Understanding the seasonality of performance resilience to climate volatility in Mediterranean dairy sheep
Abstract As future climate challenges become increasingly evident, enhancing performance resilience of farm animals may contribute to mitigation against adverse weather and seasonal variation, and underpin livestock farming sustainability. In the present study, we develop novel seasonal resilience p...
