杜泊羊的适应性生长规律观察报告

摘要

The environmental adaptability of 50 embryo progenies of Dorper sheep in Baotou region of Inner Mongolia which were introduced from Australia were observed, and their growth and development status were also determined. Results showed that some indexes like rectal temperature, heartbeat, respiration, unhairing and ingestion, etc. of lamb, young and adult Dorper sheep had no obvious significance with them in origin place, furthermore some indexes like body weight, withers height, body length and chest width, etc. of them also met the characteristic requirements of Dorper sheep varieties. It is indicated that Dorper sheep show a good adaptability in Baotou region of Inner Mongolia. It provides relative theoretical basis for the feasibility of introducing Dorper sheep varieties and also has practical significance in guiding the crossbreeding and improvement of meat sheep breeds.%对内蒙古包头市从澳大利亚引进的50只杜泊羊胚胎后代进行环境适应性观察，并对其生长发育状况进行了测试。结果表明，杜泊羔羊、青年羊和成年羊在肛温、心跳、呼吸、脱毛和采食等指标与在原产地时无明显差异；体重、体高、体长和胸宽等指标也达到杜泊羊的品种特性要求。说明杜泊羊在内蒙古包头地区具有较好的适应性，这就对引进杜泊羊品种的可行性提供了相关的理论依据，并对指导肉用羊杂交改良具有现实意义。
