A TALK ABOUT THE INSPECTION. 

 I. Protein Feeds. 



At the present time cottonseed meal is scarce

to its high protein and low carbohydrate con- 

 tent, it is not advisable to have the grain ration consist wholly of 

 cottonseed meal but it forms an excellent mixture with many feeds 

 especially those rich in starch and relatively low in protein. 



Of the 53 samples reported, 17 fell below their guarantee in pro- 

 tein content. Of these, however, only 9 showed a discrepancy of 

 more than i per cent. 



While the chemical composition of the meal obtained from seed 

 grown in 1908 was quite satisfactory, that obtained from this year's 

 crop, judging from the samples already analyzed, promises to be of 

 somewhat inferior quality. This is explained by some on the ground 

 that early in the season many mills sold short and are now endeav- 

 oring to increase their output by the addition of hulls and linters. 



The Inter-State Cottonseed Crushers' Association at its annual 

 meeting held at Memphis, May 19-20-21, 1909, established the fol- 

 lowing rules for grading cottonseed meal : 



Rule 12, Section i. Choice ivftofi seed meal xwwsi be finely ground, 

 perfectly sound and sweet in odor, yellow, free from excess of lint, 

 and by analysis must contain at least 8 per cent of ammonia (41.00 

 per cent protein) or 49 per cent of combined protein and fat.* 



Section 2. Prime cottonseed meal must be finely ground, of sweet 

 odor, reasonably bright in color, yellow, not brown or reddish, free 

 from excess of lint and by analysis must contain at least 7.50 per 

 cent of ammonia (38.50 per cent protein) or 46 per cent of combined 

 protein and fat.* 



* The station endorses the ammonia or nitrogen but not the combined protein and fat 

 guarantee as a basis for settlement. A lot of meal may contain the requisite 49, 46 or 43 

 per cent of combined protein and fat, but through faulty extraction or for some other rea- 

 son, not the necessary nitrogen, ammonia or protein equivalent. Thus, if a 49 per cent 

 combined guarantee should contain 11 per cent of fat, it would contain only 38 per cent of 

 protein instead of the necessary 41 per cent. Inasmuch as cottonseed meal is purchased 

 primarily for its nitrogen or protein, it is believed to be fairer to adhere to the nitrogen or 

 protein content of the meal as a basis of settlement. In Massachusetts it is illegal to 

 present a combined protein and fat guarantee.
