day. The grain ration reached 80 pounds for the lot when on full feed, 

 or 13^ pounds per head per day. On January 27th, the pea-and-oat 

 hay gave out and mixed hay was fed instead. Lot A was reduced a 

 little in grain from January 15th to 27th, as were all the lots, because, in 

 the opinion of the feeder, they were being increased a little too fast. The 

 lot was in normal condition at all times and did not seem to be " ofif 

 feed " at any time. One lamb died in Pen 2, Lot /\, on January 27th, 

 but not from " apoplexy." The cause will be discussed at a later point, 

 as will be the gains made by this lot. 



Lot B. — This lot was fed the same amount of grain as Lot A. They 

 were fed no silage, being given more hay in place of the silage. The 

 plan of the ration for this lot is given in Table 2. The lambs were 

 started on 108 pounds of hay, clover hay and pea-and-oat hay, increased 

 gradually to 126 pounds of hay by February 15th, then decreased some- 

 what, reaching 96 pounds per day for the lot of 58 lambs during the last 

 month of the experiment. Lot B seemed to be in good health at all 

 times. No lambs were lost from any of the pens in this lot. 



Lot C. — Lot C was fed a narrow grain ration according to the basic 

 ration given for this lot in Table 3. They were fed no silage. The lot 

 contained 86 lambs. The lambs W'ere started on 141 pounds of hay, or 

 a little over lYi pounds per head per day, and 45 pounds of grain, or 

 about y2 pound of grain per head per day. On February 15th the hay 

 reached approximately 2 pounds per head per day, the lot of 86 lambs 

 being given 174 pounds per day. The hay was reduced until in the last 

 month the amount fed to the 86 lambs per day was 126 pounds, or i^ 

 pounds per head. The grain fed the last days of the feeding period 

 reached 120 pounds, or approximately i^ pounds per day for each 

 lamb. 



No lambs were lost from this lot until after the experiment was con- 

 sidered closed on April 3d. However, on April 9th one of the lambs 

 was lost from Pen 9. The autopsy showed that this lamb died from 

 inflammation of the small intestine and not from " apoplexy." Other- 

 wise the health of the lot was very good and steady gains were made. 



Lot D. — Lot D received a narrow ration with silage as planned in the 

 basic ration for this lot given in Table 4. There were 87 lambs in the 

 lot. They received throughout the experiment 60 pounds of silage per 

 day. The amount of grain fed Lot D was the same as that fed Lot C, 

 being 45 pounds at the beginning and gradually increased to 120 pounds 

 during the last 2 days of the period for the 87 lambs. This lot was fed 

 114 pounds of hay at the beginning, or iV^ pounds per head per day. 

 On February 15th, the total amount fed to the lot reached 151 pounds. 

 During the last month the average amount per day was 113 pounds for 

 the lot, or nearly i^ pounds per head.
