Dietary Calcium Supplement for Avian Species

Origin and Composition

Derived from the internal shell of a cephalopod mollusk. Primarily composed of calcium carbonate (CaCO3), accounting for roughly 85% of its total mass. Also contains trace minerals such as magnesium, iron, zinc, and manganese, which contribute to overall nutritional value.

Primary Function in Avian Nutrition

Serves as a readily available and highly bioavailable source of calcium. Calcium is essential for numerous physiological processes in birds, including:

  • Bone Formation and Maintenance: Crucial for skeletal development and maintaining bone density, particularly important for growing birds and breeding females.
  • Eggshell Formation: Hens require significant calcium reserves to produce strong and healthy eggshells. Deficiency can result in thin, brittle, or soft-shelled eggs.
  • Muscle Function: Calcium plays a vital role in muscle contraction, including heart muscle function.
  • Nerve Function: Involved in nerve impulse transmission and maintaining proper nervous system function.
  • Blood Clotting: Necessary for the blood coagulation process.

Forms and Presentation

Typically available in several forms:

  • Whole, Natural: The unprocessed shell, often with the outer layer partially or fully removed. Birds can peck and break off small pieces.
  • Powdered: Can be added to food or used as a supplement in prepared diets.
  • Blocks and Treats: Integrated into formulated blocks or treats, often combined with other nutrients and flavors.

Benefits of Usage

  • Supports Bone Health: Provides structural support for bones, reducing the risk of fractures and deformities.
  • Enhances Eggshell Quality: Improves eggshell strength and reduces the incidence of egg-binding in breeding females.
  • Promotes Overall Health: Contributes to overall well-being by supporting essential bodily functions.
  • Beak Maintenance: Pecking at it helps to keep beaks trimmed and healthy.

Considerations for Usage

  • Availability: Should be accessible at all times, particularly for breeding birds.
  • Hygiene: Keep clean and dry to prevent bacterial or fungal growth. Replace regularly.
  • Supplementation: While a good source of calcium, it may not provide all necessary nutrients. Ensure a balanced diet is offered.
  • Over-Supplementation: Excessive calcium intake can lead to health problems; use in moderation as part of a balanced diet.
