Gastrointestinal nematode infections represent a problem for the health of cattle, as well as affecting the economics of farmers and producing industries. The necessary conditions for the development of the eggs of the nematodes, contained in the feces of the bovine, were simulated using a coproculture in sawdust of laurel (Laurus nobilis). In this investigation it was tried to evaluate differences in the recovery time of nematode larvae from the coproculture. In the methodology, the flotation technique was used to identify nematode eggs and the McMaster to count the amount of eggs per gram of feces and the amount of larvae recovered from the coproculture at different times. The analysis of the results was performed with the Minitab software version 19, and an ANOVA was applied with a post hoc analysis of Tukey. It was established that exist a significant difference in the nematode count when they are collected at 3 hours.
