Effect of cage stress on mRNA expression of CHOP (a) and GRP78 (b) genes in the liver of Shaoxing ducks. Relative expression was normalized to the expression of β-actin. Vertical bars represent the mean ± S.E. (n = 5). RF ducks = reared on the floor, RC ducks = reared in the cage. a,b,cDifferent superscripts within columns indicate means are significantly different. The labels 1, 2, 4, 7, and 10 d indicated the days in the cage
