Strategically Deworming Can Improve Early Conception in Beef Cattle

Treating cows can result in breeding back quicker and easier

The popular expression, “the sooner the better,” is a classic for a reason – because it rings true for so many situations in our lives. For instance: When a young boy breaks a window and is scared to confess the accident to his parents, usually the sooner he does, the better the situation will turn out. Or when a 4-Her has a woodworking project to begin and the fair is just around the corner, once again – the sooner the better.

Perhaps it’s a stretch, but the same notion can apply to a cattle producer practicing strategic deworming to maximize his herd’s potential.

An Iowa State University study shows that parasite control is the most economically beneficial practice for beef producers.1 But more specifically, producers who treat their cows – as well as their calves – for parasites may set themselves up for greater bottom-line success, even when cattle prices are down.

Why? Because when it comes to breeding back beef cows, the sooner the better.

Cows that conceive late calve late, and that can decrease weaning weights by as much as 40 or more pounds.2 Managing for conception should not only target ways to get cows to breed back, but breed back as quickly as possible.

Cade Coppenbarger, DVM, and practicing veterinarian in Davis, Oklahoma, is an avid supporter of treating cows for internal and external parasites, and knows that timing is everything when it comes to conception management.

“From personal experience and from talking with several veterinarians across the country, treating cows for parasites is imperative if producers want their cows breeding back sooner,” Coppenbarger says.

A cow’s peak lactation period occurs approximately 85 days after calving, and during that time, the cow also experiences a feed shortfall and a loss of body energy stores. This is the ideal time at which to breed back a cow,3 which increases the need for a parasite control program.

But cattlemen shouldn’t settle for just any parasite control program, Coppenbarger says.

Deworming cows results in fewer larvae eggs being deposited on the pasture for a period of time, depending on the product’s persistence. However, conventional dewormers only last for a short time – about 14 to 42 days. So even if cows are dewormed at turnout, the dewormer has worn off by the time parasite larvae reach their heaviest concentration.

Producers who want to get the most out of their efforts should contact their veterinarian to discuss the strategic deworming protocol that will best fit their operation’s needs. And, of course, the sooner the better.
