Effects of Optaflexx® on Performance and Carcass Characteristics in Finishing Steers

       
Nathan Pyatt, Elanco beef technical consultant
  
    

A meta-analysis of 32 trials was conducted to quantify the effects of Optaflexx dose level on performance and carcass characteristics in finishing steers.

 

Key study results

 

Compared to the control, Optaflexx fed at 200 mg/hd/d improved feed efficiency by 14.5%; increased live weight gain by 15.0 lbs; increased hot carcass weight (HCW) by 13.5 lbs; and increased dressing percent by 0.5 units

 

Compared to the control, Optaflexx fed at 300 mg/hd/d improved feed efficiency by 16.4%; increased live weight gain by 22.5 lbs; increased HCW by 20.3 lbs; and increased dressing percent by 0.7 units

 

Key findings

 

Live and carcass weight gain increased as the dose of Optaflexx increased. The effects on carcass characteristics and USDA quality and yield grades changed with increasing doses of Optaflexx, resulting in slight shifts in yield- and quality-grade distributions.
