Most Toxic Common Plants for Goats


1. Alfalfa

  • Goats can eat alfalfa in moderate quantities. But when they overindulge (often in the spring), they consume an excess of calcium, and it causes issues with their digestive system as their diet is no longer balanced.

  • It is important goats eat alfalfa in moderation or it can lead to a life threatening condition called bloat.

2. Buttercups

  • Most goats will not eat buttercups as they recognize them as toxic. When consumed, this flower disrupts the rumen and can cause diarrhea.

3. Cherry

  • Like many fruit trees, cherry leaves and fruit are toxic to goats. Other trees that can be toxic to goats include apricots, crabapples, nectarines, prunes, peaches, and even plums.

4. Clover

  • Goats can eat clover in moderate quantities. But when they overindulge, commonly in the spring after a long winter. Goats consume an excess of calcium, and it causes issues with their digestive system as their diet is no longer balanced similar to alfalfa.

  • It is important goats eat clover in moderation or it can lead to a life threatening condition called bloat.

5. Poppy

  • Due to the alkaloids in this plant, it is toxic to goats. Unfortunately, goats tend to be very fond of this poisonous plant, so it is especially important to ensure it is out of reach.

6. Elderberry

  • Throughout the entire plant elderberries contain alkaloid and cyanogenic properties. Making this a highly toxic plant for your herd.

7. Ground Ivy

  • Depending on the type of ivy, this can be toxic for your goats. The rule of thumb is that ground ivy and landscaping plants are generally toxic and best to avoid keeping your goats safe and healthy.

8. Milkweed

  • Known for causing digestive issues in ruminants (goats, cattle, sheep, and horses) this plant should be avoided.

9. Nightshade

10. Oaks

  • Typically poisoning from browsing near an oak tree has minimal side effects. But with continuous ingestion side effects can occur.

  • Most common poisoning in goats as they often graze on this plant in the spring when other plants are not green yet. This plant disrupts the digestive system and causes vomiting and muscle issues (including the heart).

12. St. John's Wort
