A new study found that high doses of red seaweed reduce methane emissions in cows, but the effect is short-lived. The researchers discovered that the seaweed inhibits methanogenic microbes, leading to a near-total elimination of a key microbe involved in methane formation.
A new study reveals that humans are losing important cellulose-degrading microbes in their gut microbiome, especially in industrial societies. The loss of these microbes is linked to a shift away from fiber-rich diets, which are essential for maintaining a balanced intestinal flora.
An international team of scientists is recruiting microbes to reduce methane production in cows, with the goal of reducing greenhouse gas emissions. The project involves tracking hydrogen production and utilization during fermentation to redirect excess hydrogens towards more productive end-products.
Researchers discovered a microbial culture from baby kangaroo feces that can inhibit methane production in cow stomach simulators, replacing it with beneficial acetic acid. This innovation has the potential to mitigate greenhouse gas emissions and improve cow health.
Researchers at UTIA are studying feed efficiency in pregnant Angus heifers to improve the overall sustainability of beef production. The team is examining the impact of pregnancy on rumen environment and nutritional changes, aiming to provide producers with strategies to improve feed efficiency and calf quality.
Researchers discovered that bacteria from cow stomachs can digest certain types of plastic, including PET, PBAT, and PEF. The study found that the microorganisms can break down these plastics more effectively than single microorganisms, representing a promising eco-friendly approach to reduce plastic litter.
Research reveals that women entrepreneurs who identify as mumpreneurs prioritize traditional masculine behaviors over feminine traits, sacrificing personal time for business growth. This hybrid approach perpetuates existing power structures in the business world, devaluing those who choose to spend time with their families.
New research from the University of Illinois shows that consistent energy levels and rumen-boosting supplement monensin are ideal during the dry period for dairy cows. The study found no significant difference in cow performance or metabolic indicators between controlled-energy diets and variable energy diets.
Researchers investigate how genetics influence rumen microbiome in cattle, seeking to identify host genomic markers for heritability. The study aims to manipulate microbiomes to enhance agricultural production and develop more sustainable cow-calf systems.
Researchers found that clay can improve the degradability of feedstuffs in lactating cows, reducing aflatoxin and subacute ruminal acidosis symptoms. Clay was added to six different feedstuffs at varying percentages, showing improved digestibility and fat utilization.
A study by Jean-Michel Hatt and his team reveals that the stomach's rinsing system effectively removes abrasive particles, including dust and sand, from ruminant food. This mechanism helps prevent excessive tooth wear and allows animals to thrive in dusty environments.
The study presents a reference catalog of rumen microbial genomes and isolates, targeting economically and environmentally relevant microbes. The collection contains nearly 33,000 degradative Carbohydrate-Active Enzymes that can break down plant cell walls.
A DNA study of cow stomachs could significantly boost meat and dairy production by understanding which microbes help cattle extract energy from food. The research identified previously unknown enzymes that can break down plant material, potentially leading to new biofuels.
A study published in the Journal of Animal Science found that wheat can be used as an alternative energy source for beef cattle, with optimal feeding levels determined to be above 50%, and increasing monensin supplementation improving feed efficiency, while proper grain processing is necessary.
A study published in the Proceedings of the National Academy of Sciences found that human gut microbes can digest fiber and ferment it into nutrients for human cells. The microbes appear to have enzymes that break down complex plant fiber components more efficiently than cow rumen microbes, which could aid in biofuels production.
A recent study published in Science has sequenced the sheep genome, providing new insights into ruminant evolution and lipid metabolism. The researchers found a previously unrecognized gene LCE7A associated with wool formation and identified key genes involved in keratinized epidermal structure development.
A study published in Science reveals nearly 30,000 novel enzymes that can efficiently degrade plant cell wall materials, a major breakthrough for large-scale biofuel production. The discovery sheds light on the molecular machinery used by microbes in the cow's rumen to break down biomass into simple sugars.
Scientists have identified 27,755 potential enzyme genes and found 57% to be active against cellulosic plant material. The bovine rumen is a promising habitat for finding plant-degrading enzymes for second-generation biofuels.
Researchers at the University of Illinois have discovered how a cow rumen bacterium breaks down hemicellulose into simple sugars, with implications for human health, nutrition, and biofuel production. The study provides an enzyme cocktail that can release simple sugars from plant cell walls, advancing the biofuels industry.
Researchers at UT Southwestern Medical Center have identified a genetic sensing mechanism that allows E. coli to form colonies in cattle, and found that interfering with this system can prevent the bacteria from colonizing and reaching humans. This discovery could lead to new strategies for preventing food-borne illnesses.
A new study by Northwestern University suggests that individuals with abundant moral self-worth may engage in immoral behavior to balance out their perceived level of goodness, while those who experience a moral-cleansing effect tend to engage in good work to restore their ideal level of moral self-worth.
Researchers at Ohio State University have developed a new microbial fuel cell that harnesses the power of cow waste to generate electricity. The small cell can produce about three times the power as its predecessor and is a quarter of its size, making it a promising alternative energy source.
Scientists have discovered a way to create electricity from cow waste by harnessing the power of microorganisms that break down cellulose. This process uses rumen fluid and cow dung to generate electricity, offering a promising alternative to traditional energy sources.
