Mineral status of the organism of copps of different types of high nervous activity
Abstract
New scientific data on the degree and nature of the effect of force, balance and mobility of cortical processes on the mineral status in the body of cows are given. The experiment was conducted on cows of Ukrainian black-and-white milk breed of second-third lactation of different types of higher nervous activity. Investigations of conditioned-reflex activity were conducted using the modified method of conditional-food reflexes G.V. Parshutina and T.V. Hippolyte. The material for research was blood samples of animals, in which the content of individual macro- and trace elements was determined. It is established that in an animal of a strong, balanced, mobile type of higher nervous activity an optimum content of macroelements in the blood is established. Thus, the content of sodium was 119.3 ± 1.1 mmol/dm3, Kcal – 5.62 ± 0.39 mmol/dm3, phosphorus – 8.38 ± 0.11 mmol/dm3, calcium – 2.22 ± 0.09 mmol/dm3 and magnesium – 0.84 ± 0.02 mmol/dm3. In cows of a strong, balanced inert type of higher nervous activity, the content of phosphorus in the blood is lower by 9.3% (P < 0.01), in animals of a strong unbalanced type, the content of phosphorus and magnesium is less by 7.4–9.6% (P < 0.01) and in cows of weak type the content of Potassium, Phosphorus and Magnesium is lower by 13.3–29.2% (P < 0.001) from the indicator of animals of a strong, balanced, mobile type of higher nervous activity. The microelement status of the cows of a strong, balanced, mobile type of higher nervous activity is characterized by the following their content in the blood: Ferrum – 17.8 ± 0.6 μmol/dm3 Zinc – 20.67 ± 0.95 μmol/dm3 Manganese – 0.84 ± 0.02 μmol/dm3 and Kuprum – 13.28 ± 0.29 μmol/dm3. In blood of strong, balanced, inert and strong unbalanced type, the content of zinc in the blood is lower by 17.1–18.5% (P < 0.001), in animals of weak type the content of Ferum, Zinc, Mangan and Kuprum is less than 8.0–24.6% (P < 0.05–0.001) in accordance with the indices of strong, balanced, mobile type of higher nervous activity.
