Be strategic about deworming this year

Today, many cattle producers recognize that one-size-fits-all parasite control is not always the most effective approach. Rather than looking for a single solution, a strategic approach that considers geography and timing can help ensure that you get the results you expect from your deworming program.

“Using the right products at the right time is key,” says Jon Seeger, DVM, Pfizer Animal Health Cattle and Equine Technical Services. “Not just for good parasite control, but also when managing parasite resistance. Parasite resistance isn’t rampant yet in the United States, but it is a reality, and research has shown it can occur in cattle.

Properly planned parasite control can help producers improve overall health and productivity of their herd.”

Seeger recommends a more strategic approach to deworming, developed in conjunction with a local veterinarian.

“Producers need to take into account the geography, weather conditions, the type of operation and what they are trying to accomplish. What may work in one area might not work in another,” Seeger says. “Generally speaking, in the northern part of the country, spring deworming is the most critical time. Parasite control before turnout can help break the pasture contamination cycle and help keep cattle productive. Deworming again in the fall can help stop inhibited larvae from maturing into adults.”

Consideration for key factors affecting product efficacy — timing and controlling for specific parasites of concern in an area — are important when developing a strategic deworming protocol.

 “These factors can have an effect on the efficacy of the deworming products you are using and lead to a potential for parasite resistance,” Seeger says. “Timing and product type will accomplish different things, so work with your veterinarian to develop a program specific to your operation to get the most out of the deworming products you use.”

Along with this strategic approach, Seeger suggests deworming solutions to help manage your parasite control program like rotating between two different classes of dewormer, such as VALBAZEN® (in the benzimidazole class) and DECTOMAX® (in the macrocyclic lactone class). An example would be to utilize DECTOMAX Injectable Solution in the Spring and VALBAZEN in the Fall. 

“For the most effective parasite control, your strategic programs and the products you use need to be tailored to both regional and seasonal conditions and for the objectives that fit your operation,” Seeger says. “Implement a strategic deworming program with your veterinarian, based on the parasites prevalent in your area and the best timing for control.”

Important Safety Information for DECTOMAX: DECTOMAX Injectable has a 35 day pre-slaughter withdrawal period. DECTOMAX Pour-On has a 45-day pre-slaughter withdrawal period. Do not use in dairy cows 20 months of age or older. DECTOMAX has been developed specifically for cattle and swine. Use in dogs may result in fatalities.

Important Safety Information for VALBAZEN: Cattle must not be slaughtered within 27 days after the last treatment with VALBAZEN. Not for use in lactating dairy cattle. Do not administer to female cattle during the first 45 days of pregnancy or for 45 days after removal of bulls.
