Farmers who buy feeder pigs from unknown sources take a chance on getting animals which are not only inferior but also diseased, according to Dr. C. D. Grinnells, professor of veterinary science at State College.
"Swine disease is on the increase. Promiscuous buying of feeder pigs from unknown sources has been a large factor in scattering disease," Dr. Grinnells said. A good hog man does not have time to roam the country marketing feeder pigs. He practices swine sanitation. Buy your pigs from him, even though you will have to look him up.
The farmer who buys pigs from an unknown source is likely to get an inferior product to begin with, he explained. In many cases the seller has not practiced good swine sanitation. By experience he has found that with his equipment and methods he can realize a greater return by selling small pigs. Often the animals carry parasites, and have low-grade infections and low resistance to disease.
These conditions, Dr. Grinnells continued, are aggravated by feed changes, lack of water, long hauls, and unsanitary conditions. The pigs are yarded, transported, fed, watered and often sold with pigs from a number of other sources. The opportunities to spread and to take in infectious materials are numerous. Conditions for the spread of disease are good.
Under these conditions, there is no vaccine that will prevent development of disease. Vaccines recommended to protect against a large number of infections are generally worthless and should not be trusted until tested and proved.
