The results are fully tabulated in the bulletin, and from the.'^^o the fol- 

 lowing statement, showing" tlie average per animal for each lot, is taken. 

 In the caleuhitions of the cost of food, corn meal, whole com, and bran 

 were eacli reckoned at 820 per ton, hay at ^U), and silage at $2.50. and 

 no allowance was made for the value of tlie manure.

Comparing, first, the silage and hay it would seem from the above that 

 in this tii;il those animals r«'cei\ing silage consuined the largest amount 

 of thy matter and made a larger gain in live weight than those receiv- 

 ing hay instead of silage; the silage, however, contained a larij'e am<»nnt 

 of water, Avhich intn»duces a factor dilhcult to make allowance for. The 

 extra amount <»!' water taken into the body may have increa.sed the 

 ai>iiarent gain, although there was a continuous inerease in weight to the 

 end of the experiment, as will be seen from the following averages:

 Third 3 weeks . 



The sudden falling off in the average amount of gain after the first (! 

 weeks of feeding is noticeable both where silage and where hay were 

 fed. The average cost of food per pound of increase was 8.2 cents with 

 silage and 11.2 cents with hay. 



''It would seem that a variation so great as tliis w(»uld not all be 

 accounted for by indi\ idnal ])eculiarities, but rather by the fact that 

 silage is ver\ economical tt> give in moderate quantities to fattening 

 animals."'' 



As between corn meal and whole corn the data indicate the former to 

 be the most eccmomical, for while the average cost of food per jiound of 

 increase in tlu* lots receiving corn meal was 7.35 and O.-'io cents resjuct- 

 ively, it, was \).'.\ and 17.5 cents with those receiving whole corn inst«'ad.
