摘要: Abstract The movement distances of merino sheep were monitored over a 24 h period using global positioning system tracking collars and correlated with their faecal egg counts. A linear relationship between the logarithm count mean distance moved per time step was found. results suggest that animal behaviour productivity outcomes might be influenced even at low levels. considerable variability observations about this model suggests it useful for identifying those animals inherently resistant to internal parasites. Such technology could used as part breeding program aimed improving stock resistance
