Bones of an axial atomy, the content of calcium and phosphoms in a bony tissue of chickens-broilers of cross-country ROSS-308 in the separate terms of an ontogenesis, 5 age groups were investigated. The terms most healthy growth, dynamics of the content of calcium and phosphorus in a bony tissue are positioned It is possible to make the conclusion that development of bones of an axial atomy of chickens-broilers of cross-country ROSS-308 with the 1st to the age 40-daily allowance goes intensively, but non-uniformly. With 20 for 30 days recession of intensity of development both an axial skeleton, and a body weight is observed. The calcium content at daily age is more than phosphorus content in 7,5 times. The phosphorus content on the average in 3,7 times is more than calcium in 40-daily allowances age. With 20 to 40 daily age there is a decrease in the content of calcium, but the content of phosphorus which increases and becomes equal to the content in daily age. It is necessary for considering by working out of new technologies of growing of chickens-broilers for the purpose of correction of diets of feeding that will allow to reduce even more terms of fattening and to lower the economic costs
