Quantitative information about equine mortality is relatively scarce, yet it could be of great value for epidemiological purposes. In France, data from rendering plants are centralised in the Fallen Stock Data Interchange database (FSDI), managed by the French Ministry of Agriculture, while individual equine data are centralised in the French equine census database, SIRE, managed by the French horse and riding institute (IFCE).
To evaluate whether the combined use of the FSDI and SIRE databases can provide representative and accurate quantitative information on mortality for the French equine population and to propose enhancements of these databases to improve the quality of the resulting demographic information.
Descriptive study.
Mortality ratios for the French equine population were calculated per year between 2011 and 2014 and temporal variations in equine mortality modelled during the same period. Survival analyses were performed on a sample of equines traceable in both the FSDI and SIRE databases.
Estimates of the annual mortality ratios varied from 3.02 to 3.40% depending on the years. Survival rates of equines 2-years-old and over differed according to breed categories with the highest median age at death for the ponies. The weekly description of mortality highlighted marked seasonality of deaths whatever the category of equines. Modelling temporal variations in equine mortality also brought to light excess mortality.
Insufficient traceability of equines between the two databases.
The FSDI database provided an initial approach to equine death ratios on a national scale and an original description of temporal variations in mortality. Improvement in the traceability of equines between the FSDI and SIRE databases is needed to enable their combined use, providing a representative description of equine longevity and a more detailed description of temporal variations in mortality.
关于马死亡率的定量信息相对较少，但对于流行病学目的而言可能具有很大价值。在法国，来自屠宰场的数据集中在由法国农业部管理的“牲畜死亡数据交换数据库”（FSDI）中，而个体马的数据则集中在由法国马术协会（IFCE）管理的法国马普查数据库SIRE中。
评估FSDI和SIRE数据库的联合使用能否为法国马种群提供具有代表性和准确性的死亡率定量信息，并提出对这些数据库的改进措施以提高所得人口统计信息的质量。
描述性研究。
计算了2011年至2014年期间法国马种群的年死亡率，并对同一时期马死亡率的时间变化进行了建模。对在FSDI和SIRE数据库中均可追踪的马样本进行了生存分析。
根据年份不同，年死亡率估计值在3.02%至3.40%之间变化。2岁及以上马的存活率因品种类别而异，其中矮种马的死亡中位年龄最高。对死亡率的每周描述突出了无论马的类别如何，死亡都存在明显的季节性。对马死亡率时间变化的建模还揭示了超额死亡率。
两个数据库之间马的可追溯性不足。
FSDI数据库提供了一种在全国范围内初步了解马死亡率的方法以及对死亡率时间变化的原始描述。需要提高FSDI和SIRE数据库之间马的可追溯性，以便能够联合使用它们，从而提供对马寿命的代表性描述以及对死亡率时间变化更详细的描述。
