THE VALUE OF BUTTERMILK, ETC., IN PIG FEEDING. 67 



Lot III. — The same grain mixture as Lots I and II, with sufficient lactic acid 

 to make the solution test .8 per cent of that ingredient. 



The experiment began September 22 and ended December 1, proceeding without 

 any disturbance.s. The weighing, housing and general care of the pigs were the 

 same as in the preceding experiments. For the first two weeks of the experiment, 

 after the change was made from the corn meal and skim milk to the experimental 

 diet, none of the pigs made much gro\\i:.h; but as soon as thej^ adapted themselves 

 to the new diet a reasonable growth was noted from week to week. 



Dry Matter in Food Consumed and Growth Produced (Pounds). 



1 Pigs 3 and 4 received a total of 604 quarts each of water containing .4 per cent lactic acid, 2.1 pounds per 

 quart. 



2 Pigs 5 and 6 received a total of 616 quarts each of water containing .8 per cent lactic acid, 2.1 pounds per 

 quart. 



From the general appearance of the pigs, and from the above data, one is justified 

 in concluding, in case of both trials, that the lactic acid was without any pro- 

 nounced effect in promoting growth. It is possible that lactic acid may have 

 some therapeutic effect in case of animals undergoing digestive disturbances, but 

 under normal conditions its use is not advised.
