Kovtunenko L. Рroductivity and metabolism at hens cross "Isa-Brown" аt use in a diet of amino acids and a poliminerol mix

The dissertation is devoted to studying of interrelation of acide-alkaline balance with efficiency on young growth of hens cross "Isa-Brown", and development of the new fodder admixture on the basis of the zeolite, being not only a source of mineral substances, vitamins, amino acids, but also the modifier of a fodder diet. In work are specified and determined effective dozes of application of a zeolitic flour in the pure state and in connection with the admixture aminoacid and two-carbonic sodium. By results of researches it is established, that most effective zeolite works in an organism as a source of mineral substances only in a combination to the admixture aminoacid and two-carbonic sodium. Introduction of carbonic-natrium ACA into the ration of egg - type chicks and hens regulates acid-alkaline balance in feeds making is reaction neutral or weak - alkaline that remlts in normalizing acid-alkaline balance, mineral, nitrogenous and energy exchange in poultry, accelerating the biological processes,increasing chicken growth rate and egg productivity of hens and also improving food and commercial qualities of eggs. On the basis of experimental researches the technology of preparation АCA, and also an effect doze (4 % from weight of a forage), it's usage in feeding chickens and hens сross "Isa-Brown", is offered. This technology and effect doze is proved to be true by zoo technical and biochemical researches. Branch- animal industrie.
