DEFICIENCY – CURLED TOE PARALYSIS / CLUBBED DOWN CONDITION

• Poor appetite, retarded growth, vomiting, skin eruptions and eye abnormalities.
• In chicks riboflavin deficiency causes curled toe paralysis caused due to peripheral nerve degeneration, in which the chicks walk on their hocks with the toes curled inwards.
• In breeding hens deficiency causes decreased hatchability. Embryonic abnormalities occur including the clubbed down condition in which the down feather continues to grow within the follicle leading to curled feather.
