Sliced sugar beets were added to the coru and alfalfa ration of lot 10. 

 The daily gain was 0.3G6 lb. per head. Compared with the results of lot 1, 

 2.98 Ib.s. of beets took the place of 0.5 lb. of corn and 0.38 lb. of alfalfa in 

 producing a pound of gain and reduced the cost 0.08 ct. if the beets are 

 valued at $4 a ton. 



Lot 11 (corn and alfalfa hay) was fed in the open, whereas the other lots 

 were all under .shelter. The coru consumption per unit gain was the same as in 

 lot 1 ; the alfalfa consumption was 0.14 lb, less. 



Lot 8 (self feeder) made an average daily gain of 0.5 lb. per head for the 

 40 days of the test and consumed 2.65 lbs. of corn, 2.09 lbs. of linseed meal, 

 and 0.7 lb. of prairie hay per pound of gain, at a cost of 7.34 ets. The charge 

 for prairie hay is not indicated. Unless a high finish is required in a short 

 time, this method of feeding is not recommended. 



A table is included showing the changes in cost of gains of each lot with 

 changes in the prices of the feeding stuffs used. ' 



Ninety-five-day lamb feeding- experiment, November 23, 1916, to Febru- 

 ary 25, 1917 {Bui. Nehr. Bd. Agr., No. 245 (1918), pp. 355-557 ) .—Eight lots of 

 27 Wyoming lambs and one of 2G were fed at the Nebraska Experiment Sta- 

 tion. Lots numbered 1 to 8 were intended as duplicates of the lots bearing 

 corresponding numbers in the preceding winter's experiment noted above. 

 A selling price was assigned to each lot according to the finish. The results 

 from the tests of limited corn feeding and from the comparisons of protein 

 supplements may be summarized as follows:

The following prices were charged : Corn 84 cts. a bushel, and alfalfa $10, 

 linseed meal $45, cottonseed meal $45, and cold-pressed cottonseed cake $40 

 a ton. 



The amounts of alfalfa hay consumed were about equal in lots 1, 2, and 3, 

 and it is pointed out that the gains wei'e in proportion to the quantity of 

 corn eaten. 



Lot 4, which received silage in additicni to corn and alfalfa, gained at the 

 rate of 0.377 lb. per head per day and consumed 3.08 lbs. of silage per pound 

 of gain. This quantity of silage effected a reduction of 0.7 lb. in the corn 

 and 0.36 lb. in the alfalfa required for a pound of gain if lot 1 is taken as 

 the check. With silage charged at $5 a ton, the cost of a pound of gain was 

 6.18 cts. This lot sold for 14.1 cts. a pound and yielded a profit of $3.70 a 

 head.
