Fig. 1From: The dopamine receptor D4 regulates the proliferation of pulmonary arteries smooth muscle in broilers by downregulating AT1REffects 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.
