Abstract

Guinea fowls are a source of high-value meat and eggs, and the birds are more disease resistant than other types of birds. A survey was conducted in ward 23, Chipinge district, Zimbabwe, to characterise guinea fowl management practices and to identify constraints and potential opportunities for increased guinea fowl productivity. Purposive sampling was used to select 84 out of possible 252 guinea fowl owners. Data were collected by direct observation on guinea fowl varieties, feeding strategies and housing facilities. A semi-structured questionnaire was used to collect data on farmer experiences, perceptions and common challenges encountered. A chi-squared test was conducted using the IBM SPSS Statistical Package for Social Sciences (SPSS) version 21. The study revealed that famers keep guinea fowls under free-range management. The average production indices were flock size 18 ± 12, egg production 89 ± 50, hatchability 63.8% and keet survival rate of 75%. Approximately 42.9% of the farmers provide supplementary feed albeit not systematically. There was a significant association between provision of supplementary feed and keet survival rate (χ  = 21.600, df = 2, P < 0.016) as well as provision of housing and flock size (χ  = 38.508, df = 3, P < 0.018). The housing provided was substandard. Major challenges faced by farmers were predation, low hatchability and lack of access to profitable markets. The provision of supplements and better housing for birds could improve guinea fowl productivity.

摘要

珍珠鸡是高价值肉类和蛋类的来源,而且这种禽类比其他类型的禽类更抗病。在津巴布韦奇平格区第23病房进行了一项调查,以描述珍珠鸡的管理做法,并确定提高珍珠鸡生产力的制约因素和潜在机会。采用目的抽样法从252名可能的珍珠鸡养殖户中选取了84户。通过直接观察收集了有关珍珠鸡品种、饲养策略和住房设施的数据。使用半结构化问卷收集有关农民经验、看法和遇到的常见挑战的数据。使用IBM社会科学统计软件包(SPSS)21版进行卡方检验。研究表明,养殖户采用自由放养管理方式饲养珍珠鸡。平均生产指标为鸡群规模18±12只、产蛋量89±50枚、孵化率63.8%、雏鸡成活率75%。约42.9%的养殖户提供补充饲料,但并非系统地提供。提供补充饲料与雏鸡成活率之间(χ = 21.600,自由度 = 2,P < 0.016)以及提供住房与鸡群规模之间(χ = 38.508,自由度 = 3,P < 0.018)存在显著关联。所提供的住房不合标准。养殖户面临的主要挑战是捕食、孵化率低以及缺乏进入盈利市场的机会。为禽类提供补充饲料和更好的住房可以提高珍珠鸡的生产力。
