182 RESULTS OF EXPERIMENTS IN SWINE FEEDING 
“eondimental stock feeds.” In summing up, Professor Woll 
says, in part: “ The feeding experiments include twenty-three 
different trials, conducted at more than a dozen different ex- 
periment stations, with 992 animals in all; viz., with 78 steers, 
81 dairy cows, 604 sheep, 112 pigs, and 117 hens... . In 
going over the evidence presented, we find that only two out of 
the twenty-three different trials showed the stock feed to 
possess any merit; the conclusions drawn from the results of 
the twenty-one trials is to the effect that nothing was gained 
by including these feeds in the ration fed; in fact, they were 
shown to be a positive detriment in so far that they rendered 
the rations more expensive and increased the cost of the product 
obtained, whether this be gain in live weight, milk, butter 
fat, wool, or eggs.” 
Among the conclusions drawn from investigation work with 
“stock feeds” are the following: 
“They are of no benefit to healthy animals when fed as 
directed, either as to increasing the digestibility of the feed 
eaten or rendering it more effective for the production of 
meat, milk, wool, ete.” 
“They are of no benefit as a cure-all for diseases of the 
various classes of live stock; neither do they possess any 
particular merit in case of specific diseases, or for animals out 
of condition, off feed, ete., since only a small proportion of 
ingredients having medicinal value is found therein, the bulk 
of the fecds consisting of a filler which possesses no medicinal 
properties whatever.” 
“Exorbitant prices are charged for these feeds.” 
“By adopting a liberal system of feeding farm animals 
and furnishing a variety of feeds, good results may be obtained 
without resorting to stock feeds of any kind. If a farmer 
believes it is necessary to feed stock feeds at times, he can
