Unusual feed supplement could ease greenhouse gassy cows

2010-09-07
(Press-News.org) Cow belches, a major source of greenhouse gases, could be decreased by an unusual feed supplement developed by a Penn State dairy scientist.

In a series of laboratory experiments and a live animal test, an oregano-based supplement not only decreased methane emissions in dairy cows by 40 percent, but also improved milk production, according to Alexander Hristov, an associate professor of dairy nutrition.

The natural methane-reduction supplement could lead to a cleaner environment and more productive dairy operations.

"Cattle are actually a major producer of methane gas and methane is a significant greenhouse gas," Hristov said. "In fact, worldwide, livestock emits 37 percent of anthropogenic methane."

Anthropegenic methane is methane produced by human activities, such as agriculture.

Compared to carbon dioxide, methane has 23 times the potential to create global warming, Hristov said. The Environmental Protection Agency bases the global warming potential of methane on the gas's absorption of infrared radiation, the spectral location of its absorbing wavelengths and the length of time methane remains in the atmosphere.

Methane production is a natural part of the digestive process of cows and other ruminants, such as bison, sheep and goats. When the cow digests food, bacteria in the rumen, the largest of the four-chambered stomach, break the material down intro nutrients in a fermentation process. Two of the byproducts of this fermentation are carbon dioxide and methane.

"Any cut in the methane emissions would be beneficial," Hristov said.

Experiments revealed another benefit of the gas-reducing supplement. It increased daily milk production by nearly three pounds of milk for each cow during the trials. The researcher anticipated the higher milk productivity from the herd.

"Since methane production is an energy loss for the animal, this isn't really a surprise," Hristov said. "If you decrease energy loss, the cows can use that energy for other processes, such as making milk."

Hristov said that finding a natural solution for methane reduction in cattle has taken him approximately six years. Natural methane reduction measures are preferable to current treatments, such as feed antibiotics.

Hristov first screened hundreds of essential oils, plants and various compounds in the laboratory before arriving at oregano as a possible solution. During the experiments, oregano consistently reduced methane without demonstrating any negative effects.

Following the laboratory experiments, Hristov conducted an experiment to study the effects of oregano on lactating cows at Penn State's dairy barns. He is currently conducting follow-up animal trials to verify the early findings and to further isolate specific compounds involved in the suppression of methane.

Hristov said that some compounds that are found in oregano, including carvacrol, geraniol and thymol, seem to play a more significant role in methane suppression.

Identifying the active compounds is important because pure compounds are easier to produce commercially and more economical for farmers to use.

"If the follow-up trials are successful, we will keep trying to identify the active compounds in oregano to produce purer products," said Hristov.

Hristov has filed a provisional patent for this work.

Researchers at UC Riverside find solution to cell death problem vexing stem cell research
2010-09-07
RIVERSIDE, Calif. – Human pluripotent stem (hPS) cells can generate any given cell type in the adult human body, which is why they are of interest to stem cell scientists working on finding therapies for spinal cord injuries, Parkinson's disease, burns, heart disease, diabetes, arthritis, and other ailments. Before hPS cell technologies can be translated into clinical applications, however, some obstacles must first be overcome. One such obstacle frustrating stem cell researchers is "cell death" that the major types of hPS cells, including human embryonic stem cells ...

Plant nutrients from wastewater

2010-09-07
Plants cannot thrive without nutrients such as nitrogen, phosphorous or potassium, therefore farmers usually use organic and industrially manufactured mineral fertilizers to supply wheat, maize and others with these vital substances. In future, the need for nutrients will be soaring because we will only be able to supply the world's growing population with food and cover surging demands for biofuels by using fertilizers. Logically, that causes the prices for these nutrients to skyrocket. But that is not the only problem. The deposits of rock phosphates required for manufacturing ...

Choice of career is a major risk factor for persistent neurodermatitis

2010-09-07
A child who can't stop scratching himself may well be suffering from atopic dermatitis, also known as neurodermatitis. Extreme irritability of the skin with a concomitant urge to scratch is typical of the disorder. The condition often appears during the first year of life and is on the increase in industrialized countries. The patient's skin becomes hypersensitive and reacts strongly to even mild irritation. A research team led by Dr. Astrid Peters and Professor Katja Radon from Ludwig-Maximilians-Universitaet (LMU) in Munich has just published a longitudinal study which ...

Nearly 1% of the population is affected by rheumatoid arthritis, and women are affected three to five times more often then men. Although the course of disease varies greatly, daily living activities are impaired in most affected ...

COLUMBIA, Mo. – With the fragmentation and globalization of the U.S. textile and apparel industry, business activities and roles have changed, impacting their organizational identity. The evolving organizational identity of these firms has created many questions as to how it affects the businesses financially. Now, a researcher at MU has explored how U.S. textile and apparel firms describe themselves as organizations and how those descriptions compare to U.S. Census Bureau industry classifications.Jung Ha-Brookshire, an assistant professor in the Textile and Apparel Management ...

1. A Low-carb Diet Based on Animal Protein May Increase Death Risk Evidence shows that a low-carbohydrate diet produces weight loss and improves some cardiovascular risk factors. However, health effects of a low-carbohydrate diet may depend on the type of protein and fat consumed. Researchers followed 85,168 women and 44,548 men on a low-carbohydrate diet for 26 and 20 years respectively. The patients ate either an animal-based (emphasizing animal sources of fat and protein) low-carbohydrate diet, or a vegetable-based low-carbohydrate diet. The researchers found that ...

ST. PAUL, Minn. –A new study shows that mild cognitive impairment (MCI) may affect more men than women. The research is published in the September 7, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology. Mild cognitive impairment is a condition in which people have problems with memory or thinking beyond that explained by the normal rate of aging. The study found that MCI was 1.5 times higher in men compared to women. MCI often leads to Alzheimer's disease. "This is the first study conducted among community-dwelling persons to find ...

The study will be published in the September issue of Neurology. "The finding that the frequency of mild cognitive impairment is greater in men was unexpected, since the frequency of Alzheimer's disease is actually greater in women. ...

Interrupting death messages to treat bone disease

A surface molecule on bacteria that instructs bone cells to die could be the target for new treatments for bone disease, says a scientist speaking at the Society for General Microbiology's autumn meeting today. Blocking the death signal from bacteria could be a way of treating painful bone infections that are resistant to antibiotics, such as those caused by Meticillin-resistant Staphylococcus aureus (MRSA). Bone disease, or osteomyelitis, affects 1 in 5,000 people around the world. It can occur at any stage in life and attack any bone in the body, where it leads to ...
