Abstract

To determine the prevalence rate of bovine brucellosis disease in cattle farms of small and medium producers of Arenillas canton in the province of El Oro, Arenillas, Palmales, La Cuca, Carcabon and Chacras parishes were considered. For the diagnosis of the disease, blood samples were extracted from the coccygeal vein of 380 bovines, with a 5cc syringe and then deposited in a red cap tube that was placed at an incline to accelerate the collection of serum. For the processing, 35 l of the serum sample and 35 l of the antigen were taken to place them in the agglutinoscope and proceed to mix them with the help of a toothpick making light soft circular movements to finally after 2 or 4 minutes perform the reading of the test. The study variables of the investigation were the following: Taking the first variable as a reference, the highest percentage of animals sampled was obtained in the Palmales parish, which represented 58.95%, followed by the Cuca parish, which represented 17.89%, the Arenillas parish with 60 animals, which represented 15.79%, the Carcabón parish, the Carcabón parish with 60 animals, and the Carcabón parish, which represented 15.79%, In relation to the breed variable, the most common was the mestizo, which represented 67.11%, the Brahman represented 27.89%, and other breeds such as the Holstein represented 2.63%, the Gyr and Jersey represented 0.79%, the Brown Swiss represented 0.53% and the Brown Swiss represented 0.53%, In the age group category, animals from 1 to 2 years old represented 25.53%, animals from 2 to 3 years old represented 23.42% and animals from 3 years old represented 51.05%, in relation to the sex variable, the most significant group was the females which represented 90, 79%, while males represented 9.21%, in relation to the variable type of farm, the dairy farm animals represented 24.47%, the meat farm type represented 64.47%, and finally the mixed farm type represented 11.05%. It is concluded that the prevalence rate in Arenillas Canton is 0.53%, considering that vaccination should be implemented in the different cattle farms, because this disease is still in force and there is a danger of dissemination and affectation to humans and animals.
