Show Isolation Unit Plan. Prevents Diseases Farmers concerned with swine disease will be interested in an "isolation unit" plan for raising disease-free baby pigs. The units, as described in the American Journal of Veterinary Research, have already been used in viral infection research and in limited experiments on the elimination elimi-nation of disease from herds. The isolation units are tightly sealed compartments in which the air is changed constantly through sterile filters which screen out all the disease organism. Thus the baby pigs are raised in Infection-free surroundings. Experimenters say one possible use of these units Is to eliminate such diseases as atrophia rhinitis, brucellosis, erysipelas, tranmissi-ble tranmissi-ble gastroenteritis and dysentery from extremely valuable blood lines. Pigs from prize gilts could be raised in these units, to. break the plg-to-pig contact essential to the transmission of many swine diseases. In experiments so far, s colony of pigs has been raised to breeding age free from TGE and dysentery, two diseases which plagued the herds from which they were taken. The pigs raised in isolation were adapted to ordinary farm conditions condi-tions after they matured. |
