contains. The main reason for its present limited used as a stock 

 feed is, however, that the seed can generally be sold for a good price 

 at the oil mills, or exchanged for cottonseed meal at the rate of 800 

 pounds per ton of seed. Direct experiments with fattening steers 

 and dairy cows at Southern experiment stations have shown that it 

 requires approximately 2 pounds of cotton seed to equal 1 pound of 

 cottonseed meal in feeding value. Boiled or roasted cotton seed 

 has been found to produce larger gains and to be more palatable 

 and less laxative than raw seed, but the gains made are more 

 expensive owing to the cost of preparing the seed. Moldy or heated 

 seed should never be used for feeding farm animals. It is only under 

 exceptional conditions that cotton seed is now fed to farm stock, 

 having been largely replaced by cottonseed meal for this purpose. 13

QUESTIONS 



1. What are the main cereal grains used for feeding farm animals? 



2. Give the classes of animals to which each kind is preferably fed; their 



average chemical composition and relative feeding values.
