Abstract
Mineral and electrolyte metabolism are of particular importance in dairy cows due to the peculiarities of their physiology, which becomes more relevant in conditions of high productivity. Milk production directly affects the state of mineral metabolism in cows, and without a balanced diet that satisfies all the body’s needs, there is a risk of various pathologies and a violation of the quality of the final product (milk). During the lactation period, dairy cows are especially susceptible to deficiencies in the most important macroelements: calcium, phosphorus and basic electrolytes (potassium, sodium, chlorine), and given the tendency to increase productivity, this problem does not lose its relevance. It follows that the development of high-quality feed additives is one of the priorities of livestock farming. Also an important component of this issue is the development of safe additives based on natural components (for example, algae). Feed additives based on fucus algae have a number of useful properties, especially in livestock farming conditions, which can have a beneficial effect on the organisms of farm animals, dairy cows, in particular. In addition to the high content of various macro- and microelements, algae are an important source of fiber and other biologically active substances that can correct deficiencies in diets and have a positive effect on the digestibility of nutrients.
