in their effect, particularly the old process meal that contains 

 quite a high percentage of oil. This is a safer feed than cot- 

 tonseed meal but the protein costs more. These meals are bet- 

 ter to use with dry, coarse fodders on account of their laxative 

 properties. 



Distillers' grains come next in order of richness in protein, 

 carrying about 31 per cent, and they also carry about 11 per 

 cent oil. It is a bulky feed and is very desirable to feed with a 

 heavy material like corn meal. 



Gluten feed is a by-product which is produced in the manu- 

 facture of corn starch. It is quite bulky and for that reason is 

 a good grain to feed alone. The protein is guaranteed 2^ per 

 cent but usually runs higher. As a source of protein alone 

 these feeds are more expensive than those going before, but 

 they contain more carbohydrates. 



Under class 2 we have the wheat offals, including wheat bran, 

 mixed feed, and middlings. These materials carry from 14 

 to 18 per cent protein, but contain large amounts of carbohy- 

 drates and are rich in ash materials which makes them valuable 

 for growing animals. As a source of protein, however, now 

 they are expensive at present prices on account of their low 

 digestibility. Their bulkiness makes them desirable to feed 

 with heavy grains. Some of the mixed feeds are adulterated 

 with corn cobs and sold under special names. These adulter- 

 ated mixed feeds are reduced in value about one-fourth and 

 sell at nearly the same price as the straight goods. The corn 

 cobs with which they are adulterated have practically no feeding 

 value. Under the inspection laws they are obliged to mark 

 them as carrying corn cobs. 



Under Class 3 would come the oat feeds, hominy feed and 

 corn meal. The oat feeds are a cheap class of feeds and at the 

 present time we are finding very few of them in the State. No 

 one can afford to buy them as they are largely made up of oat 

 hulls that have no more feeding value than oat straw. Under 

 this class corn meal is the most concentrated and valuable feed, 

 but, as you know, carries so little protein that it can only be 

 fed profitably with other material rich in this ingredient. 



We have on the market some other feeds which I have not 

 mentioned under the classes given. Among them are the
