The results of these trials are typical in showing the effect 

 of adding a high protein concentrate to a ration in which corn is 

 fed with a roughage containing a low per cent, of protein. The 

 most noticeable effect was on the appetites of the lambs. The lambs 

 fed the ration not containing supplement had delicate appetites. It 

 was difficult at all times to keep them on feed. The longer they 

 continued on feed, the more difficult it became to prevent their 

 going "off feed." The lambs receiving cottonseed meal, on the other 

 hand, ate grain well at all times although they did not relish their 

 hay. Table VI shows that in all trials, the grain consumption was 

 larger when a supplement was fed, and the average of three trials 

 shows approximately 15 per cent, increase in the quantity of grain 

 eaten as well as a slight increase in the quantity of hay eaten, due 

 to the addition of cottonseed meal. 



The rate of gain is a very good indication of the feeding value 

 of the two rations. In the first trial, the lambs fed corn and timothy 

 hay gained 17.8 pounds per head and those fed cottonseed ireal in 

 addition to corn gained 26.5 pounds per head. In the second trial 

 the lambs fed the former ration gained 10.3 pounds per head and 

 those on the latter gained 14.2 pounds. The gains made in the last 

 trial were 12.4 pounds and 15.6 pounds per head respectively. The 

 average gain per lamb was increased in the average of three trials, 

 from 13.5 pounds to 18.7 pounds or approximately 39 per cent., by 

 the addition of cottonseed meal. The cost of gains was greatly 

 decreased by the addition of cottonseed meal to the ration. The 

 grain required to make a pound of gain was decreased from 5.29 

 pounds to 4.36 pounds by the addition of the nitrogenous concen- 

 trate, while the hay required per pound gain was decreased from 

 4.84 pounds to 3.66 pounds. This saving of feed resulted in a de- 

 crease in cost of gain varying from $1.05 per cwt. gain in the first 

 trial to $2.18 per cwt. gain in the second trial. The average saving 

 on the actual cost of gain was $1.60 per hundred pounds. When 

 timothy hay is figured at a normal price of $12.00 per ton and clover 

 hay of $10.00 per ton there would be a saving on each hundred 

 pounds of gain of $1.05 when corn is 40 cents per bushel; $1.28 

 when corn is 50 cents per bushel; and $1.51 when corn is worth 

 60 cents per 'bushel. The lambs fed the unsupplemented ration 

 were in no case in very much better than feeder condition when the 

 trials ended. The selling value of the lambs was increased 35 cents 

 per cwt. in the first trial and 32^ cents in the last trial by the addi- 

 tion of the cottonseed meal.
