- Abstract
Nutrition is a crucial factor in animal production. Feeding animals with a well-balanced diet is beneficial economically and promotes animal welfare. Mineral supplements are the third most costly component in animal feed. Phosphorus (P) is one of the key minerals responsible for skeletal development, energy metabolism, cell signaling and is a constituent of nucleotides. An animal's P requirement varies with species, production trait, age and management practices. Dietary P should meet the growth, maintenance, and production requirements of animals. Deficiency in dietary P causes severe impacts on skeletal development and growth in young animals and long-term deficiencies can impact both animal welfare and production parameters. Overfeeding of P can lead to nutritional disorders related to Ca metabolism. Therefore, maintaining the balance between Ca and P in the diet is crucial in feeding. Excess P is not retained in the body and excreted with faecal matter. Through the homeostasis process, animals are able to balance the mineral composition in their bodies. The primary P source in the diet comes as organic P from plants and inorganic P from supplements. The bioavailability of the P varies within animals according to physiological and functional variabilities. Understanding the physiology as well as functional and production variabilities in animals is beneficial in managing the economic and environmental aspects of animal husbandry.
