Quantity and Composition of Ewes' Milk 



23 



of milk were secured lo days after the birth of the lamb. This duration 

 of time was allowed to elapse in order to allow the milk of the ewe to 

 become normal. Analyses of ewes' milk, made by Weiske and Ken- 

 nepohP at different periods, varying from i}4 hours to several days 

 after the birth of the lamb, show that 10 days is ample time for the 

 milk flow to assume its normal composition. 



The results of the table indicate, as would naturally be assumed, 

 that there is a decrease in the milk flow of the ewes in the 50-day period. 

 In only one instance was this not true; that was in the case of Cotswold 

 ewe, No. 753, which maintained not only a constant milk flow throughout 

 the experiment, but actually showed a slight increase at the end of the 

 50-day period.
