Optaflexx Research Brief 75 Effects of Optaflexx on Performance and Carcass Characteristicsin Finishing Heifers: 16-trial SummaryElanco Study No. T4VUS130001Study overviewA meta-analysis of 16 trials was conducted to quantify the effects of Optaflexx dose level on performance and carcasscharacteristics in finishing heifers.Key study results Compared to the control, Optaflexx fed at 200 mg/hd/d:- Improved feed efficiency by 12.5%- Increased live weight gain by 11.9 lbs- Increased hot carcass weight (HCW) by 9.4 lbs- Increased dressing percent by 0.2 units Compared to the control, Optaflexx fed at 300 mg/hd/d:- Improved feed efficiency by 18.8%- Increased live weight gain by 17.8 lbs- Increased HCW by 14.1 lbs- Increased dressing percent by 0.3 unitsBackground informationTRIAL DESIGNMATERIALS AND METHODS Trial selection criteria- Experimental unit was pen or lot- Negative control and at least one Optaflexx treatment- On-label use for dose and duration- Period performance data (28 to 42 days) A total of 16 studies met selection criteria Total head — 12,342- Control: 5,387 hd- 100 mg/hd/d Optaflexx: 172 hd- 200 mg/hd/d Optaflexx: 5,139 hd- 300 mg/hd/d Optaflexx: 1,644 hd Research conducted in 8 states Initial weight ranged from 1,015 to 1,267 lbs Final weight ranged from 1,097 to 1,362 lbs Hot carcass weight ranged from 638 to 813 lbs Average duration of Optaflexx feeding was 32.3 daysSTATISTICS Data were analyzed in SAS using mixed effects regressionmodels with Optaflexx intake (mg/hd/d) as the primarypredictor The meta-analysis used a regression model that inverselyweighted each study to its variation — the more variationthere was in a study, the less weight the study was givenin the analysis Differences were deemed statistically significant if P 0.05Study resultsTable 1.
