CHALK STERN
Chalk fodder natural ground contains 37% calcium, 0.18% phosphorus, 0.5% potassium, 0.3% sodium and not more than 5% silicon and other elements. It is a homogeneous white powder, odorless, practically insoluble in water.
Feed chalk is one of the main sources of calcium. Calcium stimulates the function of the cardiovascular system, is one of the blood coagulation factors, ensures the constancy of osmotic pressure. It participates in the conduction of a nerve impulse, in the initiation of muscle contraction due to the formation of an actin-myosin complex, and activates, together with insulin, the penetration of glucose into cells. Calcium forms bone tissue, maintains muscle tone, prevents premature development of osteoporosis and osteomalacia, promotes the proper formation of the musculoskeletal system, which is especially important for young animals and birds. Calcium is part of various enzyme systems that catalyze biochemical reactions in the body, in addition, it increases the nonspecific resistance of the animal. Calcium ions are involved in the transmission of nerve impulses, in the contraction of skeletal and smooth muscles. The intercellular bone substance is rich in calcium salts, together with proteins (mainly collagen - ossein) ensures the hardness and elasticity of the bone. Calcium has a beneficial effect on the metabolism of iron in the body of animals and birds, removes toxins.
When using the additive in productive animals, the average daily gain in muscle mass increases, the quality and yield of meat products, milk yield improves, egg production increases in birds, as well as the safety of eggs and the dietary properties of the finished product. The process of absorption and resorption of calcium in the body is closely related to the intake of phosphorus and vitamin D, with the optimal ratio of these elements, their absorption is maximum. Chalk consumption rates are strictly focused on the need of the body of animals and birds for calcium, depending on the physiological state of the body, the presence of pathological processes, as well as age. With prolonged unbalanced nutrition in terms of micro- and macroelements, animals and birds develop irreversible pathological processes, they are especially pronounced with a lack of calcium, vitamin D and iron. On the part of the musculoskeletal system - restructuring of the skeleton, demineralization, dystrophy, softening and deformation of the bone, rickets develops (rachitic beads on the ribs). Muscle tone also decreases, the change of teeth is delayed in young animals, hypochromic anemia develops, atony of the gastrointestinal tract. Calcium deficiency especially affects the overall development and growth of young farm animals and poultry. In laying hens, egg production decreases, egg shells become thinner. Dystrophic processes also develop in the muscles, resulting in a sharp drop in the quality and yield of meat products. When administered orally, the mineral components of the supplement are rapidly absorbed and excreted from the body mainly in the urine.
In order to enrich and increase feed conversion. To improve the productivity and quality of livestock products.
