Abstract

Results from a 41 month study of West African Dwarf goats and sheep under village conditions in south-west Nigeria are reported. Even at a very low level of management these trypanosomiasis-tolerant animals produced 2.01 kids or 1.51 lambs per dam per year. Mortality of young particularly kids and low growth rates limit production. Of these mortality is probably the first constraint to increased productivity and profitability. Control of peste des petits ruminants appears to significantly reduce mortality and should stimulate the further development of this production system.

摘要

报告了在尼日利亚西南部乡村条件下对西非矮山羊和绵羊进行的为期41个月的研究结果。即使在管理水平非常低的情况下,这些耐锥虫病的动物每头母畜每年仍能产出2.01只小羊或1.51只羔羊。幼畜尤其是小羊的死亡率和低生长率限制了产量。其中,死亡率可能是提高生产力和盈利能力的首要制约因素。控制小反刍兽疫似乎能显著降低死亡率,并应能推动该生产系统的进一步发展。
