ANALYSES OF FEEDING STUFFS. 



All samples included in the following tables were collected 

 by Mr. A. J. Richardson as agent for the State Board of Agri- 

 culture. A few samples received from farmers are mentioned, 

 but are not tabulated with the official ones. 



The wheat by-product known as "Mixed Feed" was given es- 

 pecial attention this year, since it is the most widely used of 

 any of the concentrated feeds by the farmers of this state. Sev- 

 enteen different brands were sampled, and represented the feed 

 as sold in all sections of the state. Half of the lots bore no guar- 

 antee of protein and fat, but all were above 15 per cent, in pro- 

 tein and -1 per cent, in fat content. From this standpoint they 

 were all standard material and contained no admixture of corn 

 cob, as some goods have shown in past years. 



A microscopical examination of these feeds showed several 

 to contain weed seeds and one sample was found to contain 

 finely cracked corn. Kehlor, Snowflake and Woolcott brands 

 were most noticeable for the weed seeds, which were sufficiently 

 numerous to indicate the use of screenings. It has always l)een 

 the opinion of this department that it is more economical to 

 purchase bran and middlings, than to purchase mixed feed, on 

 account of both cost and quality. 



The mixture of coarse and fine material in one product ren- 

 ders concealment of impurities easy, and there is always a great 

 preponderance of the cheaper by-product in it. 



There were also received from farmers a sample of bran 

 from Laconia and a sample of mixed feed from Alton. Tii the 

 bran was a large proportion of brewers' grains, while the mixed 

 feed contained a quantity of kaffir corn, partially crushed. 

 Neither lot was branded in any way. 



The list of mixed feeds and their composition follow.s:
