Evaluación de los animales con base a lo caracteres de importancia económica en la producción de leche de bovinos acorde al objetivo de mejora genética en la parroquia de Mulalillo cantón Salcedo.

In the Mulalillo parish, the evaluation of the characters of economic importance in milk production was carried out, which were determined based on the objectives of genetic improvement. The methodology was carried out by collecting data and records, to establish selection criteria: days of breastfeeding, age at first birth and days open; and the variability of milk production characteristics: bovine weight gain, milk weight in kg, milk density, mastitis test using the California Mastitis test (CMT), in such a way that all of them are correlated and selected the suitable animals. As a result, it is obtained that the variations that occur in different traits include daily weight gain (583.16 g/day),milk production (8.68 kg/day), density (1028.36 g/ml), duration of lactation (141 days) and age at first birth (37.55 months) and business day (151 days). This allows us to conclude that productive efficiency in the Salcedo parish Mulalillo canton is efficient, as long as the parameters are within the range of values established by various authors and are based on the needs of this province. It is concluded that, while selection ranges are established in each of the criteria for the selection of the reproducers, thus giving 23 cows that fit the established characters and are considered as mothers of the reproducers for the dissemination of the genetic material ; Of course, everything is associated with the profitability of cattle production systems.
