No Substitute for Sunshine and Plenty of Green Fern There are probably no adequate substitutes for sunshine and succulent green feed for reducing the costs of feeding, keeping poultry in good health, promoting proper growth of bone and feather and developing good pullets for laying. Grasses and legumes in the early stages of growth contain relatively much more protein than in the later stages of growth. They are also rich in vitamins and will tend to balance and correct the deficiencies of proteins in the cereal grains fed to poultry. (See more in text.)
