Source

• Natural feeds
• Rice bran is a very good source of manganese
• Present in all tissues esp. liver

Functions

• Cofactor for many enzymes (Kreb’s cycle)
• Mn has close working relationship with Mg
• It affects bone & egg shell formation

Deficiency

• Birds are more susceptible for Mn deficiency

Chondrodystrophy

• Young growing birds → Growth retarded

Laying birds

• Egg shell – thin – porous, soft
• ↓ egg production, ↓ hatchability, Dead embroyes

Adult birds - perosis / slipped tendon

• Normal bone growth affected
• Mn essential for synthesis of cartilage matrix
• Shortening of long bones
• Epiphyseal cartilage fails to ossify
• Slipping of gastrocnemius tendon
