The mean numbers of batches of sheep received by (or sent from) a farm in a year was in the range 6.7 to 7.8 over the 4 years (Table 2B).
To make the analyses relevant to diseases with different animal-level prevalence on affected farms the directed contact rate from farm j to farm i in a particular year, aij, was defined in three ways: 1) present or absent (unweighted), 2) weighted by the number of batches of sheep moved (batch-weighted), and 3) weighted by the total number of sheep moved (animal-weighted).
SAMS collates records of movements of batches of sheep, pigs and goats in Scotland.
The Animal Movements Licensing System AMLSS) in England and Wales has recorded all movements of batches of sheep and other animals, including movements from Scotland, since 2001, being kept as a digital database (AMLS2) since 2005.
The batches of sheep were transported from Glen Innes to the University of New England, Armidale, where they were shorn before being housed in individual pens and adapted over a 2-week period to a 50/50 mix of lucerne and oaten chaff (Manuka Feeds Pty Ltd ,Quirindi, NSW, Australia; 88.5% DM; 167 g CP/kg DM, 8.7 MJ ME/kg DM) fed at 20 g/kg LW as a single meal at 0800 h each day.
And there's a lot of sheep.
Beginning in 2007, we also found that some batches of commercial sheep blood contained Candidatus B. melophagi DNA.
Over a period of 12 days, methane emissions were recorded in the field by testing batches of 15 sheep in individual portable accumulation chambers (PAC; Goopy et al., 2011) for 1 h at 0900, 1030, 1200, 1330 and 1500 h (a total of 75 sheep/day).
Specifically, the UK government has attempted to increase reporting of cattle movements by electronic means, and has introduced schemes to collect details on batch movements (rather than individual-level data) of sheep, pigs, and goats [ 25].
