Stress Factors Heat Cold Dust Dampness Injury Fatigue Dehydration Hunger Anxiety Irritant gases Nutritional deficiencies Surgery Causes of BRD
Viral Agents PI3 IBR BVD BRSV Adenovirus Rhinovirus Herpesvirus IV Enterovirus MCF Reovirus Causes of BRD
Bacteria • Pasteurella Hemophilus Other Causes of BRD
Nasal and eye discharges • Coughing, fever, decreased appetite • Varying degrees of breathing difficulty, depression, droopy ears Clinical Signs
Management • Vaccines Prevention of BRD
Eliminate stress factors where possible • Recognize the “Critical Period” for disease detection (3 weeks that follow weaning; placing on feed; shipping of cattle) Prevention of BRD (management)
Avoid co-mingling cattle from different sources during critical 3-week period • Keep new cattle close to feed and water • Don’t over crowd (especially early in feeding period) • Control dust and mud Prevention of BRD (management)
IBR(red nose) • PI3(parainfluenza) • BVD(bovine virus diarrhea) • BRSV(bovine respiratory virus) • Pasturella(major cause of shipping fever) • Hemophilus Somnus(other agent involved with shipping fever) Prevention of BRD (vaccines)
