Barley. 
Tn grain, barley may have its equivalent represented by 5J ; 
barley meal, by 5. 
In accordance, then, with the results of the foregoing chemical 
analysis and with the facts collected from the feeding of herbivorous 
animals, we may, as the equivalent of the forage supplied for 
cavalry horses, set down the following : — 
( Straw .... 33^ 
I Oats 6 
Hay ... 10, substituted by B ran 7 
I Barley .... 5J 
v Barley meal . . 5 
Determining the commutation of forage by this scale of equi- 
valents : — 
1st. For every 100 of hay should be allowed 335 of straw. 
2dly 100 of oats 89 of barley. 
3dly 100 83 of barley meal. 
4thly 100 117 of bran. 
In fixing the substitute for 100 of hay at 200 of straw, 
the relative prices — hay being double that of straw — appear to 
have been had regard to rather than the nutritive qualities. 
Estimating articles of forage by their price in conjunction with 
their nutritive properties, we find the dearest provender to be 
straw. Regard to these considerations might make it advisable to 
commute a part of the corn for hay ; or two parts of the straw for 
one of hay, providing the litter would admit of such abstraction. 
Tn conclusion, it is our opinion, 
1. That the substitution of corn for hay, within the limits fixed 
by the Committee, must prove advantageous to the nutritiveness 
of the horse’s ration. 
2. And that if we could, without damage to the litter, commute 
two kilogrammes of straw for one of hay, the ration also would be 
sensibly increased in value. 
3. The equivalents of the present Report are those to be pre- 
ferred for the purposes of commutation. 
4. That it would be desirable to introduce into the army the
