PART IV 



COTTONSEED MEAL AS SUPPLEMENT TO RATION FOR 

 FATTENING LAMBS 



Part IV shows the effect of adding cottonseed meal to a ration 

 of shelled corn, clover hay, and corn silage for fattening lambs. 

 Both lots of lambs were started on oats and gradually changed to 

 corn as outlined in Part I. At the end of twelve days a pound of 

 cottonseed meal for twenty-five lambs was introduced into the ration 

 and increased until at the end of twenty days three pounds of cot- 

 tonseed meal and 21 pounds of corn were fed in Lot 7 as compared 

 with 24 pounds of corn in Lot 6. From this time forward both lots 

 of lambs were fed all the grain, hay, and silage they would consume, 

 the cottonseed meal being kept in the proportion of one pound to 

 seven pounds of corn. At no time during the experiment was there 

 any difference in the quantity of feed eaten between Lots 6 and 7. 

 The appetites of both lots of lambs were keen at all times. 



TABLE: IV. Effect of Adding Cottonseed Meal to a Ration of 



Shelled Corn, Clover Hay, and Corn Silage for Fattening 



Lambs, October 28, 1915 to February 5, 1916 



It will be noted in Table IV that there was no difference in 

 the feed consumed by the lambs. There was a very slight increase 

 in rate of gain by the use of the cottonseed meal. There was, how- 

 ever, an increase in cost of gain by the use of cottonseed meal, the 

 higher priced concentrate overbalancing the slight increase in rate 

 of gain. There was a much better finish secured on the lambs re- 

 ceiving cottonseed meal, Lot 7 being valued at $10.90 per hundred 

 pounds as compared with $10.30 per hundred pounds in Lot 6. The 

 profit per lamb was $1.31 per head when no cottonseed meal was 

 fed and $1.74 per head when cottonseed meal supplemented the 

 ration. This is in accord with previous trials showing that cotton- 

 seed meal had its greatest benefit in increasing the finish on the 

 lambs.
