ALFALFA—ITS GROWTH, DIGESTIBILITY, ETC.

Dry matter,. 90.61 
Albuminoids,.16.60 
Fat, .5.35 
Nitrogen free extract,.59.72 
Fiber, . . . 4.10 
Ash, .4.84 
And from the table of digestibility of feeding stuffs, 
we find in wheat bran, that 
78 per cent, of albuminoids, 
69 per cent, of fat, 
33 per cent, of fiber, 
77 per cent, of nitrogen free extract, 
are digestible by oxen. Multiplying the amounts of the 
different constituents by the digestion coefficients, gives the 
actual amounts of digestible matter. 
Digestible fiber,. 4.10x.33= 1.353 lbs. 
Digestible nitrogen free extract, . 59.72x.77 =45.984 lbs. 
Digestible albuminoids, .... 16.60x.78= 12.948 lbs. 
Digestible fat,. 5.35x.69= 3.691 fibs. 
If it is desired to estimate the amount per ton (2,000 
lbs.), we have simply to multiply these numbers by 20. 
To determine the nutritive ratio in any feeding stuff, 
add together the amounts of digestible fiber arid nitrogen 
free extract and the amount of digestible fat multiplied 
by 21, and divide the sum by the amount of digestible al¬ 
buminoids. This can be illustrated by the nutritive value 
of the wheat bran in question : 
Digestible fiber, . 1.35 
Digestible fat (3.69x2J),.9.22 
Digestible nitrogen free extract, . . . 45.98 
56.55 
56.55 divided by 12.94 (digestible albuminoid)=4.37. 
Or, the nutritive value of wheat bran is 1 : 4.37. The 
nutritive ratio of the alfalfa in the feeding experiment is 
1: 4.90.
