四川藏鸡品种标准化初步研究

摘要

藏鸡作为我国国家级畜禽资源保护品种之一,具有适应高原低氧和气候多变环境的能力,是我国高原地区的主要地方原始小型品种.但因近年来外源鸡种入侵和近亲繁殖,致使不同产区的纯种藏鸡品质不均一,种鸡生理性能、繁殖性能等方面出现不同程度的减退.为保护纯种藏鸡,并为今后选育优质藏鸡提供理论依据和可行的实践方案;针对地理气候差异,制定出适合于各产区藏鸡的藏鸡品种标准十分必要.因此,本文根据对藏鸡四川主产区的调研、藏鸡的外貌特征观察、生产性能和繁殖性能的基础研究,并结合产区畜牧部门的相关资料,制定了藏鸡四川藏区品种初步标准.%Tibetan chicken is one of national conservation livestock breed resource. It mainly inhabits in Qinghai-Tibetan plateau and has an excellcnce capability of adapting plateau environment of bypoxia and unsettled weather. The irtrusion of the exogenous chicken and inbreeding resulted in falling off in quality of pure breed Tibetan chicken and the decline of physiological property and reproductive performance. In order to protect Tibetan chicken resource and provide the theoretical foundation for selecting and breeding high quality Tibetan chicken, it was necessary to enact a standard suit to different habitats with different gepgraphies and climates. A preliminary standard for breed Tibetan chicken was set up based on its morphological characters, physiological properties and reproductive performances and investigations in the main habitats.
