Dynamics of the microstructure and productive qualities of a mammary gland hybrid goat

The article presents the results of the microscopic examination and dynamics of the productive qualities of the mammary gland goats in age aspect. It is established, that the goat of the first lactation ratio of the parenchyma and proto is of 1.8:1 (with productivity for lactation l), the second-fourth of 2.7:1 (l), the fifth and older 2,5:1 (l), the comparative analysis of the biochemical properties of milk of these animals significant changes in the content of fat and protein is not revealed.
