Local agropastoral systems are low-input based on rain-fed cereal cultivation, associated with small ruminant flocks of 20 to 150 heads, including variable proportions of sheep and goats.
The maps of proportions of sheep sampled were also used to display the locations of abattoirs used for sampling, so they were presented as regular land area based maps.
Our results provide the first data of PrP genotypes of these main landraces, both purebred and crossbred sheep, together with a small proportion of Texel sheep.
Combinations of p0 and β1 resulting in more severe initial outbreaks also produce a rapid decline in the proportion of susceptible sheep to a level that is insufficient for sustaining the disease.
This study, which comprised a large proportion of the sheep population in Norway, revealed a markedly increasing trend in stillbirth rate from 2000 through 2010.
Average proportions of goats, sheep and equines (mainly mules and a few donkeys) per family are 89% (range 71 to 100), 8% (range 0 to 29) and 3% (range 0 to 27), respectively.
Average proportion of goats and sheep per family flock are 89% and 8%, respectively, which indicates that Siahjel nomads mainly rely on goats.
