Estimation of the Carbon Footprint in Dairy Sheep Farm
By 2050, the earth’s population is expected to be more than 9 billion. The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an in...
متن کاملEfficiency of Dairy Production and its Carbon Footprint
The productivity of the American farmer has increased dramatically over the last century. One hundred years ago a farmer produced enough to feed 15 people and over 40% of the US population was involved in agriculture-related businesses. Today the produce from an average farmer feeds 130 people and farmers represent less than 2% of the U.S. population. The increases in agricultural productivity ...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Variation in carbon footprint of milk due to management differences between Swedish dairy farms.
To identify mitigation options to reduce greenhouse gas (GHG) emissions from milk production (i.e. the carbon footprint (CF) of milk), this study examined the variation in GHG emissions among dairy farms using data from previous CF studies on Swedish milk. Variations between farms in these production data, which were found to have a strong influence on milk CF, were obtained from existing datab...
متن کاملRole of dairy in the carbon footprint of US beef.
In PNAS, Eshel et al. (1) present a novel methodology for calculating a suite of ecological impacts from livestock and poultry production in the United States. The authors acknowledge two complementary and valuable approaches in ecological accounting: bottom up and top down. Top-down analyses, however, are only valuable insofar as they adequately represent the structure of the study system. By ...
