Special Issue Information

Dear Colleagues,

The gut microbiome and metabolome are closely associated with health and disease susceptibility, thereby influencing the performance of monogastric farm animals. The colonization, composition and function of the gut microbiome and metabolome start at the early stage of life and undergo drastic alterations later in life, reflecting long-term host health. Dysbiosis in the gut microbiome and metabolome composition can be affected by several factors, including diets, living environment, stressors and diseases, thereby declining sustainable livestock productivity.

Numerous nutritional strategies have gained growing interest in recent years to enhance livestock production through modulating the gut microbiome and metabolome. In this regard, an in-depth understanding of different nutritional strategies and their underlying molecular mechanisms relating to the microbiome and metabolome modulation will help us better understand their impact on animal health and production. In addition, deciphering the interrelationship between the gut microbiome and metabolome, and the overall health susceptibility of the host health through advanced omics techniques will provide new possibilities for improving the productivity of monogastric farm animals.

This Special Issue aims to collect up-to-date information about the recent studies on farm animal microbiome and metabolome relating to health, diseases and overall productivity.

This Special Issue welcomes publications focusing on any aspect of monogastric farm animal microbiome and metabolome, including animal productivity, animal behavior, feed additives, gut health, immunology or nutrition.

The effect of dietary inclusion of Moringa oleifera leaf powder (MLP) on the growth, meat quality, carcass characteristics, hematobiochemical profile, and cecal bacteria of broiler chicken was investigated in this research trial. In this study, 192-day-old Arbor Acre broiler chicks were assigned in a completely randomized design to three groups: control, antibiotic, and MLP. A standard basal diet was given to the control group, while the antibiotic group received 75 mg/kg chlortetracycline, and the MLP group received 100 mg/kg M. oleifera leaf powder supplemented basal diet. Each group was further divided into eight replicates consisting of eight birds each, and the trial ran for 35 days. Among the groups, the MLP-fed broilers achieved the highest final body weight (FBW), average daily gain (ADG), and average daily feed intake (ADFI). Notably, the FCR for the whole experimental period was lower in the MLP group, indicating a more efficient use of feed for growth. Supplementation of MLP with basal diet significantly increased (p < 0.05) the weight of thighs and drumsticks relative to live weight %, while the spleen and abdominal fat weight (% of live weight) were significantly decreased (p < 0.05). Adding MLP to the diet improved the meat quality of broilers, as indicated by the highest pH of meat at 45 min and the lowest cooking loss (%) observed in this group. MLP exhibited hypocholesterolemic and hypolipidemic effects, with the lowest total cholesterol and triglyceride levels compared to non-supplemented groups. The hematological profile revealed that the MLP group exhibited the highest RBC count and Hb level, while also showing the lowest H/L ratio. Moringa supplementation significantly (p < 0.05) modulated the cecal bacterial population, reducing pathogenic E. coli and Shigella spp. while increasing beneficial Lactobacillus spp. and the total aerobic plate count (TAPC). In conclusion, Moringa oleifera leaf powder (MLP) can be used as a natural feed supplement for promoting the growth, meat quality, healthy blood, and sound health of broilers. Full article

Our previous study demonstrated that moderate inhibition of intestinal autophagy was beneficial to alleviate early weaning stress in piglets, but the detailed mechanism behind this was unclear. Microbiota-mediated enterocyte autophagy helps maintain intestinal homeostasis. This study investigated the effects of inhibition or activation of autophagy in intestinal microbial community compositions and metabolite profiles in piglets. Eighteen 24-day-old weaned piglets were divided into three groups (each treatment of six piglets) and treated daily with rapamycin (RAPA), chloroquine (CQ) or a control volume of normal saline (CON group). Before the formal trial, the piglets were allowed to acclimatize for 3 days, and then the trial period was 14 days. Collected samples from the ileum and colon underwent 16S rRNA gene sequencing and metabolite analysis. Significant differences in microbial composition were observed in both the ileum and colon of the RAPA and CQ groups compared to the CON group (p < 0.05). In addition, the relative levels of abundance of Peptostreptococcus, Fusobacterium, Dialister, Selenomonas and Oceanobacillus in the ileum and Porphyromonas, Bacteroides, unidentified_Lachnospiraceae, Akkermansia, Sharpea, Peptococcus, Pseudoalteromonas, Peptoclostridium and unidentified_Acidobacteria in the colon were improved in piglets fed the RAPA diet, whereas the relative levels of abundance of Turicibacter, Rickettsiella and Sarcina in the ileum and Roseburia and Kroppenstedtia in the colon were enhanced in the CQ group (p < 0.05). Meanwhile, metabolomic analysis showed that there were significant differences in metabolites among all groups (p < 0.05), and KEGG enrichment analysis revealed that differential metabolites were mainly enriched in the ABC transporters and biosynthesis of amino acids pathways. Furthermore, these metabolites were closely related to differential microorganisms (p < 0.05). Overall, autophagy inhibition regulates the composition of intestinal microorganisms and their metabolites, and these differential metabolites are significantly correlated with differential intestinal microorganisms, which may in turn affect the production performance of weaned piglets.
