Decrease of plasmatic aldosterone of growing half–bred zebu calves
It was suggested that the growth delay of early–weaned calf wouldbe attributed to stress. In this case, plasmatic increases of aldosterone concentration shouldhave occurred. To prove this hypothesis, values of this hormone were determined in 120 half–bred zebu calves (2 months old, 50% each sex). Si...
