VELASCO FUENMAYOR, Julia  y  ORTEGA SOTO, Leonardo. The Artificial Insemination and its Effect on Partial Productivity Index of Dual- Purpose Cattle Farms.. Rev. Cient. (Maracaibo) [online]. 2008, vol.18, n.3, pp.278-283. ISSN 0798-2259.

The objectives of this study were to identify and quantify the determinants of artificial insemination (AI) and to evaluate the effect of AI on the partial productivity indices of dual-purpose cattle farms located in Zulia State, Venezuela. A Logit model was used, resulting as the explanatory variables of the use of AI: degree education of farmer, size of farm, geographic location, and frequency of visit of producers to own farms. Regarding to partial productivity indices, the AI only had effect on animal productivity.
