Riboflavin Deficiency is a chicken health condition. Riboflavin deficiency causes neurological signs and stunting. However, it is easily prevented through proper feed and rapidly improves with dietary correction. This guide covers what to watch for, causes, treatment, and prevention strategies.
What It Looks Like
Watch for these signs:
Feet and toes: Toes curl inward permanently; bird cannot extend toes normally
Nervous system and legs: Bird staggers, walks abnormally, or has difficulty standing
Overall development: Chicks grow slowly and remain smaller than healthy peers
Feathers: Feathers appear thin, rough, or unkempt
Digestive system: Loose, watery droppings present
Face and skin: Skin around eyes becomes red, scaly, or inflamed
Likely Causes
- Inadequate dietary riboflavin (vitamin B2) in feed
- Poor quality feedstuffs low in riboflavin
- Lack of vitamin/mineral premix in home-formulated feed
- Riboflavin is essential for energy metabolism and nervous system function
- Young growing birds have high requirements
About This Condition
Body System Affected: Nervous system and connective tissue
Severity: moderate
Contagious: No, not contagious
Affected Age Groups: chicks, pullets
What to Do
Switch immediately to commercial poultry feed meeting NRC riboflavin requirements (5-the appropriate amount/kg for growing birds). If formulating your own feed, include a complete vitamin/mineral premix. Affected birds recover quickly from nutritional deficiency once diet is corrected. Neurological signs (curled toes) may persist if severe.
When to See a Vet
See a vet if your chicks show curled toes, neurological signs, or poor growth. Your vet can evaluate the feed and recommend dietary adjustments.
Prevention
Use high-quality commercial poultry feed meeting NRC standards. If mixing your own feed, include a complete vitamin/mineral premix. Avoid poor-quality feedstuffs. Ensure feed is fresh (B vitamins degrade with age and storage).
Frequently Asked Questions
Q1: Is curled-toe paralysis permanent?
If caught early and diet is corrected, signs may resolve. If deficiency persists, permanent neurological damage and toe deformity occur.
Q2: What foods are high in riboflavin?
Riboflavin is found in whole grains, yeast, fish meal, and legumes. Commercial vitamin/mineral premixes provide concentrated riboflavin.
Q3: How quickly does riboflavin deficiency develop?
Clinical signs appear after 2-3 weeks of deficient diet in young birds. Severe deficiency develops quickly; prevention is easier than treatment.
