Exploring the Possible Link between the Gut Microbiome and Fat Deposition in Pigs

Guangmin Zhao et al.

Summary: This study discovered a link between the gut microbiome, lipogenic properties, and oxidative stress in pigs. High-fat pigs had an abundance of Archaeal species with methanogenesis functions, leading to more-efficient fat deposition, while low-fat pigs had higher abundances of butyrate-producing bacteria species that alleviated fat deposition.

Gut Bacterial Composition and Functional Potential of Tibetan Pigs Under Semi-Grazing

Hui Niu et al.

Summary: This study provides a preliminary understanding of the gut bacterial composition of Tibetan pigs. The results reveal that the bacterial community in Tibetan pigs is more complex compared to other pig breeds. The dominant bacteria in Tibetan pigs are more correlated with functions regulating the host's immune and inflammatory responses. Additionally, the taxonomic relationships of gut bacteria in Tibetan pigs vary at different developmental stages. Gender also plays a role in the composition and function of bacterial inhabitants in the gut.

Metagenomic and Transcriptomic Analyses Reveal the Differences and Associations Between the Gut Microbiome and Muscular Genes in Angus and Chinese Simmental Cattle

Ya Zheng et al.

Summary: The gut microbiome and heredity are important factors affecting the intramuscular fat of cattle. This study analyzed the gut microbiome and intramuscular differentially expressed genes (DEGs) in Angus and Chinese Simmental cattle to decipher these differences. The results showed that Angus had higher diversity in gut microbiome and higher abundance of certain bacteria compared to Chinese Simmental. DEGs upregulated in Chinese Simmental were mainly associated with immune and inflammatory responses, while those in Angus were related to muscle system and myofibril regulation.

Dietary Administration of L-Carnitine During the Fattening Period of Early Feed Restricted Lambs Modifies Ruminal Fermentation but Does Not Improve Feed Efficiency

Alba Martin et al.

Summary: This study found that adding L-Carnitine to the diet during the fattening period of lambs fed with restricted feed can improve ruminal fermentation parameters, modulate gut microbiota, and enhance the health of the animals. However, the effects of L-Carnitine on feed efficiency were not significant, possibly due to the improved ruminal fermentation and increased intramuscular fat accumulation caused by L-Carnitine supplementation.

Microbiability of meat quality and carcass composition traits in swine

Piush Khanal et al.

Summary: The impact of gut microbiome composition on meat quality and carcass composition traits of pigs varied over different production stages, with a more prominent contribution observed for carcass composition traits. Microbiability estimates were greater for carcass composition traits than meat quality traits, showing high microbial correlations among traits related to fat deposition. Better understanding of microbial composition could aid the improvement of complex traits in swine, particularly carcass composition traits.

The changing microbiome of poultry meat; from farm to fridge

M. Marmion et al.

Summary: Chickens harbor a diverse community of microorganisms, influenced by factors such as diet, genetics, and immune system activity, as well as external influences like weather and exposure to other animals. Bacteria such as Campylobacter and Salmonella play important roles in the quality and safety of poultry products, with steps like washing and chilling in the production cycle aiming to control their proliferation. Predictions suggest that poultry meat, particularly chicken, will become the most consumed meat globally in the next decade, highlighting the importance of understanding and controlling the development of microbial communities on birds.

Summary: Recent studies have established connections between animal health and performance, and the host's microbiota. The microbial responses in poultry to changes in housing conditions and the host's environment are still not well understood. This study found that the microbiota composition of adult poultry flocks remains stable following sudden environmental changes, with unique fluctuations over time observed in each flock. The access to an outdoor range had no detectable effect on microbial community composition, but differences were found in the richness and variability of the microbiota among chickens in the same flock.
