1 Disease risks and disease management during weaning
KJ Whitman, DVM, MS

2 Spring calving herds-beef cattle cycle
Breeding Branding Weaning Pre-calving What are the options for where this calf goes? What are the disease risks around weaning time and at entry into the feedlot? How can those disease risks be mitigated? What are the health, production, and economic impacts? WINTER SPRING FALL SUMMER

3 Overview of the (traditional) weaning process

4 Many Weaning Strategies
Type Immediate Fence-line Nursing aversion tools Timing Health considerations Other goals

5 Common Diseases of Calves at Weaning
Risk Categories Disease Outcomes Low-Ultra High How do we determine this? Preconditioning status Timing of routine procedures Comingling and shipping risk Planning and management Risk vs. Reward Respiratory Upper and lower Digestive Lameness Other

6 Direct to feedlot: Disease
Risks Diseases Stress of weaning and shipping Comingling-naïve animals Exposure to new environment Reduced feed consumption Previous management strategies BRD Coccidiosis Acidosis/diarrhea Bloat Behavior

7 Backgrounding/Stocker: Disease
Risks Diseases Stress of weaning and shipping Comingling Exposure to new environment Pastures with toxic plants Other pasture pathogen exposure Cycling females BRD Bloat IBK Coccidiosis Footrot Plant toxicity Other Parasites Precocious pregnancy

8 Treatment Protocols-First things first….
Disease identification Diagnostics Economic and outcome decisions Epidemiology Is there truly a problem? Appropriate therapy Effective (and legal) treatments OUTBREAK INVESTIGATION

9 Treatment/Therapy Options
Antibiotics Analgesics Anthelmintics Nutritional therapy Supportive therapy Surgical/corrective procedures

10 Medication Options http://www.farad.org/eldu/eldumain.asp
