Manage disease risk and weight variation with arrival metaphylaxis

Risk assessment

To effectively mitigate bovine respiratory disease (BRD) with metaphylactic program, it is critical to evaluate both the potential risk of disease and weight variation of the cattle in order to choose the right dosage. 

Micotil® (tilmicosin injection) Flex Does provides a dose range of 1.5 to 3 mL/cwt, meaning you can adjust your treatment dose to best match the needs of your cattle. 

"Factors such as unknown origin and vaccination history, commingling, adverse weather and plane of nutrition should all be considered when determining the most appropriate metaphylactic dosage," says Jacob Hagenmaier, D.V.M., Ph.D., Elanco technical consultant. "As more risk factors come into play, the more a higher dose may be warranted."

Choose the appropriate dosage

With over 25 years of proven results and use in over 100 million cattle, Micotil is the only macrolide for the BRD market approved with flexible dose range. This allows feedyards to not only adjust dose based on risk, but also to account for weight variation within a group of cattle. 

Elanco conducted two flex dose studies – one in Texas1 and the other in Colorado2 – comparing the efficacy of 3 vs. 1.5 mL/cwt dosage (20mg/kg and 10 mg/kg, respectively).

According to Hagenmaier, when combined, the findings of these studies are a good example of how an increased dose can be beneficial in certain groups of cattle where there is a higher risk of BRD. 

"Of these two studies, the BRD challenge was greater in the Texas study, based on the mortality levels observed. This is also the study where the 3.0 mL/cwt Micotil dose resulted in lower BRD pull rates compared to the low dose," he says. "But regardless of site and dose, BRD pull rates were decreased for all cattle that received Micotil, compared to the negative control."


Cattle receiving Micotil metaphylaxis also delivered higher net returns per head at closeout in the Texas study. There was a $126.02 and $86.60 advantage for cattle given 3.0 or 1.5 mL/cwt Micotil compared to non-treated controls, respectively.1

  • Choosing the right dosage based on disease risk and weight variation is important to consider when choosing a metaphylactic program

  • Micotil is a proven antibiotic that offers a flexible, cost-effective dose range for both metaphylaxis and individual pull-and-treat therapy, improving producers' bottom lines1,2

Micotil is indicated for the treatment of bovine respiratory disease (BRD) associated with Mannheimia haemolytica, Pasteurella multocida and Histophilus somni, and for the control of respiratory disease in cattle at high risk of developing BRD associated with Mannheimia haemolytica
