The present paper describes chondrodystrophy (previously called perosis) in three poultry units producing labeled chickens. An unilateral deviation of a hind leg along with a tumefaction of the tarsal joint appeared in 4 days to 4 weeks old birds; 5 to 50 / of the animals being affected. The growth rate was reduced and cachexia was also observed. There were also breast blisters. Chemical analyses were carried out on the poultry feed in two of the units. The manganese content was below the requirements at about 35 mg/kg; in one unit, the ionic balance (Na + K - Cl) was insufficient along with a too narrow Ca/P. The insufficient supply in manganese was corrected by the addition of manganese sulphate in water at a rate of 120 g/1.000 liter of water. Manganese sulphate was also added in the feedstuff at a rate of 120 g/t.
