Adição do látex de mangabeira (Hancornia speciosa) ao diluidor citrato-glicose-gema na motilidade do sêmen ovino resfriado por 24h: estudos preliminares / Addition of mangabeira latex (Hancornia speciosa) to citrate-glucose-egg yolk extender on motility of ram semen cooled for 24 hours: preliminary studies

ABSTRACT

This study aimed to evaluate the effect of different concentrations of mangabeira latex (Hancorniaspeciosa) added to ram semen extender on motility of cooled semen stored for 24 hours. The latex was added tocitrate-glucose-yolk extender in concentrations of 0% (control), 2%, 4% and 6% (vv) and diluted with SantaInês ram semen and cooled to 4°C for 24h. The semen was evaluated for sperm motility and vigor. No statisticaldifferences were found for fresh semen and the treatments with the addition of latex. These results indicate thatno improvement in ram semen quality cooled and stored for 24 by the addition of mangabeira latex.(AU)
