The central dry zone of Myanmar is the area with the highest density of small-scale livestock farmers under harsh environmental condition. In this study, we describe and quantify ownership patterns for various livestock species and characterised management and husbandry practices of small-scale farmers. In addition, we identify the husbandry factors associated with selected outcome indicators, 'herd or flock size' and 'purpose of rearing'. A total of 613 livestock farmers in 40 villages were interviewed. Multispecies rearing was common with 51.7% of farmers rearing more than one livestock species. Rearing animals to be sold as adults for slaughter (meat production) was more common for small ruminants (98.1%) and chickens (99.8%) compared to cattle (69.8%). Larger cattle herds were more likely to practice grazing (p < 0.001) and to employ labour from outside the household to manage cattle than medium or small herds (p = 0.03). Patterns of grazing differed significantly between seasons (p < 0.01) for cattle, but not for small ruminants and village chicken. Overall, multispecies rearing and species-specific husbandry practices are used to raise livestock under harsh environmental conditions. Our results reveal that herd/flock size and purpose of rearing across different livestock species were significantly associated with feeding and housing practices and experience of farmers.
缅甸中部干旱地区是在恶劣环境条件下小规模畜牧养殖户密度最高的地区。在本研究中,我们描述并量化了各类牲畜的养殖模式,并对小规模养殖户的管理及饲养方式进行了特征分析。此外,我们还确定了与选定的产出指标“畜群或禽群规模”和“饲养目的”相关的饲养因素。共采访了40个村庄的613名畜牧养殖户。多物种养殖很常见,51.7%的养殖户饲养一种以上的牲畜。与牛(69.8%)相比,将小反刍动物(98.1%)和鸡(99.8%)饲养至成年后出售用于屠宰(肉类生产)更为普遍。较大的牛群比较中型或小型牛群更有可能实行放牧(p < 0.001),并且更有可能雇佣外来劳动力管理牛群(p = 0.03)。牛的放牧模式在不同季节之间存在显著差异(p < 0.01),但小反刍动物和乡村鸡的放牧模式则没有差异。总体而言,在恶劣环境条件下,人们采用多物种养殖和特定物种的饲养方式来饲养牲畜。我们的研究结果表明,不同牲畜物种的畜群/禽群规模和饲养目的与养殖户的饲养和圈舍管理方式及经验显著相关。
