Resumo: | The reproductive tracts of 64 Landrace, Largo White or crossed (Ld x LW) gilts culled for anestrus, from three total confined herds, were examined. Histological examination of genital tract were carried out in 34 gilts. The mean age at slaughter was 343 ± 2.52 days and 85.9 per cent of the gilts had small ovaries that had never ovulated. Six gilts (9.4%) were classified as behaviorally anestruous with cyclical ovarian activity on the basis of the presence of corpora lutea. No inflammatory changes were found in macroscopic and histological examination. The incidence of ovarian and paraovarian cysts was 6.25 and 7.81 per cent respectivelly. Three cases of hidrometra, and one case of ovotestis were recorded. High percentage of the examined pieces showed low development, with lack of follicular activity typical of delayed puberty. The number and nature of other functional and anatomical disturbances recorded had no great significance in the anestrus occurrence that lead to the gilts culling. |

De 34 leitoas foram colhidos fragmentos do aparelho genital para exame histológico. A idade das leitoas ao abate foi de 343 ± 2,52 dias; 85,9% delas possuíam ovários pequenos com pequenos folículos sem nunca terem ovulado. Seis leitoas (9,4%) apresentavam sinais de atividade cíclica pela presença de corpos lúteos nos ovários, sendo consideradas em anestro de comportamento. Não foram observadas alterações de natureza inflamatória nos exames macroscópico e histológico. A frequência de cistos ovarianos e paraovarianos foi de 6,25 e 7,81%, respectivamente. Registraram-se ainda três casos de hidrometra e um caso de ovotéstis. O quadro predominante nas peças examinadas mostrou falta de maturação folicular, com pouco desenvolvimento do trato genital, caracterizando puberdade retardada. A frequência e a natureza das outras alterações anatômicas ou funcionais encontradas não influenciaram significativamente o quadro de anestro que determinou o abate dos animais.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilveira, Paulo Roberto Souza daBarros, Severo Salles deWentz, Ilmo2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16106Pesquisa Agropecuaria Brasileira; v.19, n.9, set. 1984; 1169-1173Pesquisa Agropecuária Brasileira; v.19, n.9, set. 1984; 1169-11731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16106/10254info:eu-repo/semantics/openAccess2014-04-16T19:30:04Zoai:ojs.seer.sct.embrapa.br:article/16106Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:30:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
