GONZALEZ, Jorge; KLEE, Germán y OLAVE, José. Economic evaluation of beef cattle production systems with Hereford cattle in the Andean foothills of the VIII Region. Agric. Téc. [online]. 2004, vol.64, n.2, pp. 182-191. ISSN 0365-2807. http://dx.doi.org/10.4067/S0365-28072004000200007.
Three beef cattle production systems were economically evaluated for the Andean foothills based on subterraneum clover (Trifolium subterraneum) and hay supplementation during winter (TS); subterraneum clover with winter supplementation of hay and oats (TC); and subterraneum clover in a mix with crimson clover (Trifolium incarnatum), and subterraneum clover with festuca (Festuca arundinaceae) and alfalfa (Medicago sativa) plus winter supplementation with red clover (Trifolium pratense) hay and oats (Avena sativa) grain (VE). Young Hereford bull calves were used, with an initial 197 kg LW and 6.3 months of age, going out from system at 14 to 16 months of age with 385 kg LW. The systems were projected to three pasture dimensions of 25, 50 and 200 ha. The cost structure considered variable (CV) and fixed costs (CF). The prices used corresponded to April 2001. Profitability without fixed costs varied between 17.1% in system TS to 23.4% in system VE. On including CF, profitability decreased in all systems with values that fluctuated between 1.2 and 18.5%, in systems TS and VE, respectively. Profitability of the systems according to farm sizes fluctuated between - 0.1% in the system TS/25 ha farm, and 19.7% in the combined system VE/200 ha. A greater influence of CF was present in the profitability of smaller size farms. The VE system always had positive profitability in relation to calf purchase price, young bull sale price, feeding costs and calf mortality percentage.
