Body reserves dynamic of suckling ewes across successive production cycles under outdoor and indoor contrasting farming system conditions.

Body reserves (BR) mobilization (BRM) and accretion (BRA) are crucial biological processes in ruminants that help them manage negative energy balance and adapt to changing environments. The BR dynamics (BRD) is affected by the interplay of key factors such as the farming system (FS) characteristics, physiological stage (PhySt), and parity (Par) or cohort (Coh) of the ewes, as well as litter size (LSi) at lambing and during suckling. This study aimed to evaluate the effects of contrasting FS (intensive, indoor (IND) vs.
