This means that a good growth of wool will be secured 
by any mixture of suitable feeding stuffs from which 1000 
Kilograms of living sheep can daily extract 1.2 Kilograms of 
crude protein, 10.3 Kilograms of carbohydrates and 0.2 
Kilograms of fat and the total bulk of which is approxi¬ 
mately indicated by the amount, of total organic matter 
(20 Kilograms). 
Rations that approximately coincide with the feeding 
standards, can, of course, only be compounded, when it is 
known how much of each digestible nutrient is contained 
in the several feeding stuffs. Hence arose the necessity to 
determine the digestibility of the fodders in those conditions 
of preparation (raw, cooked, steamed, fermented, green, 
dried, etc.) and stages of growth in which they are com¬ 
monly used. Experiments of this kind have likewise 
formed of late years a prominent part of the work of the 
German Experiment Stations. Nearly 3000 different sorts 
of feeding stuffs have already been submitted there to 
trials with animals and their minimum, maximum and 
average contents of digestible nutrients ascertained. The 
results thus obtained were tabulated and are in the hands of 
all educated farmers, who are thus enabled to feed their 
live-stock without running the risk of giving too little or 
too much food. 
The feeding standards are valid at least for all mode¬ 
rate climates, as the changes of heat have, within ordinary 
limits, but little influence on the destruction or deposition 
of nutrients in the animal body ; hence they can be safely 
applied also in this country.—With regard to the feeding
