MINERAL CONSTITUENTS OF HAWAIIAN FEEDING STUFFS. « 



In addition to the ordinary nutrients, animals require a certain 

 amount of inorganic material, particularly lime and phosphoric acid. 

 The requirements of a milch cow are stated to be approximately 0.09 

 pound phosphoric acid and 0.13 pound lime in addition to 0.24 pound 

 potash per day. 5 It is usually taken for granted that these amounts 

 will be supplied by an} T ordinary mixed ration and that animals will 

 thus obtain all the ash constituents necessary. 



Hals c estimates that a milch cow producing 11 quarts of milk per 

 day will require at least 0.15 pound lime and 0.1 pound phosphoric 

 acid, and states that as a general rule concentrated feeds are low in 

 lime and high in phosphoric acid, while the opposite holds true with 

 coarse fodders. 



((For discussion of lime as an essential constituent of feeding stuffs, see Hawaii 

 Sta. Press Bui. 15.
