Lethbridge Herald, The (Newspaper) - June 27, 1972, Lethbridge, Alberta 12 THE LETHBKIDGE HERAID _ Tunday, June 27, Hog disease brings warning from officials it so per cent of Ihe sows or gilts of any hog operation are having litters of small, brown, mummifled pigs, or if there is a high percentage of these pigs in one or more litters, a virus disease known as S.M.E.D.I. may be present. Dr. G. G. Klavano, microln- ologist at the Alberta veterin- ary services laboratory in Ed- monton, reports that S.M.E.D.I. (Stillborn, Mummification, Em- bryonic Death and Infertility) was first noted in this province as a definite disease in 1968. Since that time it has occurr- ed sporadically in swine herds here. The odd mummified pig appears in most normal herds from time to time, but very seldom is there more than one in a litter. Dr. Klavano states the fol- lowing as a typical case history of S.M.E.D.I. A breeder with a 'closed" herd introduces a pig or pigs carrying the virus from another herd. If contact with a "pregnant female in the breed- er's herd occurs early in the gestation period, the develop- embryos may die and be reab- sorbed. However, if the contact is made when the embryos are well developed, the pregnancy will continue to term, and the sow will farrow a lifter of pig- lets that vary in size from that of a mouse to a normal pigleL Most will be mummified or show signs of mummification. Usually litters of mummified pigs continue to appear for two or three months and them sud- denly stop, According to Dr. Klavano, sows that have farrowed these litters are often hard to settle on their next breeding. lie rec- ommends breeding them twice and then sending them to slaughter U they return for a third service. However, if there are no breeding problems, he advises keeping these sows be- cause they are probably im- mune to subsequent attacks of the S.M.E.D.I. virus. Dr. Klavano 'there are still many unknowns connected with S.M.E.D.I. "We do not know, for example, how it is transmitted, but we feel it is by direct he said, "We do not know how long the immunity lasts afler the disease has occurred, but some feel it may be for as long as two or three years. However, we feel that we have enough knowledge about S.M.E.D.I. to make some recommendations that should keep this devasta- ting disease from spreading to other Alberta herds." Keep a closed herd. Since it is still not known how long an animal may remain a carrier, new additions to the herd should be limited to as few as possible, and an attempt made to find out the health history of the herd from which they come. A closed herd is a good practice for keeping out all swine disease. Keep new additions to the herd isolated, and avoid any contact between them and sows or gilts that are about to be bred or are already pregnant. Keep the herd isolated. There is no vaccine or vaccination and your nearest veterinary, that will prevent S.M.E.D.I. services laboratory if S.M.E. Contact your veterinarian D.I. occurs. Farm count drops The number of farms in Al- berta declined by 9.7 per cent from to between 1966 and 1971 according to a re- cent agricultural statistics re- port released by the Alberta department of agriculture In co-operation with Statistics Canada. However, total farmland acreage in the province in- creased by just over one per cent from acres in 1968 to acres in 1971. The report shows that the av- erage acreage per farm in Al- berta increased by. almost 12 per cent from 706 acres to 790 acres during the five year pe- riod. Tor Canada as a whole, the 1971 census of agriculture counted 15 per cent fewer farms in 1971 than in SEIF- MAINTAINING PRECLEANER PRECLEANER _ STOPS The greatest source of engine failure fine dust if Engine life is greatly Increased Oil Both or Dry Cartridge Cleaners last over 6 times longer if Equally harmful water and snow are completely removed if You have no moving parts, fillers, etc. to maintain if Only an occasional check of air filler U necessary When an RW PRECLEANER is installed ahead of oil bahS or dry cart- ridge cleaner, 95% of overage dust It eli- minated, AVAILABLE NOW AT 249 Stafford Drivo 803 46lt> Avc S E.
