THE HOG [NDU8TRY. 
139 
During the two years following the above experiment Sonle and 
Fain ' studied the value of skim milk in a corn-meal ration and in a 
mixed-meal ration. The pigs of the first year were of Chester White 
and Berkshire blood, some being Chester grades and others said to 
be Chester White-Berkshire crosses. They were above the average 
in quality. Those of the second year were Berkshire grades, below 
the average of the preceding year. The pigs were confined in pens 
and fed twice daily. Feeding was carried on through the winter. 
'Hie first winter "was cool and bracing and uniformly dry;" the 
second "was raw and damp, with an excessive rainfall, and this no 
doubt had an influence on the general health of the hogs." 
The lots which were used to compare a straight corn-meal ration 
with a corn-meal and skim-milk ration received, respectively, rations 
of corn meal only and corn meal and milk in the proportion of 1 to 8 by 
weight at the start, the milk being decreased toward the close so that 
the proportion of meal to milk was about 1 to 7. 
Corn meal was charged at 828 per ton during the first year and at 
$19 per ton during the second year. Skim milk was charged at 84 
per ton during both years. 
The following table shows some of the results of this investigation.

The favoraDle results from the feeding of skim milk with corn meal 
are very noticeable in these results. Although the addition of skim 
milk added to the cost of the total feed and the feed per 100 pounds 
gain was accordingly higher, the profit for the pigs on skim milk was 
83.91 more than that of those on corn alone.
