Avaliação do chá do extrato de copaíba (Copaifera luetzelburgii) pós-criopreservação de sêmen de caprinos pelo teste de termoresistência / Evaluation of the tea of copaíba extract (Copaifera luetzelburgii) in goat semen post-thawing by term-resistance test

ABSTRACT

The semen cryopreservation process causes damages in spermatozoa characteristics. This study aimedto evaluate the effects of tea of Copaíba extract (Copaifera luetzelburgii), in different concentrations, added tothe Tris-egg yolk extender, in the quality of post-cryopreserved spermatozoa from locally adapted breeds ofgoats. Were used four (4) goats Breeds (Azul, Canindé, Moxotó e Repartido) adults, male, six of each breed,aged between 1 and 6 years, a pool of ejaculates were formed to analyze. The animals were randomly dividedinto four experimental treatments TI (Control), TII (0,1mg), TIII (0,2mg) and TIV (0,5mg). The samples werefrozen and stored, after 30 days they were thawed for analysis by term-resistance test (TTR). The addition of teaof copaíba extract showed no significant difference between treatments by TTR, therefore the use of tea copaíbaextract in seminal diluting not increment the sperm longevity post-thawing.(AU)
