dc.description.abstract [EN] A total of 121 Pannon White female rabbits born with low (39-43 g) or high (63-70 g) weight were raised in litters of 6 or 1 O kits. Their reproductive performance (Al practiced 9-11 days after kindling) was controlled for 6 consecutive litters for a total of 300 kindlings. The does' birth weight had a significant effect on the number of inseminations necessary for the first kindling: the higher the birth weight of does, the lower their kindling rate. Later on, however, birth weight no longer affected the conception rate. With higher birth weight, significantly improved doe performance could be expected. Litter size at birth was 12.4% higher (9.52 vs 8.34; P:50.01 ), litter size at 21 days was 9.4% higher (7.64 vs 6.92; P:50.01) and litter weight at 21 days was 5.9 % greater (2.73 vs 2.57 kg; P:50.05) when the doe was born with greater weight. Total litter loss was 21.0% and 8.2% (P:50.01) for the high and low birth weight does, respectively. The size of the litters in which the does had been reared (6 or 1 O) did not influence their performance. es_ES
dc.description.abstract [FR] Un total de 121 lapines Pannon White, de faible (39-43 g) ou fort (63-70 g) poids a la naissance ont été élevés dans des portées de 6 ou 1 o lapereaux. Leurs performances ont été suivies (IA pratiquée 9-11 jours apres chaque mise bas) pendan! 6 portées consécutives, soit 300 mises bas au total. Le poids a la naissance des lapines a un effet significatif sur le nombre d'inséminations nécessaires pour obtenir la premiére mise bas : plus il est élevé plus le taux de mise bas est faible. Par la suite, le poids a la naissance n'affecte plus le taux de fécondité. Quand le poids a la naissance est élevé des performances dec reproduction plus élevées sont observées. Ainsi, la taille des portées a la naissance a été supérieure de 12,4% (9,52 vs 8,34 ; PS0,01 ), la tailles des portées a 21 jours a été supérieure de 9,4% (7.64 vs 6.92; P:50.01) et le poids de la portée a 21 jours a été de 5,9% supérieur (2.73 vs 2.57 kg; P:50.05) lorsque les lapines avaient un poids élevé a la naissance. Les perles totales de portées ont été de 21,0% et 8,2% pour les deux groupes, respectivement. La taille de la portée dans laquelle la mere est élevée (6 ou 1 O) n'influence pas ses performances.
