"Feed efficiency is an important economic and environmental parameter in raising swine. It captures how effectively livestock feed is turned into food products for humans. Increasing a pig’s feed efficiency can reduce a farm’s costs and energy use. A new study shows that one factor that could affect pigs’ feed efficiency is their gut microbiome. Feed intake and body weight measurements showed significant differences in feed efficiency among three pig breeds: Duroc, Landrace, and Large White, while genetic analyses of their gut microbiomes revealed differences in their microbial makeup. Association analyses between these datasets indicated a positive association between 4 types of bacteria and feed efficiency. This link could help both scientists and farmers understand how intestinal microbes influence animal traits crucial to production. such as those related to fatness. And it could offer a valuable new way to influence the feed efficiency of pigs..."

"Antimicrobial resistance is a critical threat to human and animal health. Animal production systems, with their often-heavy use of antibiotics, are a major driver of antibiotic resistance globally. The resistome is the collection of antibiotic resistance genes in a population of bacteria and is a window into the accumulation of antibiotic resistance in a system. A recent study compared the resistomes of an industrialized intensive pig farming system and a traditional extensive farming system. The extensive systems have lower animal densities, outdoor housing, older age at slaughter, and – critically – less antibiotic use compared to the intensive systems. Researchers examined the metagenomes of the pigs’ intestinal microbiomes, the environment on the farm, and the slurry of pig waste. Compared with extensive farms, intensive farms had a higher abundance of antibiotic resistance genes. The class of antibiotics used correlated with the category of resistance genes observed..."

"In mammals, the maternal microbiome influences both mother and infant health and can be used to predict the likelihood of preterm birth. The mother’s number of previous pregnancies, or parity, can also affect preterm birth risk, but whether parity influences the maternal or infant microbiome is unclear. A recent study used marker gene sequencing and metagenomics analyses of stool samples to investigate the microbiomes of pregnant pigs of different parities and their offspring. Microbiome “maturity index” and Dirichlet multinomial mixtures (DMM) model analyses indicated that the sow microbiome changed in predictable ways throughout pregnancy and that the changes occurred more rapidly in sows with higher numbers of previous pregnancies. Parity (high vs. zero) was linked to the levels of specific types of bacteria in the maternal gut at the end of pregnancy. Sow parity also affected the abundances of certain metabolism-related bacteria in the piglet gut 10 days after birth..."

"How do you fix a broken heart? According to a new study, TREEs can help—that is, tissue regeneration enhancer elements. The study found that these short DNA control modules from zebrafish can precisely regulate gene expression in mammals to promote healing after a heart attack. Heart attack, or myocardial infarction, and heart failure are common and devastating cardiac conditions. But the hearts of adult mammals can’t regenerate well after injury, making treatment difficult. One option is to attempt to use gene therapy with viral vectors to enhance heart cell proliferation, thus improving cardiac regeneration. However, current gene therapies are limited in their ability to control their cargoes, leading to strong, continuous delivery in one or more organs. And unchecked cell proliferation can lead to problems like tumor formation, making methods for precise control essential. Zebrafish TREEs are promising mediators of such precise control..."

"The gut microbiota is a diverse ecosystem. While bacteria are present in the greatest numbers, other microorganisms such as fungi and protists are also present, influencing many physiological functions. Analyses of the gut microbiome in livestock species have increased recently with improvements in technology and decreased cost. However, little is known about host genetic control over gut microbial communities. A recent study examined this relationship using healthy Duroc pigs. Using genome-wide association studies, researchers identified a gene regulatory network comprising 3,561 genes and 738,913 connections. Within this complex and polygenic network, five main regulators stood out. The proteins were associated with immune cell development, cell signaling in immune cells, and the vaccine response and a large number of predicted targets were genes associated with microbiota in pigs, mice, and humans. Host genetic variants associated with microbial functions were also identified..."
