dc.description.abstract [EN] A study was undertaken to determine, in tropical breeding conditions, the effect of mate presence and/or photoperiod on age at puberty attainment, oestrous behaviour and breeding performance in prepubertal female rabbits. The study involved 3 treatment groups of seven does each, designated as A, B and C. Group A, rabbits were exposed to both extended light (+ 6 hours) and male presence. Group B, does were subjected to extended light only, whereas those in group C were treated to male presence only. Group D rabbits which were not subjected to any of the two treatment factors (photoperiod and male presence) servad as the control group. The data obtained indicated that the does subjected to either one or both treatment factors attained puberty earlier (142.4 ± 2.0 days) than the control group (167.1 ± 5.0 days). Weight at puberty was also significantly (P<0.05) lighter (1.34 ± 0.04 kg) in the does exposed to male presence and/or photoperiod than the control group (1.50 ± 0.06 kg). Oestrous behaviour in terms of mean frequency and "intensity" of oestrus as well as length of the cycle were significantly (P<0.05) improved in the treatment groups than the control. The duration of oestrus (heat) was however shorter among the treatment groups. With respect to breeding performance, kindling rate was much higher among the treatment does (66.03 ± 2.8 %) than the control (50.00 ± 3.1 %). However, differences in gestation length, litter size and litter weight were not statistically significant (P>0.05). Pseudopregnancy in proportion of non fertile matings was significantly (P<0.05) higher among the treatment groups ( 50. 1 ± 2.3 % ) than the control ( 33.33 ± 3.5 % ). lt was concluded that the exposure of young female rabbits to male presence and/or photoperiod may serve as a useful and relatively inexpensive management tool in improving rabbit production in the tropics since the technique has the potential to induce early puberty, amplify behaviour eostrus and improve kindling ratas. es_ES
dc.description.abstract [FR] Cette étude a pour but d'évaluer l'intluence de la présence du male et/ou de l'éclairement sur /'age a la puberté, le comportement oestral et les pertormances d'élevage de lapines prépuberes, dans des conditions d'élevage tropical. Quatre groupes de 7 lapines ont suivis le traitement suivant : A - 6 heures supplémentaires d'exposition a la lumiere et présence du male. B - 6 heures supplémentaires d'exposition a la lumiere. C - présence du male. D - groupe témoin (aucun traitement). Les résultats obtenus indiquent que les lapines soumises soit a /'un des deux traitements ou aux deux combinés, atteignent plus t6t l'age de la puberté (142.4 ± 2.04 jours) que ce/les du groupe témoin (167.1 ± 5.0 jours). Le poids a la puberté est significativement (P<0.05) inférieur dans les 3 lots expérimentaux (1.34 ± 0.04 kg) par rapport au lot témoin (1.50 ± 0.06 kg). Le comportement oestral évalué en termes de fréquence moyenne et d'intensité de /'oestrus ainsi que la longueur du cycle sont significativement améliorés dans les groupes expérimentaux (P<0.05). En outre la durée de l'oestrus étaient plus courte dans ces groupes. Compte tenu des performances d'élevage, le taux de mise bas est plus élevé dans les lots expérimentaux (66.03 ± 2.8 %) que dans le lot témoin (50.0 ± 3.1 %). En outre, les différences de durée de gestation, de taille et de poids des portées n'étaient pas significatives (P>0.05). Par rapport aux saillies fécondes., le nombre de pseudogestations était significativement plus élevé (P<0.05) dans les groupes expérimentaux (50. 1 ± 2.3 %) que dans le groupe témoin (33.33 ± 3.5 %). On peut conclure que l'exposition des jeunes lapines a la présence du male et!ou a un éclairement prolongé peut etre un moyen utile et relativement peu onéreux d'améliorer la production cunicole tropicale puisque cette technique permet de favoriser une puberté précoce, d'amplifier le comportement oestral et d'améliorer les taux de mise bas.
