FLUSHING TO INCREASE LAMB YIELDS. O 
In the case of Lots 3 and 4, both of which were in quite low condi- 
tion when breeding commenced, there was an average increased gain 
of 12.38 pounds in weight over the unflushed lot and an increase in 
lambing at the rate of 30 lambs per 100 ewes in the number of lambs 
dropped by the flushed lot. 
In the second instance the unflushed Lot 9 gained an average of 
3.03 pounds per head, while flushed Lot 10, receiving grain, gained 
an average of 12.25 pounds per head and Lot 11 (pasture flushed) 
gained 11.86 pounds per head. The unflushed lot produced lambs 
at the rate of 120 per 100 ewes, while the grain-flushed lot produced 
lambs at the rate of 150 per 100 ewes and the pasture-flushed lot 
produced lambs at the rate of 145.5 per 100 ewes. 
In the third instance Lot 18 gained 1.55 pounds per head and pro- 
duced lambs at the rate of 122.2 per 100 ewes. Lot 19 (grain flushed) 
gained 3.37 pounds and produced lambs at the rate of 147.4 per 100 
ewes, and Lot 20 (pasture flushed) gained 8.15 pounds per head and 
produced lambs at the rate of 169.2 lambs per 100 ewes.

The small number of ewes not getting in lamb in no 
ig flushed. 
From date flushing started to date of conception. 
3 The dates of first service show the effect of flushing upon bringing ewes into heat earlier. 
* The date of conception is considered to be the recorded date of service nearest to 147 days prior to 
lambing.
