Abstract
Poultry is one of the most important subsectors of livestock, supplying a cheap source of good quality animal protein in the form of meat and eggs. This study was conducted to assess egg fertility, hatchability and egg quality parameters of indigenous chickens in the Hulla, Aleta Wondo and Dale districts, representing highland, midland and lowland agroecologies, respectively. Six kebeles (two kebeles from each district) were purposively selected based on a lower distribution of exotic chickens. A total of 750 eggs of indigenous chicken were collected from three different agro-ecologies, 450 eggs were used for fertility and hatchability evaluation, and 300 eggs were used for internal and external quality analysis. The collected data were analyzed using SPSS version 20 and SAS version 9.0 packages. The results indicated that agroecology has no significant effect on the fertility and hatchability of indigenous chicken eggs. The values of egg weight, egg length, shell weight, yolk weight, and yolk diameter and albumen weight of eggs collected from midland were higher than those of eggs from highland and lowland areas. However, the highest values for albumen height, yolk height and Haugh unit were observed on eggs collected from highland agroecology. In conclusion, agroecology has no effect on the fertility and hatchability of indigenous chicken eggs. However, agroecology significantly affects the internal and external egg quality of indigenous chicken eggs. Therefore, the storage condition and duration of storage need consideration to maintain the external quality of eggs.
家禽是畜牧业中最重要的分部门之一,以肉和蛋的形式提供廉价的优质动物蛋白来源。本研究对分别代表高原、中部和低地农业生态的Hulla、Aleta Wondo和Dale地区土鸡的产蛋率、孵化率和鸡蛋品质参数进行了评估。根据外来鸡的较低分布,有目的地选择了6只kebeles(每个区2只kebeles)。从3个不同的农业生态区共采集了750个土鸡蛋,其中450个用于育性和孵化性评价,300个用于内部和外部质量分析。采用SPSS version 20和SAS version 9.0软件包对收集的数据进行分析。结果表明,农业生态对土鸡蛋的育性和孵化率无显著影响。中部地区采蛋的蛋重、蛋长、壳重、蛋黄重、蛋黄直径和蛋白重均高于高原和低地地区采蛋的蛋重。而蛋白高度、蛋黄高度和哈氏单位均以高原农业生态采集的鸡蛋最高。综上所述,农业生态学对土鸡蛋的育性和孵化率没有影响。然而,农业生态学对土鸡鸡蛋的内在品质和外在品质影响显著。因此,为了保持鸡蛋的外在品质,需要考虑贮藏条件和贮藏时间。
