Particular attention is called to the low gains of the Razorbacks, 
the Large amount of feed thej^ required for 100 pounds gain, and the 
large amount of internal fat. 
In the Wisconsin a experiment to compare pease and middlings with 
coin meal the Berkshires made an average gain in one hundred and 
twenty-six days of 169 pounds — an average of 1.34 pounds daily for 
each pig. The Poland Chinas gained 153 pounds each — an average 
of 1.21 pounds each daily. The Yorkshires, leaving out of considera- 
tion a pig that fed poorly, made an average gain in one hundred and 
twenty-six days of 137 pounds — an average daily gain each of 1.08 
pounds. The authors of the Wisconsin report state that this should 
not be regarded as a breed test. 
These experiments, taken in connection with the evidence of inves- 
tigators over the entire country, undoubtedly show that representative 
pigs of the different breeds do not differ materially either in the rate of 
gain or the economy with which the gains are made. Any marked dif- 
ferences in the breeds will be manifested in the suitability of the fat- 
tened animals for market and the quality of the carcass on the block. 
A very notable feature is the showing of the bacon breeds when 
compared with the lard breeds. The fact that a pig is a Yorkshire 
or a Tamworth can not be taken as prima facie evidence that it will 
make slow and expensive gains. 
Value of different crosses. — At the Minnesota Station, Shaw 6 fed 
four lots of pigs to determine the relative value of Yorkshire pigs of 
first and second crosses. The pigs of the first cross were by a pure- 
bred Large Improved Yorkshire boar out of a high-grade Berkshire 
sow. Those of the second were sired by the same Yorkshire boar, 
out of a sow whose dam was the grade Berkshire that was the dam of 
the first litter and whose sire was a purebred Yorkshire. The four 
lots were therefore as nearly identical in breeding as possible without 
extreme inbreeding. 
Lots I and III were first-cross pigs and Lots II and IV second cross. 
Lots I and II received a corn-and-oats diet and Lots III and IV a
