It is very difficult and very expensive to supply all nutrients at the
exact needs – rather we have to over supply some nutrients in
practical situations, in an attempt to meet the limiting nutrients. In
poultry diets these limiting nutrients are usually energy and some of
the essential amino acids, such as methionine and lysine.
While formulating feeds, we are guided by the following factors:
Nutrient requirement for the bird.
Availability of the raw materials.
Price of the raw materials
Presence of anti-nutritive factor.
The following nutrients are required by the bird for
proper bone development and production:
1. Energy rich feeds that include maize, millet, Sorghum, sugar,
maize bran, pollard, wheat bran, pollard, maize germ and
tubers.
2. Protein rich feeds like blood meal, fish meal, meat and bone
meal, cotton seed, soya meal, sunflower meal, peanut meal,
beans, peas, oil cakes, fish, maggots, termites, worms, insects.
3. Mineral rich feeds like bone meal and burned egg shells.
4. Vitamins: from green grass, vegetables, fresh cow dung (scavenging
birds).
5. Non nutrient substances: Grits, toxin binders etc.
A. Poultry - Any of the domesticated and commercialized types of
birds used for production of eggs and (or) meat for human food
e.g., Chickens, turkeys, pigeons, peafowl, ducks, geese, upland
game birds (quail, pheasant, partridges, etc.) and ratites
(ostriches, emu, etc.).
B. Chickens, turkeys and laying hens have been commercially
produced in the Confinement system for more than 70 years and in the free range system from time immemorial.
