The average daily weight gain (ADG) is considered a crucial indicator for assessing growth rates in the swine industry. Therefore, investigating the gastrointestinal microbiota and serum metabolites influencing the ADG in pigs is pivotal for swine breed selection. This study involved the inclusion of 350 purebred Yorkshire pigs (age: 90 ± 2 days; body weight: 41.

The epigenetic regulation mechanism of porcine skeletal muscle development relies on the openness of chromatin and is also precisely regulated by transcriptional machinery. However, fewer studies have exploited the temporal changes in gene expression and the landscape of accessible chromatin to reveal the underlying molecular mechanisms controlling muscle development. To address this, skeletal muscle biopsy samples were taken from Landrace pigs at days 0 (D0), 60 (D60), 120 (D120), and 180 (D180) after birth and were then analyzed using RNA-seq and ATAC-seq.

Piglets are susceptible to weaning stress, which weakens the barrier and immune function of the intestinal mucosa, causes inflammation, and ultimately affects animal growth and development. Ellagic acid (EA) is a natural polyphenol dilactone with various biological functions. However, The mechanisms underlying the effects of EA on animal health are still poorly known.

Article Synopsis
  • The study investigates the genetic factors affecting litter size in Guangxi Bama Xiang pigs using SNP data and phenotypic analysis of average born numbers across multiple parities.
  • Through the application of Fixation index (Fst) methods and general linear models, researchers identified 25 significant SNPs as selection signatures related to litter size, specifically focusing on the VEGFA gene.
  • The findings highlight two notable mutations in the VEGFA promoter, suggesting their potential as molecular markers for improving litter size in pig production.

Article Synopsis
  • The study investigates the metabolic and physiological changes in the blood of Bama miniature pigs aged 6 to 12 months, commonly used in medical research, to understand growth differences.
  • Blood samples were collected and analyzed for 20 physiological indices, revealing no significant age-related differences in most indices, though some increased with age.
  • Notable findings include the identification of 14 and 25 significant differential metabolites between 6M/12M and 8M/12M old pigs, respectively, particularly in amino acid metabolism, suggesting that amino acids play a crucial role in the growth of these pigs as they age.

Litter size and teat number are economically important traits in the porcine industry. However, the genetic mechanisms influencing these traits remain unknown. In this study, we analyzed the genetic basis of litter size and teat number in Bama Xiang pigs and evaluated the genomic inbreeding coefficients of this breed.

In China there are approximately 100 pig breeds, which show great diversity in their appearance. However, information on genome selection signatures, such as spine curvature, is scarce. Therefore, we used the fixation index (F ) and cross-population extended haplotype homozygosity (XPEHH) methods to explore the genome selection signatures of spine curvature in six breeds of Chinese indigenous pig.

Article Synopsis
  • * The study compared healthy follicles (HFs) and atretic follicles (AFs) in Bama Xiang pigs, analyzing hormonal concentrations and gene expressions between the two groups.
  • * Results indicated that AFs had lower estradiol but higher progesterone levels compared to HFs, with distinct differences in gene expression and identified 18 differential metabolites linked to metabolic pathways; disorders in amino acid and bile acid metabolism may play a role in follicular atresia.

Article Synopsis
  • This study investigates how fecal microbiota in young pigs affects their feed efficiency, which can help lower breeding and production costs.
  • Ninety-one pigs were categorized based on their residual feed intake (RFI), and fecal samples were analyzed for microbial diversity and composition using 16S rRNA sequencing.
  • The findings revealed that pigs with higher feed efficiency (lower RFI) had a different composition of gut bacteria, which might enhance gut health and amino acid metabolism, suggesting potential targets for improving pig feed efficiency through dietary strategies.
