SEVERINO LENDECHY, Víctor Hugo et al. Socioeconomic and technological characterization of criollo cattle productive systems in Campeche, México. Acta univ [online]. 2021, vol.31, e3102.  Epub 16-Fev-2022. ISSN 2007-9621.  https://doi.org/10.15174/au.2021.3102.

In order to carry out a technological characterization of the productive system with criollo cattle from Nunkini in Campeche, Mexico, 10 production units (PU) were evaluated. Their technological level (TL) was determined based on their technical-productive variables and it was classified as low (50%), medium (30%), or high (20%). Producers’ average age, education, and experience (years) was 62.3±3.2, 7.3±0.9, and 25.2±5.4, respectively (p < 0.05). The average age and weight at first estrus in females was 30.9±4.9 months and 276.5 kg±17.3 kg, respectively (p < 0.05). The average age and weight at first service was 36.9±5.7 months and 306.0 kg±28.8 kg, respectively (p < 0.05). The average of open days and calving interval was 205.0±38.1 days and 15.9±1.3 months, respectively (p < 0.05). The productive parameters varied according to the TL of the PU. This criollo breed is rustic and precocious. The Nunkini criollo cattle nucleus is in risk of extinction.
