Avaliação Da Integridade De Membrana Em Espermatozóide Bovino Criopreservado Para Prever O Índice De Prenhez

Abstract: O sêmen de doze tourinhos da raça Tabapuã, que se apresentou após a criopreservação dentro dos padrões andrológicos estabelecidos pelo CBRA (1998), foi submetido aos testes de termorresistência rápida e lenta, hiposmótico, reação acrossômica induzida pela heparina, teste da viabilidade espermática pelo azul de tripan pós-congelação e pósincubação com a heparina e índice de prenhez na primeira inseminação artificial de novilhas Nelore. As médias das variáveis contínuas dos testes mencionados foram comparadas pe… Show more

“…These findings differ from those of Dimitropoulos (1967), Amann (1989) and Farrell et al (1998), who reported a positive correlation between sperm motility and fertility in a given semen sample. However, the negative correlations observed here corroborate the findings of Emerick et al (2011), who reported a correlation of -0.22 between sperm motility and fertility rate soon after thawing. Furthermore, the negative correlations observed corroborate the findings of Vianna et al (2009), who a reported a PR between 65% and 75% in semen samples that showed 0% sperm motility in TT.…”

“…RTT and STT3 were used because they are the standard tests (Dimitropoulos, 1967). STT1 and STT2 were used as intermediate STT3 incubation times, chosen as alternative combinations (60min/38 o C and 180min/38ºC) because they were not described in the available literature, although some authors (Arruda et al, 1992;Siqueira et al, 2007;Emerick et al, 2011;Sellem et al, 2015) have worked with times and temperatures different from those of standard TTs.…”
