When a Highland calf is born, its first meal is the most important one it will ever have. That meal is colostrum—the nutrient-rich first milk produced by the mother cow. For Highland cattle, a breed known for its hardiness and distinctive long hair, colostrum is even more critical due to their unique physiological needs. In this article, we’ll dive deep into why colostrum is vital for newborn Highland calves, how to ensure they get enough, and what to do if things go wrong.
What Is Colostrum?
Colostrum is the thick, yellowish milk produced in the first 24 to 48 hours after a cow gives birth. It’s packed with antibodies, proteins, vitamins, and minerals that a newborn calf needs to survive. Unlike humans, calves are born with a sterile gut and no immune system. Colostrum provides passive immunity, which protects the calf from infections until its own immune system kicks in.
Why Highland Calves Need Colostrum More Than Others
Highland cattle are a hardy breed, but their calves face specific challenges. They are often born in harsh, cold environments—even in snowstorms. Colostrum provides not only immunity but also energy and warmth. The high fat content in colostrum helps the calf maintain body temperature. Additionally, Highland calves have a lower birth weight compared to beef breeds like Angus, making them more vulnerable to hypothermia and infection. A good colostrum intake is their best defense.
The Golden Hours: Timing Is Everything
A calf’s ability to absorb antibodies from colostrum decreases rapidly after birth. The gut is most permeable in the first 6 hours, and by 24 hours, it can no longer absorb large molecules like antibodies. This is called passive transfer. For optimal protection, a Highland calf should receive 10% of its body weight in colostrum within the first 6 hours. For a 25 kg Highland calf, that’s about 2.5 liters (0.66 gallons).
Quality vs. Quantity
Not all colostrum is equal. High-quality colostrum has a thick, creamy consistency and a high antibody concentration (measured as immunoglobulin G or IgG). You can test colostrum quality using a colostrometer or Brix refractometer. A reading above 22% Brix indicates excellent quality. If a cow’s colostrum is thin or watery, consider supplementing with a commercial colostrum replacer designed for beef calves.
How to Ensure Your Highland Calf Gets Enough Colostrum
- Observe the birth: Watch to make sure the calf nurses within 2 hours. Some Highland calves are slow to stand; help them if needed.
- Check the udder: Ensure the cow’s udder is not swollen (mastitis) or the teats too large for the calf to suckle.
- Bottle or tube feed if necessary: If the calf doesn’t nurse, you can milk the cow and feed the colostrum via bottle or stomach tube. Tube feeding is safe and ensures the calf gets the full dose.
- Store extra colostrum: Freeze good-quality colostrum in 1-liter bags for emergencies. Thaw slowly in warm water (never microwave).
Signs of Colostrum Failure in Highland Calves
If a calf doesn’t get enough colostrum, it becomes susceptible to neonatal diarrhea (scours), pneumonia, and septicemia. Watch for these signs:
- Dullness and lethargy
- Dehydration (sunken eyes, dry nose)
- Diarrhea (watery, foul-smelling manure)
- Fever or low body temperature
- Swollen joints (navel ill)
Immediate veterinary treatment is critical if you see these signs. Prevention, however, is always better than cure.
Best Practices for Highland Cattle Farmers
- Vaccinate cows: Give a booster vaccine (e.g., ScourGuard) 4-6 weeks before calving to increase antibody levels in colostrum.
- Provide a clean calving area: Reduce environmental bacteria to lower infection risk.
- Monitor calf IgG levels: A blood test 24-48 hours after birth can measure passive transfer. A level above 1000 mg/dL is ideal.
Conclusion
Colostrum is the foundation of a healthy life for a newborn Highland calf. From boosting immunity to providing warmth, its role cannot be overstated. By understanding the importance of timing, quality, and quantity, you can give your Highland calves the best start possible. Remember: a healthy calf today means a thriving herd tomorrow.
