The Shropshire ewes of Lot I yeaned a higher proportion of lambs, 

 but lost a greater number than the Delaine-Merino ewes of Lot 

 III. The Shropshire ewes required more care at lambing than the 

 Delaine-Merino ewes. 



Lot II, Shropshires, and Lot IV, Delaine-Merinos, were fed 

 corn silage and alfalfa hay as roughage. The greater amount of 

 bedding used by the Delaine-Merino ewes was due to the same 

 apportionment to a smaller number of ewes 11 . 



The proportion of lambs raised by the Delaine-Merino ewes 

 that produced lambs in Lot IV was greater than for the Shrop- 

 shires that yeaned in Lot II. Shropshire ewes in Lot II cost 5 

 per cent more for winter maintenance than the Delaine-Merino ewes 

 of Lot IV.

The cost of summer maintenance was calculated on same basis 

 as that shown in Table 2. The greater cost of 1914 was due to 



Grazing on Hilly Pasture
