FLUSHING TO INCREASE LAMB YIELDS. 
13 
the twin lambs consisted of If pounds of a mixture consisting of 
cracked corn 80 parts, oats 60 parts, bran 35 parts, in connection 
with 2 pounds of timothy hay and 2 pounds of turnips. On April 6 
the singles weighed 107 pounds and the twins 110. That their extra 
gain was not fat is shown by the fact that after running on pasture 
with no feed until August 10, the twins were 3.1 pounds heavier per 
head than the singles. A comparison of the gains made by singles, 
twins raised as twins, and twins raised as singles, is shown in Table 7. 
The fact that lambs born as twins but receiving all of one ewe's 
milk often equal and sometimes outweigh single lambs makes the 
matter appear to be one of nourishment. The slight lack of growth 
and development of twin-ewe lambs below that of singles at market 
age is not serious in comparison with the advantage of larger numbers.

SUMMARY. 
The practice of extra feeding at breeding time to increase the 
number of twins produced by ewes is called " flushing." 
The percentage of lambs produced by a flock depends upon the 
number of dry ewes and the proportion of ewes producing twins and 
triplets.
