[Objectives] To explore the effects of Abrus cantoniensis Hance (ACH) extract on blood lipid indicators of laying hen fed with high energy and low protein diet. [Methods] Sixty 90-day-old laying hens were randomly divided into five groups: the blank control group (basic diet), the model group (high-energy and low-protein diet, HELPD), the low-dose group (HELPD+0.5 g ACH extract per hen, LACH), and the medium-dose group (HELPD+1 g ACH extract per hen, MACH), high dose group (HELPD+2 g ACH extract per hen, HACH). The ACH extract was administrated by drinking water for 48 d. [Results] Different doses of ACH could improve the pathological changes induced by high energy and low protein. ACH extract had no significant effect on blood routine indicators of laying hens (P>0.05). The contents of total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in the model group were significantly higher than those in the control group (P<0.05), while the content of high density lipoprotein cholesterol (HDL-C) was significantly lower than that in the control group (P<0.05). There was no significant difference in blood lipid between LACH group and model group (P>0.05). In MACH and HACH groups, the contents of TC, TG and LDL-C were significantly lower than those in the model group (P<0.05), and the content of HDL-C was significantly higher than that in the model group (P<0.05). [Conclusions] The ACH extract can regulate the HELPD-induced dyslipidemia in laying hens. |
