JUDGING OATS 



Object. To learn to judge oats on the basis of their value for feed. 



Materials. Threshed samples of oats of different varieties and types. 

 If peck samples cannot be obtained, quart samples may be used. 



Method of Analysis. Mix each sample thoroughly and dip out about 

 a heaping teaspoonful. First, analyze the samples, filling out the report 

 card, then score samples from this data. 



Explanation of Score Card. In this score card oats are judged entirely 

 from the feeder's standpoint. It is not possible to make a score card by 

 which a sample of oats could be judged at the same time from the feeder's 

 and the miller's standpoint, and also judge the grain for seed. Different 

 points would be used in each case and different values given them. 



Uniformity in color and size is of only minor importance to the feeder. 

 Divide the sample according to the color of grain. Let the class having the 

 largest number determine the color. Cut one point for each two per cent 

 of other colors. 



Uniformity in Size. Divide the sample into two parts according to size 

 of grain. Estimate per cent of small grains by count. Cut one point for each 

 four per cent of small grains. 



Weight per bushel is a very important consideration in estimating the 

 value of oats for feeding purposes. A heavy weight indicates that the grain 

 was well matured and filled out. In the same variety a heavy lot usually 

 has a less percentage of hull, and, consequently, a higher feeding value than 

 a light lot. The best oats should weigh 38 pounds per bushel. Cut one point 

 for every pound light down to 32 pounds per bushel, and two points for every 

 pound light below this. 



Soundness and Dirt. Sprouted and decayed grains have little more 

 value than so much trash, and may be regarded as such for judging purposes. 

 Separate all unsound grains and dirt, estimate the per cent by weight, and 

 cut two points for each one per cent. This cut is not limited to ten points 

 but may be indefinite. 



Size of Grain. Size varies greatly with varieties but 100 grains of heavy 

 oats should weigh 3 grams. Cut one point for every two-tenths of a gram less. 



Must and Smut. If must and smut are very apparent the sample should 

 be cut 10 points. 



Percentage of Hull. The percentage varies with varieties, the locality 

 in which the oat is grown and also depends on how perfectly the grain
