Fig. 5From: Pattern and repeatability of ascarid-specific antigen excretion through chicken faeces, and the diagnostic accuracy of coproantigen measurements as compared with McMaster egg counts and plasma and egg yolk antibody measurements in laying hensWorm burden of laying hens experimentally infected with both Ascaridia galli (a) and Heterakis gallinarum (b), and the number of eggs per gram of faeces (EPG) (c) across different weeks post-infection (n = 108). Figures are LS means with their standard errors. The EPG was determined by wpi 4. Thus, the number of faecal samples for EPG was n = 90Back to article page
