Essential cofactor for pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase in energy metabolism. Critical for neurological function.
Deficiency causes polioencephalomalacia in ruminants and neurological signs in cats (fish-based diets, cooked meat diets). IV thiamine can cause anaphylaxis — give IM or slow IV. Very safe orally.
Species-specific contraindications and adverse-reaction reports for chickens may differ from canine / feline reference data — consult the primary citations listed with each rule.
