 Clipped Oat By-Product is similar in composition to oat feed, and is included in 

 the group with oat feed for the same reasons. 



Grain Screenings. This is an indefinite term. Screenings may or may not have 

 considerable food value, depending upon source and proportion of grain, weed seed 

 and other material present. 



Cocoa Shell Meal is of rather low digestibility and has proved very unpalatable 

 when attempts have been made to feed it without mixing with more palatable products. 



Stock Feeds. 



Of the 83 samples of stock feeds collected, 24 showed an excess of fiber, three were 

 deficient in protein, and two in fat. Oat feed is a prominent ingredient of stock feeds. 

 This material contains from 25 to 30 per cent of fiber and usually sells for about one- 

 third of the price of the other ingredients used. An attempt to use a maximum of 

 oat feed often results in inaccuracy of guarantee. 



Poultry Feeds. 



Of all the poultry feeds collected, consisting of alfalfa meal, chick grains, poultry 

 mashes, and the animal products, numbering 320 samples, only 24 showed discrepan- 

 cies in guarantee. None of these was serious except in the case of Randall's Poultry 

 Mash, which showed an average excess of about 6 per cent in fiber for the two samples 

 collected. One sample of Dow's 55% Beef Scraps showed a deficiency of 8 per cent 

 in protein. Two samples of Dow's Scraps were found to contain about 15 per cent of 

 added sand or silica. 



While there are no experimental data at hand to show the effect of quality of meat 

 scraps upon poultry, it is believed that the meat scrap and meat and bone scrap free 

 from taint and odor are to be preferred rather than material that more nearly re- 

 sembles fertilizer tankage. There is a wide difference in meat scraps in this respect. 



Microscopic Examination of Feeding Stuffs. 



The Massachusetts Feeding Stuffs Law requires that a true statement of the in- 

 gredients used in making prepared feeds be a part of the attached guarantee. _ During 

 the year 563 samples of such feeding stuffs have been examined under the microscope 

 in order to determine the accuracy of such statements. With few exceptions goods 

 were as represented, and the variations from guarantee noted were of minor impor- 

 tance and without serious effect upon the feeding stuff in which the variation occurred. 



Samples of Stevens "44" Sweetened Dairy Ration, Auburn Dairy Feed, Conestoga 

 18 Dairy Feed and Protena Dairy Feed were found in which, while the statement of 

 guarantee was correct, the grinding of the screenings contained was apparently so 

 inefficient as to leave many unground weed seeds. 



The following feeds were found which did not conform to guarantee.
