A. Michna et al., METABOLIC-ACIDOSIS OF CALVES SUFFERING FR OM DIARRHEAS AND ITS TREATMENT WITH NAHCO3 APPLICATION, Veterinarni medicina, 41(10), 1996, pp. 305-310
Sixteen head of 7 to 10 days old calves of the Black-Pied breed with c
linical diagnosis of gastroenteritis acuta were examined for their cli
nical and laboratory findings before i.v. application of 8.4% solution
of NaHCO3 and after it, using the well-known formula: live weight in
kg x 0.6 x base deficit. The calves presented clinical symptoms of sev
ere dehydration with profuse diarrhea. Dominant symptoms of the calf d
ehydration syndrome involved enophthalmos, lying down, lowered surface
body temperature and strong exsiccosis of the organism. The values of
pH, PCO2, HCO3, ABE, SBC were determined as acid-base indicators in v
enous blood. The most important adjustment of acid-base indicators was
observed in pH, ABE and SB; their increases were statistically signif
icant within the 3rd and/or 24th hour after intravenous application of
8.4% NaHCO3 solution at a significance level of p < 0.05 and/or p < 0
.01. Buffering capacity of NaHCO3 was relatively strongly reflected in
all indicators under observation when they were determined as referen
ce values in 24 hours after application. The adjustment of acid-base i
ndicators was accompanied by general improvement of calf health while
the sucking reflex was resumed, which provided the conditions for acce
lerated replacement of fluids and electrolytes by i.v. as well as p.o.
application forms.
