In the balance experiment digestibility and retention of crude protein
in two groups of pigs, differently responding to the halothane test (
HAL+ and HAL-), were observed. In the HAL- group we found out higher d
igestibility coefficients for calcium and phosphorus (P > 0.05). For m
agnesium and sodium the digestibility coefficients were higher for the
animals of the HAL+ group, significantly higher for sodium (P < 0.05)
. Higher calcium secretion in the faeces of animals in the HAL+ group
(P < 0.05) was confirmed, which caused higher calcium retention in the
HAL- group (P < 0.05). In the group presented the above retention was
higher by 0.538 g. Higher magnesium retention in the group of pigs, r
esponding to halothane positively, was caused by lower level of secret
ion urine (P > 0.05). Larger amount of phosphorus was secreted in urin
e by animals of the HAL+ group (P < 0.05). The results obtained in the
balance experiment refer to important relations of macroelements obse
rved in metabolism of pigs, positively responding to halothane anesthe
sis.
