Effect of antibiotic treatment of young calves on glucose absorption and some plasma components.

Oral treatment of 10-15 day-old calves with either chloramphenicol (55 mg/kg body wt) or tetracycline (11 mg/kg body wt) did not induce diarrhoea. Treatment caused significant elevation of plasma Na+, K+ and total protein. Calves treated with chloramphenicol showed retarded glucose absorption from the gut.
