Feeding Dairy Cattle 



Whatever the process of manufacture, the resulting meal 

 is graded into three grades. The first grade, choice cotton- 

 seed meal which is defined as follows: "Choice cottonseed 

 meal must be finely ground, not necessarily bolted, perfectly 

 sound and sweet in odor, yellow, free from excess lint and 

 must contain at least 41 per cent, protein." 



The second quality of cottonseed meal contains more 

 hulls than the first and consequently less protein. This 

 second qualit}- is called prime cottonseed meal and is 

 defined as follows: "Prime cottonseed meal must be finely 

 ground, not necessarily bolted, of sweet odor, reasonably 

 bright in color, yellow not brown or reddish, free from 

 excess lint and must contain at least 38.6 per cent protein." 



The third quality of meal is called good cottonseed meal 

 and is defined ofificially as follows: "Good cottonseed meal 

 must be finely ground, not necessarily bolted, of sweet odor, 

 reasonably bright in color and must contain at least 36 per 

 cent, protein." 



Thus it will be seen that no by-product of the cottonseed 

 industry can be called a meal and be sold as such unless it 

 contains 36 per cent, protein. Any by-product of cottonseed 

 sold for feeding purposes must be designated cottonseed feed 

 if there is less than 36 per cent, protein in it. 



In tentative definitions it has been proposed to change 

 the name of the two lower grades of cottonseed meal to 

 medium and lower grade cottonseed meal instead of prime 

 and good cottonseed meal. There is a feeling that cotton- 

 seed meal containing only 36 per cent, protein and thus a 

 large number of hulls should not be called good cottonseed 

 meal. 



To show the amount of hulls which may be incorporated 

 into these three grades of meal the following result of analy- 

 sis is given. A choice cottonseed meal containing at least 

 41 per cent, protein may contain 9.2 per cent, hulls by weight. 

 Prime cottonseed meal running between 38.6 per cent, and 

 41 per cent, protein may contain 13 per cent, hulls. Good 

 or low grade cottonseed meal may contain as high as 27 per 

 cent, hulls and still have 36 per cent, protein in it. There- 

 fore, it will be seen that when a farmer buys good cottonseed 

 meal, so called, he may be buying as high as 27 per cent, 

 hulls, or one-fourth of his meal may be hulls. Cottonseed 

 hulls' are about the poorest material that we can think of for 

 feeding our animals. Since there are so many hulls to be 

 gotten rid of, the amount of cottonseed meal on the market 

 the past year has been almost entirely of the 36 per cent
