Ychwanegu Tag | Crynodeb: | The present study was carried out in a farm located in the Nueva Esperanza Campus, belonging to the San Luis de Pambil parish, Guaranda canton, Bolívar province, at an altitude of 103 meters above sea level. The work consisted of determining the productive behavior in Brown Swiss x Creole bulls under grazing through the application of commercial anabolics. Three treatments were evaluated: T1 (Pasture), T2 (Estradiol (43.9 mg) + Pasture) and T3 (Trenbolone (100 mg) - Estradiol (14 mg) + Pasture). A completely randomized block design with two or more units per treatment (DBCA), consisting of three treatments and eight replications. The data obtained were subjected to an analysis of variance (ANOVA) and for the comparison of means the Tukey test was used (p≤ 0.05). The applied treatments did not show significant differences in the variables of initial weight, final weight and thoracic circumference; However, the animals treated with T2 (Estradiol (43.9 mg) + Grazing) showed significant differences in the other variables, which was reflected by the records obtained, mainly in Total weight gain with 84.88 kg, Average daily gain weight of 0.71 kg / day and Abdominal circumference with 168.25 cm, the same ones that proportionally influence the productive parameters of this cross. Additionally, T2 (45.73%) managed to prevail over T3 (35.52%) and the control group (37.63%) in terms of profitability, generating the highest net profit from the sale of the bulls with $ 1296.7 dollars of profit, this is summarized that the use of this treatment in the fattening of Brown Swiss x Creole bulls is viable both economically and productively.
