Table 2. Raw data from pilot studies carried out during feeding device optimisation, used to inform statistical model.
Three groups of four hens had the on-hen feeding device in place for three hours. Each device contained around 50 adult female mites and Assay 1 was carried out when hens were aged 18 weeks and Assay 2 when hens were aged 22 weeks. Groups 1 and 2 refer to “Control” groups of hens in vaccine trials.
