| Abstract |
Free-range laying production system supplies 52% of the national egg demand (Australian Eggs 2021). Hens in this production system show a broad spectrum of behaviours. Some hens spent 77-80% of their time on the outdoor range while stayer hens spent less than 20% of their time on the outdoor range (Sibanda et al. 2020a). It is still unclear if the differences in range use, which is associated with egg production, is the cause or consequence of a diverse phenotypic and intestinal microbiota composition. Very little is known about the intestinal microbiota of free-range laying hens to date. A better understanding of the microbiota composition may help to establish better management strategies. Therefore, the aim of this study was to describe the intestinal microbiota of commercial free-range laying hens with divergent body weight and range use. |
