lactones provide longer duration control of parasites compared to benzimidazoles. • Benzimidazoles (white dewormers) are administered orally and act as a purge dewormer to internal parasites. These dewormers interfere with the microtubules of the parasites, which depletes the energy supply and eventually causes death of the parasite. Benzimidazole dewormers are usually in and out of the system within a couple of days. Dr. Kaplan adds that there is one caveat to combination treatment that producers should be aware of. “You don’t want to use combination treatment in a low refugia situation because it will promote rapid multiple drug resistance. The simplest way to not worry about this issue is to leave a group of animals untreated every time you deworm.” 3) Refugia - Refugia, where a percentage of the herd is selectively not dewormed, is recognized as the single most important factor in delaying the onset of parasite resistance. Leaving a portion of the parasite population in “refuge” from dewormers reduces the drug resistance selection pressure caused by the dewormer. “A common question I get asked is ‘how much refugia is enough?’ and unfortunately the answer is different for every producer,” said Dr. Kaplan. “The percentage of animals to leave untreated is totally dependent on the efficacy of the deworming product you’re using. This is where diagnostic testing and working with your veterinarian become especially important.” 4) Pasture management - Limiting
overgrazing, maintaining appropriate forage heights, and rotating pastures are all ways to reduce parasite loads in your pastures and to limit the number of parasites that get ingested by the cattle. “The way we manage our pastures and forages in terms of grazing has a significant impact on how much exposure to parasites our cattle are going to have,” said Dr. Kaplan. “If cattle are grazing on pasture that’s very low to the ground, they’re going to be ingesting many more parasites since most of the parasites are in the bottom two inches of the forage.” “Following sustainable deworming best practices will benefit your cattle herd and the future of our industry,” concluded Dr. Step. “Be sure to consult with your herd veterinarian to evaluate and customize a deworming program to your individual operation.” Reference 1 Paras K., Georgia M., Howell S., et al.

Clemson University Livestock Feed Ration Calculator We are excited to announce the development and release of a new online calculator for livestock feed rations. Please share this with any livestock producers you know. The web app calculates nutritional analysis and generates mix sheets for custom mixes of over 500 feed ingredients. You can even email the outputs to yourself so that you can print the results and/or revisit the site to make adjustments to batch weights. We hope you will find this new tool useful. If you have any questions on its use or suggestions for improvements, please let us know. Find the Livestock Feed Ration Calculator at https://precisionag. sites.clemson.edu/Calculators/Livestock/ RationCalculator/.
