ABSTRACT
To identify areas of opportunity in the reproductive management of pig farms,
a questionnaire was developed consisting of 36 reagents, 18 directed to the
male management area and 18 to the female. In a second stage, the questionnaire
was validated by applying it to 15 cooperating farms. To corroborate the
information of the questionnaire, the inspection of
the reproductive management was carried out. Each reagent was assigned values
of 0: does not exert a
negative effect on the reproductive process, 1: slight effect, 2: intermediate effect
and 3: negative effect. The
average number of points per farm was 44.93; the area that obtained the worst percentage of points in the
reproductive management was the boars with 54.93%. No correlation was found
between the percentages of reagents
classified as deficiencies with the number of females (p > 0.05), a negative
correlation was found with the fertility percentage (p < 0.05) and total born
(p < 0.05). No correlation was found between general points and area points
with the number of females and the fertility percentage (p > 0.05), but there was
a negative correlation with the total number of piglets born (p < 0.05). No effect of the type of operator was found for the general
points (p > 0.05). There was also
no effect of the region for general points in both male and the female areas (p > 0.05). It is concluded that the instrument identifies weak points (WP) of reproductive
management.
