Abstract

This study aims to evaluate the physicochemical characteristics, fat composition, and sensory attributes of lamb meat produced in two feeding systems: (1) Unweaned and unsupplemented lambs in the pasture and (2) early weaned lambs in the pasture with concentrate supplementation post-weaning. The experiment was performed in the winter–spring pastures in the subtropical region of Brazil. The experimental design was completely randomized with two treatments (feeding systems), four paddocks per treatment and twenty lambs (experimental units) per paddock. Carcass weight, dressing percentage, pH, rib eye area, subcutaneous fat thickness, and visual fatness were determined. Loin samples were used for instrumental color, thawing and cooking loss, shear force, water holding capacity, fat and sensory analyses. Carcass pH did not differ between the systems (p > 0.05). Supplemented weaned lambs showed a higher body condition score, carcass weight, dressing percentage and fatness (p
