Comparison of the Dietary Supplementation of Lactobacillus plantarum, and Fermented and Non-Fermented Artemisia Annua on the Performance, Egg Quality, Serum Cholesterol, and Eggyolk-Oxidative Stability During Storage in Laying Hens

Artemisia annua L. is a widely distributed medicinal plant and well-known for treating malaria due to the artemisinin content. We previously found enhanced antioxidant and antibacterial activities of Lactobacillus plantarum-fermented A. annua dried leaves in vitro. The present study compared the effects of the dietary supplementation of L. plantarum, fermented (FA) or non-fermented (NFA) A. annua on laying performance, egg quality, serum cholesterol, and egg yolk oxidative stability during storage in 40-weeks-old Hy-Line Brown layers. In total, 180 layers were randomly allocated into four treatments for 6 weeks: basal diet (CON), basal diet + 0.5% L. plantarum only (LO), basal diet + 0.5% NFA, and basal diet + 0.5% FA. Each treatment comprised five replicates with nine birds each. Egg weight of NFA and FA groups were significantly higher as compared with the CON and LO groups (p 0.01). The FA group displayed higher Haugh unit (HU) compared with the NFA group (p 0.05). Eggshell color of the FA group was significantly increased compared with the other groups (p 0.01). There was no significant difference in triglyceride, total cholesterol, HDL-cholesterol, and VLDL+LDL cholesterol among the different groups. During egg storage, the HU of FA groups was significantly increased as compared with the CON group after 3 weeks storage (p 0.05). The malondialdehyde (MDA) content in the stored eggs was significantly lowered by feeding of FA as compared with the CON and LO groups (p 0.05). Altogether, the fermented A. annua displayed positive effects in promoting egg quality of layers.(AU)
