The goal of WP2 is to provide phenotypic information on local breeds, both in routine and in challenging conditions (temperature and feed resource).

The objectives of WP2 are:

• Propose and validate a locally applicable methodology (including protocols to evaluate responses to challenge) and durable data (to further re-use and share).
• Identify and organize existing data (literature, previous works) to characterize lifetime trajectories of local breeds in terms of phenotypic time-series (e.g. BW) and life history traits (e.g. age at first reproduction, lifespan)
• Contribute to the development of animal models (WP4) representative of local Mediterranean breeds, combined with the biological mechanisms studied in WP1.
• Collecting the individual data at animal level in parallel with the data collected at the farming system and herd levels in WP3 (in particular environmental fluctuations) to interpret potential trade-offs observed in phenotypic data.
