Resumen:
The aim of this study was to determine whether sexually inexperienced
females could display proceptivity and receptivity behaviours as the
experienced, in the first exposure to males. Three groups of females (n=
9 each) were used: i) sexually inexperienced, ii) with complete sexual
experience, and iii) with limited sexual experience. Three male goats
were subjected to photoperiodic treatment for 2.5 months of long days to
stimulate their sexual activity during the natural sexual rest
(March-April). During anestrous season, females were exposed to
photo-stimulated males. Sexual behaviours were recorded during the first
three days post-introduction of the males into female groups, in two
daily periods of 20 min each. Sexually inexperienced females and those
with complete sexual experience showed higher tail wagging than those
with limited sexual experience (P< 0.001). Sexually inexperienced
females displayed higher female-female sniffing and emission of urine
than those groups with complete and limited sexual experience (P< 0.001
and P< 0.05, respectively). Females with limited sexual experience
displayed higher female-female mounts than those groups inexperienced
and with complete sexual experience (P< 0.05). In addition, females with
complete sexual experience displayed higher female-male sniffing than
those groups inexperienced and with limited sexual experience (P<
0.001). Receptivity behaviour did not differ between female groups (P>
0.05). We concluded that sexually inexperienced anestrous females
display proceptivity and receptivity behaviours as those sexually
experienced exposed to photo-stimulated males.
