There are several ways to prevent cattle from developing anaplasmosis. Perhaps the most effective control measure is to feed low levels of chlortetracycline in the mineral supplement. In the past, many producers have used this method during the insect vector season, but it may very well pay to consider this as a year-round option. When fed on a year-round basis, lower levels of the drug can be utilized, and it is helpful in preventing other problems such as foot rot and pinkeye.
Another option is to give the whole herd oxytetracycline injections once per month during the insect season. Visit your veterinarian for specific recommendations and protocols effective in your area to prevent infections or to eliminate the carrier stage.
Another way to prevent anaplasmosis is to control insect vectors such as horse flies, which can transmit the disease between animals. Finally, wash all surgery instruments after use. In other words, don’t inject multiple animals with the same needle.
