Resumo: | In this study, we aimed to evaluate the rate of bovine embryo production by using 50 ng/mL melatonin supplementation in in vitro culture medium. For this, oocytes from slaughterhouse ovaries were matured in vitro in TCM-199 medium with Earle’s balanced salt solution + 10% SFB, FSH, and LH in an atmosphere of 5% CO2. Twenty-four hours after IVM, the oocytes underwent in vitro fertilization in human tubal fluid under the same conditions as above, for 18 h. Semen was fractionated by Percoll gradient centrifugation and the concentration of sperm was adjusted to 1 × 106/mL. Probable zygotes were then divided into two groups: the control group grown in drops of 90 μL SOFaa medium + 0.6% BSA + 2.5% SFB, in an atmosphere of 5% CO2, 90% N2, and a melatonin group (Mel), similarly cultured in 90 μL drops of SOFaa medium + 0.6% BSA + 2.5% SFB + 50 ng/mL melatonin. Cleavage rates were assessed on day 3 (D3). On D7, blastocyst formation rates were evaluated. Eight routines were performed (320 oocytes per routine). Data were analyzed with ANOVA, followed by Tukey’s range test using a general linear model. The level of statistical significance was set at 5%. There were no differences in the rates of cleavage or blastocyst formation between the control and melatonin groups (P > 0.05). Thus, under the conditions used in this study, supplementation with melatonin did not yield benefits in increasing the rate of in vitro bovine embryo production. |

Para ello, se maduraron in vitro ovocitos de ovarios de matadero en medio TCM-199 con solución salina equilibrada de Earle + SFB, FSH y LH al 10% en una atmósfera de CO2 al 5%. Veinticuatro horas después de la MIV, los ovocitos se sometieron a fertilización in vitro en líquido tubárico humano en las mismas condiciones que antes, durante 18 h. El semen se fraccionó mediante centrifugación en gradiente de Percoll y la concentración de espermatozoides se ajustó a 1 x 106 / ml. Luego, los cigotos probables se dividieron en dos grupos: el grupo de control crecido en gotas de 90 μL de medio SOFaa + 0.6% BSA + 2.5% SFB, en una atmósfera de 5% CO2, 90% N2 y un grupo de melatonina (Mel), de manera similar cultivado en gotas de 90 μL de medio SOFaa + BSA al 0,6% + SFB al 2,5% + 50 ng / mL de melatonina. Las tasas de escisión se evaluaron el día 3 (D3). En D7, se evaluaron las tasas de formación de blastocistos. Se realizaron ocho rutinas (320 ovocitos por rutina). Los datos se analizaron con ANOVA, seguido de la prueba de rango de Tukey utilizando un modelo lineal general. El nivel de significación estadística se estableció en 5%. No hubo diferencias en las tasas de escisión o formación de blastocistos entre los grupos de control y melatonina (P> 0,05). Por lo tanto, en las condiciones utilizadas en este estudio, la suplementación con melatonina no produjo beneficios en el aumento de la tasa de producción de embriones bovinos in vitro.Neste estudo, objetivou-se avaliar a taxa de produção de embriões bovinos utilizando suplementação de melatonina 50 ng/mL em meio de cultivo in vitro. Para isso, oócitos de ovários de abatedouro foram maturados in vitro em meio TCM-199 com solução salina balanceada de Earle + 10% SFB, FSH e LH em uma atmosfera de 5% de CO2. Vinte e quatro horas após a MIV, os oócitos foram submetidos à fertilização in vitro em fluido tubárico humano nas mesmas condições acima, por 18 horas. O sêmen foi fracionado por centrifugação em gradiente de Percoll e a concentração espermática ajustada para 1 × 106/mL. Os prováveis zigotos foram então divididos em dois grupos: o grupo controle cultivado em gotas de 90 μL de meio SOFaa + 0,6% de BSA + 2,5% de SFB, em uma atmosfera de 5% de CO2, 90% de N2, e um grupo de melatonina (Mel), da mesma forma cultivadas em gotas de 90 μL de meio SOFaa + 0,6% BSA + 2,5% SFB + 50 ng / mL de melatonina. As taxas de clivagem foram avaliadas no dia 3 (D3). No D7, as taxas de formação de blastocisto foram avaliadas. Oito rotinas foram realizadas (320 oócitos por rotina). Os dados foram analisados por ANOVA, seguido pelo teste de intervalo de Tukey usando um modelo linear geral. O nível de significância estatística foi estabelecido em 5%. Não houve diferenças nas taxas de clivagem ou formação de blastocisto entre os grupos controle e melatonina (P > 0,05).
