Resumo: Data from 974 litters, being 78.33% produced by artificial insemination and 21.67% by natural mating, were analysed in order to compare the efficiency of the two methods. The data were collected in an industrial kind of swine operation. The average litter sire at birth, piglets born, piglets born alive, individual piglets weight and number of pigs weaned were respectively 10.92 ± 0.18; 10.74 ± 0.17; 1.50 ± 0.12 and 9.31 ± 0,17 for natural mating and 10.58 ± 0,11; 10.41 ± 0.10; 1.54 ± 0.09 and 9.14 ± 0.10 for artificial insemination. All of the contrasts between the parameters were analysed through the Student t-test and were not significant (P>0.05). First parity sows had no significant (P>0.05) differences between the two methods compared, but the pluriparous sows, naturally mated, had a significantly better performance (P<0.01) as for litter size at birth, piglets born alive and pigs weaned.

As médias de leitões nascidos, nascidos vivos, peso ao nascer e número de leitões desmamados foram de 10,92 ± 0,18; 10,74 ± 0,17; 1,50 ± 0,12 e 9,31 ± 0,17 versus 10,58 ± 0,11; 10,41 ± 0,10; 1,54 ± 0,09 e 9,14 ± 0,10 para monta natural e inseminação artificial, respectivamente. Todos os contrastes entre as variáveis foram analisados pelo teste t de Student. Não se constataram significância (P>0,05). Nas comparações isoladas das leitegadas obtidas pelos dois métodos na categoria de fêmeas de primeiro parto também não ocorreram diferenças significativas (P>0,05); entretanto, na categoria de porcas pluríparas constatou-se significância estatística (P<0,01) no total de leitões nascidos, nascidos vivos, e desmamados, a favor de porcas com monta natural.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilveira, Paulo Roberto S. daMunari, JorgeSobestiansky, JurijWentz, Ivo2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14746Pesquisa Agropecuaria Brasileira; v.21, n.3, mar. 1986; 311-316Pesquisa Agropecuária Brasileira; v.21, n.3, mar. 1986; 311-3161678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14746/8426info:eu-repo/semantics/openAccess2014-10-17T19:27:58Zoai:ojs.seer.sct.embrapa.br:article/14746Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-17T19:27:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
