To generate information essential for the implementation of breeding schemes suitable for village poultry producers in Ethiopia, a survey was conducted aimed at defining the socioeconomic characteristics of the production environments in different geographic regions, understanding the important functions of chickens, identifying farmers' choice of chicken breeds and the underlying factors that determine the choice of genetic stock used. The survey included both questionnaire survey and a participatory group discussion. A total of 225 households (45 households from each of five Woredas) were interviewed. The questionnaire was designed to collect data covering general information on village poultry production such as socio-management characteristics, production objectives, population structure, breed choice and trait preferences, market preferences of specific traits, and farmers' selection practices. The participatory farmers' discussions were designed to involve stakeholders in defining the breeding objective "traits" and deriving their relative importance in the production environment based on the different functions of chickens and "traits" identified in the interviews. The results showed that production of eggs for consumption is the principal function of chickens in most regions followed by the use as source of income and meat for home consumption. The production system in all geographic regions studied revealed similar features generally characterized by extensive scavenging management, absence of immunization programs, increased risk of exposure of birds to disease and predators, and reproduction entirely based on uncontrolled natural mating and hatching of eggs using broody hens. Farmers' ratings of indigenous chickens with respect to modern breeds showed the highest significance of the adaptive traits in general, and the superior merits of indigenous chickens to high yielding exotic breeds in particular. Adaptation to the production environment was the most important attribute of chickens in all the study areas. The high significance attributed to reproduction traits indicates the need for maintaining broody behavior and high level of hatchability while breeding for improved productivity of indigenous chickens for village conditions. The market price of chickens is primarily dictated by weight, but farmers rated growth (males) and number of eggs followed by growth (females) as the production traits they would like the most to be improved. Therefore, the ultimate breeding goal should be to develop a dual-purpose breed based on indigenous chicken genetic resources with any of the comb types other than single for all the regions studied having the most preferred white body plumage for farmers in the Amhara region and red body plumage for those in Oromia, Benshangul-Gumuz, and Southern regions.
为了生成对埃塞俄比亚乡村家禽养殖户实施合适育种计划至关重要的信息,开展了一项调查,旨在界定不同地理区域生产环境的社会经济特征,了解鸡的重要功能,确定农民对鸡品种的选择以及决定所使用遗传种群选择的潜在因素。该调查包括问卷调查和参与式小组讨论。共采访了225户家庭(来自五个区,每个区45户)。问卷旨在收集涵盖乡村家禽生产一般信息的数据,如社会管理特征、生产目标、种群结构、品种选择和性状偏好、特定性状的市场偏好以及农民的选择做法。参与式农民讨论旨在让利益相关者参与界定育种目标“性状”,并根据访谈中确定的鸡的不同功能和“性状”,得出它们在生产环境中的相对重要性。结果表明,在大多数地区,产蛋供消费是鸡的主要功能,其次是作为收入来源和家庭食用肉类。在所研究的所有地理区域,生产系统呈现出相似特征,总体特点是广泛的 scavenging管理、缺乏免疫计划、鸡接触疾病和捕食者的风险增加,以及繁殖完全基于不受控制的自然交配和使用抱窝母鸡孵化鸡蛋。农民对本地鸡与现代品种的评分表明,一般而言适应性性状最为重要,特别是本地鸡相对于高产外来品种具有优越性。在所有研究区域,适应生产环境是鸡最重要的属性。对繁殖性状的高度重视表明,在为乡村条件下提高本地鸡的生产力进行育种时,需要保持抱窝行为和高孵化率。鸡的市场价格主要由体重决定,但农民将生长(雄性)和产蛋数排在首位,其次是生长(雌性),作为他们最希望改进的生产性状。因此,最终的育种目标应该是基于本地鸡遗传资源培育一种兼用型品种,对于所有研究区域,除单冠外的任何冠型,阿姆哈拉地区的农民最喜欢白色体羽,奥罗米亚、本尚古勒 - 古穆兹和南部地区的农民则喜欢红色体羽。
