Why Biosecurity Matters for Your New Highland Herd
Bringing Highland cattle to a new property is exciting, but it also introduces disease risks. A solid biosecurity plan protects your investment and ensures a healthy start. Diseases like bovine tuberculosis, Johne’s disease, and internal parasites can linger in soil or spread from neighboring livestock. Proactive measures are key.
Pre-Arrival Property Assessment
Before your Highlanders arrive, inspect the land and facilities. Look for signs of previous livestock: old manure, contaminated water sources, or fencing that could harbor diseases. Test soil for pathogens like Mycobacterium avium subspecies paratuberculosis (Johne’s). If possible, allow a 30-day rest period after removing other animals to break parasite cycles.
Sourcing Healthy Cattle
Choose reputable breeders who follow biosecurity protocols. Request veterinary health certificates and test results for common diseases. Quarantine new arrivals for at least 30 days in a separate paddock at least 20 feet from existing cattle. Monitor for symptoms like coughing, diarrhea, or weight loss during this period.
Quarantine and Testing Protocols
Establish a dedicated quarantine area with its own water trough and feeding equipment. Avoid sharing tools or footwear. Test for bovine viral diarrhea (BVD), bovine leukemia virus (BLV), and neosporosis. Work with a vet to create a vaccination schedule for clostridial diseases, leptospirosis, and respiratory pathogens. Consider fecal testing for liver fluke and lungworm.
Managing Wildlife and Domestic Animals
Deer, elk, and other wildlife can transmit diseases like tuberculosis and leptospirosis. Secure fencing (at least 5 feet high) to reduce contact. Keep dogs and cats away from feed and water sources—they can carry Neospora and other parasites. Control rodents and birds that contaminate feed.
Biosecurity Practices for People and Equipment
Use dedicated boots and coveralls when working with different cattle groups. Disinfect boots with a 10% bleach solution or commercial product between quarantined and main herds. Clean and disinfect trailers, feeders, and waterers after each use. Restrict visitor access and log all deliveries.
Creating a Disease Response Plan
Prepare a written plan for disease outbreaks. Include isolation steps, emergency contact numbers for your vet and state veterinarian, and procedures for carcass disposal. Regularly review and update the plan with your herd health records.
Long-Term Monitoring
Conduct monthly health checks, including body condition scoring and fecal exams. Keep records of treatments and test results. Re-test for Johne’s and BVD annually. Rotate pastures to break parasite cycles. A biosecurity plan isn’t one-time—it’s an ongoing commitment.
