"Animal health is of utmost importance in the production of milk, meat, and other animal products. Although vitamin supplements can help ensure livestock remain as healthy as possible, they are often expensive, driving up the cost of production. To help reduce these costs, a team of researchers set out to better understand how the essential vitamins B and K₂ are produced by microbes in the gastrointestinal tracts of ruminants, which are animals with complex digestive tracts composed of multiple distinct compartments to help them break down their plant-based diets. The team used genetic data from previous studies to identify 1,135,807 genes and 2366 full genomes involved in B or K₂ vitamin biosynthesis in the gastrointestinal tracts of seven ruminant species. They also found that most of this biosynthesis took place in the stomach compartments rather than other regions and that a high-grain diet enhanced most vitamin biosynthesis but inhibited cobalamin synthesis..."

"Probiotics are one strategy farmers use to boost animal production. These live microorganisms promote gut health, improve metabolism, and stave off harmful pathogens. While the effects of probiotics on the gut microbiomes of terrestrial animals have been extensively examined. less is known about their effects on the microbiomes of fish. To find out, researchers looked at multiple omics datasets, to explore how rainbow trout responded to feed containing probiotics and “synbiotics," mixtures of pre- and probiotics. A look at conventional measures of feed efficiency showed mixed results versus controls, such as decreases in weight gain (not significant) and protein efficiency (significant), but a significant increase in lipid efficiency. In the gut, pro- and synbiotic additives were associated with a decreased abundance of otherwise plentiful Mycoplasma bacteria..."
