Abstract: | It has been proposed that the metabolic energy requirements of free-ranging hens are up to 15% higher compared to caged hens due to the increased metabolic activity required for locomotion and thermoregulation (GfE 1999; Tiller 2001; Aerni et al. 2005). The aim of the study was to investigate the impact of various feed strategies on laying performance and egg quality of free-range laying hens. A total of 9,375 hens, placed amongst 5 flocks of 40,000 hens each were selected according to their range usage (hens accessed the range at least 70% of available days at 18-22 weeks of age). | Publication Type: | Conference Publication | Conference Details: | APSS 2021: 32nd Annual Australian Poultry Science Symposium, Online Event, 9th - 10th February, 2021 | Source of Publication: | Proceedings of the Australian Poultry Science Symposium, v.32, p. 179-179 | Publisher: | University of Sydney | Place of Publication: | Sydney, Australia | ISSN: | 1034-6260 1034-3466 |
