Abstract
THE domestic fowl has long been studied in laboratory as well as field biology. Selective breeding has led to the development and improvement of poultry strains particularly suited for egg production, as well as other strains which are rapid and efficient producers of meat. Total body growth of many of these strains has been studied in detail. Likewise, the effects of certain environmental factors on these growth patterns and on performance characteristics have also been studied (Deaton et al., 1969; Francis et al., 1968; McCartney et al., 1969; and Tindell et al., 1967a, b). Some of the important studies on organ-body weight relationships in poultry, in which a large number of organs were studied simultaneously, are those by Oakberg and Lucas (1949) and Oakberg (1951a, b) on 10 inbred lines of White Leghorn chickens, relative growth in bantams and leghorns (Lerner, 1941), the differential growth of organs and edible meat…
