centers. The composition of screenings varies greatly, according to the 

 grain from which they are separated. They are composed largely of 

 weed seeds of various kinds and imperfect grains of wheat, barley, oats, 

 etc. Screenings are of value as a feed material and as they are produced 

 in such large quantities their feeding value should be recognized. 



As screecings are composed largely of weed seeds there is danger of 

 spreading weeds on the land when they are used as feed. This danger 

 has been ovei-come by grinding or roasting the screenings before they 

 are used in mixed feeds. Xo feeds should be used which contain screen- 

 ings which have not been so treated. Screenings containing poisonous 

 seeds such as corn cockle, jinison weed, etc., are not allowed to be sold 

 in this State. 



In the past molasses feeds have been subject to more adulteration 

 than any other class of feed. The molasses has been used to cover u]) 

 such materials as rice hulls, corn cobs, saw dust, etc., which are adul- 

 terants and have no value as feed materials. The molasses feeds now 

 found on the markets are as a rule a clean grade of products which hold 

 up to the guarantees which are made for them. In purchasing any feed 

 of tliis class particular attention sliould be paid to the ingredients of 

 which they are composed. 



ALFALFA FEEDS. 



There are quite a number of mixed feeds on the market in which 

 alfalfa meal is the principal ingredient. Various materials are mixed 

 witli the meal to increase the percentage of fat and make them more 

 nearly balanced feeds. The materials which have been found in the 

 brands on the markets are as follows: Cracked corn, oats, oat products, 

 cotton-seed meal, linseed meal, corn meal, dried brewers grains, wheat 

 bran and middlings. As will be seen from the analyses, these feeds are 

 composed of nutritious ingredients, and in only a few cases have low 

 grade materials been introduced into them. 



There are also quite a number of molasses feeds on the market which 

 contain alfalfa meal. These feeds are usually composed of the same 

 ingredients which are used in the other alfalfa feeds with the addition 

 of molasses or syrup. 



COTTON-SEED FEEDS. 



A ruling of the Board of Agriculture requires that all mixtures of 

 cotton-seed meal and hulls which do not come up to the standard for 

 cotton-seed meal, that is, 6.18 per cent nitrogen or 38.62 per cent protein, 

 shall be branded Cotton-seed Feeds or some trade name which does not 

 contain the word "Meal," or any word that would mislead the purchaser. 

 Such mixtures must be sold under a feed guarantee in place of a nitro- 

 gen guarantee. 



Quite a number of cotton-seed feeds are now on the market, varying 

 very widely in the amount of protein which they guarantee. These 

 mixtures appear to be filling a demand for a medium grade concentrate, 

 higher in protein than the average mill product and lower in protein 

 than cotton-seed meal. 



LINSEED MEAL. 



Linseed meal or oil meal is the residue from the extraction of oil from 

 flaxseed. The oil is extracted by two processes, known as the old process 

 and the new process. In the old process the oil is extracted by pressure
