Charkin Volodymyr was PhD in Biology, Senior researcher, Head of the Laboratory of Cattle Nutrition that focuses on researching the physiology of animal lactation, studying the influence of Iodium, Chromium, Selenium, Cobalt on metabolic processes, productivity and composition of milk; development of elements of national protein feeding system of high productive cows that correspond to modern protein standardizing criteria. Lactation is a complex process of creation, storing and producing milk in animal’s mammal gland. Nervous system and hormones of endocrine glands with the help of brain cortex and hypothalamus, where lactation center is located, regulate the process of mild production. Hypothalamus produces releasing factors – somatoliberin and prolactoliberin that stimulate the production of hormones somatotropin and prolactin in hypothesis. These hormones directly take part in the production of milk. The role of other endocrine glands is that they contribute to promotion of the synthesis of milk precursors and increase of their amount in blood.
