RPOA dataset

Metabolic profile parameters at early and late RPOA (resumption of postpartum ovarian activity) were compared using a t-Student test for independent samples. A multivariate analysis of correlations between the main RPOA parameters and those of the postpartum metabolic profile was performed. In these processes, the statistical package Statgraphics Centurion Ver. XV.II was used. A cross-sectional observational analytical study was carried out to establish the association between RPOA and metabolic activity at 30 DPP. Measurements of frequency, impact and statistical significance were obtained using the EPIDAT 3.1 statistical package. Where the prevalence ratio (PR) indicates how many times more likely the animals exposed to each of the factors are to present late RPOA; the prevalence in exposed denotes the percentage of cows with delayed RPOA within each of the metabolic and nutritional disorders, due to being exposed to them, and the prevalence in unexposed indicates the percentage of cows with prolonged RPOA, without being exposed.
