Description/Abstract:
THE EFFECTS OF NUTRITION, MANAGEMENT, AND DISEASE ON THE PRODUCTION OF RANGE SHEEP IN IRON COUNTY, UTAH AND LINCOLN COUNTY, NEVADA ARE DISCU SSED. FOUR HUNDRED FIFTY RANGE EWES WERE BORROWED FROM TWO SHEEP OPER ATIONS IN THE AREA OF CEDAR CITY, UTAH. THEY CONSISTED OF EQUAL NUMBE RS OF SIX AGE GROUPS: LAMB, 1,2,3,4 AND OVER 4 YEARS. THE SHEEP WERE HANDLED IN THE USUAL MANNER EXCEPT THAT OUT OF TEN GROUPS, NINE GROUP S WERE EXPOSED TO EXPERIMENTAL FEEDING METHODS AND NUTRITIONAL SUPPLE MENTS OF PROTEIN AND PHOSPHORUS. ONE GROUP WAS USED AS A CONTROL GROU P. IT WAS FOUND THAT THE SUPPLEMENTATION PRODUCED BENEFICIAL EFFECTS, AND IN ALL THE MEASURES USED IN THE EXPERIMENT, A TREATED GROUP ALWAYS GAVE BETTER RESULTS THAN THE CONTROL GROUP. DIFFERENCES IN RESULTS D UE TO THE USE OF SHEEP FROM TWO DIFFERENT OWNERS WERE FOUND TO BE GREA TER THAN THE DIFFERENCE DUE TO TREATMENTS. THIS IS EXPLAINED AS THE D IFFERENCE IN THE MANAGEMENT OF THE SHEEP BY THE OWNERS TO BEING TAKEN FOR THE FEEDING EXPERIMENTS. A SURVEY OF DISEASE PROBLEMS WAS ALSO MA DE DURING THE WINTER GRAZING SEASON OF 1954-55. TWENTY FLOCKS OF SHEE P WERE OBSERVED AND THEIR CONDITIONS DIOGNOSED. THREE CHARTS ARE INCL UDED TO GIVE A GENERAL VIEW OF THE CONDITIONS FOUND ON AUTOPSIES OF AD ULTS AND YOUNG LAMBS, AND ON CLINICAL EXAMINATION. THIS STUDY CONCLUD ES THAT DISEASE IN THE SHEEP POPULATION OF SOUTHWESTERN UTAH AND SOUTH EASTERN NEVADA IS THE CAUSE OF THEIR GREATEST DEATH LOSS. MUCH OF TH E LOSS, IT IS SUGGESTED, COULD BE PREVENTED BY IMPROVING MANAGEMENT PR ACTICES AND LEVEL OF NUTRITION.
