摘  要:
[目的 ]了解我国蛋鸡卫生的总体状况,确定蛋鸡场产蛋鸡的高死淘率的相关风险因素,[方法 ]联合各有关省份疫控中心等单位,在10个省份开展了蛋鸡卫生状况的流行病学调查。[结果 ]调查分析结果显示,2007至2011年间,全国蛋鸡养殖户数5年间降幅达43.7%,年均减少13.4%。调查场户中,87%以上的饲养海兰鸡或罗曼鸡。只有18%的场户会完全自己来销售鸡蛋,只有24.1%的场户会将淘汰蛋鸡直接销售给屠宰场。生物安全和饲养管理水平方面,随着蛋鸡饲养规模的增加而不断增加,其生物安全水平和饲养管理水平得分范围分别为60-90分和45-85分(100分为满分)。[结论 ]逻辑回归分析表明,"不实行全进全出制度"、"不记录病死情况"以及"饮用水不消毒"与产蛋鸡较高的死淘率呈正相关。

摘  要:
In order to learn the health situation in the main layer raising areas of china,and further to identify the risk factors relative to higher mortality of the layers,a survey was jointly conducted with provincial centers for animal disease control in 10 provinces. According to this survey,the number of layer farms had decreased by 43.7% from 2007 to 2011. 87% of the layer farms involved in the survey were raising Hyline and/or Roman breed. 18% of the farms sold their eggs by themselves,and only 24% of farms sold their spent hens to slaughterhouses directly. The management and biosafety practices we are improved along with the increase of the farm size. Logistic regression analyze suggested 3 risk factors relative to higher mortality,including"all-in-all-out not practised","Mortality not recorded" and "drinking water not disinfected".
