Pine needles may seem harmless, but for pregnant cows, they can be deadly.
When consumed in large amounts, especially during the last trimester of pregnancy, pine needles can cause late-term abortions in cattle. This condition is often referred to as pine needle abortion, and it is linked to a chemical compound called isocupressic acid, found in various pine species (like Ponderosa pine).
⚠️ Symptoms to Watch For:
- Premature labor or abortion
- Swelling of the udder without calving
- Isolation or discomfort
- Lethargy and loss of appetite
🌲 How It Happens:
Cows may browse on fallen pine needles or break branches to eat them—especially when feed is scarce during the cold season. Drought and snow cover make this more likely.
🛡️ Prevention Tips:
- Avoid letting pregnant cows graze in pine-dense areas, especially in the last 3 months of pregnancy.
- Provide enough forage or hay to minimize browsing behavior.
- Fence off areas with pine trees if needed.
- Monitor for signs of premature labor and isolate affected animals.
🩺 If You Suspect a Problem:
The best thing to do is contact your veterinarian immediately. While there’s no antidote for the toxins, your vet can help manage the situation and prevent further loss.
