The winter cost for 147 days was greater than summer mainte- 

 nance for 216 days, per ewe: in Lot I, 31.4 per cent; Lot II, 44.3 

 per cent; Lot III, 30.3 per cent; and Lot IV, 46.2 per cent. 



Table 4 shows the value of wool and mutton and the profit 

 or loss per ewe at varying percentages of lambs raised. The lower 

 cost of maintenance in the lots fed corn silage as a sole roughage 

 did not offset the losses due to high mortality of lambs and ewes, 

 and was, therefore, the least profitable method of feeding pregnant 

 ewes in winter quarters. Considering the ration fed to Lots I and 

 III as unsatisfactory, note the profits at varying percentages in 

 Lots II and IV. The Shropshires produced a higher percentage 

 of lambs, as shown in Table 1.
