The common ingredients are whole maize, maize bran, cotton seed cake, soya beans, sunflower and fishmeal (omena). In addition, farmers need to add several feed additives (micronutrients, minerals and vitamins) to ensure their birds have a balanced feed that meets their daily nutrient requirements. Ingredients are cheaply available, especially after the harvesting season. Depending on the cost of ingredients, farmers who make their own feeds at home save between 30 to 50% for every 70kg bag of chicken feed, depending on the source of their raw materials.
