It includes calves that arc born healthy as well as (hose that are born weak. In an attempt lo got more in- formation on the cause and con- trol of the weak calf syndrom, the veterinary services division contacted vcl erinari ans in the United Slates where a similar problem as reported two or three years ago. However, results from these inquiries were termed disap- pointing. Most o! the veterin- arians felt that the calf lossos they h ad been involve! with had been caused by stich things as tlic hard winter, limited feed supplies, iod ine def icaenox-s, leptospi rosis, virus infections and other diseases. A questionnaire was then sent to all veterinarians and a num- ber of department agricul- ture personnel in Alberta to get their views on the calf syndrome. Of the veterinarians who re- plied, two-thirds said that some- thing like this syndrome liad oc- curred in their areas, and that its incidence was higlier last year than previously. Twe n ty three herds wero then selected for intensive in- vestigation and the problem discussed with their owners. Although in many cases a specific diagnosis was not pos- s i b 1 e, information collected from the ranchers, their veteri- narians and veterinary services INSTALLATIONS NOW IN OUR NEW LARGER PREMISES!

Calf sccurs affected 10 herds; selenium responsive affected four herds; prenatal viral infec- tion affected four herds; mrfri- t ional problems thrco lYerds; and genetic problems af- fecled two herds. calf scoiir cases in the first category did not appear to be any different from (hose in other herds, the possible! exception that more of the ani- mals suffered a sudden onset the septicemic type, soys Dr, Vance. Often the calves died twfore diarrhea was noticed. In at least one case, a virus infec- tion was suspected of being mainly responsible for t scotrrs. In the selenium respimsivo category most of tire tests showed detinile evidence o{ white muscle disease. The calves responded lo t reatmcnt with .setenimivvitambi 15, The cases designatcd as pre- natal infection were put into Oiis category because th-ero was evidence that some infec- tion Irad throtigli coivs when they were stili carrying calves. In some herds viiiis in- fection was diagnosed in abort- ed calves. In other cases lha diagnosis was strictly specula- tive. The cows in the three herdg placed in (lie nutritional cate- gory were in pioor condilicm as they calved. Many of tlie calves were so weak at birth Hint they never nursed. Enei'gy, protein and possibly vilamin A deficien- cies were most likely to havo caused the trouble. One of the herds in Ilie gen- et ic category had semen from several of flic new tfeof brtxxis on Hereford heif- ers. Many difficult calvirgs wero cxperiencwl and losses En c-olves born alive were quite high. The second in this category had many coses of sis, a joint ailment. Based on information assem- bled so far, Dr. Vance feels that of this kind could bo partly avoided by the following precautions: having all feeds analyzed and a balanced raticn worked out. Tlten feeding the jvition as recommerided; checking tlw local veterinarian on the need for wnite masclo discnse preven- tion; and vaccinating cows with T. B.Tl- vaccine when they ara open. Use of this vaccine shxild Ix; checked with a veterinarian. Although investigations into the weak calf syndrome still leave much to be cJe.siicd, Dr, Vance intends to carry out fur- thcr investigations on farms which experience problems dur- ing Llie coming calving season. He out that n great deal more needs (o known about this condition it can solved. Prices down classed as good sold for average during Feb- ruary Ihis year, down slightly from last year.
