III. Rations for Growing Animals 



In view of the growth requirements of the young organism, the feed 

 for growing animals should be rich in albumen and mineral matter. The 

 growth of young animals is not absolutely inhibited even when the food 

 supply does not exceed the wastes of the body. Under these circum- 

 stances growth takes place at the expense of the body organs. Under 

 such conditions life can not, of course, be indefinitely prolonged. 



Provided with an abundance of production feed, a suckling calf may 

 make daily gains of 4 pounds or more, per 1,000 pounds live weight, 

 while the mature ox can hardly make gains to exceed 0.6 to 0.8 pounds 

 per 1,000 pounds live weight, per day. Such rapid development of young 

 animals is possible only in connection with an ample supply of easily 

 digestible nutriment of high availability, assisted by the inherent power 

 of the young to assimilate and convert albumens and minerals into body 

 tissue (Fig. 85). 



The power to convert digested nutrients into tissue is gradually re-
