  • Title: [Buffer systems, protein and electrolyte levels and erythrocyte indices in calves fed with beestings and milk substitutes].
    Author: Hejłasz Z, Nicpoń J.
    Journal: Pol Arch Weter; 1984; 24(2):229-37. PubMed ID: 6537494.
    Abstract:
    By the method of Astrup were determined: pH of the blood, HCO3, act. pCO2, PO2, BB, BE, SO2, in a flame photometer: the concentration of Na+, K+, Ca++, Mg++, erythrocyte indices by the methods commonly used. Calves from cows fed with balanced feeds were born in a state of breathing acidosis at blood pH about 7.30 and at 26 mEq of bicarbonates concentration. Calves from cows fed with ensilages were born in a state of metabolic acidosis with blood pH 7.14 and HCO-3 act. - 14 mEq. Feeding with beestings alkalized the blood, increasing its pH from 0.06 to 0.11 and the concentration of bicarbonates which are the main regulators of acid-basic equilibrium in newborn calves. The concentration of sodium, potassium, calcium, chlorides and protein increased slightly despite a distinct hydration of the blood. Administration of a milk-substitute aggravated acidification of the organism and caused passing of physiological breathing acidosis to the state of metabolic acidosis. On using the milk-substitute, hydration of the blood occurred and the level of the other parameters determined decreased. Milk-substitutes should not be given calves in their early period of life.
