Summary: This study investigated the effect of different n-6/n-3 polyunsaturated fatty acid (PUFA) ratios on serum fatty acid composition, microbiota, and their metabolites in the intestine of pigs. The results showed that a lower dietary n-6/n-3 PUFA ratio improved serum fatty acid composition and metabolome-microbiome responses in Heigai pigs. This study provides new insights into regulating pig metabolism and understanding the interaction between host and microbes in pigs.

Summary: This study analyzed the phospholipid class contents and composition in the biceps femoris of Iberian pigs under different rearing systems (Montanera vs Pienso). The results showed that certain phospholipids, such as phosphatidylcholine, phosphatidylethanolamine, cardiolipin, and sphingomyelin, had higher levels in Montanera pigs compared to Pienso pigs, which may partially explain the sensory differences in dry-cured ham between the two systems.

Summary: Cold exposure affects meat quality, fatty acid composition, and transcriptional changes in skeletal muscle of pigs, showing changes in individual fatty acid proportions, gene expression related to fatty acid biosynthesis, and mitochondrial beta-oxidation. The lipid metabolism in cold-exposed muscle is regulated by lipoprotein particle, extracellular matrix, and PPAR signaling pathways, indicating the potential of cold exposure to regulate lipid metabolism in farmed animals.

Summary: It was found in the study that the supplementation of gilts with n-3 and n-6 enriched diets had significant effects on serum composition, fatty acid levels, and offspring weight compared to the control group. Offspring from gilts supplemented with n-3 had higher body weight, increased daily weight gain, and higher serum EPA levels. These results demonstrate the beneficial effects of PUFA-enriched cow's milk supplementation for the offspring of gilts.

Summary: Previous studies have shown that a high-fat diet contributes to liver fibrosis progression, and recent research focuses on the effects of different fat sources on non-alcoholic steatohepatitis. Specifically, trans fatty acid (TFA) and cholesterol-rich diets, but not saturated fatty acid (SFA) diets, have been found to significantly contribute to hepatic fibrosis in animal models.

Summary: In this study, the effects of multispecies probiotics on the gut microbiome of pigs fed with low protein diet were investigated. The results showed that multispecies probiotics could modulate the composition, function, and metabolites of the gut microbiome in pigs. The supplementation of multispecies probiotics enhanced the production of short-chain fatty acids and polyamines, and upregulated the pathways for protein digestion and utilization in the gut.

Summary: Fatty acid desaturase (FAD) plays important roles in plant growth, development, and defense processes. In this study, we identified and classified 27 MaFAD genes into five subfamilies based on amino acid sequence similarities. The expansion of the MaFAD gene family is mainly attributed to segmental duplication events. We also discovered miRNAs targeting MaFADs and various regulatory elements in their promoters, indicating the complex regulation of MaFAD expression. Furthermore, gene expression analysis revealed significant differential expression of MaFADs under high and low temperature, as well as the influence of FocTR4 and S. indica on MaFAD expression and fatty acid accumulation in banana roots. Overall, our study highlights the importance of MaFADs in banana's response to temperature stress and fungal colonization.

Summary: Fat metabolism is an important process in meat production companies, which affects the quality of meat. The source and incorporation rate of fat differ in different growth phases. The liver plays a critical role in fat metabolism during the fattening phase. Leaner pigs rely more on dietary fatty acids for fat deposition compared to fatter pigs. The activity of stearoyl-CoA desaturase is higher in the fattening phase.

Summary: In this study, a missense polymorphism in the AGPAT5 gene was found to be significantly associated with fat content and composition traits in pigs. The variant showed positive effects on intramuscular fat content and fatty acid composition. The impact of the variant on fat content was more pronounced in fatter pigs and it interacts with other genes that affect overall fatness.

Summary: It has been found that gene expression can be blocked by methylation during gametogenesis, resulting in unequal genetic contribution from parents to offspring. The study on a population of Purebred Spanish (PRE) horses revealed that both maternal and paternal gametic effects influence reproductive and morphological traits. The maternal gametic effect generally has a stronger influence on most traits.

Summary: INGA FOOD, S.A. conducted a crossbreeding program to produce hybrid pigs, and studies revealed differences in litter size between reciprocal crosses, suggesting the presence of genomic imprinting effects. A multivariate gametic model was introduced to estimate the gametic correlations between paternal and maternal effects from different genetic backgrounds. The results showed distinct differences in the posterior distribution of gametic correlations between the two populations, which may explain the performance outcomes in the reciprocal crosses.

Summary: This study provides new insights into the genetic make-up of resilience in growing pigs by identifying genomic regions and candidate genes associated with resilience indicators. The findings suggest that there are novel genomic regions associated with two resilience indicators (increment BW and increment HP) in pigs, which harbour potential candidate genes involved in immune response and growth pathways, highlighting the strong relationship between resilience and immune response.
