摘  要：
自1974年从法国引进原种利木赞牛改良当地复州牛以来,辽宁省普兰店市现已形成存栏量12万头年出栏量5万头的利木赞改良牛规模。调查发现,普兰店地区多年通过推广利木赞牛人工授精技术,母牛群的外貌和体尺指标都与利木赞原种牛相接近,而显著优于复州牛。但由于长期缺乏完善的系谱登记制度,且饲养管理水平低,使得改良牛系谱混乱,遗传潜力未得到充分发挥。因此,建议当地有关部门应当尽快建立利木赞改良牛个体身份标识系统,同时加强营养供应,为我国利木赞牛品种或专门化品系的培育打下基础,并为实施全国肉牛追溯体系提供可用的信息,以推动肉牛业的健康和可持续发展。

摘  要：
Since introduction of pure Limousin breeds from France in 1974, the population of crossbred Limousin cattle has been developed into total inventory capacity of 120,000 head and an annual slaughter capacity of 50,000 head in Pulandian prefacture of Liaoning province. The survey data showed that the body shape and size traits of the crossbred Limousin cows were much similar to their original species, and greatly better than Fuzhou yellow cattle, because of a longterm popularization of artificial insemination technology. However, due to a poor pedigree registration system, and a low level of feeding and management, the high genetic potential of the animals has not been approached. Therefore, it is necessary to establish an individual identification system and improvement of nutritional supply so as to provide a suitable data-base for China animal breeding system and national beef cattle traceability as well as farmer's economical return.
