Agriculture's Environmental Impact Reduced If Cows are Supplemented With RbST

Cows that receive recombinant Bovine Somatotropin (rbST) make more milk, thus easing natural resource pressure and also reducing environmental impact, a new study has said.

Researchers at University Of Cornell carried out the study.

Human Growth Hormone (HGH) - Preview
Human growth hormone, otherwise known as somatotropin, stimulates growth, cell reproduction, and bone regeneration.

Producing milk uses large quantities of land, energy and feed, but rbST, the first biotech product used on American farms, has been in agricultural use for nearly 15 years.

Now, it is found to reduce the carbon hoofprint by easing energy, land and nutritional inputs necessary to sustain milk production at levels sufficient to meet demand.

This research found that, compared to a non-supplemented population, giving rbST to one million cows would enable the same amount of milk to be produced using 157,000 fewer cows.

Acromegaly - Causes Symptoms Complications Diagnosis Treatment Prognosis
Acromegaly (Greek-enlargements of the extremities) is a hormonal disorder resulting from excessive production of the growth hormone by the pituitary gland after puberty, often referred as gigantism.

The nutrient savings would be 491,000 metric tons of corn, 158,000 metric tons of soybeans, and total feedstuffs would be reduced by 2,300,000 metric tons.

Producers could reduce cropland use by 219,000 hectares and reduce 2.3 million tons of soil erosion annually.

Scientists Identify Potential Protein Biomarkers for Growth Hormone
Researchers at Ohio University have identified several proteins in mice that might act as biomarkers for growth hormone.

According to the study, for every one million cows supplemented with rbST, the world would see an environmental saving of 824 million kilograms of carbon dioxide, 41 million kilograms of methane and 96,000 kilograms of nitrous oxide.

For every one million cows supplemented with rbST, the reduction in the carbon footprint is equivalent to removing approximately 400,000 family cars from the road or planting 300 million trees.

Athlete's Mind Determines Effect of Performance Enhancing Drugs
When athletes think they're using a performance-enhancing drug, their performance tends to get better - even if they're taking a dummy drug.

"Supplementing cows with rbST on an industry-wide scale would improve sustainability and reduce the dairy industry's contribution to water acidification, algal growth, and global warming," said Judith L. Capper, Cornell post-doctoral researcher.

According to Dale E. Bauman, Cornell professor of animal science, "This study demonstrates that use of rbST markedly improves the efficiency of milk production, mitigates environmental impact including greenhouse gas emissions and reduces natural resource requirements such as fossil fuel, water and land use."
