Hormone profiles around the first observed estrus following
resumption of ovarian cyclicity
Descriptive statistics of hormone and ovarian cycle parameters
for cows in which estrus was observed are shown in Table 3.
Lameness score was an explanatory variable related to maximum
progesterone concentrations prior to estrus (P=0.050). Furthermore,
and when lameness score was included in the model, prior
fertility treatment was not a significant explanatory variable
