“…Returning from the grazing route (18:00 h), the goats of the supplemented group received supplementary feeding (TABLE II) separately from the rest of the herd, in order to minimize the substitution effect on consumption of forage in the grazing route [11], and until goats consumed the total amount offered. LW and BCS were measured on two occasions prior to kidding.…”

The production of goat's milk under extensive grazing is very important to ensure an adequate growth of the progeny, but the productivity of local does and their progeny is not accurately characterized, particularly in the semi–arid Region of Northern Mexico. The aim was to evaluate the productive potential performance of local does and their offspring, when does are offered a supplementary feeding program in pre and post–partum period. Twenty–four local does and their progeny (n=40) were used and divided into two groups: 1) Control group; does fed exclusively on grazing, 2) Supplemented group; does were supplemented at 1.5% of live weight 45 d before and 45 d after parturition. Differences due to treatment were found (P<0.05) for kid´s weight at sale (KWS), kid´s age at sale (KAS), kid´s daily weight gain (KDWG) and doe’s milk production (DMP). Kid’s mortality percentage and birth weight, milk fat content and doe’s live weight did not differ between treatments (P>0.05). High positive correlations between kid´s weight at birth (KWB) and KWS and KDWG were found (P<0.0001), but it was negative with KAS. On the other hand, KWS was positively correlated (P<0.05) with KDWG and DMP. Finally, KAS was negatively correlated with KDWG (P<0.0001) as well as KDWG with DMP (P<0.001) and protein content (P<0.05). Its concluded that pre and postpartum supplementation in local does helps to express the productive potential for milk production, plus protein and lactose contents at starting of lactation, which in turn enhanced the performance of their progeny.

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.
