106 TWENTY-FIFTH ANNIVERSARY REPORT. 
in a number of experiments. It was generally added in quantities 
varying from about 4g ounce to % ounce per day for every 100 
pounds live weight fed. The general results from eighteen differ- 
ent periods of feeding with several lots of pigs were: 
With rations of ordinary grain the addition of salt was an ad- 
vantage, but it was not always when some waste cereal products 
were fed. 
When fresh forage, such as clover, sorghum, comfrey, silage and 
mixed fodders constituted the larger part of the ration much better 
results almost always accompanied the use of salt. When grain 
was fed more freely with the coarse fodders considerably better 
results on the average were obtained when salt was fed, but some- 
times there was little difference. 
When mangels were fed in large quantity the addition of salt to 
the ration was a marked disadvantage in all but one period, which 
latter did not give results strongly opposed. It was thought that this 
result was due to the fact that, as mangels contained naturally a 
much larger proportion of salt that most foods, any added made an 
injurious excess. 
WET AND DRY GRAIN FOOD FOR PIGS.1 
To get some data on the recurring question as to the relative 
efficiency of wet and dry grain food two feeding experiments were 
made, one during summer and one during winter. Four lots of 
pigs were used, seven and eight in each lot and of five breeds. Only 
water and several ground grain foods were fed. 
In one ration the grain was fed dry and in the other after stand- 
ing twenty-four hours mixed with water. On the average for 
several months during the first experiment the same growth was 
made and on practically the same amount of food, and there was 
little difference for the several periods of the experiment. 
During the second experiment there was on the average, and dur- 
ing both periods, slightly greater increase in weight and at slightly 
lower expenditure of food under the wet grain ration. Results on 
the whole did not show much difference in favor of the wet food. 
It had been assumed from observation in other feeding that when 
grain was fed dry it was more evenly distributed among the indi- 
vidual animals in the pen, and the fluctuations in rate of growth 
during these feeding trials were in accord with this assumption. In
