Not illustrated. 1917 edition. Excerpt: ...The same conception may be extended to fattening rations. Just as the net energy value of a feed for maintenance is measured by the loss of body energy which it prevents, so its net energy value for fattening is measured by the storage of body energy brought about. 449. Method of determination.--This conception, as well as the method of determining the net energy value for fattening, may be illustrated by the following respiration experiment by Kellner upon a mature ox, in which meadow hay was added to a mixed basal ration already sufficient to cause some gain. The second column of the table shows the metabolizable energy of the two rations, the third column the computed heat production, and the fourth the energy contained in the observed gain of protein and fat. Table 72.--Determination Of Net Energy Value For Fattening Each pound of hay added to the basal ration resulted in a gain of protein and fat containing 0.288 Therm of energy. This was its net energy value for fattening. A comparison with Table 37 in Chapter VIII (364), showing the results of a determination of the net energy value for maintenance, renders evident the identity of the method employed in the two cases, the only difference being that in one case the comparison between the two rations is made below the point of maintenance and in the other case above it. It is evident that in fattening, as in maintenance feeding, there is a considerable expenditure of energy consequent upon the consumption of feed, so that, only part of the metabolizable energy is actually stored up in the gain by the body. In the experiment given as an illustration, one pound of the hay contained 0.714 Therm of metabolizable energy, of which only 0.288 Therm or 40.7 per cent was recovered in the...
