    The general objective of this present research project was to analyze the selection index of the sustainable genetic improvement program for dairy cattle in the parish of Mulliquindil, located in the canton of Salcedo, province of Cotopaxi, through genetic and non-genetic traits. The research was conducted with a total of 45 evaluated cattle and 8 producers who participated in the project. Data collection took place during the months of October, November, and December of 2023, covering aspects such as production costs, daily weight gain (DWG), 305-day milk production, and milk density. Using analysis tools, the following results were concluded: a sale price of $0.38 per liter, with a production cost of $0.12, generating a profit of $0.26. It was observed that the highest cost was related to feeding, with limited reliability due to the lack of records by the producers, which may lead to an underestimation of production costs. Regarding the genetic values (EBV) of the animals, the daily weight gain showed a phenotypic average of 337.90 g/day, while the genetic value of the 10 selected animals was 63.05 grams per day. As for milk production, an average genetic value of 2531.56 liters per lactation was obtained. Additionally, in terms of density, an average of 1.030 g/ml was recorded. Although milk production is reasonable, areas requiring improvement were identified in terms of weight gain and density. It is recommended to establish a genetic improvement program and conduct follow-up to optimize future results.
