THE OIL BY-PRODUCTS 213 



after feeding as much as three pounds of cottonseed meal 

 per day to fattening draft horses, concluded that using cotton- 

 seed meal to replace oats resulted in a cheaper ration, 

 a larger gain, more economical gains, and a higher finish. 

 Kennedy, Robbins, and Kildee, at the Iowa Experiment 

 Station,^ after comparing corn and linseed meal with corn 

 and cottonseed meal for work horses, concluded that cotton- 

 seed meal gave somewhat better results than Unseed meal. 

 The use of either resulted in a substantial lowering of the 

 cost of maintaining the horses. 



Cold pressed cottonseed is the product obtained by 

 subjecting the unheated, undecorticated seed {i.e. the un- 

 hulled seed) to enormous pressure to remove the oil. It 

 includes the entire cottonseed, less the lint and oil removed. 

 It may be sold in large thin flakes, or it may be ground 

 to a meal. It has a lower feeding value than cottonseed 

 meal as it contains much more hulls and hnt. It contains 

 about 27 per cent of protein. It may be used in about the 

 same ways as cottonseed meal. It is sometimes sold as 

 *' caddo cake." 



Cottonseed feed is a mixture of cottonseed meal and 

 ground cottonseed hulls, containing less than 36 per cent of 

 protein. Its feeding value depends upon the proportion 

 of cottonseed meal in it as indicated by its per cent of pro- 

 tein. Usually, cottonseed feed contains about 23 per cent 

 of protein. Consequently, the feeder could not afford to 

 pay for it more than one half the value of choice cotton- 

 seed meal. As a matter of fact, it ordinarily sells for only a 

 few dollars per ton less than choice cottonseed meal. In 

 general it will be more economical for the corn-belt farmer
