Acorn Poisoning

Acorns, young buds, twigs and leaves from oak trees (Quercus spp) are toxic to goats if ingested in sufficient quantities. They contain polyphenolic complexes known as hydrolyzable tannins, specifically gallotannins, which are toxic to goats. When large amounts of tannins are present in the goat's system, they negatively interact with the levels of protein in their body, causing damage to their gastrointestinal system, renal functioning and less frequently, liver.

The concentration of hydrolyzable tannins present varies based on oak species, season, and stage of growth; they are highest in immature leaves (which grow in the spring) and acorns that have recently fallen from trees (occurs in the fall). Eating small amounts of leaves or acorns is generally harmless. However, when it can become a problem is when goats develop an acquired taste, and actively seek them out in pastures, which can occur. Consumption of small quantities of acorns may only result in mild clinical signs, in which recovery is possible. However, when large quantities of acorns are ingested, signs are much more severe, often causing typhylocolitis leading to diarrhea, colic and acute renal tubular nephrosis.



Treatment Options

Supportive care - aggressive fluid therapy, limited stress, and laxative treatment until the acorns pass through the goat's system.
