FEEDING OF ANIMALS.

SECTION VI.— THE FEEDING OF ANIMALS FOR THE 

 PRODUCTION OF MEAT, MILK, AND MANURE, 

 AND FOR THE EXERCISE OF FORCE. 



Introduction and History. 



It was shown in the last Section (V.), on the Eotation of 

 Crops, that any explanation of the benefits of rotation is 

 quite inadequate which does not take into account the results 

 of the feeding of the animals on the farm. Thus, in the 

 discussion of the amounts of the produce of the various crops 

 grown in alternation with one another, and of the amounts 

 of the various constituents of the individual crops, or of 

 their separate parts, it was pointed out that only certain 

 portions of them were at once available as saleable products ; 

 a large proportion remaining for use on the farm in some way, 

 and only eventually yielding a profitable return. 



The extent to which the retention on the farm of the 

 constituents accumulated in the crops may take place, may 

 usefully be illustrated by reference to a particular example, 

 which will convey a clearer conception of the importance 

 of the subject than any mere general statement can do. 

 Accordingly, in Table 66 is given an approximate estimate of 

 the proportion of certain selected constituents of the crops 

 grown in the typical four-course rotation of Swedish turnips, 

 barley, leguminous crop, and wheat, which would be at once 

 sold off the farm, and of the amounts retained upon it ; 

 supposing that only the grain of the cereals is sold, and that 

 the root -crop, the leguminous crop, and the straw of the 

 cereals, are retained for further use. The estimates are
