Vitamin B6 Deficiency

Pyridoxine Deficiency

Vitamin B6, also called pyridoxine, helps the duck's body make several neurotransmitter chemicals that carry signals from one nerve cell to another. It is required by several enzymes, including those involved in the breakdown of amino acids.

Clinical Presentation

Ducklings fed a vitamin B6-deficient diet have little appetite poor growth, chondrodystrophy, and characteristic nervous behavior. Ducklings may show jerky, nervous movements of the legs, run aimlessly about, flapping their wings, or squating with their wings slightly spread out and their heads resting on the ground. Chronic borderline B6 deficiency produces perosis; usually one leg is severely crippled, and one or both of the middle toes may be bent inward at the first joint.
