Curled toe paralysis of poultry is caused due to deficiency of –

✅Explanation: Riboflavin deficiency is the primary cause of curled toe paralysis in poultry. This condition affects the nervous system, leading to the characteristic curling of toes.

📌 Other Options Explanations:
-Niacin (B3): Deficiency leads to pellagra in humans.
-Thiamine (B1): Deficiency causes beriberi, characterized by neurological and cardiovascular symptoms.
-Pyridoxine (B6): Deficiency results in various neurological and skin issues.

🔑Key Points:
-Curled toe paralysis is caused by riboflavin (vitamin B2) deficiency in young chicks.
-It is one of the most characteristic signs associated with vitamin deficiency, resulting in the curling of the chick's toes.
-Occurs in chicks fed outdated or improperly stored starter feed, or who are bred from parents with riboflavin- deficient diet.
-Chicks that are fed riboflavin- deficient diet will begin to show signs at about 8 to 14 days following hatch.
-Affected chicks soon become reluctant to move, followed by intermittent flexing and inward curling of toes.

• ​🛑Additional Information::

•    Prevention:
-Ensure any adult chickens intended for breeding are receiving enough riboflavin in their diet (10 – 16 mg/kg).
-Feed newly hatched chicks a fresh bag of starter chicken feed (not feed that has been stored for longer than 2 months), with additional riboflavin food sources during the two weeks of life.
-During warm weather, provide supplemental sources of riboflavin.
-Store feed in a sealed plastic container located away from direct sunlight.
