1). RESUME OF EXPERIMENTS WITH STOCK AND 

 POULTRY FOODS. 



A number of experiment stations have carried on experiments 

 with these foods and the results are briefly cited below. 



Plumb' fed American stock food to swine as an ingredient of the 

 daily ration without securing any increase in live weight. The cost 

 of producing a pound of live weight with the condimental food was 

 3.0 cents, and without 2.6 cents. Another experiment was con- 

 ducted with Rusk's and Standard stock foods, with quite similar 

 results. 



The Kansas station" tried both the Acme and Globe stock foods. 

 The Acme produced slightly more milk than the ration not contain- 

 ing it, but at an increased cost of 2.3 cents a pound of butter fat. 

 The ration containing the Globe food produced slightly less milk 

 than the same ration without it ; the butter fat produced with the 

 condimental ration cost 11.7 cents, and without, 11 cents. The sta- 

 tion remarked that such materials, were " worthless for dairy cows 

 accustomed to a good balanced ration.'" 



At the Iowa station"* four lots of six pigs each were fed a basal 

 ration of corn meal to which different kinds of tankage, beef meal 

 and Standard stock food were added. The lots receiving the corn 

 and tankage or beef meal, yielded from seven to thirty-five per cent 

 greater profit than did the corn meal ration, and the lot receiving 

 ■ corn and Standard stock food yielded 10 per cent greater profit than 

 did the corn when fed alone. The increase in growth was probably 

 due to the extra protein and ash contained in the tankage and stock 

 food. 



In another experiment at the same station with steers^ Iowa 

 stock food when fed in conjunction with corn and wheat straw, 

 returned $1.40 less net profit than did a ration of corn and straw; 

 Standard stock food $8.92 less and International stock food $8.16 

 less. The addition of Standard and International stock foods to the 

 corn rations reduced the value of the corn 21 and 24 cents a bushel 

 below that received when corn was fed alone. 



Snyder^ at the Minnesota station concluded that steers digested 

 alfalfa hay fed with corn more thoroughly without the addition of a 

 condimental food than when one was added.
