THE RATIONS FED. 



Lot III was fed what may be called a carbonaceous ration. The 

 lambs were given all the timothy hay and whole corn they would 

 readily eat, and in addition about a half pound of roots each per 

 day. Turnips were fed as long as the supply lasted ; after that 

 mangels were used. 



Lot IV was fed a nitrogenous ration, although it was not so ex- 

 cessively rich in nitrogen as that used by some experimenters in 

 trials of this kind. The grain ration was made up of two parts 

 wheat bran and one part cotton seed meal. A pound per day per 

 lamb of this mixture was fed at first ; afterward it was somewhat 

 increased or diminished, as the needs of the case required, the ob- 

 ject being to feed about all that would be readily eaten. This lot 

 received clover hay instead of timothy, and roots, as lot III. 



Lot V was fed an intermediate ration. The grain part was com- 

 posed of three parts corn and one part each of wheat bran and cot- 

 ton seed meal. It was eaten in about the same quantity as lot IV. 

 Timothy hay was used for this lot, and roots were fed as in each 

 of the others. 



Lot VI was fed the same as lot V, except that they received no 

 roots at all. In the table below is given the amount of the vari- 

 ous fodders consumed by each lot, together with the amount of the 

 various digestible nutrients that each contained, and the cost at 

 the following prices: Com, $20 per ton; timothy ha}^ $10 per 

 ton; mangels, 5 cents per bush.; turnips, 5 cents per bush. ; wheat 

 bran, $18 per ton ; cotton seed meal, $22.50 per ton ; and clover 

 hay, $7 per ton.
