Feeding and Care of Pigs

Corn alone versus corn and forage. 



In all of the experiments summarized in Table XXXIII, 

 the pigs in the dry lots were fed balanced rations. If corn 

 alone had been given in both the forage and dry lots, the 

 value of the forage in each case would have been greatly 

 increased. To illustrate the high valuation of the forage 

 crop when calculated on the basis of the cost of producing 

 gains with corn alone in the dry lot, the few available 

 experimental results are summarized and presented in 

 the following table.^ The value of these forage crops as 

 sources of protein and mineral matter, or as means of 

 balancing a ration of corn alone, is, also, strikingly shown 

 by these results.

Although the experimental work presented in this 

 table is too meager to make generalizations possible, and 

 although the poor returns from corn alone are extreme, 

 the results are nevertheless suggestive. As would be 

 expected, the value of the forage crops in these experi- 

 ments was much greater than in those in which balanced
