Lot III showed no loss in weight. The others showed a very 
heavy loss in weight especially in view of the fact that they had 
several days in which to make up the shrink before weighing time came. 
The lambs in these two lots made a loss of 924 pounds when they should 
have made 'a gain of about 720 pounds thus losing 1644 pounds of 
gain on 180 lambs, or a trifle over 9 pounds per head. Some of this 
shrink undoubtedly was made up later as the bi-weekly gains for Lots 
I and II are larger during the succeeding weeks than the gains for Lot 
III, in spite of the fact that at the end of the experiment Lot III had 
the greatest average gain per head. 
Cut Hay vs. Whole Hay. 
The entrance of the dogs of course invalidated the results of the 
ration experiments, but at least one interesting point can be gained, 
so the final result for these three lots are given here.

You will note in the table given above that Lot II made practical¬ 
ly the same average gain per head that Lot III made, in spite of the 
fact that the dogs caused a loss in weight for Lot II and did not cause 
a loss in Lot III. 113 pounds more hay were required to produce 
each 100 pounds of gain in Lot II, the whole hay lot, but this is offset 
by the extra cost of the cut hay for Lot III at $1 per ton additional, 
making the cost of 100 pounds gain in live weight stand at $5.70 for 
the whole hay lot and $5.83 for the cut hay lot. 
Figuring hay at $7 per ton, instead of $5, brings the whole hav 
and cut hay lots together at $6.60 and $6.61. And it should be noted 
that the higher the price of hay, the greater the benefit secured from 
cutting the hay. It costs no more to cut a high priced ton of hay 
than a low priced ton, but the saving is correspondingly greater.
