Resumo: With the objective of identifying predictors of fertility in bulls, the correlation coefficients of the midpiece length of bovine spermatozoa with semen traits and fertility were estimated. Data were obtained from semen samples of 50 crossbred bulls submitted to a progeny test. The midpiece length was determined in 40 midpieces of each bull through a image analysis system (Videoplan). Besides the physical traits before and after semen freezing, the oxygen consumption rate and the cytochemical activity index were observed. The correlation coefficients were low and non-significant (P>0.05), indicating that the midpiece length is not a good predictor of fertility.

Visando identificar preditores de fertilidade em touros, foram estimados os coeficientes de correlação do comprimento da peça intermediária (CPI) dos espermatozóides com características físicas e metabólicas do sêmen e fertilidade. Utilizaram-se amostras de sêmen de 50 touros mestiços, submetidos a teste de progênie. O CPI foi determinado em 40 espermatozóides de cada touro por um sistema de análise de imagens (Videoplan). Além das características físicas antes e após a congelação, foram verificados a velocidade do consumo de oxigênio e o índice de atividade citoquímica do sêmen desses touros. Os coeficientes de correlação entre o CPI e os resultados da avaliação física e metabólica do sêmen e fertilidade foram baixos e não significativos (P>0,05), não sendo o CPI considerado como um bom indicador da fertilidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarbosa, Rogério TaveiraEsper, César Robertode Freitas, Alfredo Ribeiro1998-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4991Pesquisa Agropecuaria Brasileira; v.33, n.10, out. 1998; 1661-1665Pesquisa Agropecuária Brasileira; v.33, n.10, out. 1998; 1661-16651678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4991/7155info:eu-repo/semantics/openAccess2015-01-20T17:28:02Zoai:ojs.seer.sct.embrapa.br:article/4991Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-01-20T17:28:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
