Description/Abstract:
THE THIRD PROGRESS REPORT ON RESEARCH BY THE UTAH STATE AGRICULTURAL C OLLEGE ON THE EFFECT OF NUTRITION ON RANGE SHEEP DIVIDES THE WORK INTO THREE PHASES. PHASE I DEALS WITH VETERINARY RESEARCH ON DISEASES AFF ECTING THE NERVOUS AND LYMPHATIC SYSTEMS AND THE SKIN. RESULTS FOR PH ASE I SHOW THAT A) THE ATTEMPT TO FIND THE CAUSE OF IDIOPATHIC MENINGO ENCEPHALITIS OCCURRING IN SOUTHEASTERN NEVADA WAS UNSUCCESSFUL; B) ATT EMPTS TO PRODUCE A TOXIN FROM CASEOUS LYMPHADENITIS WERE ALSO UNSUCCES SFUL, AND C) PRELIMINARY STUDIES SHOW THAT A TESTED SKIN DISEASE WAS C AUSED BY THE CHYMOPTERUS WATSONII PLANT FOUND ON THE RANGE. PHASE II RANGE STUDIES DEAL WITH THE EFFECT OF RANGE CONDITION AND VIGOR OF PLA NT UPON THE NUTRITIVE VALUE OF THE FORAGE. TWO RANGES IN DIFFERING CO NDITIONS (GOOD AND FAIR) WERE ANALYZED FOR NUTRIENT CONTENT. SPECIFIC PLANTS WERE ALSO GIVEN A SEPARATE TESTING. SHEEP DIETS WERE ANALYZED OVER THE WINTER SEASON AND DURING VARIOUS PERIODS. IT WAS FOUND THAT PLANTS ON RANGES IN POOR CONDITION MAY OR MAY NOT HAVE SIGNIFICANT DI FFERENCES OF AVAILABLE NUTRIENTS COMPARED TO RANGES IN BETTER CONDITIO N. PHASE III OF THIS REPORT STUDIED THE LEVEL OF NUTRITION IN RANGE E WES AS IT AFFECTS BODY WEIGHT, LAMB CROP AND WEIGHT AND QUALITY OF WOO L. THE 849 TEST ANIMALS WERE DIVIDED INTO GROUPS BY AGE, OWNER AND FE ED TREATMENT, AND WERE FOLLOWED THROUGH A WINTER SEASON WITH PERIODIC WEIGHINGS. IT WAS FOUND THAT NO SIGNIFICANT DIFFERENCES OCCURRED FOR FEED TREATMENTS, PROBABLY DUE TO GOOD WEATHER CONDITIONS, EXCELLENT C ARE BY THE HERDER AND THE GENERAL AVAILABILITY OF RANGE FORAGE DURING THE SEASON. DIFFERENCES DID OCCUR BY AGE.
