Resumo: | The aim of this study was to evaluate parameters indicative of sperm quality of fresh and post-thawed semen of Aberdeen Angus, Holstein and Nelore bulls. Thirty-nine bulls were used: Aberdeen Angus (n=13), Holstein (n=13) and Nelore (n=13). The ejaculate collects were performed twice a week using artificial vagina, totaling 792 semen collections, 307 for Aberdeen Angus, 225 for Holstein and 260 for Nelore bulls. After collection, fresh semen was evaluated and semen freezing was performed. After freezing, the batches were thawed and progressive motility was determined. The analysis of fresh semen showed that there was no difference (P = 0.053) between the Aberdeen Angus and Nelore breeds, while ejaculates from Holstein bulls showed a statistical difference (P = 0.024). As well, a difference (P<0.001) was identified in the sperm concentration of the three breeds. In the samples evaluated after thawing, a statistical difference was observed between Holstein and Nelore breeds (P<0.001), while the values of the Angus breed were similar to the other two breeds. The difference in motility of fresh and post-thawing semen showed that Nelore and Angus bulls showed greater variation in values between the analyzes (26.0±8.9% and 25.3±8.4%, respectively) showing a significant difference (P<0.001) in relation to Holstein bulls (20.6±9.3%) that obtained the smallest difference. The analysis of fresh and post-thawing semen did not show any significant difference (P=0.13) between breeds. In conclusion, the semen cryopreservation process causes a decrease in the physical parameters of the semen and these quality losses suffer interference according to the breeds. |

Se utilizaron 39 toros: Aberdeen Angus (n = 13), Holandés (n = 13) y Nelore (n = 13). La recolección de semen se realizó por vagina artificial dos veces por semana, totalizando 792 recolecciones de semen, 307 para toros Aberdeen Angus, 225 para toros holandeses y 260 para toros Nelore. Después de la cosecha, se evaluó el semen fresco y luego se congeló. Después de la congelación, se descongelaron las dosis y se determinó la motilidad progresiva. El análisis de semen fresco mostró que no hubo diferencia (P = 0.053) entre las razas Aberdeen Angus y Nelore, mientras que los eyaculados de toros Holandés mostraron una diferencia (P = 0.024). Además, se identificó diferencia (P <0,001) en la concentración de esperma de las tres razas. En las muestras evaluadas después de la descongelación, hubo diferencia entre los toros Holandés y Nelore (P <0.001), mientras que los valores de los toros Angus fueron similares a las otras dos razas. La diferencia en la motilidad del semen fresco y post-descongelación mostró que los toros Nelore y Angus presentaron mayor variación en los valores entre los análisis (26,0 ± 8,9% y 25,3 ± 8,4%, respectivamente) mostrando una diferencia (P <0,001) en comparación a los toros holandeses (20,6 ± 9,3%) que tuvieron la menor diferencia. El análisis de semen fresco y posterior a la descongelación no mostró diferencias (P = 0,13) entre razas. En conclusión, el proceso de criopreservación de semen redujo los parámetros físicos del semen y estas pérdidas de calidad sufren interferencia según las razas evaluadas.O objetivo deste estudo foi avaliar parâmetros da qualidade espermática de sêmen fresco e após a descongelação de touros Aberdeen Angus, Holandês e Nelore. Foram utilizados 39 touros: Aberdeen Angus (n=13), Holandês (n=13) e Nelore (n=13). A colheita de sêmen foi realizada por vagina artificial duas vezes/semana, totalizando 792 colheitas de sêmen, sendo 307 para touros Aberdeen Angus, 225 para touros Holandês e 260 para touros Nelore. Após colheita, o sêmen fresco foi avaliado e em seguida realizada a congelação. Após a congelação, as partidas foram descongeladas e foi determinada a motilidade progressiva. A análise do sêmen fresco demonstrou que não houve diferença (P= 0,053) entre as raças Aberdeen Angus e Nelore, enquanto, que ejaculados de touros Holandês observou-se diferença estatística (P= 0,024). Assim como, foi identificado diferença (P<0,001) na concentração espermática das três raças. Nas amostras avaliadas pós-descongelação, observou-se diferença estatística entre touros Holandês e Nelore (P<0,001), enquanto, que os valores de touros Angus foram semelhantes às outras duas raças. A diferença da motilidade do sêmen fresco e pós- descongelação evidenciou que touros Nelore e Angus apresentaram maior variação dos valores entre as análises (26,0±8,9% e 25,3±8,4%, respectivamente) apresentando diferença significativa (P<0,001) em relação aos touros Holandês (20,6±9,3%) que obtiveram a menor diferença. A Análise do sêmen fresco e pós- descongelação não apresentou diferença significativa (P=0,13) entre as raças. Em conclusão, o processo de criopreservação do sêmen reduziu os parâmetros físicos do sêmen e estas perdas de qualidade sofrem interferência de acordo com as raças avaliadas.Research, Society and Development2021-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2338210.33448/rsd-v10i16.23382Research, Society and Development; Vol. 10 No. 16; e408101623382Research, Society and Development; Vol. 10 Núm. 16; e408101623382Research, Society and Development; v. 10 n. 16; e4081016233822525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/23382/21058Copyright (c) 2021 Diego André Costa Saranholi; Rafael Rocha de Paula; Edmilson Pytilak; Fabíola Afonso; Luis Felipe Canela; Ana Beatriz Marques de Almeida; Myrian Megumy Tsunokawa Hidalgo; Maria Isabel Mello Martins; Wanessa Blaschi; Thales Ricardo Rigo Barreiroshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSaranholi, Diego André CostaPaula, Rafael Rocha de Pytilak, Edmilson Afonso, FabíolaCanela, Luis FelipeAlmeida, Ana Beatriz Marques deHidalgo, Myrian Megumy TsunokawaMartins, Maria Isabel MelloBlaschi, WanessaBarreiros, Thales Ricardo Rigo 2021-12-20T11:03:07Zoai:ojs.pkp.sfu.ca:article/23382Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:16.395250Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
