but the prevention of hog cholera by the use of the serum treatment 

 has made possible an extensive trade in feeder pigs during recent years. 

 At most market centers there are dealers or traders who buy, vaccinate, 

 and sell feeder pigs. Federal regulations require inspection, vaccina- 

 tion, and either spraying or dipping in disinfectant prior to shipment 

 from the yards. 



The principal markets for feeder pigs are Kansas City, St. Paul, 

 St. Louis, and Fort Worth. The following table ^ gives the shipments 

 from the ten leading feeder pig markets and the total shipments from 

 68 markets during seven years:

Chicago, with 3,060 feeder pigs shipped, ranked 25th as a feeder 

 pig market in 1922. Omaha with 5,597 ranked 17th. 



Feeder pigs weigh from 50 to 150 pounds, with weights from 90 

 to 120 pounds most desired, and must be in thrifty, growing condition, 

 but not fat. They should show quality and evidence of good breeding, 

 and should be as uniform as possible in size and appearance. 



Roughs 



In this class we find hogs of all sizes that are very coarse, rough, 

 and lacking in condition. They are sometimes called "throw outs." 

 The pork from these hogs is used for the cheaper class of trade for both 

 packing and fresh meat purposes. They are frequently quoted in 

 market reports as "rough packing hogs." 



Stags 



Stags are hogs that at one time were boars beyond the pig stage 

 and were castrated. They sell with a dockage of 70 pounds. If they 

 are of good quality and condition and do not show too much stagginess, 

 they are included in the various classes of packing hogs. When they 

 are too coarse and staggy in appearance they are sold separately and 

 at lower prices.
