Heifers and steers treated with IVOMEC 1% Injection showed significantly more weight
gain than those treated with a benzimidazole.
Autumn Treatments: Five studies involved 111 mixed-breed cattle, including heifers
and steers. In each study, cattle were taken off pasture, matched by weight, and
allocated between two treatment groups:
- Group 1 received IVOMEC 1% Injection
- Group 2 was treated with a benzimidazole (BZ)
The cattle in each treatment group were housed in separate pens in each study; trial
duration was from 128 to 161 days. The cattle treated with IVOMEC had significantly
greater weight gain and average daily gain than those treated with a BZ (P<0.01).
Data from five studies comparing IVOMEC 1% Injection with a benzimidazole when treatments
were administred at housing.
