陕西关中地区非洲鸵鸟适应性研究

通过对引入陕西的120只非洲黑颈鸵鸟行为、生命体征、生产性能、抗病性能研究。结果发现,非洲黑颈鸵鸟引入陕西关中地区后三大生命体征平稳,抗逆性强,采食行为、性行为正常,生长发育、繁殖性能保持稳定上升状态。子二代种鸟的开产日龄无异于原非洲种鸟,且产蛋数、种蛋受精率和孵化率于开产第三年时达稳产、高产状态。子二代鸟在生长速度方面与子一代鸟比较,表现为平均日增重曲线峰值前移和达90公斤体重的饲养月龄提前一个月。非洲种鸟引入后,表现出了该物种独特的适应性、抗逆性及优秀的经济性能。

Study on Adaptability of Africa Ostrich in Guanzhong Region of Shaanxi Province

In this article,the behavior,vital signs,reproductive performance and disease resisting per for mame of 120 Afoica Black-neck Ostriches imported into Shaanxi were studied in order to investigate various indexes for it.The result showed that all the indexes mentioned.above all keep better,especially for the second filial generation.The egg-Laying mcmber,fertility rate and hatchability rate all reached highest in the srd year of prodaction.ln compar is on to the first filial generation,the second filial generation grew faster and the curve for daily weight gain put forward.Therefoe,after imported into shaanxi,the Africa Ostriches can adapt the environment and resist diseases,which indicates an excellent economical per for mance.
