- Internal Parasite Control in Louisiana Beef Cattle
Download
Controlling internal parasites in grazing cattle is important for cattle health and welfare and can have a significant positive return on investment. However, there is increasing concern about resistance of cattle parasites to dewormers (anthelmintic resistance or AR) and the ability of cattlemen to continue to have cost-effective parasite control. Anthelmintic resistance is a very complex and serious issue, and the extent of AR varies from ranch to ranch. Cattlemen need a basic understanding of parasite biology and control measures so they can work with their veterinarian to develop parasite control programs that balance the short-term economic benefits of deworming with the long-term impact of anthelmintic use on resistance. This fact sheet outlines basic background knowledge and steps to take to develop a parasite control program in beef cattle with the herd veterinarian.
