Gut microbiota plays an important role in pig health and production. Still, availability of sequenced genomes functional information for most gut microbes remains limited. Here we perform a landscape survey the swine microbiome, spanning extensive sample sources by deep metagenomic sequencing resulting expanded gene catalog named integrated (PIGC), containing 17,237,052 complete genes clustered at 90% protein identity from 787 metagenomes, which 28% are unknown proteins. Using binning...
Abstract Background Excessive fat accumulation of pigs is undesirable, as it severely affects economic returns in the modern pig industry. Studies humans and mice have examined role gut microbiome host energy metabolism. Commercial Duroc are often fed formula diets with high protein contents. Whether how under this type diet regulates swine largely unknown. Results In present study, we systematically investigated correlation lean meat percentage (LMP) 698 commercial found that Prevotella...
Gut microbiota plays fundamental roles in energy harvest, nutrient digestion and intestinal health, especially processing indigestible components of polysaccharides diet. Unraveling the microbial taxa functional capacity gut microbiome associated with feed efficiency can provide important knowledge to improve pig swine industry. In current research, we studied association fecal 280 commercial Duroc pigs. All experimental pigs could be clustered into two enterotype-like groups. Different...
Abstract Uncovering the phylogenetic composition of microbial community and potential functional capacity microbiome in different gut locations is great importance to pig production. Here we performed a comparative analysis microbiota metagenomics among jejunum, ileum cecum pigs with distinct fatness. 16S rRNA gene sequencing revealed dramatic differences composition, diversity species abundance between small intestine cecum. Clostridium SMB53 were enriched intestine, while Prevotella ,...
The gut microbiota impacts on a range of host biological processes, and the imbalances in its composition are associated with pathology. Though understanding contribution many factors, e.g. gender, diet age, development has been well established, dynamic changes phylogenetic interaction networks along age remain unclear pigs.Here we applied 16S ribosomal RNA gene sequencing, enterotype-like clustering (Classification microbiome into distinct types) co-occurrence network to explore pig...
There are growing evidences showing that gut microbiota should play an important role in host appetite and feeding behavior. However, what kind of microbe(s) how they affect porcine remain unknown.In this study, 280 commercial Duroc pigs were raised a testing station with the circadian behavior records for continuous period 30-100 kg. We first analyzed influences gender genetics average daily feed intake (ADFI), but no significant effect was observed. found Prevotella-predominant enterotype...
Intramuscular fat (IMF) that deposits among muscle fibers or within cells is an important meat quality trait in pigs. Previous studies observed the effects of dietary nutrients and additives on improving pork IMF. Gut microbiome plays role host metabolism energy harvest. Whether gut microbiota exerts effect IMF remains unknown. In this study, we investigated microbial community structure 500 samples from porcine cecum feces using high-throughput 16S rRNA gene sequencing. We found...
Abstract Vertnin ( VRTN ) variants have been associated with the number of thoracic vertebrae in European pigs, but association has not evidenced Chinese indigenous pigs. In this study, we first performed a genome-wide study Erhualian pigs using one candidate causative mutation and Illumina Porcine 60K SNP Beadchips. The is significantly vertebral population. We further show that pleiotropic desirable effects on teat carcass (body) length across four diverse populations, including Erhualian,...
Microbial community in gastrointestinal tract participates the development of obesity as well quite a few metabolic diseases human. However, there are studies about relationship between gut microbiota and porcine fatness. Here, we used high-throughput sequencing to perform 16S rRNA gene analysis 256 cecum luminal samples from Erhualian pigs 244 stools Bamaxiang pigs, adopted two-part model statistical method evaluate association microbes with As results, identified total 6 108 operational...
Pigs are a perfect model for studying the interaction between host genetics and gut microbiome due to high similarity of gastrointestine digestive system with humans, easily controlled feeding conditions. In this study, two pig populations which were raised in uniformed farm conditions provided same commercial formula diet used as experimental animals. A systematical investigation genetic effect on microbial composition was separately performed porcine cecum lumen feces samples through...
Understanding how the gut microbiome and short chain fatty acids (SCFAs) affect finishing weight is beneficial to improve meat production in rabbit industry. In this study, we identified 15 OTUs 23 microbial species associated with using 16S rRNA gene metagenomic sequencing analysis, respectively. Among these, butyrate-producing bacteria of family Ruminococcaceae were positively weight, whereas taxa related intestinal damage inflammation showed opposite effects. Furthermore, interactions...
Feed efficiency (FE) is an economically important trait in pig production. Gut microbiota plays role energy harvest, nutrient metabolism, and fermentation of dietary indigestible components. Whether which gut microbes affect FE pigs are largely unknown. Here, a total 208 healthy Duroc were used as experimental materials. Feces serum samples collected at the age 140 d. We first performed 16S rRNA gene metagenomic sequencing analysis to investigate relationship between microbiome porcine...
The size and type of ears are important conformation characteristics that distinguish pig breeds. A significant quantitative trait locus (QTL) for ear has been identified on SSC5 (SSC Sus scrofa chromosome) but the underlying causative gene mutation remain unknown. Thus, our aim was to identify responsible enlarged in pig.First, we narrowed down QTL region a 137.85-kb interval harbors only methionine sulfoxide reductase B3 (MSRB3) gene. Then, 38.7-kb copy number variation (CNV) affects last...
The mammalian intestinal tract harbors diverse and dynamic microbial communities that play pivotal roles in host health, metabolism, immunity, development. Average daily gain (ADG) is an important growth trait meat rabbit industry. effects of gut microbiota on ADG rabbits are still unknown.In this study, we investigated the distribution commercial Ira from weaning to finishing uncover relationship between average via 16S rRNA gene sequencing. results indicated richness diversity...
Summary Under natural farming, environmental pathogenic microorganisms may invade and affect swine lungs, further resulting in lung lesions. However, few studies on microbiota their potential relationship with lesions were reported. Here, we sampled 20 pigs from a hybrid herd raised under conditions; recorded lung‐lesion phenotype investigated microbial communities by sequencing the V3‐V4 region of 16S rRNA gene for each individual. We found reduced diversity but more biomass severe‐lesion...
More and more studies have indicated that gut microbiota takes part in the biosynthesis metabolism of sex hormones. Inversely, hormones influence composition microbiota. However, whether vagina is associated with estrus return weaning sows largely unknown. Here, using 16S rRNA gene sequencing 158 fecal 50 vaginal samples, we reported shifts between normal non-return sows. In Lactobacillus S24-7 were enriched sows, while Streptococcus luteciae , Lachnospiraceae, Clostridium Mogibacterium had...
In this study, we investigated the variations in production performance, health status, and gut microbiota of meat rabbits raised semi-confined barn during summer winter. Compared to summer, reared winter possessed significantly higher slaughter weight carcass weight. Rabbits fed were more vulnerable different stressors, which led increased protein levels HSP90, IL-1α, IL-1β, IL-2, concentrations MDA, but declined GSH SOD activities. Additionally, significant differences microbial...
Weaning weight is an important economic trait in the meat rabbit industry. Evidence has linked gut microbiota to health and production performance rabbits. However, effect of on weaning remains unclear. In this study, we performed 16S rRNA gene sequencing analysis 135 faecal samples from commercial Ira We detected 50 OTUs significantly associated with weight. that showed positive associations were mostly members family Ruminococcaceae which are degrading dietary fibres producing butyrate.
