This experiment was conducted to investigate the effects of colistin on electrolytes homeostasis of blood and its underlying mechanism in early weanling piglets,Forty piglets,weaned at 21 d postnatal were assigned to 2 groups,representing supplementation with 0 or 0.

A method was established to simultaneously detect colistin,bacitracin,virginiamycin residues in animal tissues,such as muscle,liver and kidney,by liquid chromatography tandem mass spectrometry.
