MAl^UAL OF CATTLE-PEEDIKG. 435 



These quantities are more tlian supplied by any ordinary 

 ration, and only in ca&e o£ almost exclusive feeding with 

 straw, chaff, and roots is it, perhaps, advisable to add a 

 little lime to the fodder, in the form of lixiviated chalk or 

 fine leached ashes. The latter should be sifted before 

 nsing. Potash is always present in more than sufficient 

 quantity in all vegetable products. 



Common salt constitutes, of course, an exception to the 

 above remarks. The large amount of potash salts in the 

 ordinary fodder of milk cows causes an increased excretion 

 of soda salts from the body (see p. 2-i), and calls for a sup- 

 ply in the food. Salt also increases the palatability of the 

 fodder and stimulates the appetite, a point the importance 

 of which has already been alluded to.
