NEW FEEDS. 



Tlie demand for wheat iloiir substitutes luis brouj^ht upon tlie market 

 in abundance several feeds which heretofore were found but infrequently 

 and only in small lots. TTntil recently tliese by-product feeds were 

 usually worked up in ready mixed feeds, now, however, they are on sab' 

 as separate and distinct articles of feed. The more important of these 

 are, barley feed, corn feed meal, oat meal mill by-products (oat liulls, 

 oat shorts and oat middlings) and clipped oat by-product. 



Barley feed is the by-product from the ;naiuiCacture of pearl barley 

 and l>arley flour and consists of the coarse hull and fibrous material 

 surrounding the starchy kernel with some adhering fine particles thereof. 

 This feed is light and bulky, having a high fiber content. The average 

 of samples analyzed during the year follows: moisture, 0.0%; protein 

 9.2% ; fat, 2.5%' and crude fiber, 20.2%. On account of the bulkiness 

 and fibrous quality of tliis feed it is not successfully fed alone but it 

 does make a valuable addition to mixtures of heaVy and compact feeds 

 such as corn feed meal, cottonseed meal and other concentrates of similar 

 character. 



The origin and character of the various oat by-products is covered on 

 a previous page under "definitions.'' The variation in feeding value 

 of these products is wide and hence eacli lot should be bought only upon 

 the basis of the guaranteed analysis. The fiber content of the oat 

 products sold separately or mixed is an indication of the quality of any 

 particular lot in question, the fiber content ot tlie middlings being •4.GSI> . 

 while that of the hulls is 29.2% : — in other words, a high percentage of 

 fiber indicates a large proportion of hulls and a corres})ondingly low feed- 

 ing value. These feeds liave a value similar to barley feed as regards 

 making the grain ration more bulky. 



Corn feed meal is a by-product obtained in tlie manufacture of 

 cracked corn, table meal and corn flour. In feeding value, it is nearly 

 if not quite equal to the entire grain and at times can be purchased for 

 less per ton. In mixing rations for cows and horses, corn feed meal can 

 be used in place of the whole corn meal with little depression of the food 

 value. For feeding pigs the meal should be moistened as otherwise it 

 will be rooted out of the troughs and wasted. 



Corn bran is also derived from the manufacture of table meal and 

 cracked' corn and consists of the transparent outer laj-er of the kernel 

 with particles of the starchy j)ortion adhering; frequently light shrunken 

 kernels and other chaffy materials are present. This product contains 

 from 9 to 12% crude protein, to 8% fat and approximately 10% fiber. 

 Henry and Morrison give the total digestible nutrients as 73.1 pounds 

 per 100 pounds of the feed. The light, flaky character of corn bran, gives 

 it especial value for mixing with heavy, compact concentrates. Some 

 manufacturers grind the bran while others ])ut it on the market as it 

 comes from the mill. 



The extensive use of corn oil for cooking purposes has brought corn 

 oil cake meal on the market in appreciable quantities. It is a valuable 

 feed for dairy cows and is also in high favor with many hog growers. 

 This feed is usually prepared for pigs by soaking a few hours and is
