the amount of hulls, the poorer the grade in protein of the 

 cake. There are three recognized grades on the market, 

 based on the protein content. These grades are as follows: 



(1) Choice cottonseed meal, in perfect condition, sweet in 

 odor, yellow in color rather than reddish or brown, free from 

 excess hnt, and containing at least 4 1 per cent of crude protein. 



(2) Pritne cottonseed meal, which must be sweet of odor, 

 reasonably bright in color, and containing at least 38.6 per 

 cent of crude protein. 



(3) Good cottonseed meal, containing at least 36 per cent 

 of crude protein, otherwise like the prime in character. 



An excellent and justly popular balanced ration consists 

 of a combination of corn silage or stover, with some shelled 

 or ear corn, and cottonseed meal. Cottonseed meal is not 

 a safe feed for pigs or calves, as it has a poisonous effect, 

 which may result in serious sickness and death. Cotton- 

 seed meal is often one of the most economical protein foods 

 that the cattle feeder can buy, considering the character of 

 the nutriment it contains. It is fed to some extent in the 

 South, along with the hulls, which largely consist of woody 

 fiber, and fair gains in steer feeding have come from this com- 

 bination. Milk from cows fed cottonseed meal produces a 

 harder butter than when corn is used. The fat of steers that 

 have been fed cottonseed meal is also harder than that of 

 steers fed corn meal. One can easily see that in warm sec- 

 tions of the country, as a result of the use of this feed, butter 

 will ship better than it might if some other feed were used. 



Cottonseed feed is a mixture of cottonseed meal and hulls, 

 containing less than 36 per cent of crude protein. 



Cold pressed cottonseed cake is made by crushing the 

 seed under great pressure while cold, thus extracting the oil. 

 It contains considerable hulls, and shows about 21 per cent 

 of digestible crude protein. 



Tankage, or meat meal, is a product of the beef-packing 

 house. It is made from inferior pieces of meat and the trim-
