Zlamanuyk L. Use of a fodders and efficiency Japanese quails at different levels of calcium and phosphorus in mixed fodders

Object - quails of the Japanese breed of an egg direction of efficiency for a different level of a calcium - phosphoric feed. The purpose - to establish optimum levels of calcium and phosphorus in mixed fodders of female quails of the Japanese breed for maintenance more efficiency uses of a forage and quality of received production. Methods - zootechnical, biochemical, biophysical and statistical. Novelty - For the first time is carried out a comparative estimation of productive qualities of female quails of an egg direction of efficiency on a level of a calcium- phosphoric feed. The new data be relative digestion the basic nutrients, an exchange of nitrogen and mineral elements in an organism of female quails are received. The data on influence of different levels calcium and a phosphoric feed quails on mineral structure of a skeleton are expanded. It is established, that increase of levels of calcium and phosphorus in a diet of female quails assists increase of contents of calcium and dry substance in a skeleton. It is established, that uses in feedings female quails of mixed fodder with contents of 3,0 % of calcium and 0,8 % of phosphorus are provided most with a high level of efficiency, digestion nutrients and improves mastering nitrogen and mineral substances in an organism of birds. Results of researches - are used in practice, educational process and research work. Branch - animal industries.
