other Scandinavian countries, especially by the cow-testing as- 

 sociations, for measuring the relative production economy of cows. 

 This system is extensively used with cows, occasionally with pigs, 

 and rarely with other animals. It has great merit, especially in 

 cooperative efforts to improve dairy cattle and their feeding — 

 lines in which the Scandinavian farmers are leaders. 



147. The feed unit. — The feed unit of the Danish associations 

 is 1 lb. of standard grain feed, such as corn and barley, or their 

 equivalents in feeding value. In Sweden it is one kilo (2.2 lbs.) 

 of mixed concentrates or their equivalent. All feeding stuffs are 

 reduced to this standard in calculating the feed consumption of the 

 animal. The Danish valuation table is as follows :

It is shown in the table that 1 lb. of Indian corn, wheat, bar- 

 ley, palmnut meal, or the dry matter of roots is taken as the unit 

 standard. On this basis 0.8 lb. of cotton-seed meal or 1,1 lbs, of
