mRNA expressions of the histamine receptor genes H1R, H2R, H3R and H4R in the mammary tissues of dairy cows in the LC and HC groups. The ordinate axis indicates the relative expression of histamine receptors in mammary gland tissues (n = 6 in each group, mean ± SEM). The white packed column represents the LC group, while the black packed column represents the HC group. The significant differences are indicated (*P < 0.05, **P < 0.01)
