Raw Data for Article: Circular valorization of acid silage from invasive Pterygoplichthys spp. in hens' diets: impacts on laying performance and egg quality

This dataset contains experimental data collected over a 90-day period under a continuous repeated-measures design. The study was conducted to evaluate productive, physiological, and/or performance-related responses under controlled conditions, allowing the assessment of temporal dynamics and treatment effects. The dataset includes repeated observations from the same experimental units across time, enabling longitudinal analysis. Variables may include production indicators, physiological measurements, and experimental factors such as treatment group, time points, and replication structure. The design allows for the evaluation of both within-subject and between-treatment variability. Data are organized in tabular format, with each row representing an individual observation at a specific time point, and columns corresponding to measured variables and identifiers (e.g., animal ID, treatment, period, or replicate). The structure supports statistical approaches such as repeated measures analysis, mixed models, and time-series evaluation. This dataset is suitable for researchers interested in animal production, physiology, experimental design, and applied statistical modeling. It can be used for validation studies, methodological development, or meta-analytical purposes.
