Abstract

An increase in neutrophil-to-lymphocyte (N/L) ratio with a marked increase in neutrophils and a decrease in lymphocytes was observed on arrival, and the increased N/L ratio returned approximately to the normal level 1 week after arrival. The serum cortisol level markedly increased on the day of arrival and it returned to normal 1 week after arrival. These findings indicate that the transport process was stressful for animals, showing increases in N/L ratio as well as cortisol level.
