Riboflavin ( Vitamin B2):

A part of enzyme regulatory mechanism so plays a vital role in metabolism. The deficiency causes diarrhea and “curled toe paralysis” in birds between the first and second week of age.

In adult birds, decreased egg production increased embryonic mortality, and dead in shell chicks, with dwarfing and clubbing down feathers are seen.

Embryo mortality reaches a peak between 18 to 20 days of incubation. Grasses and brewer’s yeast are rich sources of this vitamin.

Thiamine (Vitamin B1):

It is necessary for proper carbohydrate metabolism. The deficient birds show anorexia, loss of weight, ruffled feathers, dropping of wings, and paralysis of muscles.

The birds sit on flexed legs and draw back the head in a ‘star-gazing position. It is found in abundance in rice polish, wheat bran, and cereal grains.

Pyridoxine (Vitamin B6):

It is necessary for the proper metabolism of amino acids. Due to deficiency, spasmodic convulsions and jerky movements are seen in sick birds. The bird should be fed cereal grains, yeast, and alfalfa meal.

Cyanocobalamin (Vitamin B12):

It is involved with nucleic acid synthesis, carbohydrate and fat metabolism, and methyl synthesis. This is found in all foods of animal origin.

Its deficiency shows slowed growth, poor feed utilization, and reduced hatchability. Embryonic mortality reaches a peak on the 17th day of incubation.

Myotrophy of legs and hemorrhages in the allantois of the embryo may be seen. Fish meal, milk products, and animal proteins are sources of vitamin B12.
