ingredients to one of protein as narrow. ‘Thus rations of 1:6.5, 
1:7, 1:9, and 1:12, that is, from 6.5 to 12 parts of fuel ingredi- 
ents to 1 of protein would be wide, while ratios of 1:5°6, 
1:4.5, or 1:4 would be narrow. 
Most of the grasses, also corn fodders, corn silage, stover, 
oat hay, corn meal, etc., have relatively small quanties of pro- 
tein, and hence have wide nutritive ratios, while the legumes, 
such as the clovers, alfalfa, vetch, peas, immature grasses, as 
rowen, and some milling products, are relatively rich in pro- 
tein, and have narrow nutritive ratios. 
Szze of the Ration.—The total amount of the different nutri- 
ents fed makes up the size of the ration. This should be regu- 
lated by the weight of the animal and the amount of its product. 
In the current feeding standards, the size of the ration is com- 
monly stated as so many pounds of digestible protein, fat, and 
carbohydrates per day per 1000 pounds of live weight. In 
feeding for milk, however, the quantity of that product given 
should regulate quite largely the size of the ration. A cow of 
800 pounds live weight in the ‘‘flush,’’ producing 30 pounds of 
milk per day, will often require a larger ration than a cow 
of rooo pounds live weight, producing but 20 pounds of milk 
per day. The heavier ration may also be more profitable for 
the lighter animal while producing a large amount of muk. 
NITROGENOUS FEEDING STUFFS FOR MANURE. 
The value of nitrogenous feeding stuffs for manure is an 
important factor in their use. ‘This is especially true in the 
older parts of our country where the fertility of soils has been 
reduced by long cropping. Nitrogen is the most expensive 
ingredient in the fertilizers we purchase. It costs three or 
four times as much per pound as potash, and two and one-half 
or three times as much as phosphoric acid. 
The real value that the farmer is able to get out of his fod- 
ders in the form of manure depends upon the composition of 
the fodder, the kind of animal, the use to which the animal 
puts its food, and, most of all, the way in which the manure 
is cared for. ‘The leguminous coarse fodders, such as clover, 
vetch, and peas, have a much higher manurial value than sim- 
ilar fodders of the grasses, corn stover, corn fodder, etc.
