F. THK. RESULTS DISCUSSED. 



I. Protein Feeds. 



An attempt is being made to introduce this material 

 Blood Meal, into Massachusetts markets as a food product. It 

 Page 8. is the highest grade concentrate offered, containing 



over 86 per cent protein and only traces of fat. The 

 remainder of the product consists of water and ash. The samples 

 taken, were clean, of good mechanical condition, and almost free 

 from odor. Present sales will probably not warrant any definite 

 retail price, the figures mentioned varying from two and one-half to 

 six dollars a hundred. An experiment recently completed with milch 

 cows, indicates that pound for pound the protein in blood meal is 

 equivalent to that contained in cottonseed meal. 



Cottonseed meal : The quality of the meal found w'as 

 Cottonseed and very satisfactory, and the various lots with a few 

 Linseed Meals, exceptions were tagged in conformity with the statute. 

 Pages 8-10. The color was bright yellow, and the average protein 

 content of the 52 samples collected was 43.79 percent 

 The manufacturers of late years have succeeded in more thoroughly 

 removing the oil, only three samples in the present collection show- 

 over 1 1 per cent of fat. A slight excess of linters(cotton)and hulls were 

 noticeable in some instances. While a few samples were somewhat 

 inferior, there was no indication of intentional adulteration. One to 

 three pounds of cottonseed meal daily forms one of the cheapest 

 sources of protein for dairy animals. 



Linseed meal : Of the ten samples collected, three were new and 

 the remainder old process. They were free from adulteration and 

 as a whole of fair quality. The percentage of fat was slightly higher 

 than a few years ago, especially in the old process meals, and in 

 this latter case, resulted in lowering the percentage of protein. 



Gluten vieal : Chicago gluten is again on the market 



Gluten and Cream gluten meal bears the name of another 



Products. firm and a higher guarantee. The six samples of 



Page II. meal collected were of excellent quality, containing 



on the average 39.77 per cent of protein and 1.43 per 



cent of fat. The fat content has steadily decreased and the 



minimum guarantee should be reduced to about i percent.
