The Bulletin. 17 



The feeds sold aa "Dairy Feeds" are usually from three to five per 

 cent higher in protein than those sold as "Feeds" and "Horse and Mulo 

 Feeds." They contain some concentrated material such as cotton-seed 

 meal or oil meal which increases the per cent of protein. 



Several brands of these feeds contain a small amount of salt, ranging 

 from one-half to one per cent. This is added to make the feed more 

 appetizing to the animal and is not objectionable when only a small 

 amount is added and the fact plainly stated on the label. 



ALFALFA FEEDS. 



The rapid growth of the industry of grinding alfalfa hay into meal 

 has recently put on the market a larger number of mixed feeds in which 

 alfalfa is. the principal ingredient. Various materials are mixed with 

 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 analysis, these feeds are com- 

 posed of nutritious ingredients, and in only a few cases have low-grade 

 materials been introduced into them. 



Several brands of these feed^ contain a small amount of salt, rang- 

 ing from a trace to a little over one-half of one per cent. 



COTTON-SEED FEEDS. 



A recent ruling of the Board of Agriculture requires that all mix- 

 tures of cotton-seed meal and hulls which do not come up to the stand- 

 ard 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 Avould mislead the 

 purchaser. Such mixtures must be sold under a feed guarantee in place 

 of a nitrogen 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 

 and in the new process a solvent is used. On account of the extraction 

 being more complete when a solvent is used, the old process meal is 

 richer in fat, while the new process meal is slightly higher in protein. 



Old Process Meal — Average analysis (2 samples) : Protein, 33.87 

 per cent; fat 6.08 per cent; fiber 7.29 per cent; nitrogen-free extract 

 37.89 per cent; water 9.60 per cent; ash 5.27 per cent.
