Evaluation of the effect of short-chain organic acids and probiotics on production performance, egg white quality, and fecal microbiota of laying hens

Effects of replacing Na selenite in laying hen feed with selenized glucose on production performance, egg quality, egg selenium content, microbial population, immunological response, antioxidant enzymes, and fatty acid composition

“…The dilution concentration from 10 −2 to 10 −5 for COL and from 10 −3 to 10 −6 for LAB counts were used. LAB counts were performed by plating the diluted samples on MRS agar and incubating them at 37°C for 48 h. Similarly, COL counts were conducted by plating the diluted samples on MacConkey agar and incubating them at 37°C for 24 h ( Rezaeipour et al, 2022 ).…”

The effect of replacing sodium selenite with selenium-chitosan in laying hens on production performance, egg quality, egg selenium concentration, microbial population, immunological response, antioxidant enzymes, and fatty acid composition

“…The dilution concentration from 10 −3 to 10 −6 for LAB and from 10 −2 to 10 −5 for COL counts were used. The LAB was grown for 48 h on MRS agar at 37°C, and the COL was cultivated for 24 h on MacConkey agar at 37°C ( Khajeh Bami et al, 2022 ; Rezaeipour et al, 2022 ).…”
