摘要

该研究在奥罗米亚民族地区州西哈拉格地区的Mieso和borde地区进行,目的是评估研究地区骆驼生产、繁殖性能和骆驼奶理化质量的主要制约因素。总共有目的地选择了120户(骆驼主人)进行访谈(即每个kebeles中有20户)。饲料短缺、自然资源短缺引发的冲突、牧场生产力低下和水资源短缺是制约骆驼生产的主要因素。公、母骆驼初次交配的平均年龄分别为5.92±2.91岁和4.79±1.84岁,每胎平均产仔数为1.73±0.64。研究区公、母骆驼的生殖期分别为20.04±6.50年和25.20±7.83年,本研究记录的骆驼妊娠期为1.73±0.64年。米索和博德骆驼的哺乳期分别为9.77±2.10和17.30±5.66个月。据报道,在米索地区,成熟晚是主要的生殖限制,其次是产犊间隔长、生殖疾病的存在、受孕率低和出生的小牛发育不良。而在博德德地区,主要的生殖限制是成熟晚,其次是生殖疾病的存在,产犊间隔长,受孕率低和出生的小牛发育不良。综上所述,骆驼是牧民生计中最重要的牲畜之一,是奶、肉和畜力的来源。为了提高骆驼的生产力,应注意诸如饲料和水短缺、疾病问题等主要制约因素。

Assessment on major production constraints, and reproductive performances of camel in West Hararghe Zone Oromia Ethiopia
The study was conducted in Mieso and Bordede districts, in West Hararghe Zone of Oromiya National Regional State with the objectives of assessing major constraints of camel production, reproductive performances, and physicochemical quality of camel milk in the study areas. A total of 120 households (camel owners) were selected purposively for interview (i.e 20 households from each kebeles). Feed shortage, conflict over the scarcity of natural resources, low productivity of grazing land, and water scarcity were the main constraints of camel production. The mean age at first mating for male and female camels was 5.92±2.91 and 4.79±1.84 years respectively, similarly, the average number of services per conception of camels in this finding was 1.73±0.64. The reproductive span of male and female camels in the study area were 20.04±6.50 and 25.20±7.83 years, respectively and the gestation period of camels recorded in this study was 1.73±0.64. The lactation length of a camel was 9.77±2.10 and 17.30±5.66 months in Mieso and Bordede, respectively. Late maturity is reported as the primary reproductive constraint followed by long calving interval, the presence of reproductive disease, low conception rate and the birth of stunted calves in Mieso district. Whereas in Bordede district the primary reproductive constraints were late maturity followed by the presence of reproductive disease, long calving interval, low conception rate and birth of stunted calf. In conclusion, camel is one of the most important livestock for pastoralists’ livelihood as a source of milk, meat and draught power. In order to increase the productivity of camels, the major constraints such as shortage of feed and water, disease problems and others should be given attention.
