CUEVAS REYES, Venancio et al. Analysis of the milk production function in dual purpose bovine system in Ahome, Sinaloa. Rev. mex. de cienc. pecuarias [online]. 2018, vol.9, n.2, pp.376-386. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v9i2.4545.

The objective was to estimate a production function that describes the relationship between production and milk production factors in the dual purpose bovine system in the municipality of Ahome, Sinaloa. With information from 74 production units a Cobb Douglas production function was estimated. The model obtained was $\mathrm{Y}=0.7819X_2^{0.0095}{X}_3^{0.0699}{X}_4^{0.5323}$. Of the three variables analyzed, only the agricultural area and the number of adult cows were significant (P<0.05). The coefficient of determination obtained was 55.03 %. The use of the agricultural area, as well as the number of adult cows present a low marginal productivity, so that milk production shows decreasing returns to scale. It is concluded that under the current combination and use of resources, the production of bovine milk in northern Sinaloa is inefficient and the total product is below the potential that could be obtained with improvements and use of technology in food and genetic improvement of livestock.
