影响猪场猪只生长性能自动测定设备数据正确性的因素及数据维护的意义

Factors Influencing the Data Correctness of Electronic Swine Performance Testing System and the Significance of Data Maintenance

猪场猪只生长性能自动测定设备现今在我国许多规模猪场已得到了广泛的应用,但其数据的正确性会受到多种因素的影响。如果不能保障生长性能测定数据的正确性,不仅会影响育种工作的效率,甚至会对育种工作产生误导。分析了影响猪场猪只生长性能测定数据正确性的3个根本因素:系统误差、设备运行过程中的随机影响因素和动物的行为干扰因素。并指出出错数据主要表现在4个方面:数据链中断、饲料中断、设备粘连、动物异常行为。需做好两方面的工作:加强管理以减少设备运行过程中影响数据正确性的因素,并对出错数据根据具体情况进行分析与维护,才能获得正确性高的数据。数据维护是自动设备的数据质量管理系统中的重要工作之一。只有进行分析与合理维护的测定数据,才能最大限度地展现测定动物的最真实的行为,体现测定数据的正确意义,让测定数据具有评估、应用和交流的实际意义。

Electronic Swine Performance Testing System(ESPTS)has been widely used in many large-scale intensive pig farms in China.The data correctness of ESPTS is influenced by a series of factors.If the porcine growth performance data cannot be guaranteed to be correct,the efficiency and direction of breeding work will be affected and misled.This study found that the data correctness of ESPTS was affected by three fundamental factors:the systematic error,the random impacting factor generating during the equipment running,and the interfering factor associated with animal behavior.We also pointed out that the incorrect data were mainly observed in the following four aspects:data-chain interruption,feeding supplying interruption,mechanical sticking on scales,and abnormal animal behavior.Two aspects of work are recommended to be done for ensuring the data correctness:enhancing management so as to control the emerging of factors affecting the data correctness;analyzing and revising the incorrect data according to the actual situation.Data maintenance is one of the most important works in data quality management system of ESPTS.The scientific analysis and rational maintenance of the data obtained from ESPTS can objectively reveal the animal behavior to the largest extent,embody the significance of the testing data,and make the data be of practical significance in evaluation,application and communication.
