Resumo
Parasitic diseases associated with cattle are responsible for losses in beef and dairy livestock. Among those diseases eimeriosis stands out, whose agents are protozoans from the phylum Apicomplexa, class Coccidia and genus Eimeria. It impacts the production systems mostly in its subclinical form, responsible for considerable reductions in the zootechnical performance of the animals. This research aimed to determinate the frequency of the parasitism of Eimeria species in different categories in the beef and dairy livestock in the state of Goiás and evaluate the efficacy of sodic lasalocid against Eimeria spp. in calves, allied to the analysis of the ponderal development of treated animals and the analysis of some epidemiological factors able to interfere in the infection. To analyze the levels of the infection, naturally infected animals were evaluated. The amount of oocysts from the parasite in fecal samples were expressed in oocyst per gram of feces (OoPG) and the species differentiation were conducted by microscope with computerized system LAS LEICA®, considering the agents phenotypical characteristics.
