Pork Production 



Balancing the corn with linseed-oil meal had the effect 

 of enhancing the palatability of the ration, increasing 

 the consumption of feed, and in stimulating more rapid 

 gains. The pigs fed linseed-oil meal with their corn 

 were on the average 50 pounds heavier at the end of the 

 average feeding period of 90 days. 



A unit of gain was also made on less feed. The feeding 

 of 54.42 pounds of linseed-oil meal had the effect of saving 

 175.70 pounds of corn. With corn worth 56 cents a, 

 bushel, this would mean a valuation of $64.56 for a ton 

 of linseed-oil meal when fed under the conditions of these 

 experiments. An exaggerated value, however, is given 

 to linseed-oil meal by this method of determination. A 

 more reliable test is obtained by comparing it with other 

 protein supplements of the same class. 



Linseed-oil meal versus tankage. 



On page 258 is given a summarized statement of the 

 results of eight practical feeding experiments in which 

 rations of corn and linseed-oil meal were compared with 

 those of corn and tankage. As determined by the amount 

 of feed required to produce 100 pounds of gain in these 

 experiments, the money value of linseed-oil meal would 

 be as shown in Table CXI.
