85. Body fat from nutrients.— The following table from Kellner^ 

 summarizes his studies on the amount of fat which may possibly be 

 formed in the body of the growing ox from 100 lbs. of digestible 

 matter of the several nutrients fed in combination with a basal 

 ration already exceeding the maintenance requirements of the ani- 

 mal: 



Energy available 



for fat formation Possible fat 



Therms Lbs. 



Fat 204-259 47.4-59.8 



Protein 102 23.5 



Starch and fiber 107 24.8 



Cane sugar - 81 18.8 



The table shows that if an ox is getting enough food for main- 

 tenance, supplying 100 lbs. of fat in addition may result in the 

 storage of from 47.4 to 59.8 lbs. of body fat. For the other nutri- 

 ents there is a smaller deposit, cane sugar forming only 18.8 lbs.
