458 MAlSriTAL OF CATTLE-B^EEBITSTG. 



According to these results, a ration containing 0.38 to 

 0.38 lb, of digestible protein, per day and head, and hav- 

 ing a nutritive ratio of about 1 : 5, will produce in about 

 five montlis the same result as the pooier ration used in 

 Woltt'b experiments (p. 435) did in nine. 



To attain such a result, however, care must be exercised 

 in the choice of the feeding-fotuttb, so as to ensure the com- 

 plete consumption of the ration. Moreover, the cost of 

 such feeding is an important consideration, and the farmer 

 will do well to consider whether it would not be cheaper to 

 use the poorer ration, or even to defer the real fattening 

 until later. (See p. 402.) 



It should be added that these feeding standards, like 

 those for maintenance, apply to animals of medium iinc- 

 ness of wool, w^eighiug, when full grown, 90-100 pounds. 

 Fine-w^ooled animals generally require rather more food 

 than coarse- wooled, and heavier animals need more than 

 lighter. 



g 4, Pigs. 



Variations in Fodder.— In regard to the feeding of 

 pigs to be used for breeding, or which are to bo fattened 

 after reaching maturity, no exact experiments have been 



made. 



More commonly, however, pigs receive a full fattening 

 fodder from the time they are weaned, and the experi- 

 ments on the fattening of pigs are quite nmnerous. These 

 experiments have shown that the fodder of the pig may 

 vary more in its composition than that of almost any other 

 domestic animal, resembling in this respect that of car- 

 nivorous animals. It may be made very rich in protein, 

 having a nutritive ratio of 1:2, or it may safely be made 

 pretty rich in digestible carbhydrates. Addhig to this the
