Get more parasite coverage this fall
Four tips for getting the most parasite control
By Mark Alley, DVM, managing veterinarian, Zoetis
When you are deworming your cattle this fall with an oral drench dewormer, focus more on the amount of parasite control you get from the product and less about the dosage volume.
Don’t fret higher dosage volume.
A higher volume dose isn’t a bad thing for parasite control with oral drench. Benzimidazole products (e.g., Valbazen® Suspension) work best through prolonged exposure of parasites to “toxic” concentrations of dewormers.1,2 With a large rumen/abomasum, a higher volume dose is more likely to expose parasites to the active ingredient and help improve product efficacy.
Why you should fret about incomplete coverage.
With some benzimidazole oral drench products, you’re looking at about 25% to 47% less parasite and larval stage coverage.3 If you select certain oral drench products, you will also miss important control of liver flukes, both important species of tapeworms (Moniezia expansa and M. benedeni) and parasitic roundworms (Nematodirus spathiger).
These internal parasites are responsible for numerous problems, including suppressed appetite and reduced feed intake. Reduced feed intake leads to less nutrients, which can hinder an animal’s immune system and cause them to respond poorly to vaccines and disease challenges.
Here are more tips to help you get the most parasite control from your oral drench dewormer this fall:
1. Collaborate with your veterinarian each year, so you have a solid deworming program that is best suited for your herd.
2. Reduce feed or fast the animals prior to administration. This slows the rate of passage in the rumen, giving the product more time to work.1,2
3. Weigh the animals so you are administering the most accurate dosage.
4. Deworm based on your geographic location. Timing varies so you’ll need to work closely with your veterinarian.
Parasites are complicated and found in all forage situations. These tips can help improve your success this fall and remember to look for an oral drench product with the most coverage against damaging internal parasites.
