Etude zootechnique du syndrome de chute de

ponte chez la poule pondeuse d'œufs de consommation

Résumé :

L'obtention de bonnes performances zootechniques en élevage de poules pondeuses nécessite un suivi continu et régulier pendant toute la période de production pour augmenter la rentabilité de l'élevage. Dans ce sens, nous avons réalisé une étude comparative dans deux élevages de poules pondeuses d'œufs de consommation dans la wilaya de Tizi-Ouzou durant une période de ponte, dans l'objectif d'étudier les facteurs zootechniques qui provoquent des chutes de ponte, à savoir les paramètres d'élevage et les conditions d'ambiance. Les résultats obtenus sur une période de ponte de 266 jours ne sont pas satisfaisants. Des chutes de ponte fréquentes sont constatées, avec un taux de ponte moyen de 72,62 % et un taux de mortalité

qui est de 8,35%.

Abstract :

Getting good production performance in laying hens requires a continuous and regular monitoring throughout the profitability of farming. In this sens, we performed a comparative study of two flocks of laying hens egg consumption, in the wilaya of Tizi-Ouzou during the laying period, in order to study the factors that cause livestock egg drop, namely breeding parameters and environmental conditions. Results obtained during the laying period of 266 days are not really good, we have valued frequent egg drops with an average of 72,62% and an a death average of 8,35%.
