CONDITIONS GOVERNING EXPERIMENT. 



VALUATIONS OF FOODS. 



The food cost for the growth made is of minor significance so far 

 as it relates to these experiments, but is included in the data. The 

 prices of foods taken with the first feeding trials were retained for all, 

 although for some foods they are lower than those now generally 

 quoted. The weight of any chicks that died was accounted loss in 

 weight when estimating the cost of growth. 



The valuations taken were as follows : For wheat bran, corn meal 

 and malt sprouts $17 per ton, for wheat middlings, ground oats and 

 pea meal $18 per ton, for germ gluten meal and low grade flour 

 $22.50 per ton, for Chicago gluten meal $25, cream gluten meal 

 $29, linseed meal %2y, bone ash and animal meal $40, meat meal $35, 

 and for blood meal $50 per ton. Wheat was rated at 78 cents per 

 bushel and corn at 45 cents, green forage at $2 per ton, Florida rock 

 at $10 per ton and oyster shell at 75 cents per hundred pounds. 



RATIONS FOR GROUPS A AND B. 



The rations for lots of chicks I and II consisted of wheat, cracked 

 corn, corn meal, blood meal, green alfalfa and a mixture (i) com- 

 posed of 4 parts of cream gluten meal, 2 parts each of low grade 

 wheat flour and pea meal, and i part each of corn meal, wheat mid- 

 dlings and blood meal. To the ration for lot I were added 2 ounces 

 of finely ground Florida rock phosphate and i ounce of fine white 

 glass sand to every 24 ounces of the dry food, and fed mixed with 

 the ground grain. To the ration for lot II the same amount of sand 

 was added, except that during the first two weeks twice as much sand 

 was used as for lot I. 



The ration for lots III and IV consisted of the same foods used for 

 lots I and II, in slightly different proportion. Lot III was fed ground 

 Florida rock in the same amount given to lot I and lot IV was fed 

 ground oyster shell equal to one-fourth the weight of the rock fed to 

 lot III.
