In this descriptive study, our findings revealed the PKCθ MedChemExpress alterations within the host transcriptome expression profile while feeding an antibioticfree diet and recommended that feeding an antibiotic-free diet plan alters the host’s metabolic network and the expression of antiviral proteins. Abstract: China officially promulgated the announcement of banning the usage of antibiotics in the animal business in 2020. However, the prohibition of antibiotics inside the animal market would minimize the feed conversion rate and boost the mortality of animals. So as to receive details about the pathogenesis and host immune response of rabbits with diarrhea just after becoming fed an antibioticfree diet regime, we initial analyzed the intestinal tissue sections of rabbits. Secondly, the gene expression differences of rabbit intestinal segments have been analyzed by high-throughput sequencing. Our evaluation identified 168, 593, 2069, 334, 321, and 1423 DEGs in the comparison groups S_Z (the duodenum of healthy rabbits) vs. S_B (diarrhea within the duodenum of rabbits), K_Z (healthier rabbit jejunum) vs. K_B (rabbits with diarrhea within the jejunum), H_Z (healthful rabbit ileum) vs. H_B (rabbits with diarrhea within the ileum), M_Z (healthful cecum of rabbits) vs. M_B (rabbits with diarrhea inside the cecum), J_Z (healthy rabbit colon) vs. J_B (colon of rabbits with diarrhea), and Z_Z (wholesome rabbit rectum) vs. Z_B (rectum of rabbits with diarrhea), respectively. The reproducibility and repeatability on the final results have been validated by RT-qPCR. Enrichment analyses of GO annotations and KEGG pathways revealed the host DEGs which might be potentially associated to acute inflammation, pressure response, tissue dehydration, adaptive immune response, protein binding, activation of related enzymes, migration of immune cells, and so on. In this descriptive study, our findings revealed the alterations within the host transcriptome expression profile right after feeding an antibiotic-free diet and suggested that feeding an antibiotic-free diet plan alters the host’s metabolic network and also the expression of antiviral proteins, which offers a theoretical basis for further study around the immune response of animals fed an antibiotic-free diet.Publisher’s Note: MDPI stays neutral with regard to jurisdictional δ Opioid Receptor/DOR web claims in published maps and institutional affiliations.Copyright: 2021 by the authors.

Introduction Since the first use of antibiotics in piglets and chickens in 1949, it has been identified that feeding diets containing antibiotics could maintain animal intestinal health and minimize livestock mortality [1,2]. Even so, feeding an antibiotic diet would gradually weaken the immune ability of animals, causing animal resistance to antibiotics and forming a vicious circle, and major to human well being challenges triggered by antibiotic residues in meat [3]. Consequently, the animal sector and also the customer market had been increasingly calling for the abolition of the use of feed antibiotics [4,5]. For instance, Sweden, the European Union, and China banned the use of antibiotics in
