a screw press and the oil extracted by pressure. The residue from 

 this process consisting of the hulls, meal and such lint as was not 

 removed constitutes the cold pressed cotton seed cake which is sold 

 as a feeding stuff without further crushing. It is a light, rather 

 fluffy material containing on an average less crude fat and 17.5 per 

 cent less crude protein than cotton seed meal. Cold pressed cotton 

 seed cake is not as valuable for milk and butter production as an 

 equal weight of choice cotton seed meal and hulls mixed in the pro- 

 portion of two parts of meal to one part of hulls. The analysis of 

 cold pressed cake is a reliable indication of its feeding value. Among 

 the principal claims made for this product is that not having been 

 f.'ooked the albuminoids are more digestible than those in cotton 

 seed meal and being more bulky and less concentrated it can be fed 

 in large quantities without danger of the undesirable results pro- 

 duced when excessive amounts of cotton seed meal are used. 



Cotton Seed Feed Meal is a trade name used to designate a mix- 

 ture of cotton seed meal and cotton seed hulls generally in the pro- 

 portion of 50 to 55 per cent hulls. 



Cotton Seed Hulls are the outer portion of the cotton seed. 

 They are high in crude fiber and have little feeding value. Their 

 principal use is as a filler, as a source of roughage and as an adul- 

 terant for cotton seed meal. 



From Barley. Malt Sprouts consist of the dried shoots secured 

 in the germination of barley in the production of malt. They are 

 low in crude fat and rich in crude protein. 



Dried brewers' grains consist of the residue left after mashing 

 the malt, whereby the greater portion of the carbohydrates is re- 

 moved, leaving a residue rich in protein, which, on drying becomes 

 a valuable feeding stuff. 



From Alfalfa. Alfalfa meal consists of ground alfalfa hay. 

 The better grades of alfalfa meal contain a larger proportion of 

 leaves than stems. 



Corn and Oats Feed. Corn and oats feed, usually sold under 

 the name of Corn and Oats Chop, or Chop Feed, are prepared by 

 mixing corn and oats together, generally in the proportion of 56 

 pounds of the former to 32 pounds of the latter, and then grinding. 

 (Ind. B. 141.) 



Animal Meals. These consist of by-products from the packing 

 industry, such as dried blood, meat meal, blood meal, digester tank- 

 age, etc. They are very rich in protein, and have been found to be 

 an excellent concentrate in a ration for swine. They are sold in a 

 dry condition, finely ground. In some cases the bone has been sub- 

 jected to steam under pressure or kettle rendered, in which case the 

 resulting product is lower both in fat and protein. (Dep. Agr. Bu. 

 Chem. B. 108.) 



Dried Blood. This is a product from packing houses, prepared 

 as follows: The blood runs from the cattle when stuck, into a re- 

 ceptacle from which it is promptly pumped into a cooking tank 

 where it is cooked to a point where the water separates from the clots. 

 It is then dropped into large press cloths and put under hydraulic
