Leanness in domestic birds : genetic, metabolic, and hormonal aspects /
Leanness in Domestic Birds: Genetic, Metabolic, and Hormonal Aspects is a proceeding of a symposium held in Tours, France, from 4 to 6 August 1987. Said symposium was concerned with genetic and metabolic factors associated with leanness of poultry and accounts of research in these areas.
