Relationships among the cervical mucus urea and acetone, accuracy of insemination timing, and sperm survival in Holstein cows

Popis výsledku v původním jazyce

The objectives of study were to evaluate the relationships among urea and acetone content in cows? cervical mucus (CM), its crystallization type (CT) and sperm survival (SS) after timed AI. Samples of CM were collected from 192 Holstein cows treated by Ovsynch? protocol. Analysis of the urea and acetone content for identification of the metabolic status, the arborization test for evaluation of insemination timing and the short-term heat test of SS for assessment of its suitability as a biological matrixwere performed. The data set was analyzed by the GLM procedure using SAS?. The results documented the existence of substantial differences in individual response to the Ovsynch? protocol causing insemination of 55.21% cows at an inappropriate time. Theurea content was found as a possible indicator of a cow?s metabolism resp. of insemination timing, when level lower than 500 mg.l-1 corresponded (P < 0.05 ? 0.01) to the cows? expected response to timed AI. The higher the urea content, th
