本研究比较了猪的性能和发展的不良行为与完整的尾巴，当饲养在稻草床系统或部分板条系统丰富的商业设备。猪先前在分娩笼中或与其泌乳母鼠或断奶后接受了不同的富集处理（生根箱、液体分配器、稻草垫料或无）。在10周龄时将猪分组混合，从那时起，每2周进行一次行为观察，主要关注有害的社会行为和富集使用。该研究表明，在部分板条系统中，尾部未断尾的猪可能有很高的咬尾风险，而稻草垫料可以防止咬尾的发展。环境的直接影响似乎对不良行为的发展产生了更大的影响，而不是早期生活的富集，增加一个简单的富集装置不能弥补部分板条系统的贫瘠环境中的缺陷。为了防止不良行为的发生，需要进行环境富集的功能设计。
The present study compared the performance and development of adverse behaviours of pigs with intact tails, when housed in a straw-bedded system or a part-slatted system enriched with a commercial device. The pigs had previously received different enrichment treatments (rooting box, liquid dispenser, straw bedding or none), either in the farrowing crate or with their lactating dam or post weaning. The pigs were mixed in groups at 10 weeks of age and from then on, every 2 weeks, behavioural observations were performed, focusing mainly on harmful social behaviour and enrichment use. The study showed that pigs with undocked tails can be at high risk of tail biting in part-slatted systems, whereas the straw bedding prevented the development of tail biting. The immediate effects of the environment seemed to exert a greater influence on the development of adverse behaviour than early life enrichment and adding a simple enrichment device could not compensate for the deficiencies in the barren environment of the part-slatted system. In order to prevent vice, functional design of environmental enrichment is required.
