WEIGHT 



482. Estimated averages. The foregoing results have 

 been plotted in Fig. 39 (479) for comparison with those 

 derived from the computations of i, regarding the rate, of 

 storage of energy. By drawing smooth curves through the 

 results for calves and for pigs, respectively, the following 

 approximate estimates of the average rate of gain of energy 

 by these two species have been obtained. No similar data 

 appear to be available for other species of farm animals. 

 The graph would seem to indicate that the results for cattle 

 may apply fairly well also to sheep, although no figures for the 

 latter species are recorded below 300 days old. Preliminary 

 computations on the basis of the live weights assumed by 

 Kellner for lambs at different ages seem to indicate higher 

 figures for the first six months, especially for animals of the 

 mutton breeds.
