ANIMAL PRODUCTION.

"Any such circumstances, as drought, or poverty of the soil in calcium and 

 ])hosphorus, as tend to diminish the content of the forage in these elements, 

 at the same time limits the growth of the bones and favors the development of 

 diseased conditions in the animals consuming them. 



" No animals which consume fruits, vegetables, milk, or roughage in sufficient 

 proportion to other food are likely to suffer from an excess of mineral acids 

 in the body. Animals fed too little else than meat, eggs, and cereal foods, in- 

 cluding bread, are more likely than others to suffer from an excess of inorganic 

 acids or a deficiency of inorganic liases. 



" Growing animals, when fed for protracted periods on either cereals or meats 

 alone, suffer from malnutrition of the bones, this ailment being caused by the 

 deficiency of these foods in mineral bases. 



" Swine, because of their very rapid growth, have especial need for calcium 

 in the food, as is indicated by the unusual richness of sow's milk in calcium. 

 Corn contains less calcium than other common grain foods and on that account 

 is less i)erfectly adapted to serve as an only food for swine. 



"Clover and alfalfa are especially rich in calcium and hence serve to make 

 good the deficiency of corn in this element."

Composition of Hawaiian foddrrs. 



" The fat content of the cowpea is lower than that of American cowpeas, but 

 the jack bean and pigeon pea contain a good deal of fat (as estimated by ether 

 extraction). The cowpea has a higher fiber content than the average pea 

 grown in America."
