MAINTENANCE OF BREEDING EWES OF MUTTON AND WOOL SHEEP 15 



26 ewes being on the experiment in 1914, and 32 in 1915, a fact 

 showing that 32 ewes approaches a more economical unit than 26 

 ewes. Ewes of all lots made marked increases in weight during 

 the pasturing season. 



Table 7. Annual Cost of Maintaining Breeding Ewes 

 December 5, 1913-May 9, 1916 



1. Shropshires valued at $10 per ewe; Delaine-Merinos at $8 per ewe; at 6 per cent interest. 



2. Shropshires estimated serviceable 4 seasons^ and Delaine-Merinos 5 seasons. Market value of 



Shropshire ewes 160 pounds @ $6 per cwt., and Delaine-Merinos 110 pounds at $5 per cwt. 

 8. Based on results of two ewes dying during the 2% years of the investigation. 



In both the lots fed alfalfa hay as a sole roughage the cost of 

 maintenance was 15.6 per cent greater than in the lots fed corn 

 silage and alfalfa hay. A comparison of the Shropshire ewes in 

 Lots I and II fed the same as the Delaine-Merinos in Lots III and 

 IV, respectively, showed 7.8 per cent greater cost of maintenance 

 for the Shropshire ewes.
