Which of the following ingredients is required for the formation of egg-shell in poultry?

Bone meal is the ingredient that is required for the formation of eggshell in poultry. Eggshells are primarily made of calcium carbonate, which is a mineral that is essential for the formation of strong and healthy eggshells. Bone meal is a source of calcium that is easily absorbed by the body, making it an important ingredient in poultry feed. Poultry require a regular supply of calcium to produce strong eggshells. If they do not get enough calcium in their diet, they may lay eggs with thin or weak shells, or even without shells at all. This can lead to problems such as broken or cracked eggs, reduced hatchability of eggs, and increased risk of infection. In summary, bone meal is an important ingredient in poultry feed because it provides the calcium that is necessary for the formation of strong and healthy eggshells.
