EFFECTIVENESS OF TWO PREVENTIVE CONTROLS FOR CONFINED CATTLE RESPIRATORY DISEASES

Abstract

CATTLE RAISED IN INTENSIVE CONFINEMENT SYSTEMS ARE AT GREATER RISK FOR THE DEVELOPMENT OF RESPIRATORY DISEASES DUE TO THEIR EXPOSURE TO STRESSORS SUCH AS THE TRANSPORT, AGGLOMERATION AND MIXING OF ANIMALS FROM DIFFERENT ORIGINS, ENVIRONMENTS AND CLIMATIC VARIATIONS. THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE THE SANITARY VIABILITY OF INFORCE 03�® AND CATTLEMASTER 4�® VACCINES IN THE PREVENTIVE CONTROL OF PNEUMONIA IN CATTLE SUBMITTED TO INTENSIVE FATTENING SYSTEM. THE EXPERIMENT WAS CARRIED OUT AT FAZENDA VERA CRUZ, FROM THE OTAVIO LAGE GROUP, LOCATED NEAR GO 080, KM 65.5, GOIAN�SIA MUNICIPALITY, GOI�S STATE. FOR PREVENTION OF PNEUMONIA. ONE BATCH RECEIVED ONLY CATTLEMASTER 4�®, AND ANOTHER BATCH VACCINATED WITH INFORCE 03�®, WHILE A THIRD BATCH RECEIVED BOTH CATTLEMASTER 4�® + INFORCE 03�® COMBO VACCINES. THE INFORCE 03�® PNEUMONIA VACCINE PROMOTED HIGHER LIVEWEIGHT GAIN, AVERAGE DAILY GAIN, DEADWEIGHT, DEADWEIGHT IN @, FINANCIAL RETURN PER ANIMAL (P <0.01%). THINKING ABOUT THE DEAD WEIGHT, THAT IS, THE ANIMAL YIELD IN @ WAS 15% HIGHER THAN THE OTHER TREATMENTS, AND PROMOTED A RETURN OF R $ 141,03 MORE THAN THE MAIN COMPETITOR (P <0,01%). THE INFORCE 03�® VACCINE STOOD OUT WITH THE BEST RESULTS FOR LIVE WEIGHT GAIN, AVERAGE DAILY GAIN, DEAD WEIGHT, ARROBAS DEAD WEIGHT (@) AND GAIN IN R $ PER ANIMAL. REGARDING BATCH MORBIDITY, THE BEST RESULTS WERE OBTAINED WITH COMBO AND INFORCE 03�®.
