Crowded cages: chromium and vitamin C for laying hens
360 Hy-Line hens were kept at 5 or 7 birds per cage. Crowding lowered egg production, egg mass and feed intake. Chromium-methionine increased egg production and egg mass, and worked together with vitamin C to improve production and feed conversion.
Practical takeawayWhen cage density is high, chromium-methionine (with vitamin C) helps protect egg output.
