# Cost-Benefit of Feeding BRD Vaccinated Calves

Beef cattle producers can use the following BRD Vaccination Cost-Benefit Calculator to evaluate the costs, risks and economic benefits of feeding calves that have been vaccinated for bovine respiratory disease compared to calves that have not.

## Step 1. Producer Information

Feeder Price (\$/lb)
Average Feeder Weight (lbs)
Average Cost of Gain (\$/day)
Number of Days on Feed
Expected Fed Cattle Price (\$/lb)

Instructions:

Step 1: Enter information in the yellow-shaded cells. It is suggested to keep the blue-shaded cell as the set defaults unless data is known.

Step 2: Scroll down to see Result Summary Charts.

Step 3: Scroll right to see the Decision Making Flow Chart comparing the results.

### Assumptions

– Assume feeders are vaccinated at cow-calf or backgrounding operations, hence the cost of vaccination is excluded in this feedlot level analysis.

– Typical morbidity (disease) incidence from BRD for vaccinated calves: 5%

– Typical mortality (death) incidence from BRD for vaccinated calves: 0.8%

– On average, estimate 11.4% of unvaccinated calves will get sick from BRD, and 4.2% will die; with best case scenario being only 6.8% get sick and 1.2% die, and worst case scenario 19.2% get sick and 13.3% die.*

– Average daily gain of cattle treated once is 0.15lb/day lower than cattle that were never treated (Schneider et al. 2009)

– Percentage of cattle graded AAA or better is 71% for cattle that were never treated, and 57% for cattle treated once (Schneider et al. 2009)

– Price discount on AA compared to AAA cattle is \$0.06/lb**

– Disposal cost for feeders died from BRD is \$200/head. (Canfax Survey)

* Based on Odds Ratio and Confidence Intervals for odds of morbidity and mortality for unvaccinated calves naturally exposed to BRD (Theurer et al., 2015)

** Estimated based on five-year average Canadian cutout and Alberta fed steer prices

## Step 3. Flow Chart

Are the purchased feeders vaccinated against Bovine Respiratory Disease (BRD)? What will happen to 300 feeders?

Yes

No

Unvaccinated calves have higher morbidity (disease) and mortality (death) risk than vaccinated calves.

About 5% calves get sick and need treatment, 0.8% die

Best Case Scenario:

6.8% get sick from BRD and need treatment, 1.2% die

Average Case:

11.4% get sick, 4.2% die

Worst Case Scenario:

19.2% get sick, 13.3% die

Death Loss: 3 head die due to BRD

4 head die due to BRD

13 head die due to BRD

40 head die due to BRD

The cost of death loss is 3899 or 13/head on all feeders

The cost of death loss is 5198 or 17/head on all feeders

Cost of death loss is 16894 or 56/head on all feeders

Cost of death loss is 51980 or 58/head on all feeders

Disease Prevalence: head are sick and need treatment
