Resumo: Rectal examination and vaginoscopy were utilized to evaluate ovarian activity and uterine involution, at regular intervals, from the 5th to the 40th day postpartum in 160 Canchim (5/8 Charolais – 3/8 Zebu) cows. Total uterine involution was observed in all animals and the least squares mean was equal to 25.40 days. Cow weight at calving (P < 0.05) and parity number (P < 0.01) affected time of uterine involution. The regression coefficient of time of uterine involution on cow weight at calving was 0.015 ± 0.007, indicating that heavier cows involuted later. Time of involution increased from 22.94 days the primiparous to 27.26 days for those with five or more calvings. A proportion of 37.50% of the animals presented smooth ovaries with no evidence of clinical function by the 40th day postpartum. The parturition-first estrus interval was 127.79 days.

A involução completa do útero ocorreu em todos os animais, apresentando média dos quadrados mínimos de 25, 40 dias, e foi influenciada significativamente pela ordem de parição (P < 0,01) e pelo peso das vacas ao parto (P < 0,05). O coeficiente de regressão do tempo de involução em relação ao peso da vaca foi de 0,015 ± 0,007, indicando que o útero das vacas mais pesadas involuiu mais tardiamente. O tempo de involução aumentou de 22,94 dias nas vacas primíparas, para 27,26 dias naquelas de cinco ou mais partos. Ao final do experimento, constatou-se que 37,50% dos animais apresentavam-se com os ovários afuncionais, e o intervalo parto-primeiro cio foi de 127,79 dias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBügner, ManfredAlencar, Maurício Mello de2014-10-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15902Pesquisa Agropecuaria Brasileira; v.20, n.8, ago. 1985; 883-888Pesquisa Agropecuária Brasileira; v.20, n.8, ago. 1985; 883-8881678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15902/9991info:eu-repo/semantics/openAccess2014-04-17T11:58:54Zoai:ojs.seer.sct.embrapa.br:article/15902Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T11:58:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
