Calves treated with EPRINEX Pour-On gained significantly more weight than calves treated with doramectin 1% injection.

Missouri: This 167-day trial compared the effect of treating naturally infected beef calves with EPRINEX Pour-On to treatment with doramectin 1% injection. One hundred and twenty (120) Angus calves approximately 6 to 8 months old and weighing 136 to 274 kg were allocated among three treatment groups, detailed below. Calf weights were measured 2 days before the start of the trial and regularly throughout the study, wh i ch ended on Day 167.

• Group 1 was left untreated as the Control group
• Group 2 received doramectin administered subcutaneously at 200 mcg/kg on Days 0 and 56
• Group 3 received EPRINEX Pour-On administered topically at 500 mcg/kg on Days 0 and 56

At Day 110, cattle treated with EPRINEX had gained 118.2 kg — significantly more (P< 0.05) than the 107.5 kg gained by animals treated with doramectin — and continued a weight gain advantage through the end of the trial. Cattle treated with EPRINEX gained 9.3 kg more than cattle treated with doramectin and 28.8 kg more than Controls.

At Day 110, Cattle treated with EPRINEX achieved significantly greater gain than those treated with doramectin and continued a weight gain advantage through the end of the trial.
