Question

‘Curled toe paralysis’ in chicks is a symptom caused due to the deficiency of
A. Phosphorous
B. Sulphur
C. Niacin
D. Riboflavin

Answer 1

Hint:
It has been shown that a diet low in riboflavin might result in two different nutritional deficiencies. One of these causes neuromalacia, a fast acute paralysis that results in curled toe paralysis in developing chicks, while the other, which develops more slowly, causes neuromalacia. Curled toe paralysis, which is caused by a deficiency in the vitamin riboflavin, is characterized by inward curling of the toes. Both inbreeding and improper incubation temperatures will raise the likelihood of crooked toes.
The ability of chicks fed diets that are only slightly low in riboflavin to recover on their own suggests that the requirement declines rapidly with age. In this state, birds may have brain tremors, paralysis of the wings or legs, or all three. Affected birds eventually starve to death, get crushed, or develop painful blisters.

Complete answer:
Deficiency in riboflavin is the cause of curled feet in chickens. However, the epithelium and the myelin sheaths of some of the major neurons are the primary targets of riboflavin deprivation. Growing chickens experience "curled-toe" paralysis due to changes in the sciatic nerves. LPS is not specifically treated. Treatment is required for subsequent infections, nutritional deficits, and inflammation. Injections of vitamins, corticosteroids, and antibiotics are examples of this. In the first 24 to 48 hours, fluid treatment, either via injection or crop tube, is typically necessary.
So, the symptom of curled toe paralysis is caused by riboflavin.

Option ‘D’ is correct

Note:
At two weeks of age, the tongue, oral cavity, and esophagus become clearly irritated, indicating a niacin deficit in chicks. Weight loss, decreased egg production, and a noticeably decreased hatchability can happen in the niacin-deficient hen. Niacin aids in the body's ability to transform different nutrients, including proteins, lipids, and carbs, into useful energy.
