as completely assimilable, and as compensation for the error introduced by this assumption, the woody. 
fibre is regarded as non-assimilable, Non-nitrogenous extractives and woody fibre are spoken of together 
as carbohydrates. Resuming the case of the dandelion, suppose that 70 °/o of the albumin and 50 °/o of 
the fal are assimilated, the actual percentage of assimilated nutriment is

The amount of albumin in fodder, has, till now, been determined simply from the amount of fh, 
nitrogen found by chemical analysis; the amount of nitrogen >< 6.25 = albumin. This assumes 
that all the nitrogen in fodder is present as albumin. If, for example, 2°/o of nitrogen is found, then 
2 >< 6.25 — 12.5°%o is considered as albumin. Analysis has shewn that 6.25 parts of pure albumin |, 
contain 1 parts of nitrogen; hence the use of the multiplier 6.25. Recent researches, however, tend We 
to show that a large percentage of the nitrogen occurs, not in the form of albumin, but as amides, — 
asparagin for example. What value these amides have for feeding purposes has not as yet been 
determined. It would appear as if they could partly replace the albumin, when used along with it. 
In these pages, then, the nitrogen is still regarded as representing albumin. When the nutritive value — 
of the amides has been experimentally determined, it will be necessary to mention them separately in 
data regarding the composition of fodder. Since so little is at present known regarding them, il is — 
useless to take them into account; nevertheless, when known, the amount of amides present in a — 
fodder is stated in the body of the work. 
The ratio of the assimilable nitrogenous to the assimilable non-nitrogenous nutriment (albuminoid , 
ratio) remains to be noticed. In this ratio the value of fat is taken as 2.44 times that of the carbo- 
hydrates. In the case of Perennial Rye-grass hay it is 5.1 : 35.3 + (0.8 < 2.44) = 1: 7.3.

triment daily: —
