摘 要: 本实验旨在研究断尾以及添加玩具对仔猪行为、生产性能和血液指标的影响。试验采用哺乳期是否断尾及断奶后是否添加玩具的2×2双因子试验设计,探讨添加玩具缓解断奶仔猪咬尾情况的可能性。结果表明:不断尾组仔猪在哺乳期21日龄时的咬仔猪尾频率显著高于断尾组(P<0.05);此外,断尾会显著减少断奶仔猪排泄行为,降低红细胞平均体积,升高血液白细胞数和血小板数(P<0.05)。添加玩具可以显著增加断奶仔猪探究行为,减少争斗、咬癖和嬉戏行为(P<0.05),显著降低血液平均红细胞血红蛋白浓度和血糖水平(P<0.05)。与单纯断尾相比,不断尾并添加玩具可以显著降低仔猪争斗和咬癖行为,增加探究行为(P<0.05)。因此,不断尾并添加玩具完全可以在不造成断尾应激的基础上有效减少咬尾。 The study was conducted to investigate the effect of tail docking and toys on piglets' behavior, growth gerformance and blood parameters. In this study, a 2x2 two factorial design was adopted between tail docking and toys, to explore the possibility of adding toys to ease the tail biting situation in weaning piglets. As a result, piglets in no docking group shows significantly higher tail biting behavior than that in docking group before weaning (P〈0.05). Tail docking significantly reduces excreting behavior of weaning piglets and MCV in blood, increase WBC and PLT in blood (P〈 0.05). Toys adding significantly increase exploring behavior, and reduce aggressive, biting and playing behavior in weaning piglets (P〈0.05). Serum GLU and blood MCHC were also significantly reduced in toys adding group (P〈 0.05). Compared with simply docking group, no docking but with toys adding significantly reduce aggressive and biting behavior, increase exploring behavior (P〈0.05). Therefore, Toys with no docking can effectively reduce tail biting without causing tail docking stress.
