Document Summary

The potential energy of transformation is measured by calorimetry. Gives reference to the potential energy of food. Can be used to measure heat production from animals: direct calorimetry measures the amount of heat produced, indirect calorimetry utilizes measurements of gases consumed (o2) and produced (co2) to calculate heat production. The bomb calorimeter determines the total potential (determined as heat) It does (cid:374)ot disti(cid:374)guish (cid:271)et(cid:449)ee(cid:374) e(cid:374)e(cid:396)g(cid:455) that"s a(cid:448)aila(cid:271)le to the animal for work or that which is lost in the various processes of digestion, absorption, and metabolism. Gross energy (ge) is the heat of combustion: energy release when a substance is ignited: depends on the contribution of cho, fat, and protein to the feedstuff. If the composition of feedstuff is known we can calculate the caloric content of the diet using the estimates provided for fat, carbs, and protein. It does not consider the digestibility of the diet: it does not provide an index of the nutritional value of the feedstuff.
