Goat Browse Reference
Goats are browsers, not grazers — they prefer leaves, twigs, and shrubs to grass. Plus toxic plant warnings and using goats for invasive control.
Why goats are browsers, not grazers
A goat's natural diet is ~60-70% browse (leaves, twigs, shrubs), 20-30% forbs (broadleaf weeds), and only 10-20% grass. Their physiology reflects this:
- Tannin tolerance: Goats process tannins efficiently — many woody browse plants that would harm cattle / horses are fine for goats
- Selective feeders: Goats taste-test and reject parts of plants; cattle eat what's in front of them
- Climbing + reaching: Goats stand on hind legs, climb low branches; access browse other livestock can't
- Liver detoxification: Goats can metabolize many plant alkaloids, but NOT all — toxics still kill goats
Goats for invasive plant control
Goats are commercial ecological tools for controlling brushy invasives. They eat what cattle won't and tolerate steep slopes mechanical equipment can't access:
| Invasive plant | Goat effectiveness |
|---|---|
| Multiflora rose (Rosa multiflora) | ★★★★★ Highly preferred; goats kill bushes in 2-3 years of pressure |
| Kudzu | ★★★★★ Top control; goats devour kudzu vines repeatedly |
| Honeysuckle (Lonicera spp.) | ★★★★ Effective; eats foliage + bark |
| Privet (Ligustrum) | ★★★★ Heavy browser preference |
| Russian olive (Elaeagnus angustifolia) | ★★★★ Effective |
| Buckthorn (Rhamnus cathartica) | ★★★ Eats but tolerates poorly; best for foliage only |
| Garlic mustard (Alliaria petiolata) | ★★★ Eaten readily |
| Poison ivy | ★★★★★ Goats love it; immune to urushiol; commercial service exists |
| Blackberry / brambles | ★★★★ Top preference; can clear acres |
| Greenbriar (Smilax) | ★★★ Eats young growth |
| Tree of Heaven (Ailanthus) | ★★ Eaten when young; mature trees ignored |
| Japanese knotweed | ★ Ineffective — goats don't like it |
| Yellow star thistle | ★★★★ Effective at flower stage |
| Leafy spurge | ★★★★★ Goats are go-to control; cattle won't eat it |
The most lethal toxic plants — memorize these
| Plant | Lethal dose | Notes |
|---|---|---|
| Mountain laurel, rhododendron, azalea | ~1-2 oz fresh leaves can kill an adult goat | Most common goat poisoning in eastern US; ALL parts toxic |
| Yew (Taxus) | ~0.1% body weight (very small) | Cardiotoxic; few minutes to death; common in landscaping |
| Oleander | One leaf can kill | Common ornamental in warm regions |
| Wilted cherry leaves (Prunus) | 2-4 oz wilted leaves dangerous | Fresh + fully dry usually fine; WILTING produces cyanide |
| Black walnut shavings/bedding | Large amounts | Fresh shavings; aged usually fine |
| Hemlock (Conium) | ~0.5% body weight | Roadside weed; classic Socrates poison; ALL parts toxic |
| Death camas (Zigadenus) | ~1% body weight | Western US ranges; spring growth most dangerous |
| Wild cherry sprouts (after wind/storm) | Variable | Same wilting cyanide concern; check pasture after storms |
| Larkspur (Delphinium) | ~1-2% body weight | Western mountain pastures; spring + early summer |
| Locoweed (Astragalus, Oxytropis) | Cumulative; chronic | Western ranges; addictive — once started, hard to break |
Common garden plants that are toxic
- Rhubarb leaves — high oxalic acid; kidney damage
- Tomato + potato leaves/vines — solanine; goats often refuse but young animals may try
- Avocado (any part) — persin toxic to goats
- Onions, garlic, leeks (large amounts) — hemolytic anemia
- Foxglove (Digitalis) — heart toxin
- Lily of the valley — cardiotoxic
- Daffodils, tulips, hyacinth bulbs — toxic alkaloids
- Castor bean (Ricinus) — ricin; lethal
- Lantana — liver toxin; common landscaping in warm zones
Toxic-vs-tolerated table — common questions
| Plant | Status | Notes |
|---|---|---|
| Acorns / oak leaves | OK in moderation | Tannic; large quantities cause kidney damage but seasonal feeding fine |
| Pine needles (most species) | OK | Some pine boughs OK; ponderosa pine causes abortion in late pregnancy |
| Cedar (Eastern red cedar) | OK | Goats love it; kills cedar invading pastures |
| Maple leaves (most) | OK | Red maple wilted leaves dangerous to horses but generally fine for goats |
| Holly | OK in moderation | Eaten readily; large amounts cause GI upset |
| Ivy (English/Hedera) | Mild toxicity | Goats eat without issue; small amounts only of concern |
| Apple/pear leaves | OK | Same wilting cyanide as cherry but much less; routine browse |
| Dandelion, plantain, thistle | Loved | Top forage |
| Burdock (Arctium) | OK | Eaten readily; medicinal value |
| Comfrey | OK in moderation | Long-term large amounts can cause liver issues |
