I was 24.8 bushels of corn, 41.6 pounds of cottonseed meal and 

 2,593.4 pounds of corn silage. In Lot II it was 13.5 bushels of 

 corn, 41.6 pounds of cottonseed meal and 4,365.8 pounds of corn sil- 

 age. As the gains made by each lot were almost identical, it may be 

 said that 1,772.4 pounds of corn silage replaced 792.92 pounds of 

 ear corn, or a ton of silage would replace 894.6 pounds of ear corn, 

 which at 7oc per bushel would give the silage a replacement value 

 of $8.94 when substituted for ear corn under conditions prevailing 

 in this test. 



TABLE V. Feed and Air-Dry Matter Required to Produce a 

 Pound of Increase in Live Weight. 



Table V shows that the amount of feed and dry matter re- 

 quired to produce a pound of gain increases as the feeding period 

 advances even though the ration is made more concentrated and 

 has a higher energy value. This is probably due to the difference 

 in the character of the gain. In the early stages there is a filling 

 up of muscular tissue with water and proteids, but during the fin- 

 ishing period the gain is for the most part fat, which has a higher 

 energy value than any other substance in the body. The results 

 indicate that the heavier silage ration was more efficient in pro- 

 ducing gain, though the general appearance of the cattle indicated 

 that Lot I was fatter at the close of the test, hence the difference 

 in efficiency was probably due to a difference in the kind of mater- 

 ial put on the carcass. Neither of the two lots were sufficiently 

 finished to command the attention of buyers who look for fancy 

 beef, but were classified as "handy-weight" steers such as are in 

 strong demand at all times. A higher finish would have required 

 a much longer feeding period and a much more expensive ration. 



Shipment and Sale of Cattle. 



The cattle were loaded on cars at State College Saturday morn- 

 ing, April 6, 1912, and shipped to Pittsburgh where they were sold 

 as one lot on Monday, April 8, 1912. The following table gives 

 in detail the expenses incurred in shipment.
