366 EXPERIMENT STATION BECOED. [Vol. 37 



The authors interpret the results as indicating that " the common Pennsyl- 

 vania ration of corn-and-cob meal, wheat bran, mixed hay, and corn stover, fed 

 during the entire 140-day period, did not improve the finish nor value of the 

 cattle, and it proved to be more expensive than any of the rations which con- 

 tained silage as roughage only, or roughage and cottonseed meal in the e;irly 

 part of the feeding period, and whose combinations were supplemented with 

 corn in the latter part ; also when corn silage and cottonseed meal were fed 

 during the entire period. Corn silage proved to be the most desirable roughage. 

 A ration with a limited amount of corn silage supplemented with mixed hay 

 was not so economical nor so satisfactory a roughage ration as one containing 

 silage as a sole roughage. . . . 



"A ration of corn silage and alfalfa hay as a source of protein during the first 

 56 days of the feeding period, supplemented with corn the balance of a 140-day 

 period, was the cheapest daily ration, but it did not produce sufficient gains 

 and finish. 



" Wheat bran at $25 per ton is not so desirable a .source of protein as cotton- 

 seed meal at .$32.0(5 per ton, or alfalfa hay at $15 per ton. 



"The results from comparing alfalfa hay and cottonseed meal as a source 

 of protein, in a ration of corn silage as roughage, supplemented with corn dur- 

 ing the last three months of a five-month feeiling i)eriod. indicate that cotton- 

 seed meal is a superior source of protein on account of proilucing a more rapid 

 finish on the cattle, which will thus command a higlier selling price on the 

 market. 



"The margin necessary between the buying and selling prices is rwlucetl by 

 hogs following cattle in the feoil lots, especially when whole grain is fe«l. 



" Corn silage fe<l to the limit of appetite and .supplemente<l with 2.5 lbs. of 

 cottonseetl meal per head daily the first three months, and 3.5 lbs. per head 

 daily the last two months, proved to be the most economical ration. Cattle 

 thus fed were value<l within 5 cts. per 100 lbs. of cattle receiving, during 

 the last 84 days, corn in addition to silage and cottonseed meal. 



" The returns per steer, after paying for the feed consume«l, were In direct 

 proportion to the amount of silage consumeil. The lots receiving the largest 

 amount of silage alone and silage supplemented with cottonseed meal gave the 

 best returns per steer. 



" Five lbs. of alfalfa hay per day. in addition to 2.5 lbs. of cottonseed meal as 

 a source of protein, was not found economical. . . . 



" The manure produced was tlguretl as being sufficient to pay for the betiding 

 and labor required to take care of the cattle." 



Feeding baby beeves, .T. C. Burns (Texas Sta. But. 198 {1916), pp. 5-2/. figs. 

 8). — The objects of the experiments reported were to study the production of 

 baby beef in general ; to compare cottonseed meal, cold pressed cottonseed, and 

 peanut meal for supplementing a ration coniposetl of ground mlio maize, corn, 

 or sorghum silage, and Sudan grass hay ; and to compare the feeding values of 

 Sudan grass hay and cottonseed hulls. 



Four lots of 12 high-grade Aberdeen-Angus steer calves were used. Before 

 the experiment was begun the calves were fed together on a ration consisting 

 of cold pressed cottonseed, ground milo maize, corn silage, and Sudan grass 

 hay. In the experiment proper lot 1 was fed the above ration ; lot 2, peanut 

 meal, ground milo maize, corn silage, and Sudan gra.ss hay ; lot 3, cold pressed 

 cottonseed, ground milo maize, corn silage, and Sudan grass hay ; and lot 4, 

 cottonseed meal, ground milo maize, corn silage, and cottonseetl hulls. The 

 actual feeding experiment covered a period of 201 days. Sorghum silage re- 

 placed corn silage for the last 51 days of the test and a small quantity of
