A behavioral vision in analysis of ostrich performance under various systems of breeding [electronic resource].

Includes references.

This study was mainly carried out to give a behavioral vision during explanation of the fluctuation in both egg laying and fertility under different breeding systems. This vision was also exploited to clarify the difference of the latter productivity aspects with the managerial practices under the intensive system of breeding. Means of egg laying per 3 weeks under the intensive system increased significantly (P≤0.01) on sand. However, the mean of egg laying decreased in both concrete and mixed litters (concrete and sand) than that in sand. Total means of both egg laying and number of fertile eggs increased significantly (P≤0.01) under the semi- intensive system.
