More fat, less protein improves canine olfactory abilities

From sniffing out bombs and weapons to uncovering criminal evidence, dogs can help save lives and keep the peace. Now, researchers have uncovered how to improve dogs’ smelling skills through diet, by cutting protein and adding fats. Such a diet, say the researchers, appears to help dogs return to lower body temperatures after exercise, which […]

Feeding corn germ to pigs does not affect growth performance

Inclusion of corn germ in swine diets can reduce diet costs, depending on the local cost of corn germ and other ingredients. Recent research conducted at the University of Illinois indicates that corn germ can be included at up to 30 percent in diets fed to growing pigs. “In previous research, we had seen that […]

What do American bullfrogs eat when they’re away from home? Practically everything

Posted on

American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems. In the largest study of its kind to date, the stomach contents of […]

Cows fed flaxseed produce more nutritious dairy products

Dairy cows that are fed flaxseed produce more nutritious milk, according to a new study by Oregon State University. Their milk contained more omega-3 fatty acids and less saturated fat, the study found. Diets high in saturated fat can increase cholesterol and cause heart disease, while those rich in omega-3 and other polyunsaturated fatty acids […]

Drought in the Horn of Africa delays migrating birds

The catastrophic drought last year in the Horn of Africa affected millions of people but also caused the extremely late arrival into northern Europe of several migratory songbird species, a study published December 6 in Science shows. Details of the migration route was revealed by data collected from small backpacks fitted on birds showing that […]

Dogs’ natural feeding intake is high in fat

An international team of researchers has shed new light on the natural feeding behavior of domestic dogs and demonstrated that they will naturally seek a daily dietary intake that is high in fat.

Raw food not enough to feed big brains

Eating a raw food diet is a recipe for disaster if you’re trying to boost your species’ brainpower. That’s because humans would have to spend more than 9 hours a day eating to get enough energy from unprocessed raw food alone to support our large brains, according to a new study that calculates the energetic […]

Rat study sparks genetically modified food furore

Tumours developed more readily in rats fed genetically modified maize than in controls, recent research reports. Europe has never been particularly fond of genetically modified (GM) foods, but a startling research paper published last week looks set to harden public and political opposition even further, despite a torrent of scepticism from scientists about the work.

Meeting pigs’ phosphorous requirements with fermented soybean meal

Fermented soybean meal (FSBM), considered a promising substitute for fish meal in weanling pig diets because of its protein content, lower cost, and lack of anti-nutritional factors, may have an additional advantage. University of Illinois researchers recently found that pigs digest the phosphorus in FSBM better than the phosphorus in conventional soybean meal. Most of […]

Hungry monkeys not living longer

Slash your food intake and you can live dramatically longer—at least if you’re a mouse or a nematode. But a major study designed to determine whether this regimen, known as caloric restriction, works in primates suggests that it improves monkeys’ health but doesn’t extend their lives. That outcome contradicts a similar study of monkeys reported […]

Fish and rice flourish together in paddies

A traditional farming technique that cultivates rice and fish side-by-side could help small farmers earn more money from their crops and reduce the impact on the environment, according to a study. When fish were introduced into flooded paddy fields, farmers were able to grow the same amount of grain as in conventional rice monocultures — […]

Feeding cows natural plant extracts can reduce dairy farm odors and feed costs

With citizens’ groups seeking government regulation of foul-smelling ammonia emissions from large dairy farms, scientists report that adding natural plant extracts to cow feed can reduce levels of the gas by one-third while reducing the need to fortify cow feed with expensive protein supplements. They reported in Denver at the 242nd National Meeting & Exposition […]

Chillingham cattle cowed by climate change

Posted on

The team of ecologists lead by Dr Sarah Burthe of the Centre for Ecology & Hydrology were able to use the cattle to discover more about the impact of climate change on phenology in mammals because – encouraged by Charles Darwin – information about the cattle has been collected since 1860. According to Dr Burthe: […]

Methane gas from cows: The proof is in the feces

Posted on

Scientists could have a revolutionary new way of measuring how much of the potent greenhouse gas methane is produced by cows and other ruminants, thanks to a surprising discovery in their poo. Researchers from the University of Bristol and the Teagasc Animal and Grassland Research Centre in Ireland, have found a link between methane production […]

In the U.S., even zoo gorillas need to switch to a heart-healthy diet. “A lot are dying of heart disease, we believe like humans,” said Elena Hoellein Less, a PhD candidate in biology at Case Western Reserve University. In fact, heart disease is the number one killer of male Western lowland gorillas — the only […]

Key nutrient found to prevent cataracts in salmon

The role of a key nutrient which prevents cataracts in salmon has been revealed by eye specialists at the University of East Anglia. Research published September 30 in the American Journal of Physiology — Regulatory, Integrative and Comparative Physiology shows how the nutrient histidine, when added to the diet of farmed salmon, stops cataracts (clouding […]

Veterinarian says natural foods not always best for pets

While natural food is a rising trend among humans, pet owners should be careful before feeding similar types of food to their pets, according to a Kansas State University veterinarian. All too often pet owners assume that because certain foods, such as fruits and vegetables, are healthy for them, they are also healthy for their […]

New insights could mean better fish feeds

A better understanding of what happens in a fish’s body when it eats could lead to the production of better fish feeds. Researchers at the University of Gothenburg, Sweden, are hoping to contribute to more energy-efficient aquaculture. In the long term, this could increase the supply of farmed fish and so provide more food for […]

Hops helps reduce ammonia produced by cattle

An Agricultural Research Service (ARS ) scientist may have found a way to cut the amount of ammonia produced by cattle. To do it, he’s using a key ingredient of the brewer’s art: hops. Cattle, deer, sheep, goats and other ruminant animals depend on a slew of naturally occurring bacteria to aid digestion of grass […]

A new study identifies cattle feed as a possible culprit in the long-standing mystery of why California’s San Joaquin Valley — a moderately-populated agricultural region — has higher levels of ozone (one of the main ingredients in smog) than many densely-populated cities. The report, which explains how fermented cattle feed works with automotive exhausts in […]

Intestinal health in salmon fed a plant-based diet

Access to marine raw materials for fish feed production is limited. Any future increase in the numbers of farmed salmon will therefore necessitate an increased use of feeds of plant origin. If salmon are to grow satisfactorily and remain healthy, it is important to obtain knowledge of just how plant-based feed affects the health of […]

Genetically modified root systems result in plants that survive with little water

A part of the global food crisis is the inefficiency of current irrigation methods. More irrigated water evaporates than reaches the roots of crops, amounting to an enormous waste of water and energy.
