PART VI 



22. Lambs fed in a well ventilated barn ate the same amount 

 of feed and made the same gains in weight as those fed in an open 

 shed. 



23. Lambs fed in the barn were of softer flesh and were 

 valued 10 cents per hundred pounds less than those fed in an open 

 shed. 



24. The profit per lamb was 94 cents per head in a barn as 

 compared with $1.04 per head in an open shed. 



OBJECT 



The object of this work was to obtain additional information 

 m the comparative feeding value of the more common roughages of 

 the farm and on the advisability of using some concentrated com- 

 mercial feeding stuff for fattening lambs. This includes a com- 

 parison of clover hay and corn silage alone and in combination as 

 roughage for fattening lambs; the value of corn silage alone as 

 roughage and in combination with dry roughage for fattening 

 lambs ; a comparison of the feeding value of clover hay and alfalfa 

 hay for fattening lambs; the value of cottonseed meal for supple- 

 menting rations of corn, clover hay, and corn silage; and the com- 

 parative value of oats and corn for fattening lambs. The influence 

 of shelter such as an open shed or barn upon fattening lambs is 

 ilso shown. 



PLAN 



The plan of the work was to secure strong, vigorous western 

 lambs and discard the smallest and any extremely large ones in 

 order to secure a flock as uniform as possible. This selected flock 

 was divided into nine lots of twenty-five lambs each. All lots were 

 as nearly uniform as possible as to si^e, condition, quality, thrift, 

 and breeding. Eight of the nine lots were placed in an open shed 

 and fed different rations. One lot was fed in the barn upon a 

 ration similar to Lot 6 in the open shed. 



The following rations were fed : 



Lot i. Shelled corn seven parts, cottonseed meal one part, 

 corn silage. 



Lot 2. Shelled corn two parts, oats one part by weight, clover 

 hay, corn silage. 



Lot 3. Shelled corn and clover hay. 



Lot 4. Shelled corn and alfalfa hay. 



Lot 5. Shelled corn seven parts, cottonseed meal one part, oat 

 straw, corn silage. 



Lot 6. Shelled corn, clover hay, corn silage. 



Lot 7. Shelled corn seven parts, cottonseed meal one part, 

 clover hay, corn silage. 



Lot 8. Shelled corn four parts, cottonseed meal one part, 

 clover hay, corn silage. 



Lot 9. Shelled corn, clover hay, corn silage (fed in barn).
