718. Ewe's milk. — In America sheep are not generally used for 

 producing milk for man, but in many districts abroad, especially the 

 mountain regions of Continental Europe, their milk is extensively 

 employed, partly for direct consumption and to a larger extent for 

 the manufacture of cheese. Ewe's milk has a peculiar, somewhat 

 unpleasant odor and taste, and differs from cow's milk mainly in 

 its greater proportion of fat and protein. It is also thicker and 

 sours more slowly. The fat content of ewe's milk is extremely vari- 

 able, ranging from 2 to 12 per cent.^ The butter is pale yellow, 

 less firm than cow's butter, and becomes rancid much quicker. 



The yield of milk by sheep will vary greatly according to breed 

 and feed. Sieglin^ states that the East Friesian milk sheep in Ger- 

 many yield at 2 to 3 years of age from 3 to 4 quarts of milk daily 

 for 2 months after weaning their lambs, and keep up an excellent flow 

 of milk during the autumn months. These sheep are prolific, drop- 

 ping 2, 3, and even 4 lambs, individuals lambing twice a year. Three 

 sheep are estimated to consume as much feed as 1 cow. Ordinary 

 sheep yield from 100 to 150 lbs. of milk per year, while the milk 

 breeds produce from 300 to 1,400 lbs.

 of ewe's milk as determined by Sartori and Fleischmann.* For com-
