FEEDING VALUE OF HAY AND STKAW. 61 



The composition of clover hay here given is of that cut when in 

 blossom. If cut when ripe, this hay has 4 per cent less of flesh- 

 forming material, 9 per cent less of fat, starch, sugar, and gum, or 

 material for f orming fat and sustaining respiration, and over 12 per 

 per cent more of crude fiber or indigestible matter. 



COMPARATIVE NUTRITIVE VALUES OP HAY, STRAW, ETC., 

 IN ONE HUNDRED PARTS. 



Meadow Hay (as the basis) is estimated at 10.0 



Clover Hay 12.5 



Pea Straw 16.5 



Bean Straw 18.6 



Wheat Straw 2.0 



Rye Straw 1.6 



Barley Straw 2.0 



Oat Straw 1.8 



Corn-fodder, (leaves), (estimated) 2.5 



The different quantities of these several fodders which would 

 have to be fed to produce equal nutritive effects, may be tabulated 

 as follows, each quantity given being equivalent to 10 pounds of 

 common meadow hay of mixed grasses of standard quality.

The last two tables must be taken with some qualifications. 

 The values of these different articles of fodder are subject to very 

 great variations, arising out of the conditions of their growth 

 and the time and manner of harvesting, curing and preserving 

 them. With the single exception of corn-fodder, however, the 

 estimates here given will approach v6ry nearly the actual feeding 

 values as found in practice ; the corn-fodder will be found of 

 somewhat higher value than indicated by the above figures, esti- 

 mated from a comparison of its constituents with those of oat
