Dynamics of feed, calcium and phosphorus intake in laying hens

These databases provide data on feed, calcium (Ca), and phosphorus (P) intake dynamics in laying hens. Since particle size is a key factor influencing nutrient utilization in laying hens, databases also include information on diet particle size, as well as Ca and P concentrations in different diet fractions. The complete methodology of data analysis is described in the paper of Hervo et al. (2025) submitted to Animal Open Space: Dynamics of feed, calcium, and phosphorus intake in laying hens. Raw data were collected during the experimental trial of Hervo et al. (2023) published in Poultry Science (102(5): 102613; https://doi.org/10.1016/j.psj.2023.102613).
