Preparation of Feeds

1912 to determine the effect of shelling or grinding corn 

 as. influenced by the age or weight of the pigs fed. One 

 group of pigs was fed dry ear-corn, another dry shelled 

 corn, and a third corn-meal wet by pouring on water at 

 feeding time. Each ration was balanced by feeding tank- 

 age once daily in the form of a thin slop. In two of the 

 experiments a small quantity of shorts was given with 

 the tankage. The trials were conducted under dry lot 

 conditions, the individual experiments being continued 

 until all the pigs had attained approximate market 

 weights. The average initial weight of the three lots of 

 pigs fed in the different tests was as follows, — 52#, 56#, 

 86#, 102#, 156#, 159#,211#,and 218#, this variation being 

 for the special purpose of affording a means of studying the 

 effects of weight on the economy of the two methods of 

 preparation. The average results of all eight experi- 

 ments, shown in Table CLXII, will first be considered.

 Ear-Corn for Fattening Pigs 



(Av. 8 Exps.) 



The averaged results show that less feed was required 

 for a unit of gain with ear-corn than with shelled corn,
