Digestibility trials with poultry. IX. The digestibility and metabolizable energy of sunflower seeds

1. Field tests indicate that sunflower seeds are suitable as a wartime substitute for cereal grains for fowls, and that eggs produced on rations containing these seeds are excellent in both flavour and quality. 2. Digestibility trials indicate that sunflower seeds are a good source of protein and energy. 3. On an energy basis, metabolizable energy determinations indicate that sunflower seeds yield more energy than cereal grains on a weight-for-weight basis, with the exception of yellow maize. 4. Under commercial conditions of management, sunflower seeds appear to be quite palatable to poultry, but not under conditions of individual cage feeding.
