Popis: Lamb production systems can be adjusted base on the particular characteristics of each farm and available forages. This study aimed to compare plasma calcium concentrations in post parturient ewes in different production systems. Blood samples were collected 24 hours postpartum to determine calcium concentrations. Additionally, the length of the second and third stages of labor were assessed. Plasma calcium concentrations differed between productions systems with ewe managed under the semi-intensive system (sINT) having mean calcium concentrations of 9.43 ± 0.16 mg/dl compared to 7.64 ± 0.16 mg/dl (P < 0.05) for those managed under the extensive (EXT). Maternal diet during pregnancy affected lamb weight with lambs from the sINT group, weighing 5.58 ± 0.18 kg compared to 3.97 ± 0.26 kg in the EXT group. Fetal weight appeared to influenced the length of the second stage of labor, which differed between the systems (P
