PART I 



CORN SILAGE AND CLOVER HAY AS ROUGHAGE FOR 

 FATTENING LAMBS 



Part I of this bulletin is a report and discussion of the trial 

 relating to the comparison of corn silage and clover hay for fat- 

 tening lambs. This comparison has been made in several previous 

 :rials at Purdue University Agricultural Experiment Station. These 

 >revious trials have shown a high comparative efficiency for corn 

 >ilage. The results are shown in Table I. The first feed given the 

 lambs on November 5 consisted in Lot 3 of seven pounds of oats 

 md 25 pounds of hay twice daily. The hay consumption did not 

 increase above this amount. On the second day the quantity of 

 its fed was raised to eight pounds twice daily per lot. On the 

 ifth day two pounds of shelled corn were added to the ration and 

 m the sixth day the corn was increased to three pounds twice daily 

 lot, and the oats decreased to seven pounds twice daily per lot. 

 'he corn gradually replaced the oats until at the end of ten days, 

 to pounds of corn, no oats, and 25 pounds of clover hay were fed 

 twice daily. The quantity of corn was then raised to 12 pounds 

 r ice daily and remained at this amount for thirty days when it was 

 lised to 14 pounds twice daily per lot. On January i the corn 

 raised to 16 pounds twice daily where it remained until the end 

 >f the trial. The hay in Lot 3 remained at 25 pounds twice daily 

 >er lot until the end of twenty-seven days when it dropped to 22 

 mnds twice daily and remained at this figure for twenty-eight 

 lys when it was again reduced and remained at approximately 21 

 Hinds twice daily per lot until the end of the trial. In Lot 6, 

 iven pounds of oats, 10 pounds of silage and 15 pounds of hay 

 fed twice daily beginning with the trial. The oats were grad- 

 lally increased and changed and replaced by corn as noted in Lot 3. 

 "he hay consumed remained at 15 pounds for sixty days when it 

 r as necessary to reduce the quantity fed. With a few changes, 12 

 mnds twice daily per lot was the quantity of hay consumed after 

 ic end of sixty days. On the fifth day the silage was increased 

 to 12 pounds per feed and two days later to 15 pounds per feed. 

 On the thirteenth day, it was increased to 18 pounds twice daily 

 and on the twenty-fifth day to 20 pounds per feed where it remained 

 mtil the sixty-third day when it was again decreased to 15 pounds 

 where it remained until the end of the trial.
