Next Generation Sequencing of ileum in broiler infected with S. pullorum. Next Generation Sequencing of ileum in broiler infected with S. pullorum

This study was conducted to evaluate the effects of dietary supplemental magnolol and honokiol in broilers infected with S. pullorum. A total of 360 one-day-old broilers were selected and randomly divided into four groups with six replicates: the negative control group (CTL), S. pullorum-infected group (SP), and the S. pullorum-infected group supplemented with 300 mg/kg honokiol (SPH) or magnolol (SPM). Chicks in the SP, SPH, and SPM groups were orally treated with a 0.5 ml (4×108 CFU/mL) S. pullorum solution at 5 days of age, while chicks in the control (CTL) group received the same amount of sterilized PBS at the same age.At 14 and 21 days of age, one chick from each replicate was randomly selected to be weighed and slaughtered by jugular exsanguination after a 12-h fasting period. The ileum samples were collected to analyze the differential expression genes. Overall design: Examination of gene in ileum microbiota of broiler infected with S. pullorum with or without magnolol and honokiol supplementation.
