days overtime. When absolutely hairless and born alive they 

 may live a few hours after birth, but always die sooner or later. 

 They are characterized by thick, pulpy necks, thick skin, no 

 squeal, and no vitality. 



The cause of the malady in both sows and young pigs is 

 goitre, and the remedy recommended is feeding the sow potas- 

 sium iodide throughout the period of gestation. It is recom- 

 mended to give the sow during her entire gestation period 10 

 grams (approximately one-third of an ounce) of potassium 

 iodide per 100 pounds of feed. It should be powdered to a meal 

 as fine as flour, and then mixed with 100 pounds of feed. It 

 had better be fed the entire gestation period, or at least the last 

 seventy-five days of gestation. 



The Montana Experiment Station recommends about half 

 the dose recommended above, fed for a period of sixty days. 



Special quack remedies should be avoided. Iodine does the 

 work cheaply and effectively, and is the only known remedy.
