摘　　要：作为甘肃省重要的肉牛资源,早胜牛兼有可粗饲、抗严寒、适应力强等优良特征,对发展甘肃牛产业有着重要的意义。但在其选育、杂交改良过程中我们也要正视其存在着的问题,例如,优良资源流失、杂交改良计划缺失、管理技术落后等。本文就早胜牛选育提高和杂交改良的现状及面临的问题进行论述,并对其进一步发展提出建议。Zaosheng cattle is an important beef cattle variety resource in Gansu province, which has good characteristics of crude feed tolerance, cold-resistance and strong adaptability, and it also plays an important role in improving development of Gansu cattle industry. However, we must face up to the existing problems in the process of selection and cross improvement, such as the loss of good resources, the lack of hybrid improvement programs, and the backward management techniques. In this paper, the present situation and problems in selection and cross improvement of Zaosheng cattle were discussed, and the suggestions of further development of Zaosheng cattle were provided as well.
