The study was conducted in Chifra district in Awsi-Resu zone of Afar Regional State to explore production objectives and strategies of sheep and goats in pastoral and agro-pastoral production systems. Cross-sectional survey with systematic random selection of 180 households (90 households from each production system was conducted. Descriptive statistics, t test, chi-square test, analysis of variance, and ranking method were employed in analyzing data using JMP-5 software. In pastoral production system, sheep and goat were primarily reared for household milk consumption, followed by live animal savings and income, while in agro-pastoral production system, sheep and goat are primarily reared for income, followed by household milk consumption and manure supply, as live animal savings. Overall mortality rates of sheep and goats (4 to >12 months of age) were 9 and 9.5 % in pastoral production systems while 7 and 6 % in agro-pastoral production system. Average age at first mating, kidding interval, days of mating after birth, weaning age, lactation length, litter size, slaughtering age, and marketable age of sheep and goats in pastoral production system were 7.4 months, 358 days, 29 days, 4.2 months, 3.1 months, 1.5 lambs, 7.4 months, and 14 months, respectively, while in agro-pastoral production system, they are 6.9 months, 353.3 days, 28 days, 3.2 months, 1.6 lambs, 6.4 months, and 14.5 months, respectively. It was concluded that production system-based development interventions could help to increase the productivity of sheep and goats and thereby enhance the livelihood of smallholders.
该研究在阿法尔州阿维-雷苏地区的奇夫拉区开展,以探究牧区和农牧结合生产系统中绵羊和山羊的生产目标及策略。采用系统随机抽样的方法,对180户家庭(每个生产系统各90户)进行了横断面调查。运用描述性统计、t检验、卡方检验、方差分析和排序方法,使用JMP-5软件对数据进行分析。在牧区生产系统中,绵羊和山羊主要用于家庭奶类消费,其次是作为活体储蓄和收入来源;而在农牧结合生产系统中,绵羊和山羊主要用于获取收入,其次是家庭奶类消费和提供肥料,作为活体储蓄。牧区生产系统中绵羊和山羊(4至大于12月龄)的总体死亡率分别为9%和9.5%,而农牧结合生产系统中分别为7%和6%。牧区生产系统中绵羊和山羊的初配平均年龄、产羔间隔、产后配种天数、断奶年龄、泌乳期长度、产羔数、屠宰年龄和上市年龄分别为7.4个月、358天、29天、4.2个月、3.1个月、1.5只羔羊、7.4个月和14个月,而在农牧结合生产系统中,分别为6.9个月、353.3天、28天、3.2个月、1.6只羔羊、6.4个月和14.5个月。研究得出结论,基于生产系统的发展干预措施有助于提高绵羊和山羊的生产力,从而改善小农户的生计。
