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...

Comparative epidemiology of scrapie outbreaks in individual sheep flocks.

Data recording the course of scrapie outbreaks in 4 sheep flocks (2 in Cheviot sheep and 2 in Suffolks) are compared. For each outbreak the data on scrapie incidence and sheep demography and pedigrees cover periods of years or decades. A key finding is that the incidence of clinical cases peaks in sheep 2-3 years old, despite very different forces-of-infection. This is consistent with age-speci...
