DISCUSSIONS OF RESULTS. 



In the following tables are given the results of analyses of 1530 feeds, 

 twenty-two of which are not subject to license. Of the 1508 licensed 

 feeds 97 (6.4%) were below guarantee in protein; seventy-two (4.8%) 

 were deficient in crude fat and one hundred twenty-six or 8.4% con- 

 tained an excess of crude fiber. These figures show a very satisfactory 

 reduction in the number of violations of the feeding stutfs law. There 

 has been a steady decrease east year in the number of feeds that have 

 failed to conform to guarantee as is shown by the following table:

In making these computations the following allowances for varia- 

 tions from guarantee were made, protein 1.0 per cent, fat 0.5 per cent 

 and fiber 1.0 per cent. 



All samples of mixed feeds were examined micrctscopically to deter- 

 mine the ingredients and those identified are given in the table of analyses. 

 It is not claimed that every ingredient in each feed was identified as a 

 material could be present in so small a quantity as to make its identifica- 

 tion almost if not quite impossible. 



The term "Oat meal mill by-products" will frequently appear in the 

 list of ingredients. In all cases this refers to oat hulls, oat shorts and oat 

 middlings in the proportion, presumably, in which they occur as by- 

 products in the manufacture of oat meal, which is approximately as fol- 

 lows : oat hulls 90 per cent, oat shorts 8 per cent, oat middlings 2 per 

 cent. This i)roduct is essentially oat hulls and the analysis shows it to 

 possess only a very slightly higher feeding value than the clear hulls. 



Concerning samples No. B 4448 Ryde's Milk Mash and No. B 4853 

 Ryde's Cream Calf Meal, Ryde & Co., in explanation for the- high crude 

 fiber results, state that they received a poor grade of alfalfa meal, some 

 of which was 'used before the poor quality was detected and further 

 tliat in moving the new plant some difficulties were experienced with labor 

 and machinery. 



A discussion of the results for each class of feeding-stuffs follows: 



COTTONSEED MEAL. 



One hundred forty-three samples of cottonseed meal, 37 more than 

 last year, were analyzed. A great majority of these were the "good"' 

 grade, guaranteed to contain 36 per cent protein. This is the lowest 

 grade of meal recognized and is made by adulterating the higher grade
