Rutabaga And Sheep?

Question

You say that cruciferous veg are poisonous to sheep but I am wondering how. In the uk we call rutabaga, swede. Asa mangelworzel, a close relative of the swede – is expressly grown by the field and fed to them in winter can you expand please? I can understand that sheep might not like cabbage but when I feed them cauliflower leaves and swede, they love it. What cruciferous veg are good for sheep and what are poisonous? Many thanks. Kate.

Answer 1

Cruciferous vegetables like cabbage, kale, broccoli, and Brussels sprouts can be problematic for sheep if fed in large amounts. These veggies ferment quickly in the rumen, causing excess gas that can lead to dangerous bloat. They also contain goitrogens, which interfere with thyroid function, and glucosinolates, which can be toxic in high doses, causing gastrointestinal upset, anemia, or reduced growth. Additionally, some cruciferous veggies have high oxalate levels that can bind calcium, leading to deficiencies or kidney problems over time. If you want to feed them, keep portions small, introduce gradually, and mix them with other forage. Always monitor your sheep for signs of bloat or discomfort. For safer treats, opt for grass hay, alfalfa, or root veggies like carrots and beets in moderation.
