DESCRIPTION OF THE LAMBS 



The lambs used in the first trial, covering a period from 

 October 21, 1910 to January 19, 1911, were choice Idaho lambs 

 showing evidences of being a cross of Cots wold rams on fine- 

 wooled ewes. These lambs were very rugged and thrifty but were 

 only moderately smooth in conformation. They were purchased on 

 the Chicago market October 10, 1910 for $6.50 per cwt. After 

 being dipped under the supervision of the U. S. Government in- 

 spectors, they arrived in Lafayette October 12, 1910. They were 

 grazed on a field "of aftermath from a mixed clover and timothy 

 meadow until the afternoon of October 19, when they were divided 

 into lots for experiment. During the last few days on pasture they 

 were fed small quantities of oats and hay. 



The lambs used in the second trial of the series extending 

 from September 21 to November TO, 1911, were also bred in Idaho. 

 and were a cross of Shropshire rams on fine-wooled foundation. 

 These lambs were very uniform; in quality and color, all being black- 

 er brown faced. They were of excellent quality and of low blocky 

 conformation. They were purchased on the Chicago market Sep- 

 tember 12, 1911 for $5.25 per cwt. After being dipped under Gov- 

 ernment supervision, they were shipped to Lafayette, arriving Sep- 

 tember 14, 1911. They were pastured on a field of aftermath from 

 a mixed clover and timothy meadow until the afternoon of Septem- 

 ber 18 when they were brought to the experimental pens and divided 

 into lots for feeding. 



The lambs used in the trial extending from December n, 1911 

 to February 19, 1912 were bred in Idaho and were the product of 

 Hampshire rams on fine-wooled ewes. These lambs were very 

 rugged and heavy boned and graded "choice" but not very uniform 

 in size. They were purchased on the Chicago market November 2, 

 ion, for $5.00 per cwt. The U. S. Government had suspended 

 dipping on November 2; hence these lambs were shipped to 

 Lafayette without dipping. On arrival at Lafayette, November 3, 

 the lambs were given all the hay they would <eat and turned on an 

 aftermath from a mixed clover and timothy meadow. After si: 

 days, they began scouring badly. On the night of November n, 

 severe storm found the lambs in a weakened condition and worked 

 serious results. Several lambs died and the others were sick and 

 unthrifty for several weeks. When started on feed December n, 

 1911, the lambs were in very thin flesh. The lambs were very thrifty 

 during the trial but were troubled the last thirty days by ticks.
