Determination of the technical and economic optimum in piglet production under a semi-technified system: Economical optimums in piglets

Resumen

Objective: To estimate the optimal technical and economic levels for semi-technified piglet production based on the number of farrowings.

Design/Methodology/Approach: A linear additive statistical model was applied to the parameters, while a nonlinear cubic model was employed for the variables, using field data collected in 2023 from a semi-technified farm located in Temascaltepec, State of Mexico. The dependent variable was the number of piglets, and the independent variable was the number of farrowings.

Results: At the technical optimum, the number of farrowings was 2.54, corresponding to a maximum piglet production of 10.4749 and a net cash gain of $2,974.9. At the economic optimum, the number of farrowings was 2.43, equivalent to a production of 10.4731 piglets and a net cash gain of $3,298.1.

Limitations/Implications: In this type of analysis, the technical optimum is closely aligned with the economic optimum. Findings/Conclusions: The point of maximum piglet production at weaning did not necessarily correspond to the point of maximum net cash gain at sale.
