In a previous publication (Edwards & Duthie, 1971) the metabolizable energy values for broiler chicks of 11 samples of winter-sown Throws M. S. field beans from the 1968 harvest were reported. The samples had been grown at different locations in England which represented a variety of soil types. The mean ‘classical’ and nitrogen-corrected metabolizable energy values were 2–40 ± 0–09 kcal/g and 2–26 ±0-11 kcal/g respectively, with as much as 27 % difference between the highest and lowest individual values.
