New York AGRICULTURAL EXPERIMENT STATION. 105 
periods of feeding, when mangels were fed with grain, usually lin- 
seed meal, it was found that mangels were sometimes profitably fed 
even in large proportion. Four lots of pigs fed mangels to the ex- 
tent of from 95 to 98 per ct. of the total food made steady and fair 
rates of gain. With two lots of Duroc pigs the increase in weight 
was at a profitable rate and with two lots of Cheshire pigs the in- 
crease was less and hardly made with profit. In these periods of 
feeding there was little difference on the average whether salt was 
fed or not. In two other periods, with mangels constituting from 95 
to 96 per ct. of the food, there was a profitable rate of growth by 
one lot of each breed, but with salt added to the ration for the 
other lots (% ounce per day per 100 pounds live weight fed), the 
growth was slower and unprofitable. 
Two similar lots, each containing Poland China, Berane Duroc 
and Chester White pigs and some of Cheshire cross, were fed man- 
gels freely with linseed meal and some skim milk, with alternating 
periods when corn meal replaced a larger portion of the mangels. 
It was found that the increase in weight was made at considerably 
less cost for food when mangles constituted about 50 per ct. of the 
total food (about 38 per ct. of the dry matter) than when corn 
meal replaced them in part so that they supplied only from 9 to 13 
per ct. of the total food. 
Increase in weight was considerably faster under the rations 
largely of grain but was secured at a greater cost per pound. The 
mangels being rated at $3 per ton, the linseed meal at $28, and corn 
meal at $24 per ton. 
OAT-AND-PEA AND BARLEY-AND-PEA FORAGE. 
Some limited feeding trials with these fodders, while not con- 
clusive, indicated that only moderate quantities could be profitably 
used without great waste, and that mixed fodders might vary enough 
in character to give quite different results. Mixed fodders, espe- 
cially those including cereals and grasses, are usually in condition 
for feeding pigs for only short periods. 
SALT IN THE PIGS’ RATION.? 
The question of adding salt in small quantity to the ration. for 
pigs that.were not fed skim milk or similar products was considered
