Clarifying frustrated behaviors as indicators in animal welfare and an assess ment of intensive husbandry systems

本研究包括三个部分，即文献综述、挫折行为的澄清和从动物福利的角度对集约化畜牧业系统的评价.由于日本人长期以来没有虐待法尔斯动物，所以直到现在我们才认真考虑保护法尔斯动物。然而，动物生产学会从1985年开始对动物福利进行调查和讨论，现在认为动物生产系统不仅要从生产力考虑，还要考虑动物福利. 1.阐明挫折下的行为用操作数条件化方法研究了犊牛的行为需要，结果表明犊牛也有运动和社会行为的需要。时间花费autoroming，破坏，咬inanimates，吸吮inanimates除了休息下的行为剥夺小牛增加。长颈鹿被观察调查的原因， ...更多信息 滚雪球限制、社会压力、环境和饲料的简化会增加卷舌现象。提示翻舌是心理应激下的一种受挫行为.集约化饲养制度的评价单圈人工饲养犊牛的社会行为、吸吮行为、活动行为和探究行为受到抑制，非营养性吸吮行为、破坏行为和躺卧行为受到促进。卷舌术在用栓系的牛的育肥中尤其得到推广。育肥牛的帕拉卷舌在栓系后不久即出现，并逐渐发展为定型卷舌。在肥育的最后阶段，卷舌减少。舌头滚动的表现抑制了沮丧的行为，即自我梳理和反刍。卷舌表演者往往是没有内部病变的动物。此外，卷舌表演者的数量有随着胴体等级的增加而增加的趋势。这些结果表明，在行为限制条件下，滚舌对心理应激具有抑制作用。笼养蛋鸡与产蛋有关的调查行为、活动行为、社会行为和繁殖行为受到抑制。据认为，啄食行为，而不获得饲料和异常行为增加，相应的这些行为的限制。少

This project consist of 3 parts, that is, a review of literatures, a clarification of behaviors under frustration, and an assessment of intensive husbandry systems from the viewpoint of animal welfare.1. A revieAs Japanese have not abused fars animals for a long time, we have not considered seriously the protection of fars animals until now. However, the society of animal production started to investigate and discuss animal welfare from 1985 and now it is thought that animal production systems should be considered not only from productivity but also animal welfare.2. A clarification of behaviors under frustrationBehavioral needs of calves were investigated in terms of an operand conditioning method, which showed that calves had needs for kinetic movements and social behaviors, too. Times spent autogrooming, ruinating, biting inanimates, and sucking inanimates in addition to resting were increased under behavioral deprivation in calves. Giraffes were observed to investigate causes of to … More ngue-rolling. Tongue-rolling increased under restriction, social stress, simplication of the environment and feed. suggesting that tongue-rolling was one of frustrated behaviors under psychological stress.3. An assessment of intensive husbandry systemsSocial behavior, suckling behavior, moving behavior and investigating behavior were suppressed and non-nutritive sucking behavior, ruinating behvior and lying behavior were promoted in artificial rearing calves in single pens. Tongue-rolling was especially Promoted in fattening cattle with tethers. Para tongue-rolling in fattening cattle emerged soon after tethering and became gradually stereotypic tongue-rolling. Tongue-rolling decreased in the last stage of fattening. Performance of tongue-rolling suppressed frustrated behaviors, that is, autogrooming and ruminating. Tongue-rolling performers tended to be animals not suffering internal lesions. In addition, the number of tongue-rolling performers tended to increase with carcass grades. These results suggested that tongue-rolling has a suppression effect for psychological stress under behavioral restriction. Investigating behavior, moving behavior, social behavior and reproductive behavior in relation to laying were suppressed in caged hens. It was thought that pecking behavior without getting feed and abnormal behaviors increased in corresponding to these behavioral restrictions. Less
