With some reduction of nutrients—The average of 28 records 
which cover periods when there was a reduction of nutrients 
with the same increase of protein as above is shown in C of 
Table XXXI. There occurred a diminution in milk yield at 
about half the normal rate. The gain in live weight was much 
slower after the change than before. 
AN INCREASE IN THE AMOUNT OF PROTEIN ABOVE 2.5 LBS. 
Only 18 records cover periods when this change in the ration 
occurred. With half of them there was an increase of total 
nutrients and with half a reduction. There was a more than 
usually rapid falling off in milk for both groups. On the aver- 
age there was a slight increase in amount of nutrients. The 
average shrinkage in milk was twice as much as it would 
normally be. The gain in live weight was much slower after 
the change of ration. Little change in the cost of production 
occurred.
