摘要

进行这项研究是为了描述坦桑尼亚阿鲁梅鲁和摩迪地区红马赛羊的饲养方法和生产力。来自这两个地区的63名农民接受了采访。采用SPSS软件包对数据进行分析。所有农民(100%)实行粗放型生产系统,即绵羊与牛、山羊一起吃草。大多数(61.9%)农民使用公共土地放牧牲畜,儿童是劳动力的主要来源(69.0%)。近一半(50.8%)的农民表示,他们的羊主要补充玉米麸皮(65.6%)。已确定的制约生产的因素是疾病、干旱、缺乏资金、市场和推广服务不足、盗窃和捕食者。塑料围裙被发现是一种有效的本地技术,以控制交配和实行季节性繁殖。大多数马赛红羊的初产羔龄为13 ~ 18个月,产羔间隔为12 ~ 18个月。大多数羊在十月到一月之间产羔。双胞胎病例很少(15.9%),表明人群中双胞胎发生率较低。在羊群中选择繁殖公羊,许多农民(95.2%)更喜欢季节性繁殖,让母羊在雨季产羔。处置是为了获得收入,去除不育母羊,屠宰作为食物和仪式。一般来说,由于不良的饲养方法,红马赛羊的生产力很低。由此得出结论,改进管理有可能提高可持续生产和保护该品种。

Husbandry and Productivity of Red Maasai Sheep in Arumeru and Monduli Districts in Tanzania
This study was undertaken to describe the husbandry practices and productivity of the Red Maasai sheep in Arumeru and Moduli districts in Tanzania. Sixty three farmers from each of the two districts were interviewed. Data were analysed using SPSS computer package. All farmers (100%) practice an extensive production system where sheep graze together with cattle and goats. The majority (61.9%) of the farmers use communal land to graze their animals, and children are the main source (69.0%) of labour. Almost half (50.8%) of the farmers indicated to supplement their sheep with mainly (65.6%) maize bran. Identified constraints to production were diseases, drought, lack of capital, poor markets and extension services, thefts, and predators. A plastic apron was found to be an effective indigenous technique to control mating and practice seasonal breeding. Age at first lambing for the majority of Red Maasai sheep was 13 to 18 months and lambing intervals of 12 to 18 months. Most sheep lambed between October and January. Twinning cases were few (15.9%) indicating a low twinning rate in the population. Breeding rams were selected within flocks, and many farmers (95.2%) preferred seasonal breeding to allow ewes to lamb in the wet season. Disposals were done to get income, remove infertile ewes, and slaughter for food and rituals. Generally, the productivity of Red Maasai sheep was low due to poor husbandry practices. It was concluded that improved management was likely to enhance sustainable production and conserve the breed.
