. Energy required for normal movement (includes digestion and absorption) above basal metabolism.
