EXPERIMENT STATION BULLETINS. 327 



grit represents the value of the 5 pounds of grain in each 100 pounds of 

 feed which has been replaced with grit. Putting a value of 1 cent per 

 pound on grit it is found that the price on a grit free basis of feeds con- 

 taining this material would be |3.91 per cwt. From the past year's fig- 

 ures it would appear that there is practically no difference in the actual 

 purchase prices of grains whether a feed does or does not contain grit. 

 However, purchasers are advised to investigate the price of both classes 

 of feeds before buying as local prices often vary widely from the average. 



CORN AND OAT FEEDS. 



Most of the feeds in this class are composed largely of corn feed meal 

 mixed with oat meal mill by-products with oats sometimes added. The 

 analyses of the 28 samples collected show 2 or 7.1% below guarantee in 

 protein, 9 or 32.1% low in fat, and 12 or 42.9% high in fiber. Here again 

 the variation is largely due to unwise guarantees. 



WHEAT BRAN. 



The action of the Federal Food Administration in putting a low fixed 

 price on wheat mill feeds brought them on the market in unusual 

 quantities. During the i)resent year 122 samples of wheat bran were 

 collected as compared with 49 samples last year. Only 4 samples were 

 below guarantee in protein and all were equal to guarantee for fat. Ten 

 (8.2%) contained fiber in excess of the guarantee. 



Wheat brans containing no ground screenings are not included in this 

 class as the pure product does not require registration and consequently 

 but few of the pure brans analyzed were guaranteed. The same is true of 

 wheat middlings and wheat mixed feed. 



WHEAT MIDDLINGS. 



One hundred fifteen Samples of wheat middlings Avere analyzed during 

 the year. Of this number one sample was low in protein, seven in fat 

 and nine high in fiber. Both standard and flour middlings are included 

 in the list. The average analysis was found to be 16.9% protein, 5.1% fat 

 and 7.5% crude fiber. Prices were found to vary from |34.GG to |60.00 

 per ton. The first was the government price in bulk at the mill and the 

 latter the highest price found after restrictions had been removed. 



WHEAT MIXED FEED. 



Wheat mixed feed or shipstuff is the mixture of wheat bran and mid- 

 dlings at it comes from the mill in the manufacture of flour. Nineteen 

 samples of such feed were drawn and all were found to be equal to guar- 

 antee in every respect. 



WHEAT AND RYE MIXED FEEDS. 



Eight samples were analyzed and all found to conform to guarantee 

 except one which was high in fiber content. These feeds consisted of 

 a mixture of wheat and 'rye middlings with ground screenings.
