these feeds are composed of nutritions ingredients, and in only a few 

 cases have low-grade materials been introduced into them. 



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

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



COTTON-SEED MEAL FEEDS. 



Cotton-seed meal which does not come up to the standard of 6.18 

 per cent nitrogen may be sold as feed meal and labeled with a feed 

 guarantee in place of a nitrogen guarantee. 



During the past year there has been an increased demand for a 

 low-grade cotton-seed meal or a meal-and-hull mixture for feeding 

 purposes. This has caused to be placed on the market quite a number 

 of brands of meal and hull mixtures sold under the names of '^Cotton- 

 seed Meal Feed," 'Teed Meal," etc. This class of feeds vary very 

 widely in their composition, some guaranteeing as low as ten per 

 cent protein while others guarantee thirty-eight per cent protein. 



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. 



The purchaser should pay especial attention to the price of these 

 mixtures as compared with cotton-seed meal to see that he is not pay- 

 ing a higher price for his protein in this diluted form than he is pay- 

 ing in the more concentrated 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 ex- 

 tracted 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 ex- 

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



N"ew Process Meal — Protein, 32.20 per cent; fat, 3.00 per cent; 

 fiber, 9.50 per cent; nitrogen-free extract, 38.40 per cent; water, 

 10.10 per cent; ash, 5.80 per cent.f 



PEANUT MEAL. 



Peanut meal is the ground cake resulting from the extraction of 

 oil from peanuts. This makes a very rich feed. Frequently con- 

 siderable quantities of peanut hulls are ground with cake. This 

 lowers the value of the meal considerably, as the hulls are practically 

 worthless as a feed. 



Average analysis (3 samples) : Protein, 29.50 per cent; fat, 11.38
