RATIONS FOR MILCH COWS. 153 



amounts are perhaps excessive. There are many authorities 

 who recommend as an outside limit 4 per cent, of their weight. 



Soured cossettes when given alone as a forage are not desirable, 

 notwithstanding the fact that some experiments which have been 

 made are rather encouraging in their results. Without doubt, 

 from a chemical standpoint, there are certain constituents lack- 

 ing to form a complete forage. They may contain nitrogenous 

 elements in sufficient amounts, but this quantity is not sufficient 

 to do away with other combinations furnishing additional nitro- 

 gen. The proportion between the nitrogenous and non-nitro- 

 genous elements may be put down as 1:8. This, however, 

 depends upon the condition one wishes to find the animals in 

 after their feeding, and also depends upon the work they are 

 called upon to perform. In the latter case it is well that this 

 relation should be 1:5 to 1:6.5. 



In all these considerations it is well not to lose sight of the 

 physiological condition of the animals being fed. It is import- 

 ant to combine with the cossettes a certain amount of fibrous 

 substances demanded by the intestinal canal. As neither the 

 fresh nor the siloed cossettes contain sufficient albumin and fatty 

 substances, these must be added by the use of hay, chopped 

 straw, oil cake, etc. We do not put special stress upon straw 

 or hay, for many residuums that may be obtainable on any 

 farm, such as cereals, vegetables, etc., answer the purpose.
