This study aims to evaluate the effects of tea of copaíba extract (Copaifera luetzelburgii), in differentconcentrations, added to the Tris-egg yolk extender, the functionality of the plasma membrane sperm ofcryopreserved goats. Were used four goats breeds, adults, male, six of each breed, aged between 1 and 6 years,a pool of ejaculates were formed to analyze. The animals were randomly divided into four experimentaltreatments: TI without adding of tea of copaíba extract (control); TII, added 0,1 mg of tea of copaíba extract;TIII, 0,2 mg; and TIV, 0,5 mg. The samples were frozen and stored, after 30 days were thawed for analysis byhisposmotic test (HOST). Adding tea of copaíba extract showed no significant difference between treatments forHOST, so the use of tea of copaíba extract the seminal dilution was not effective in preserving the functionalityplasma membrane sperm of goats post-thawing.(AU)
