INTERRELATION OF BASIC MINERAL METABOLIC INDICES IN KETOTIC COWS AND CALVES BORN FROM THEM

Abstract

A study on mineral metabolic indices in ketotic Black-and-White cows and calves born from them was conducted in Altai Territory. Two groups of cows were formed: the trial group of ketotic cows and the control group of apparently healthy cows. Two groups of calves were also formed: the trial group of calves born from ketotic cows and the control group of calves born from apparently healthy cows. The comparison of blood biochemistry indices obtained from cows and their calves has found the following in ketotic cows after calving: low total calcium level (2.26 ± 0.14 mmol/L), high concentrations of inorganic phosphorus (1.91 ± 0.12 mmol/L) and ketone bodies (2.26 ± 0.2 mmol/L) as compared to healthy herd-mates. The following has been found in the calves born from ketotic cows on the 10th day after birth: increased levels of ketone bodies (1.16 ± 0.1 mmol/L), inorganic phosphorus (3.12 ± 0.21 mmol/L) and total calcium (2.72 ± 0.18 mmol/L) as compared to those of the control herd-mates. High glucose level has been found in the calves born from ketotic cows during the first ten days after birth, which then decreased below that of the control calves.
