Faecal egg count distributions over time. Faecal egg counts between May and October and at post-mortem counts (PM), black bars. The grey shaded area shows the lower 95 % of the distribution of faecal egg counts over each month. Maximum likelihood estimates of dispersion parameters for the raw faecal egg count data for each month separately and estimated standard errors are given above each bar. Smaller values indicate more dispersed data
