• who: ufeffJiamingufeff ufeffLiufeff from the Guangdong Academy of Agricultural Sciences (GDAAS), China Aristotle University of Thessaloniki, Greece have published the Article: Effects of rare earth as feed additive on production performance, egg quality, serum biochemical parameters, antioxidant capacity, intestinal morphology, and gut microbiota in late-phase laying hens, in the Journal: Gut microbiota analysis was performed as described in our previous study (Zeng et_al, 2021). Briefly, genomic DNA was extracted, followed by bacterial 16S rRNA gene amplification. PCR products were mixed in equidensity ratios and purified. 16S rRNA sequencing was performed on an Illumina HiSeq2500 PE250 platform . . .
