Finding a few more hours in a day
Effective treatment that lasts for up to a week can reduce time spent pulling and re-treating
Pull. Re-treat. Pull. Re-treat. With the never-ending task list on any producer’s operation, spending less time pulling and re-treating cattle would be a welcome change.
“When producers aren’t spending as much time taking care of sick cattle, it can help free them up to focus on other aspects of the operation,” says Lee Bob Harper, DVM, managing veterinarian with Pfizer Animal Health. “There’s not a cattle producer I know who wouldn’t benefit from finding a few more hours in the day.”
One simple change producers can make to help free up more time is to use effective antimicrobials that allow for longer post-metaphylaxis intervals (PMIs) and post-treatment intervals (PTIs). A PMI is the amount of time one can confidently wait before pulling an animal for first BRD treatment following metaphylaxis. A PTI is the amount of time one can confidently wait before considering an animal a nonresponder following first BRD treatment.
“During this interval of time, the treatment should be working to provide effective levels of medication against a disease challenge,” Dr. Harper says. “Traditional practices may call for treatment administered about every three days until the animal recovers. Every re-treatment adds to the cost, reduces the profit margin on that calf and takes time away from other aspects of the operation.”
A product with a PMI or PTI of a week can provide effective treatment levels without the time traditionally spent pulling and re-treating multiple times, Dr. Harper says. However, not all products have the ability to continue providing effective treatment levels for a week, and producers should work with their veterinarian to find a product that works best for their operation.
DRAXXIN® (tulathromycin), for example, has been proven to be just as effective up to 14 days after the first treatment. In one study, 85 percent of cattle were treated successfully after a single injection with virtually no difference in mortality rates or average daily gain between a seven-, 10- or 14-day PTI.1
“Better understanding of the PMI and PTI of the treatments used for BRD can help producers carve out more time that may have originally gone toward pulling and re-treating,” Dr. Harper says. “If they can use a product that works well on the first injection, and works for a longer period of time, then producers can reduce the number of doses used overall.”
Important Safety Information: Do not use in calves to be processed for veal. A pre-slaughter withdrawal time has not been determined for pre-ruminating calves. Effects on reproductive performance, pregnancy and lactation have not been determined. DRAXXIN has a pre-slaughter withdrawal time of 18 days.
