Data were analyzed with a statistical software program
(SAS version 9.3 for Windows, SAS Institute, Cary, NC, USA).
Differences in the mean BCS between treatments were
analyzed using one-way ANOVA (PROC GLM of SAS). Differences
in mean interval (hours) from CIDR insertion to
CIDR withdrawal, interval from CIDR removal, and time of
insemination between treatments were analyzed by
ANOVA; the Bartlett testwas used to assess homogeneity of
variance (PROC GLM of SAS). Because variances for the
mean interval were heterogeneous between treatments, a
log10 transformation was performed for testing differences.
However, all tables and figures are presented with
nontransformed values.
