Economic evaluation of a long-term supplementation feeding scheme in grazing local goats

Evaluación económica de un esquema de alimentación complementaria continua en cabras locales en pastoreo

Objective. To evaluate the economic viability of incorporating a long term-supplementary feeding scheme in grazing local goats from the last third of gestation and throughout lactation. Materials and methods. Twenty-four local goats were utilized: control group (CG, n=12) and supplemented group (SG; n=12). Daily milk production (DMP) was recorded in goats, per lactation (MPLT), 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). In kids, birth weight (BW), weight at sale (WS), age at sale (AS), and mortality rate were recorded. The economic analysis considered the costs of daily supplementation, labor for handling and care of the animals, and sale prices of milk and kids. Results. The best productive behavior and the highest incomes were obtained in SG (p<0.05) for all variables, except AS and mortality rate. The highest values in CG (p<0.05) were obtained in AS and economic profit in almost all the considered variables, Except in MPEL. Positive profits were obtained in SG in early and middle lactation, and negative in late lactation for SG, but with higher FBC. Conclusions. A long-term supplementary feeding is economically viable to increase income and profits from kids and milk sales and improves the body condition of the dams, which will benefit the productivity of the herd.
