“…It is also very important to note that sperm motility parameters initially decreased at 30 min incubation and then maintained another 90 min of incubation in LP in comparison to others extenders. The incubation of sperm is believed to cause an increase in sperm metabolism, thus leading to a more rapid utilization constituent present in the extender, resulting in an energy deficit (Vianna et al, 2009). Thus, LP seems better in terms of utilization of nutrients during incubation resulting higher value of sperm kinetics and motility parameters.…”

“…According to Verstegen et al (2002), the temperature indicated for the analysis of animal semen is 38°C, which is very close to the normal body temperature. High temperatures and/or long periods of incubation during TT negatively affects bovine sperm motility (Vianna et al, 2009).…”

“…Several publications have associated the motility of semen in vitro with field fertility, but there are divergences in the results. Dimitropoulos (1967), Amann (1989) and Farrell et al (1998) found a positive correlation between motility and field fertility; whereas Arruda et al (1992)., Zhang et al (1999), Graham and Mocé (2005), Vianna et al (2009), Emerick et al (2011), Nagy et al (2015 and Sellem et al (2015) found no correlation between motility and field fertility.…”

Bovine semen thermoresistance tests and their correlation with pregnancy rates after fixed-time artificial insemination  [Testes de termoresistência do sêmen bovino e sua correlação com taxas de prenhez após inseminação artificial em tempo fixo] ABSTRACTThe objective of the study was to determine whether or not there is a correlation between thermoresistance tests (TT) after semen thawing and pregnancy rate (PR) after fixed-time artificial insemination (FTAI). Four different TT were performed on ten samples used for AI; a rapid test (RTT) (30min / 46°C) and three slow tests (STT): STT1 (60min/38°C), STT2 (180min/38°C), and STT3 (300min/38°C). Two hundred and fifteen multiparous crossbred cows were submitted to FTAI under the following protocol: on day zero (d0) the animals received a P4 device +EB; on d7 PGF 2α ; on d8 P4 was removed and eCG+EC were administered; IATF was performed on d10. Three gestational diagnoses (G D) were performed on d40, d70 and d120. The mean sperm motility (%) in RTT and STTs were 19.84±6.13, 28.55±10.48, 17.62±5.87 and 8.63±3.46, respectively, and TP in the three DG 61.86%, 57.67%, and 55.81%, respectively. Through Person test a significant negative correlation (P< 0.05) was found between STT2 and PR at 60 days (r= -0.644) and between STT3 and all TPs (r= -0.774, -0.752, 0.748). It was concluded that TT parameters are not able to determine correlation between semen quality and TP.

Avaliação de diferentes osmolaridades de soluções hiposmóticas e tempos de incubação no teste hiposmótico do sêmen de touros Nelore

RESUMO IntroduçãoO teste hiposmótico avalia a atividade bioquímica da membrana plasmática intacta, devido ao influxo de água para o interior das células. Vários autores têm observado em sêmen in natura e congelado/descongelado que a integridade funcional da membrana plasmática avaliada pelo teste hiposmótico é uma importante ferramenta complementar para predizer a capacidade de fertilização do sêmen de bovinos (Bacinoglu et al., 2008). No entanto, não se entende completamente os resultados obtidos no teste hiposmótico, como também não existe padronização do protocolo para a realização da técnica em relação ao tempo de incubação e à osmolaridade da solução para sêmen de bovinos.
