Abstract :
    Poultry selected for rapid growth are susceptible to lameness, and it can be a significant source of mortality in heavy birds. Genetic selection has been successful in providing annual improvements in meat poultry productivity; however, some support systems, such as the cardiovascular and skeletal systems, have not kept up with the increase in body mass, making birds increasingly susceptible to compromise or failure of these systems. Metabolic diseases are associated with a rapid early growth rate in poultry, especially in broilers, and their incidence can be decreased by slowing early growth. Leg problems seen in the absence of infectious agents are often the result of fast early growth and thus can be related to metabolic diseases. At hatch, the broiler skeleton is poorly mineralized; growth and mineralization occur most rapidly in the first 2 wk of life. Except for Ca, the embryo has limited access to minerals. Most minerals in the egg cannot be influenced by maternal diet, but embryo mineral uptake can be improved by dietary mineral source selection. At hatch, the broiler skeleton is poorly mineralized; growth and mineralization occurs most rapidly in the first 2 wk of life.
