VILABOA-ARRONIZ, Julio et al. Livestocks  systems  with  tropical  dairy creolle (Reyna) in Costa Rica. Agron. Mesoam [online]. 2012, vol.23, n.1, pp.167-178. ISSN 2215-3608.

The aim of this study was to identify the technology components used in livestock systems with Tropical  Dairy  Creole  (CLT)  Reyna  and  socioeconomic characteristics of farmers who use this race. The study was conducted  in  the  provinces  of  Cartago  and  Guanacaste, Costa Rica in May-July 2011. We interviewed managers of dairy modules at Experiment Station  Alfredo Volio Mata (EEAVM) at the University of Costa Rica and the Tropical Agricultural  Research  and  Education  (CATIE)  plus  five independent   producers. Variables analyzed were social, technological and commercial awareness as well as the use of this breed. The data was analyzed by descriptive statistics and cluster analysis using SAS version 8.0. There were four groups  called  G1:  Guanacaste  producers,  G2:  EEAVM, G3:  Cartago  producer  and  G4:  CATIE.  The  surface  for these  groups was 60±31.6, 24, 57 and 46 hectares with a united animal per hectare (AU ha-1) 0.6±0.1, 2.6,  0.7 and 4.1,  respectively. Race Reyna is mainly used to  establish Bos taurus and/or Bos indicus crosses in  order to obtain adaptability and resistance to the environment. However, its use and management has been undermined by institutional policies, both legal and productive.
