The use of natural resources is an important topic to optimize the efficiency of cattle production . The purpose of this work is to describe the project of the Bruna d'Andorra; a local cow breed under an extensive cow-calf system in Andorra (Europe), as an example of local farming and marketing of its meat products in an area with adverse environmental conditions . This breed is located in Andorra, a microstate that consists predominantly of rugged mountains and harsh weather conditions . The cow-calf Bruna d'Andorra extensive system is thoroughly described and productive and reproductive performance, compiled over 21 years (2000-2020), has been analyzed by years with the Chi-square test or ANOVA to compare proportions or means, respectively, and regression analysis was used to decipher evolution across years . The results show a population with a census large and stable enough to avoid inbreeding . Moreover, a sustained improvement of the productive performance and maternal fitness has been observed along the studied period for Bruna d'Andorra . The work concludes that local breeds can achieve sustainable animal production, especially when farmers, public administration and commercial circuits in the area agree to cooperate on such projects . The study also concludes that the Bruna d'Andorra cow breed can still improve in meat and reproductive performance.
