摘要

Mulberry leaves contain high concentrations of polyphenolics and the flavonol glycoside, and have reported that they have pharmacological activity such as the anti-bacterial, anti-oxidant, anti-hypoglycemic, anti-cancer, anti-obesity, anti-ER stress, and anti-inflammatory activities. Moreover, fermentation can increase the nutritional value of this raw material and bioactive components. Studies have found that adding fermented mulberry leaves into feeds could enhance immunity, regulated lipid metabolism, and improved the quality of animal products. The study aims to explore the effects of fermentation of mulberry leaves on the growth performance, serum biochemistry, and lipid metabolism of broilers. Based on the results of sample fermentation colony-forming-unit, total phenol and total flavonoid contents, mulberry leaves fermented with Lactobacillus plantarum for 48 hours were selected for animal testing. A total of 320 one-day-old Ross308 broilers were randomly divided into the basal diet (Control), 0.5%, 1%, and 2% fermented mulberry leaves (FML) supplementation in the diets for 35 days. The results showed that 2% FML significantly increased BW and BWG, and significantly improved FCR in the early stage. In terms of serum biochemical results, the 1% and 2% FML groups significantly decreased serum GLU, SGOT, and LDL-C, and significantly increased the HDL-C. The 2% FML group significantly decreased TP, ALB, GLO and TG content. In conclusion, the FLM improve early growth and serum biochemistry, with the most significant benefits observed in the 2% FLM group.
