“…Lighting programs are widely used in avian species. Moreover, supplemental lighting programs produced positive effects on female reproductive precocity, kindling rate, and litter size at birth in rabbits under tropical conditions in Nigeria and Guadeloupe (Berepubo et al 1993;Depres et al 1996). Moreover, in seasonally breeding Syrian hamsters, day length influenced the copulatory behavior as males ceased to display ejaculatory behavior after several weeks of exposure to short day lengths (Powers et al 1989;Miernicki et al 1990).…”

“…To date, the precise nature of the pheromones or signals supposedly exchanged between the male and female rabbits is unknown. However, it appears that male presence is beneficial to receptivity and fertility in nulliparous does (Lefèvre et al, 1976;Berepudo et al, 1993) but not in lactating does (Kustos et al, 2000;Eiben et al, 2001;Bonanno et al, 2003).…”

ABSTRACT:The aim of this study was to determine the response to combinations of male stimuli in the oestrous doe in terms of changes in vulva colour, exfoliated cells in the vaginal lumen and the ovarian histology. Twelve oestrous heterogeneous rabbits does (6 multiparous and 6 nulliparous) were allotted equally to 3 experimental treatments: VIC-Male exposure with visual contact; NVC-Male exposure without visual contact and; NOCFemales completely isolated and not allowed any contact with the male. The does were placed under these treatments for 30 consecutive days during which vulvar colour was checked and vaginal smears were taken daily for each animal. All animals were sacrificed on the 30 th d and their ovaries processed for histological examination. Does with NVC and VIC exposure displayed either red or purple vulva in 95 and 90% of cases, respectively, the remaining cases being pink coloured but never a whitish vulva (P<0.05), whereas does with NOC exposure displayed pink vulva on 80% of the days checked and another 11.7% cases with white vulvae but never a reddish vulva (P<0.05). The proportions of superficial, intermediate and parabasal epithelial cells in the vagina smears showed that superficial cells usually contribute less than 16% of the total and are also less abundant (P<0.05) irrespective of the doe's exposure type or parity status. All categories of follicles were seen on ovarian sections from NVC and VIC does, but corpora lutea were also present on the sections from VIC does, whereas only follicles below 0.5 mm diameter were seen on the sections from NOC does. In conclusion, these results suggest that the rabbit does require some form of stimulus from the male to remain sexually attractive. Moreover, ovulation appeared to have been induced in the does with visual contact with the male, probably in conjunction with auditory and olfactory, but without tactile or mating contacts.

“…Other authors indicate that doe sexual heat is greater on the first day than on the tenth day post-partum (Perrier et al, 1982;Surdeau et al, 1982). Cudnovskii (1957) and Berepubo et al (1993) claimed that the natural receptivity cycle of a doe is 5 to 7 days, with duration as short as 6 to 7 hours during some times of the year. Our study agrees with the previous results because we used doe on the next day after delivery.…”

“…The "buck presence" is intended for the continuous contacts of visual, auditory, olfactory and tactile between the male and female (McNitt, 1992 andBerepubo et al, 1993). Several Studies have demonstrated that separation of the doe from its litter for short periods of time is very effective in stimulating ovarian activity of the doe.…”

Natural estrus induction methods were used in non receptive female rabbits for mating. Methods used were litter separation in the suckling females or presence of a female near buck cage in the non-suckling females of two differnt breeds, Baladi Red (BR) and New Zealand White (NZW). Treatments showed pronounced improvement in both breeds in terms of receptivity to males and conception rate. The NZW rabbits doe showed improvment in receptivity up to 68% in non-suckling and 73% in suckling females, while the percentages in Baladi rabbits were 72% and 79% in non-suckling and suckling ones, respectively. In addition, natrual methods tended to enhance conception rate in NZW rabbits to 74% in non-suckling and 56% in suckling females, while the corrseponding values of Baladi does were 71% and 55%, respectively. Significant decrease was observed in prolactin hormone level in response to litter separation from 42 to 6 ng/ml in NZW and from 15 to 2 ng/ml for Baladi does. However, progesterone was increased from 0.9 to 2.2 ng/ml in litter separation method and from 1.5 to 11.5 ng/ml in presence beside male cage in NZW rabbits. In Baladi does, values of progesterone hormone were increased from 0.8 to 6.7 ng/ml in litter separation and from 3.8 to 12.1 ng/ml in presence beside male cage. Estrogen levels of NZW does showed insignificant increase after litter separation and significant increase after presence beside male cage (48 to 63 pg/ml). In addition, Baladi rabbits had insignificant increase after litter separation. However, significant increase in estrogen values (from 47 to 56 pg/ml) after treatment were observed by presence beside male cage. Generally, the natural methods used to induce estrus in NZW and Baladi rabbits were successful and applicable. They can be widely used in rabbit farms instead of hormonal methods.
