In potatoes and mangolds according to Warrington the phosphoric 

 acid exceeds the lime, though of swedes and turnips the reverse 

 is said. Rations consisting of oil cakes, cereal grains and straw, 

 and roots will thus contain more phosphoric acid than lime, which 

 condition does not favour bone development or nutrition. 



Leguminous fodders contain an overwhelming excess of lime 

 over phosphoric acid and it is probable that for this reason the 

 inclusion of clover hay in feeding rations must have a beneficial 

 effect upon growth and development (i).

The results are not entirely consistent, but the general indi- 

 cations appears that more food per day is consumed when the 

 animals have exercise and abundance of fresh air, they make a 

 greater daily gain in weight, and each pound af increase is obtained 

 with about the same consumption of digestible matter. 



Influence of cooking food. Several trials were intended to de- 

 termine whether cooking the food was advantageous. In some 

 cases it was apparently economical but the general conclusion ar- 

 rived at was that it did not pay.
