CALLEJAS-JUAREZ, Nicolás; REBOLLAR-REBOLLAR, Samuel; ORTEGA-GUTIERREZ, Juan Ángel  e  DOMINGUEZ-VIVEROS, Joel. Bio-economic parameters of intensive production of beef in Mexico. Rev. mex. de cienc. pecuarias [online]. 2017, vol.8, n.2, pp.129-138. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v8i2.4415.

The objective of this research was to evaluate the productivity of beef in confinement in Mexico, through criteria of efficiency, effectiveness, quality and economy, in five entities (Nuevo Leon, Tamaulipas, Coahuila, Sonora and Baja California); considering five scales of production (3,000, 5,000, 6,000, 7,000 and 7,500 bovines completed per cycle). The average initial live weight was 267.00 ± 35.99 kg and 470 ± 11.73 kg. The average production cycle was 136 ± 22 d and 2.67 ± 0.34 cycles per year. Efficiency was 7.84 ± 1.39 kg feed/kg and 61.20 ± 0.84 % of carcass yield, efficiency 99.55 ± 0.26 %, 100 % quality and economy 3.36 ± 1.89 $/kg of net income. The benefit-cost ratio was 1.08 ± 0.03, with a marginal investment average of 17,815.98 ± 4,795.81 Mexican pesos per bovine. The conclusion is that the economic activity presents an average productivity of 63.50 ± 15.20 %.
