ner for the corresponding ages on acount of the respiration calori- 

 meter experiments, covering about three months each year, during 

 which light rations were fed and little or no gain made. We may. 

 however, compare our results with those expected to be obtained 

 by the use of Kellner's standards by computing the average daily 

 rate of gain in the intermediate feeding periods. From Kellner's 

 figures, as given in Table Q, the expected gain per clay and head 

 may be computed as follows: 



Mret 



Between 4.5/2 and 9 months 

 Between 9 and 15 months 

 Between 15 and 21 months 



0.392 Kgs. 

 0.437 Kgs. 

 0.437 Kgs. 



Heet I {reeds 



0.392 Kgs. 

 0.564 Kgs. 

 0.437 Kgs. 



The actual average daily gains by our steers for the periods 

 covered by the rations of Table 7, as shown in Table 8. are repeated 

 in Table 10 in conjunction with what may be called the virtual age 

 of the animals, that is, the age exclusive of the respiration calori- 

 meter experiments. 



Table 10. Average Daily Gains in Live Weight. 



Pure-bred Steer Scrub vStecr 



On the average of the foregoing feeding periods, aggregating 

 17.7 months for the pure-bred steer and 16.6 months for the scrub, 

 the average daily gains were, respectively, 0.426 Kg. and 0.422 Kg. 

 The figures show clearly that the rate of gain during the feeding 

 periods, outside of the respiration calorimeter experiments on lim- 

 ited rations, was fully as great as that predicated by Kellner for sim- 

 ilar animals and would be very satisfactory in practice for animals 

 not being fattened. 



The rations shown in Table 7, computed to 1000 kilograms live 

 weight in direct proportion to the latter, are as follows:
