Resumo: | The objective of this study was to evaluate the addition of antioxidants in different cryopreservation diluents on bovine semen quality after thawing and the in vitro production of embryos. First, the effects of adding different concentrations of glutathione (1.5 and 2.5 mM) and melatonin (0.5 and 1.0 mM) in egg yolk semen cryopreservation diluents (Bovimix®) and soy lecithin (Andromed®) were evaluated. The results showed that the addition of the antioxidant glutathione did not improve the maintenance of sperm characteristics of bovine semen. Melatonin had a negative effect on the spermatic parameters evaluated. The diluent Andromed® obtained better parameters of spermatic kinetics when compared with the diluent Bovimix®. However, in relation to the membrane integrity analyzes of the Bovimix® diluent showed better performance in the maintenance of these parameters. The effect of the cryopreservation diluents and the addition of glutathione in the vitro production of bovine embryos (PIVE) was then evaluated. The rate of cleavage, blastocyst rate and hatching were evaluated eight and nine days after IVF, as well as the correlation between sperm characteristics and PIVE. The diluent Andromed® provided a better cleavage rate, with no effect of the addition of glutathione in it. However, the addition of 2.5 mM glutathione in the Bovimix® diluent improved the cleavage rate. There was a significant correlation of high and low magnitude between some sperm characteristics with the rate of cleavage. It was concluded that glutathione did not improve sperm viability. Melatonin worsened the maintenance of sperm characteristics. Andromed® diluent was more efficient in the in vitro production of bovine embryos with no glutathione effect observed in this diluent. The addition of 2.5 mM glutathione in the egg yolk Bovimix® diluent gave a higher cleavage rate. In vitro evaluation of semen quality is not the best method to predict the fertilizer potential of the same in PIVE, because only significant low to moderate magnitude correlations were observed between some parameters of semen quality and fertilization rate. |

Primeiramente, avaliou-se os efeitos da adição de diferentes concentrações de glutationa (1,5 e 2,5 mM) e melatonina (0,5 e 1,0 mM) em diluentes de criopreservação de sêmen à base de gema de ovo (Bovimix®) e lecitina de soja (Andromed®). Os resultados demonstraram que a adição do antioxidante glutationa não melhorou a manutenção das características espermáticas do sêmen bovino. A melatonina reduziu a qualidade das características espermáticas avaliadas. O diluente Andromed® obteve melhores variáveis de cinética espermática quando comparado com o diluente Bovimix®. No entanto, com relação às análises de integridade de membrana o diluente Bovimix® demonstrou melhor desempenho na manutenção dessas variáveis. Posteriormente, avaliou-se o efeito dos diluentes de criopreservação e a adição de glutationa sobre a produção in vitro de embriões bovinos (PIVE). Avaliou-se a taxa de clivagem, taxa de blastocisto e eclosão oito e nove dias após a fertilização (FIV), assim como a correlação entre as características espermáticas e as taxas de desenvolvimento embrionário. O diluente Andromed® proporcionou melhor taxa de clivagem, sem a necessidade da adição de glutationa no mesmo. Entretanto, a adição de 2,5 mM de glutationa no diluente Bovimix® melhorou a taxa de clivagem. Houve correlação significativa de alta e baixa magnitude entre algumas características espermáticas com a taxa de clivagem. Conclui-se que a glutationa não melhorou a viabilidade espermática. A melatonina reduziu a manutenção das características espermáticas. O diluente Andromed® foi mais eficiente na produção in vitro de embriões bovinos não sendo observado efeito da glutationa neste diluente. A adição de glutationa na concentração de 2,5 mM no diluente Bovimix®, à base de gema de ovo, proporcionou maior taxa de clivagem. A avaliação in vitro da qualidade do sêmen não é o melhor método para predizer o potencial fertilizante do mesmo na PIVE, pois só foram observadas correlações significativas de baixa a moderada magnitude entre algumas características de qualidade do sêmen e a taxa de fertilização.Submitted by JÚLIO HEBER SILVA (julioheber@yahoo.com.br) on 2017-12-13T18:53:37Z No. of bitstreams: 2 Tese - Natalia do Carmo Silva - 2017.pdf: 2078936 bytes, checksum: a9911e8e1a6da63e31e4fb86a1dbf785 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-12-14T10:19:33Z (GMT) No. of bitstreams: 2 Tese - Natalia do Carmo Silva - 2017.pdf: 2078936 bytes, checksum: a9911e8e1a6da63e31e4fb86a1dbf785 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-12-14T10:19:33Z (GMT).

Melatonin had a negative effect on the spermatic parameters evaluated. The diluent Andromed® obtained better parameters of spermatic kinetics when compared with the diluent Bovimix®. However, in relation to the membrane integrity analyzes of the Bovimix® diluent showed better performance in the maintenance of these parameters.
