- Weaning and concentrate supplementation on the characteristics of carcass cuts and longissimus muscle of Suffolk lambs finished on pasture Sergio Rodrigo Fernandes Alda Lúcia Gomes Monteiro Marina Gabriela Berchiol da Silva Cláudio José Araújo da Silva Júlia Marina Zanotelli Paulo Rossi Pedro Henrique Nicolau Pinto Agrociencias leg muscularity Creep feeding fat thickness loin eye area The aim of this study was to evaluate the influence of weaning and concentrate supplementation on the characteristics of carcass cuts and longissimus muscle of Suffolk lambs finished on a Tifton 85 (Cynodon spp.) pasture. Weaning and concentrate supplementation strategies were evaluated in four finishing systems: i) non-weaned and non-supplemented lambs; ii) non-weaned lambs supplemented with concentrate in creep feeding; iii) weaned and non-supplemented lambs; and iv) weaned lambs supplemented with concentrate. In the systems with weaning, lambs were weaned at 46 ± 6 days of age. In the systems with supplementation, the concentrate was offered daily at 2% of lambs’ body weight. Weaning led to a decrease, whereas supplementation led to an increase in carcass cut weights. Supplemented lambs had lower yields of neck and uncovered ribs, and higher yields of breast + flank and loin. The characteristics of loin eye and fat thickness over the longissimus muscle presented lower values in weaned lambs and higher values in supplemented lambs. Keeping lambs with their dams and offering concentrate supplementation until slaughter are strategies recommended to obtain heavier cuts with increased muscularity and fat content. 2022 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303171455022 https://www.redalyc.org/journal/3031/303171455022/ https://www.redalyc.org/journal/3031/303171455022/html/ https://www.redalyc.org/journal/3031/303171455022/303171455022.epub https://www.redalyc.org/journal/3031/303171455022/movil 10.4025/actascianimsci.v44i1.53445 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
