Abstract: This experiment was carried out to effect of different levels of calcium, phosphorus and vitamin D3 on the calcium, phosphorus and magnesium of plasma, hatchability and performance from Ross 308 broiler breeders with 20 weeks af age at begining of the experiment. A completely randomized experimental design was applied in 3x2 factorial arrangement with 3 levels of calcium 3.122, 85, 2.56 and 3 levels of phosphorous 0.41, 0.37, 0.33 and 2 levels of vitamin D3 (3300, 3000 IU) with 4 replicates of 10 birds plus one cockerel in each pen. At end of experiment different parameters such as calcium, phosphorus and magnesium of plasma percentage, egg shell percentage, egg weight, calcium and phosphorus of tibia, hatchability, production and feed conversion ratio measured. After statistical analysis, it became clear that the treatments effect on all parameters except, production, hatchability and FCR cannot have a significant affect (p<0.05). It was concluded that the positive function of vitamin D3 Iin this field.
