DEFICIENCY - PEROSIS OR 'SLIPPED TENDON'

• Manganese is an important element in the diet of young chicks, a deficiency leading to perosis or 'slipped tendon', a malformation of the leg bones.
• There is enlargement of the hock joint, thickening and shortening of the tibia which causes Achilles tendon to slip from its condyle causing the leg of the bird to be pulled sideward and backward.
