Why Faecal Egg Counts Matter for Highland Cattle
If you’re a Highland cattle owner, you may have heard about faecal egg counts (FECs) but wonder what they really mean. In simple terms, a faecal egg count measures the number of parasite eggs in a cow’s manure. This simple test helps you understand the parasite burden your animal is carrying, so you can make informed decisions about deworming. For Highlanders, which are known for their hardiness, FECs are especially valuable because they help you avoid over-treating with chemicals, saving money and promoting healthy gut flora.
How to Collect a Faecal Sample from Highland Cattle
Collecting a sample is easy and stress-free. You’ll need a clean plastic bag or container and a pair of gloves. Wait for the cow to defecate naturally – do not try to stimulate it. Using the bag as a glove, pick up a small amount (about a golf ball size) of fresh manure. Make sure it’s not contaminated with soil or old bedding. Seal the bag, label it with your cow’s name and the date, and refrigerate it until you can send it to a lab or test it yourself. Ideally, get the sample to the lab within 24 hours, as eggs may hatch and give inaccurate counts.
Understanding the Numbers: What Do FEC Results Mean?
Faecal egg counts are usually reported as eggs per gram (EPG). For adult Highland cattle, a count below 200 EPG is generally considered low, while 200-500 EPG is moderate. Above 500 EPG indicates a high burden that may require treatment. However, these thresholds can vary depending on the season, the cow’s age, and whether it’s a cow or a calf. Calves are more susceptible to parasites and may show clinical signs at lower counts. Always consult your vet to interpret results in context.
When to Test Your Highland Cattle
Regular testing is key to effective parasite management. For most herds, testing two to four times a year is recommended – typically in spring, summer, and autumn. In warmer climates, more frequent testing may be necessary. Additionally, test after introducing new animals to the herd, or if you notice signs of parasite infection such as weight loss, diarrhoea, or a rough coat. By testing strategically, you can avoid unnecessary deworming and target treatments only when needed.
Factors Affecting Faecal Egg Counts in Highlands
Highland cattle have unique characteristics that affect their FECs. Their long hair and thick hide may influence fly populations, but the primary factors are age, nutrition, and grazing management. Young calves often have higher counts due to immature immunity. Poor nutrition can weaken the cow’s immune response, leading to higher egg counts. Overcrowded pastures and grazing on contaminated swards increase reinfection. Conversely, Highlanders’ natural hardiness and browsing behaviour may result in lower parasite loads compared to more intensively bred breeds.
How to Use FECs to Create a Deworming Plan
Once you have FEC results, you can tailor your deworming strategy. If counts are low, you might skip treatment and retest later. If counts are high, you’ll need to select an appropriate anthelmintic, but be aware of resistance. Rotate between drug classes and always dose accurately based on weight. After treatment, retest after 10-14 days to ensure the treatment was effective. This targeted approach, often called ‘smart deworming’, is not only better for your cows but also helps preserve drug effectiveness for the future.
Integrating FEC Testing with Other Management Practices
Faecal egg counts are just one tool in your parasite management toolbox. Combine them with pasture rotation, co-grazing with sheep (which can break parasite cycles), and maintaining good nutrition. Also, keep your pastures well-drained to reduce moisture-loving larvae. Regular FECs help you monitor the success of these practices. By integrating FEC testing into your routine, you’ll keep your Highland herd healthy and productive while reducing reliance on chemicals.
Common Mistakes to Avoid in Faecal Egg Counting
When collecting or handling samples, a few mistakes can ruin your results. Using an old sample that’s dried out or frozen can give falsely low counts. Mixing manure with soil can dilute eggs. Not refrigerating the sample allows eggs to hatch, making counts inaccurate. Also, be aware that some cows have intermittent egg shedding, so a single sample might not be representative. Taking samples from a few animals in a group can give a better picture than testing just one.
Frequently Asked Questions
Q: How often should I test my Highland cattle?
A: At least twice a year, but more often in high-risk periods or if you’ve had issues.
Q: Can I use a home testing kit?
A: Yes, there are simple kits available. But for accurate results, it’s best to use a certified lab.
Q: Do Highland calves need special attention?
A: Absolutely. Calves are more vulnerable, so test them more frequently and consider treating them separately.
Q: Will FEC testing cost me more time and money?
A: It may initially, but it saves money in the long run by avoiding unnecessary deworming.
Final Thoughts on Faecal Egg Counts
Faecal egg counts are a powerful, cost-effective way to manage parasites in your Highland cattle. They give you the data you need to decide when to treat, what drugs to use, and how effective your management is. By embracing this practice, you’re not only keeping your cows healthier but also contributing to the fight against anthelmintic resistance. So next time you’re out in the pasture, take a moment to collect a sample – it’s a small step that makes a huge difference.
