Resumo: | The use of artificial insemination (AI) with heterospermic doses (Het) in swine may benefit reproductive performance by diluting individual differences among boars. However, such practice may also mask the true reproductive potential of some individuals, which can be measured through homospermic AI (Hom). This study evaluated boar reproductive performance after AI with Hom and Het doses. Ejaculates were collected from 4 boars and combined in 10 treatments: 4 with Hom doses (boars A, B, C and D) and 6 with Het doses (AB, AC, AD, BC, BD and CD) all having concentration of 3 billion spermatozoa in 80 mL doses with equal contribution of each boar. The in vitro analyses of sperm quality were: sperm membrane, DNA and acrossome integrity; mitochondrial functionality; and in vitro oocyte penetration. Thereafter, 511 females having parities from 1 to 6 were inseminated and the farrowing rate (FR) and total litter size (TB) were recorded. Both FR (Hom = 90.5% and Hem = 89.9%), and TB (Hom = 12.4 ± 0.4 and Het = 12.7 ± 0.7) did not differ (P>0,05). Some differences were observed among treatments, such as: the maximum FR (98.0%) for treatment AC and the minimum (87.0) for boar B; and a difference of two piglets among the maximum (for the CD treatment) and the minimum observed value (for the AC treatment). The only difference observed on the in vitro evaluations (P<0.05), occurred for the in vitro oocyte penetration by sperm from boars B (56.4%) and C (29.0%). No differences were detected in reproductive performance after AI using homospermic and heterospemic doses. |

No entanto, esta prática pode mascarar o potencial reprodutivo de outros reprodutores, o que poderia ser avaliado com o uso de inseminação artificial com doses homospérmicas (Hom). Este trabalho avaliou o desempenho reprodutivo de machos suínos após IA com doses Hom e Het. Ejaculados colhidos de 4 machos foram combinados em 10 tratamentos: 4 com doses Hom (machos A, B, C e D) e 6 com doses Het (AB, AC, AD, BC, BD, e CD), todos com concentração de 3 bilhões de espermatozóides em doses de 80 mL, com contribuição igual de cada macho. Realizaram-se testes para analise de integridade da membrana, do DNA espermático e do acrossoma, da funcionalidade da mitocôndria e da penetração ovocitária in vitro. Foram inseminadas 511 fêmeas de ordem de parto de 1 a 6. A taxa de parição (TP) e o número total de leitões nascidos por parto (TN) foram registrados. Tanto a TP (Hom = 90,5% e Het = 89,9%), quanto o TN (Hom = 12,4 ± 0,4 e Het = 12,7 ± 0,7), não diferiram (P>0,05). Foram observadas algumas diferenças entre os tratamentos, como a TP máxima ocorrendo para o tratamento AC (98.0%) e uma TP mínima de 87.0% para o macho B (P<0.05). Quanto ao TN, uma diferença de 2,0 leitões foi observada entre o valor máximo (tratamento CD) e o mínimo (tratamento AC). Quanto às avaliações in vitro, foram observadas diferenças apenas quanto ao teste de penetração in vitro (P<0,05), entre os machos B (56,4%) e C (29,2%). Não foram detectadas diferenças no desempenho reprodutivo com IA com doses homo e heterospérmicas.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em VeterináriaUFPelBRVeterináriaVeterináriaTaxa de pariçãoTamanho de leitegadaMachos suínosPenetração ovocitária in vitroFarrowing rateLitter sizeBoarsIn vitro oocyte penetrationCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIA::REPRODUCAO ANIMALDesempenho reprodutivo com inseminação artificial em suínos com doses homospérmicas e heterospérmicasReproductive performance with homospermic and heterospermic artificial insemination in swineinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/1834201505109830http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4793234U8Bianchi, Ivanhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4768000E7Lucia Júnior, ThomazSávio, Daniel Borgesinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALDissertacao_daniel_savio.pdfapplication/pdf201214http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2467/1/Dissertacao_daniel_savio.pdff8921438dab6324aed14b7b44d06de38MD51open accessTEXTDissertacao_daniel_savio.pdf.txtDissertacao_daniel_savio.pdf.txtExtracted Texttext/plain52851http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2467/2/Dissertacao_daniel_savio.pdf.txt99360ddc97be91d01ee126d38cf012b9MD52open accessTHUMBNAILDissertacao_daniel_savio.pdf.jpgDissertacao_daniel_savio.pdf.jpgGenerated Thumbnailimage/jpeg1483http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2467/3/Dissertacao_daniel_savio.pdf.jpg39934070110e01d57351048be783ded6MD53open access123456789/24672019-09-13 09:46:53.19open accessoai:guaiaca.ufpel.edu.br:123456789/2467Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2019-09-13T12:46:53Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |

Both FR (Hom = 90.5% and Hem = 89.9%), and TB (Hom = 12.4 ± 0.4 and Het = 12.7 ± 0.7) did not differ (P>0,05). Some differences were observed among treatments, such as: the maximum FR (98.0%) for treatment AC and the minimum (87.0) for boar B; and a difference of two piglets among the maximum (for the CD treatment) and the minimum observed value (for the AC treatment). The only difference observed on the in vitro evaluations (P<0.05), occurred for the in vitro oocyte penetration by sperm from boars B (56.4%) and C (29.0%). No differences were detected in reproductive performance after AI using homospermic and heterospemic doses. |
