Objective. To evaluate the economic viability of a continuous supplementary feeding scheme (CSFS) in local goats from the end of gestation and during lactation in a region of Coahuila State, in northern Mexico. Materials and methods. Twenty-four local goats were utilized: control group (CG, n=12) and supplemented group (SG; n=12). In both groups daily milk production (DMP), per lactation (TMPL), and per lactation stage [early (MPEL) middle (MPML), and late lactation (MPLL)], duration of lactation (DL, days), final live weight (FLW), and final body condition (FBC) were recorded; and in kids birth weight (BW), weight at sale (WS), age at sale (AS), and mortality rate (MR). An economic analysis was performed according to the methodology of the American Agricultural Economics Association. Costs of daily supplementation, labor for the handling and care of the animals, and prices from sale of milk and kids were considered, as well as the Internal Rate of Return (IRR). Results. The best productive performance and highest incomes were for SG (p<0.05) for all variables, except AS and MR. The highest values in CG (p<0.05) were for AS and economic profit for all variables, except in MPEL and IRR for TMPL. There were positive profits for SG in MPEL and MPML, and negative in MPLL for SG, but with higher FBC. Conclusions. The CSFS is economically viable to increase income and profits from kids and milk sales and, in addition, improves the FBC of the dams.
