ing an albuminoid ratio of I : 5-38. The round figures I : 5-4 

 were for a time pretty generally accepted as the standard 

 both in Europe and America. In 1904, Professor F. W. Woll 

 of Wisconsin Experiment Station struck an average of 128 

 rations used in dairies in different parts of the United States, 

 and his results are now accepted as the 1 



American Standard Ration for Dairy Cows of 1000 Ibs 



live-weight.

This distinctly wider nutritive ratio makes it possible to 

 consume a larger proportion of home-grown produce. It is 

 thus more economical during a period of highly priced feeding 

 cakes like that of 1905-7. 



Tuberculosis 2 is a specific disease due to the Bacillus 

 tuberculosis, which produces consumption in human beings. 

 It is well known to attack cattle, horses, pigs, and poultry. 

 Goats and sheep have been generally accredited with 

 immunity, but it is now too prevalent among longwool rams 

 confined under cover and forced for public sales in an 

 unnatural and unwholesome atmosphere. Even the naturally 

 hardy Scotch Blackface Mountain sheep is liable to it, shut up 

 and highly fed in a house at home and covered with tarpaulin 

 in the modern showyard. Wild animals are rarely affected,
