Estimated values of Eimeria oocysts per gram faeces (OPG) over time in lambs infected with Eimeria spp. (D0–D2), treated with spruce bark extract (IB) or treated with water (IC). The bark extract was given D0–D11. Area between dashed lines: 95% confidence interval. The figure shows data transformed with the natural logarithm (ln)
