Suggestions for Pig-Feeders. 



831 



It will be useful to compile a final table showing the 

 approximate estimated (theoretical) value for pig-feeding of 

 the various average crops produced on one acre in Great 

 Britain. For the sake of comparison the quantities of skim 

 milk, buttermilk, and whey necessary to produce 1 lb. of 

 pork are also given.

* Coburn takes as a comparative basis 4 lb. of grain or 1 5 lb. of green clover 

 or lucerne as producing 1 lb. of pork. 



It must be pointed out that while the grain foods men- 

 tioned in section A of the table may be fed alone or in 

 combination and form the sole food of the pig, the root and 

 fodder crops (section B) can only be employed in conjunction 

 with cereal food, for they form little more than a maintenance 

 ration when fed alone. While, therefore, the figures in 

 section A may be taken as approximately real, those in 

 section B are theoretical, and show the comparative values 

 for pig-feeding of the seven crops mentioned. When fed, in 

 conjunction with a suitable quantity of grain, the root and 

 fodder crops will, as already stated, form a useful portion of 

 the ration, and may be expected to produce pork at the 

 approximate rate mentioned in the third column.
