PSVI-2 Dietary Supplementation of Phyllanthus Urinaria Ameliorates Fatty Liver Hemorrhagic Syndrome in Hens

Abstract

Abstract The purpose of the present study was to investigate the effect of Phyllanthus urinaria supplement on fatty liver hemorrhagic syndrome (FLHS) in hens. Forty 7-week-old ISA hens were randomly divided into four groups (n = 10), including control diet group (CON), high cholesterol and low choline diet group (CLC), and CLC with 1% P. urinaria powder group (PU). CLC diet and the supplementation of P. urinaria for six weeks exhibited no impact on feed intake and body weight (P > 0.05). The triglyceride (TG) and the total cholesterol (TC) in plasma was increased at week 6 (TG: CON = 18.86 ± 0.97 mg/dL and CLC = 66.45 ± 7.17 mg/dL; TC: CON = 130.41 ± 5.87 mg/dL and CLC = 308.11 ± 27.97 mg/dL); nevertheless, P. urinaria decreased the triglyceride in plasma (PU = 41.19 ± 4.88 mg/dl, P < 0.05), but not total cholesterol (PU = 259.11 ± 20.88 mg/dL, P > 0.05). The malondialdehyde (MDA) concentration in plasma was decreased with 1% P. urinaria powder group (CLC = 64.81 ± 3.71 mg/dL and PU = 49.13 ± 4.20 mg/dL, P < 0.05). Under liver macroscopic analysis, PU demonstrated the least percentage of severe in hepatic appearance (CLC = 22% and PU = 0%). Similarly, the liver microscopic examination (H&E) suggested the PU supplementation reduced steatosis score (CLC = 2.89 ± 0.11 and PU = 2.11 ± 0.16) and blooning (CLC = 1.63 ± 0.22 and PU = 0.88 ± 0.31) in the hepatocyte. To sum up, this study revealed the hepatoprotective effect of Phyllanthus urinaria and provided a potential strategy for preventing FLHS to improve the welfare in hens.
