Abstract

Recombinant bovine somatotropin (rbST) is a proteohormone, which can be used to increase milk production in dairy cows. While its use in food production is approved in several countries, such as the United States (US), it is banned in the European Union (EU). Therefore, appropriate monitoring...

Abstract

The emission of greenhouse gases (GHG) is a major cause of global warming, being a worldwide concern in recent decades. Carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are the main greenhouse gases and ruminants are one of the major contributors to the production of these gases around...
