Average Composition of Mangels 



A recent Cornell bulletin (No. 243) quotes the 

 following experiments on the value of mangels for 

 milk: "Rather extensive Danish experiments indi- 

 cate that a pound of dry matter in roots is about 

 equal to one pound of the cereal grains, or to 

 three-fourths of a pound of cotton-seed meal, when 

 fed to milch cows. In these trials no silage was 

 fed, the basal ration in each case consisting of six 

 and one -half pounds of hay and ten pounds of 

 straw per cow. The experiment was so conducted 

 as to eliminate, apparently, the factor of succu- 

 lence, as shown by the following table of average 

 of six experiments including about 150 cows dur- 

 ing several months. Basal ration six and one-half 

 pounds hay, ten pounds straw: .
