Optimisation of Protein Nutrition in Laying Hens Via Determining the Limiting Amino Acid Order in Reduced Protein Diets and AM/PM Feeding

Abstract

These datasets were collected during the experiment at UNE Laureldale Poultry Research Cage Facility (ARA21-096) to identify the order of limiting amino acids in a wheat-sorghum-based diet for laying hens. These data are sorted into the following groups: <br><br> Chapter 3:<br> Data on hen weight, laying performance and egg quality, nutrient digestibility, serum uric acid, tibia bone health, and caecal microbiota were collected. All these data belong to the Thesis Chapter 3: The Order of Limiting Amino Acids in a Wheat–Sorghum-Based Reduced-Protein Diet for Laying Hens. This chapter has been published in Applied Sciences (MDPI): https://doi.org/10.3390/ app132312934.

Chapter 4: <br> Data on hen and egg weight uniformity, laying performance and egg quality, and nutrient digestibility were collected. All these data belong to the Thesis Chapter 4: Effects of AM/PM Diets on Laying Performance, Egg Quality, and Nutrient Utilisation in Free-Range Laying Hens. This chapter has been published in Applied Sciences (MDPI): https://doi.org/10.3390/app14052163 <br><br>

Chapter 5:<br> Data on home pen behavioural observation, individual hen ranging behaviour using RFID, welfare and external health parameters assessments including tonic immobility, novel object test, and stress hormones (feacal glucocorticoids metabolites), bone health, and welfare Indicators of free-range laying hens were collected. All these data belong to the Thesis Chapter 5: Effects of AM/PM Feeding on Behaviour, Range Use and Welfare Indicators of Free-Range Laying Hens. This chapter has been submitted in Animal Production Science for publication (under review).
