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 ,...
Abstract Resequencing a number of individuals various breeds as reference population and imputing the whole-genome sequences that were genotyped with medium-density chips to perform an association study is very efficient strategy. Previously, we performed genome-wide (GWAS) lumbar using 60K SNPs from porcine Illumina in 418 Sutai pigs did not detect any significant signals. Therefore, imputed 403 deeply resequenced tests. We identified quantitative trait locus (QTL) for SSC1 P value 9.01E-18...
Gestation length (GL) is a critical indicator of reproductive performance in sows and closely associated with other traits, such as total number born (TNB) alive (NBA). Despite its importance, the genetic mechanisms underlying GL impact on traits remain poorly understood. In this study, we investigated relationship between using 7013 farrowing records conducted an imputed whole-genome sequence-based genome-wide association study (GWAS) for first-parity sows, involving 3005 French Large White...
Intestinal probiotics significantly regulate the growth performance of their host, with composition being influenced by various factors. While many studies have explored how gut microbiota affects traits such as body weight and BMI, research on host genetic factors, subsequent impact performance, remains limited. To address this gap, we collected fecal tissue samples, well phenotypic data, from 193 Yunong black pigs at 280 days age. We then sequenced genotyped all subjects using 50K SNP...
Feed conversion ratio (FCR) is a key indicator of pig productivity, but its measurement labor-intensive and time-consuming. This study aimed to construct predictive model for cumulative feeding intake (CFI), which could help estimate FCR more efficiently reduce the time effort needed measurements. included total 987 Yorkshire boars raised in specific pathogen-free environments, with growth data collected using automatic feeders. The segmented R package Bayesian ridge regression (BRR) were...
The whole-genome sequences of progenies with low-density single-nucleotide polymorphism (SNP) genotypes can be imputed high accuracy based on the deep-coverage key ancestors. With this imputation technology, a more powerful genome-wide association study (GWAS) carried out using variants and phenotypes interest to overcome shortcomings low-power detection large confidence interval derived from SNP markers in classic studies. In study, 19 ancestors large-scale swine F2 White Duroc × Erhualian...
The accelerated aging of the global population has emerged as a critical public health concern, with increasing recognition influential role played by microbiome in shaping host well-being. Nonetheless, there remains dearth understanding regarding functional alterations occurring within microbiota and their intricate interactions metabolic pathways across various stages aging. This study employed comprehensive metagenomic analysis encompassing saliva stool samples obtained from 45 pigs...
Summary A large proportion of gilts and sows are culled from reproduction populations because anestrus pubertal reproductive failure. Selecting early onset puberty has a favorable effect on sows’ reproductivity. However, age at is hard to be routinely measured in commercial herds. With molecular genetic predictors, identifying individuals that have propensity for can simplified. We previously performed genome scanning genome‐wide association study an F2 resource population using 183...
Abstract. In this study, we used electronic feeding station observations of pigs to investigate their growth performance and behavior. These were raised in Xinda Livestock Company Ltd. Henan, China, followed the Chinese directive for protection farm animals. Electronic stations are often pig breeding identifying loci associated with feed consumption. Moreover, they can also provide much valuable information on behavior that could be directly improve production efficiency. This study involves...
