feeding stuff inspection. 5 1 



Discussion of the Results of Analyses. 

 With the small appropriation made by this State for the in- 

 spection of concentrated commercial feeding stuffs, it is not prac- 

 ticable to collect samples of the feeding stuffs on sale in Maine 

 as frequently as a thorough inspection demands ; nor is it possi- 

 ble to make as complete analyses of the samples collected as is 

 desirable. The tables show, however, that a large number of 

 samples have been received. The most valuable constituent of a 

 feeding stuff, from the standpoint of the purchaser, is protein. 

 Fortunately this can be determined at less cost than any other 

 ingredient. For these reasons protein has been determined in 

 every sample collected. Fat is fairly uniform in high grade 

 goods of the same class and on this account its determination is 

 of less importance. It was, therefore, for the most part deter- 

 mined in only one sample of each brand. The determination of 

 woody fiber in many kinds of goods is very important and it is 

 to be regretted that the funds available for this work are too 

 small to admit of its estimation in any of the samples. In case 

 of certain possible adulterations the ash should be determined. 

 This has, however, for the same reason, been impracticable. 



cottonseed meal (analyses pagfs 39-44). 



Cottonseed meal is a by-product from the manufacture of cot- 

 tonseed oil. After the cotton has been taken from the seed in 

 the cotton gin, the remaining down or "linters," and the hard 

 black seed coats or hulls are removed by machinery. What re- 

 mains of the seed is cooked, and the oil expressed by high pres- 

 sure. The resulting cottonseed cake is ground into the bright 

 yellow cottonseed meal of commerce. Such a meal carries from 

 40 to 50 per cent protein. 



The shippers of cottonseed meal for the most part guarantee 

 43 per cent protein and 9 per cent fat. According to the classi- 

 fication of the Cotton Seed Crushers Association, "prime" cotton- 

 seed meal from the Gulf States must carry not less than 8 per 

 cent, and that from the South Atlantic States not less than jy 2 

 per cent ammonia. As 8 per cent ammonia is equivalent to only 

 41.19 per cent protein, it is evident that the minimum guarantee 

 is placed higher by the shippers than the Association calls for in 

 prime meal. Hence a meal that carries 41 per cent protein is
