Data underlying the publication: "Effects of hatching system on chick quality, welfare and health of young breeder flock offspring"

<p>The aim of the current study was to evaluate effects of two alternative hatching systems (hatchery-feeding and on-farm hatching)<br> compared to conventional hatching systems with respect to chick quality, welfare and health of a young breeder flock.<br> To study the effect of treatments on the competence of the humoral immune response, blood titres after a live attenuated NCD<br> vaccination was assessed.<br> To study differences in disease resilience, the susceptibility to develop tracheal inflammation after infection with a<br> life attenuated infectious bronchitis vaccine virus was assessed by trachea lesion scoring and expression of genes related<br> to epithelial integrity and inflammatory responses.</p>
