Abstract:

Experiments were conducted to study the effect of Flammulina velutipes stembase (FVS) on serum biochemical
indexes, abdominal fat, and lipid contents in liver and muscle of broilers. A total of 270 one-day-old Arbor Acres broilers
were randomly divided into 5 groups with 3 replicates of 18 chickens each: control group (basal diet), antibiotic group (basal
diet + 5 mg/kg flavomycin), and FVS groups at 3 levels (basal diets containing 2%, 4% and 6% FVS). The experimental
period lasted 42 days. The results showed that: 1) dietary supplementation with 2% and 6% FVS significantly decreased
serum triglyceride (TG) (P < 0.05); 2) FVS at each concentration significantly reduced serum total cholesterol (TC)
(P < 0.05), and increase the content of leptin (LEP) in serum (P < 0.05), although having no obvious effect on high density
lipoprotein (HDL-C) or low density lipoprotein (LDL-C) (P > 0.05); 3) different treatment groups revealed a significant
increase in the body weight of broilers (P < 0.05) and a reduction of lipid contents in liver, thigh muscle, and breast
muscle although no significant effect on the excreta of broiler was found (P > 0.05); 4) the abdominal fat deposition was
significantly reduced in the broilers fed with 4% and 6% FVS (P < 0.05), and the activity of HSL was significantly enhanced
in the broilers fed with 2% and 6% FVS (P < 0.05). These results suggested that FVS could reduce serum lipid and lipid
deposition in broilers.
