Following publication of the original article (Yang et al. 2021), the authors identified some errors in Fig. 1 and Fig. 7. The correct figures are given below.

Fig. 1
figure 1

Effects of different NaCl contents in drinking water on hematocrit (HCT) and ascites heart index (AHI) of broilers. They were randomly divided into four groups: a control group (deionized water, NaCl at 0 g/L), a freshwater group (FW, deionized water + NaCl at 1 g/L), high salinized freshwater group 1 (H-SFW-1, deionized water + NaCl at 2.5 g/L) and high salinized freshwater group 2 (H-SFW-2, deionized water + NaCl at 5 g/L). a AHI (RV/TV, right ventricular weight/total ventricular weight) of broilers in control group, FW group, H-SFW-1 group and H-SFW-2 group. (n = 10, ** P < 0.01 vs. control). b HCT of broilers in control group, FW group, H-SFW-1 group and H-SFW-2 group (n = 10, ** P < 0.01 vs. control)

Fig. 7
figure 2

Effect of dopamine receptor D4 (DRD4) on angiotensin II type 1 receptor (AT1) protein expression in primary vascular smooth muscle cells (VSMCs) of broilers. VMSCs were incubated with different doses of D4A or D4I for 24 h. a, b, c Dose-dependent effect of D4A (HY-101384A) or D4I (HY-B0965) (n = 6, **P < 0.01 vs. control). a, d, e The dose-dependent effect of D4A or D4I (n = 6, **P < 0.01 vs. control)

The original article (Yang et al. 2021) is updated.
