Control of Nematodes and Arthropods

The timing of treatment of cattle with MLs in North America tends to be driven by other management activities. This is more predominant in North America than Europe or the subtropical climates because internal parasite infections tend to be mostly subclinical in nature as a result of low stocking densities and interruptions of transmission periods by very cold or very hot, dry weather in North America. Though the timing of treatment may not be optimal for parasite control, treatment is given when cattle are shipped, cows are pregnancy tested, calves are weaned, ear-tagged for flies or castrated, or stocker cattle enter a backgrounding operation or feedlot.
