Abstract

Despite its importance to social and economic life in arid and semi-arid regions of Algeria, the dromedary camels has received little scientific attention in our country. This research focuses on two aspects of this animal in its natural environment. An individual monitoring of 14 reproductive parameters in 110 breeding camelids over 18 months and a single analysis of blood biochemical parameters in 212 animals was performed. The results reveal that the camel breeding season lasts from October to June, with an oestrus or “heat” duration (7.7 ± 1.4 days), mating duration (25±10 min), gestation duration (377 ± 9.4 days), labour duration (37.7 ± 15 min), delivery duration (37.9 ± 10 min), duration of return to oestrus after parturition (30.3 ± 11.7 days), average duration between parturition and fertilising oestrus (216 ± 137.7 days), rate of females returning to oestrus after parturition (77.2 %), fertility rate (54.11±10.6 %). Our findings for blood biochemical parameters show average glycemia (1.21 ± 0.04 g/l), proteinemia (63.8 ± 73 g/l), uremia (432.54 ± 17.4 mg/l), triglyceride levels (487.66 ± 86 mg/l), cholesterol (318.7 ± 32 mg/l), lipids (3 ± 0.31 g/l), calcium (87.45 ± 3.7 mg/l), phosphorus (46.5 ± 3.95 mg/l) and magnesium (23.47 ± 2.25 mg/l). Statistical analysis indicates that age, gender, and production status significantly affected most of blood biochemical parameters (p ≤ 0.001). The findings were compared to those of other authors from other countries. Research, understanding, and improvement of the dromedary camels breeding system remain crucial in Algeria.

阿尔及利亚南部广泛养殖母骆驼繁殖状况及血液生化指标测定

尽管单峰骆驼对阿尔及利亚干旱和半干旱地区的社会和经济生活具有重要意义，但在我国却很少受到科学关注。这项研究主要关注这种动物在自然环境中的两个方面。在18个月的时间里，对110只繁殖骆驼的14项生殖参数进行了单独监测，并对212只动物的血液生化参数进行了单次分析。结果表明：骆驼的繁殖期为10 ~ 6月，发情期（7.7±1.4 d）、交尾期（25±10 min）、妊娠期（377±9.4 d）、产程（37.7±15 min）、分娩期（37.9±10 min）、产后回发情期（30.3±11.7 d）、平均产至受精卵期（216±137.7 d）、产后回发情率（77.2%）。生育率（54.11±10.6%）。血液生化指标：平均血糖（1.21±0.04 g/l）、蛋白血症（63.8±73 g/l）、尿毒症（432.54±17.4 mg/l）、甘油三酯（487.66±86 mg/l）、胆固醇（318.7±32 mg/l）、脂质（3±0.31 g/l）、钙（87.45±3.7 mg/l）、磷（46.5±3.95 mg/l）、镁（23.47±2.25 mg/l）。统计分析显示，年龄、性别、生产状况对大部分血液生化指标有显著影响（p≤0.001）。研究人员将这些发现与其他国家其他作者的研究结果进行了比较。对阿尔及利亚单峰骆驼育种系统的研究、了解和改进仍然至关重要。
