摘要
摘要本研究旨在评估坦桑尼亚、中部地区、珍贵的Dodoma和Singida地区土生鸡种群的表型多样性。根据两个地区的鸡群潜力,有目的地选择了6个县。选取176只成年地方鸡(雌雄)进行体重估算、体重线性测量和表型性状视觉评价。结果表明,以单梳为主(90.9%),其次为豌豆梳(6.8%);主要的羽毛颜色是不同颜色的组合(66%),其次是黑色(14%)。黄小腿色(59.1%)在其他颜色中占主导地位。估计体重、体长、胸围和小腿长度的总体平均值分别为1.80 kg、39.3、31.3和8.8 cm。男性明显比女性重(2.2 vs 1.3 kg;p & lt;0.05)。大多数线性体测量性状的值差异有统计学意义(p <0.01)。各研究地区的胸围没有显著差异。目前的研究结果表明,研究地区的土鸡具有独特的遗传潜力,可用于进一步的育种计划,以便农村社区最佳地利用这些遗传资源。
Phenotypic characterisation of indigenous chicken in the central zone of Tanzania
Abstract The study was conducted to assess the phenotypic diversity within the indigenous chicken population in Tanzania, the central zone, preciously Dodoma and Singida regions. Six districts from two regions were purposively selected based on their potential for chicken population. A total of 176 adult local chickens of both sexes were used to estimate the body weight, linear body measurements and visual assessments of phenotypic traits. The results indicated that the predominant comb type was single (90.9%) followed by pea comb (6.8%). The dominant plumage colour was a combination of different colours (66%), followed by black (14%). Yellow shank colour (59.1%) was dominant over other colours. The estimated overall mean values of body weight, body length, chest circumference, and shank length were 1.80 kg, 39.3, 31.3, and 8.8 cm, respectively. Males were significantly heavier than females (2.2 vs 1.3 kg; p < 0.05). The values of most linear body measurement traits were significantly different ( p < 0.01). The chest circumference was not significantly different across the studied districts. The present finding suggests that indigenous chickens in the study area possess unique genetic potentials that would be used for further breeding programs for optimum utilisation of these genetic resources by the rural communities.
