简介
Poultry production has an important in economic, social and cultural benefit and as role a nutrition supply in development country (Desalew Tadesse et al., 2013). Village chickens are the most common type of livestock in many rural areas (M Chibinga, 2016) and developing countries as a food source (Muhiye, 2007). Ayam Kampung MARDI (AKM) introduced at the Malaysia Agriculture, Horticulture and Agro-Tourism Exhibition (MAHA) 2012. The AKM slower growth rate in growth and production, poor laying ability and smaller egg size as compared to commercial breeds. It was to produce uniform in terms of body size, physical characteristics, growth and better laying chickens compared to the original breed.
Calcium (Ca) and Phosphorus (P) is one of the key nutrients required for bone, egg quality, growth performance, layers and breeder. The Ca well over 90% found in the bone where it combines with P as second most important mineral element in bone, to from calcium phosphate crystals (Gordon & Roland, 1996) In feed nutrition other important element for body system including Na, Mg, Fe and Fi. In addition, phosphorus as essential component of almost all metabolic processes (McDonald et al., nd) The P content less than from Ca between 80 to 85% of the total phosphorus found in the bones function. Phosphates are used for metabolism and energy storage in formation of sugar phosphates and adenosine di-and tri-phosphates. Furthermore, P form part of a protein that contains phosphorus, nucleic acids and phospholipids (Driver, John Patrick, 1994).
