The Ohio Expeiimenl Station from the examination of GO varieties 

 of oats, found a range in the jjerceutage of hulls, of 2-1. G to 35.2 per 

 cent., average 30 per cent. 



In the cleaned grain before milling the proportion of kernel is 

 therefore 70 pounds per hundred; but, owing to the breakage of the 

 kernel in milling, the yield of kernel is slightly reduced, being 07 

 pounds per hundred, on the average. 



Under Kichardson's directions, 179 samples of oats and 100 samples 

 of oat hulls were analyzed, with the following percentage results: 



Moisture, 

 Ash, ...

While tlie kernels themselves are richer in protein than those of 

 any other cereal, the adherent hull makes them, as fed, little 

 richer than corn. However, tlie low digestibility of the fiber of the 

 entire oat so reduces the proportion of digestible carbohydrates as 

 to give to this feeding stuff a relatively high nutritive ratio. The 

 hulls, considered alone, while they contain as much nitrogen-free 

 extract as the kernel, really contain it less in the form of sugar and 

 starch than in that of the less valuable pentosans, while the high 

 fiber, low fat and low protein all tend to rank the hull with corn cob 

 and straw in nutritive value. 



The analyses reported by Richardson do not afford a convenient 

 statement of the variations in the composition of American oats. 

 For this, 30 analyses compiled by Jenkins and Winton may be used: 





Moisture 



Ash 



Protein
