Mineral substances: Regulators electrochemical rection of the contens rumen in high yielding dairy cows

Abstract

The contemporary informations about importance and possibilities for maintaining the optimal electrochemical reaction in the organism in high yielding dairy cows were given in this paper. The most important functions were shown for cations (Ca2+, Mg2+, K+, Na+) and anions (P3-, S2-, Cl-), and variability in their content in feedstuffs. The equations for calculation the cation/anion balance (DCAD)in cow diets were given and practical examples of their use. It is concluded that the problem of optimal electrochemical reaction in the body of high yielding dairy cows can be solved, although to a limited extent, using feedstuffs with favorable cation/anion ratio. When it is not possible to solve the problem with feedstuff choice, the effective way is to use chemical compounds in the form of cation and anion salts, and preparations based on natural minerals (zeolite, bentonite). The results of experiments where some DCAD-regulating mixtures were used and their effects on prevention of hypocalcaemia, which causes puerperal paresis, and the main productive and reproductive parameters in cows.

U radu se razmatraju novija saznanja o održavanju optimalne elektrohemijske reakcije u organizmu visokomlečnih krava. Ukazano je na važnije funkcije katjona (Ca2+, Mg2+, K+, Na+) i anjona (P3-, S2- Cl-) i posledice njihovog deficita ili suficita u obrocima. Date su formule za izračunavanje bilansa katjona i anjona u obrocima (BKAO) i praktični primeri njihove primene. Zaključeno je da se elektrohemijska reakcija u buragu, a time i u organizmu visokomlečnih krava može rešiti korišćenjem hraniva sa odgovarajućim odnosom katjona i anjona. Kada ne postoji mogućnost da se ovaj problem reši izborom hraniva, efikasan put je korišćenje preparata na bazi soli ili prirodnih mineralnih sirovina ( zeolit i bentonit i dr).
