Fattening Pigs in the Dry Lot

Corn and tankage versus corn, shorts, and tankage. 



Although tankage is proved to be a more eflBcient 

 supplement to corn than shorts or middlings, and more 

 economical with the usual prices, a combination of tank- 

 age and shorts is superior to tankage alone. Three experi- 

 ments conducted by Weaver at the Missouri Experiment 

 Station and three by Wright at the Kansas Station give 

 rather conclusive evidence in support of this. In all 

 these tests the two rations were fed to fattening pigs in 

 the dry lot, and the experiments closed when approximate 

 market weights had been attained. The summarized 

 results of these six experiments, which covered an average 

 period of 63 days, are shown in Table CVI.

The pigs fed an average of 25 per cent of shorts with 

 corn and tankage gained daily .23 of a pound faster than 

 those not receiving shorts. In each of the six tests the 

 consumption of feed was greater and the gains faster 

 with the former ration. In the corn and tankage ration, 

 a total of 451.66 pounds of feed was required to pro- 

 duce 100 pounds of gain, and in the corn, shorts, and
