The 7,800-page milestone includes two production-animal topics — Dairy goat milking stress addresses the welfare implications of intensification: machine milking stress, kid separation distress, housing density, and the particular vulnerability of high-yield breeds like Saanen and Alpine — European sea bass (Dicentrarchus labrax) crowding impacts covers a major aquaculture species: stocking density effects on fin erosion, cortisol levels, growth suppression, and disease susceptibility — these topics extend the hub's agricultural welfare coverage from terrestrial livestock into aquaculture, recognizing that fish welfare is an emerging frontier in animal ethics
