large areas to shift for themselves. jSTo prolonged feeding is practised in narrow 

 limits, but from birth to maturity they are pastured on alfalfa, oats, corn, rape, and 

 peanuts ... In striking contrast are tlie hogs slaughtered at three cities in 

 one of the leading dairy states, where there are a large number of co-operative 

 creameries and the raw skim-milk is fed." 



" Buyers for packing-houses are learning from bitter experience to avoid 

 sections of certain states, and two firms will not buy hogs from one state known to 

 be badly infected. In fact, many of the smaller packers in the Central "West buy 

 subject to post-mortem inspection, as a measure of self-protection." 



" It is known beyond all doubt that the majority of tuberculous hogs are 

 produced by the following causes : 



" 1. Feeding raw milk and slime from creameries." 



"2. Feeding hand-separated milk from tuberculous cows." 



" 3. Feeding behind tuberculous cattle.'" 



" 4. Feeding tuberculous carcasses." 



" 5. Feeding slaughter-house oflFal." 



" The danger of feeding hogs behind tuberculous cattle lies in the fact that 

 such cattle discharge enormous numbers of tuberculosis germs in their faeces." 



Symptoms Obscure. — '-The quotalions given show the importance of 

 this disease, and the need for the farmer to be on his guard. It is a contagious 

 disease and must be treated as such. The symptoms are not well marked, and a 

 hog may be badly diseased and show practically no clinical symptoms. If the 

 lungs are affected, the hog usually has a cough, and. if the digestive organs are 

 badly affected, there is generally indigestion, and general lack of thrift; but 

 similar symptoms may show themselves with other diseases, and it requires a great 

 deal of experience to diagnose the disease with certainty. 



Treatment. — Entirely preventive. Since the disease is usually communi- 

 cated to hogs through their feed, it is necessary to make certain that their feed 

 contains no germs. In dairy districts, the practice of sterilizing skim-milk, 

 buttermilk and whey is to be commended, because dairy by-products constitute the 

 main medium for transmitting the disease to hogs. Sanitary surroundings, pure 

 - feed, and fresh air are the feeder's main safeguards in connection with this 

 dangerous disease. 



IXDIGESTIOX. 



Indigestion in varigus forms is caused by mistakes in feeding. Over-feeding 

 and lack of exercise will sometimes bring on the trouble, or the feeding of swill 

 containing injurious substances, such as washing powders, ,is apt to cause de- 

 rangement. In the acute form it causes the animal a good deal of pain, causing 

 it to arch its back and give general evidences of suffering. In such cases it is well 

 to have a veterinarian prescribe for the trouble. 



The chronic form sometimes follows an attack of acute indigestion, causing 

 an unthrifty, stunted condition of the animal. Perhaps the best home remedy 

 is a dose of castor oil, followed by careful feeding upon easily digested feeds. If 

 the trouble is not relieved, a veterinarian should be consulted. 



Constipation. 



As mentioned in another place, constipation is most disastrous in the case of 

 pregnant sows, and is the result of too little exercise and too much concentrated
