Economic values were estimated for meat sheep raised in a pasture based production system in semi-arid Brazil using data on the Morada Nova hair sheep breed. The traits considered were lambing percentage (LP), litter size (LS), lamb mortality (LM), yearling mortality (YM), ewe and ram mortality (AM), female slaughter weight (FSW), male slaughter weight (MSW), ewe adult weight (EAW), ram adult weight (RW), carcass yield (CY), number of lambings per year (NLY), age at first lambing (AFL) and number of anthelminthic doses used per year (AC). The economic values were estimated using the profit equation (profit=revenue−costs) after a one unit and 1% increase of each trait, keeping all other traits at their mean value. With a 1% increase in the traits, the economic values (US$ per ewe per year) for LP, LM, MSW, CY and NLY were 0.781, −0.138, 0.416, 0.827 and 0.781, respectively. The production system with …
