摘要

背景:刚出生的仔猪会立即为建立乳头秩序而争斗。在这一过程中,仔猪的脸部和母猪的乳头上会出现病变,这就是为什么德国的许多猪场都要进行牙齿切除术,尽管人们知道这种手术经常会导致牙髓洞开。牙髓腔开口被怀疑会导致牙齿疼痛,并可能成为传染源的入口。本研究的目的是分析切除牙齿对乳猪皮肤损伤、体重发育和行为的影响。产前四天,110 头从产仔到分娩的母猪被分配到三种处理中的一种。仔猪的牙齿保持原样(对照组,CG),用茶杯滚轴磨头(茶杯磨头组,TCG,Wilofa Diamant,D-56,133 Fachbach,德国)或用金刚石滚轴磨头(滚轴磨头组,RG,IBS/E Company Proxxon GmbH,54,343 Föhren,德国)。对 RG 和 TCG 的果肉开口数量进行了随机抽样检测。在仔猪出生后 24 小时内和哺乳期的每一周内记录仔猪体重和皮肤损伤评分。在产仔前、哺乳期第二周和断奶时,对每头母猪的乳房进行检查。在整个哺乳期,对九头母猪产下的仔猪的行为进行了录像。本研究旨在探讨用茶杯头磨牙(与用金刚石滚轮头磨牙和不磨牙[对照组]相比)对仔猪行为和平均日增重以及母猪乳房皮肤损伤的影响:结果:RG 组的牙齿损伤数量明显多于 TCG 组(p 结论:RG 组的牙齿损伤数量明显多于 TCG 组:由于磨牙经常会导致牙髓损伤,因此应仔细、严格地审查该手术的必要性。如果在潜在的管理问题得到解决之前,牙齿切除似乎不可避免,则应使用茶杯磨头,因为其牙髓开口明显较少。

Effects of different tooth grinding procedures on the occurrence of tooth injuries, skin lesions, performance and behaviour of suckling piglets.

Background: Immediately after birth, newborn piglets fight to establish a teat order. During this process, lesions appear on the piglets' faces and on the sows' teats, which is why tooth resection is carried out on many farms in Germany even though it is known that this procedure is frequently resulting in pulp openings. The opening of a pulp cave is suspected to cause painful tooth alterations and may be an entrance for infectious agents. The purpose of this study was to analyse the effect of tooth resection on skin lesions, development of bodyweight and behaviour in suckling piglets. Four days prepartum, 110 sows in farrow-to-finish production were assigned to one of three treatments. Litters had their teeth left intact (control group, CG), ground with a tea-cup roller head (Tea-cup head grinder group, TCG, Wilofa Diamant, D-56,133 Fachbach, Germany) or ground with a diamond rolling head (rolling head grinder group, RG, IBS/E Company Proxxon GmbH, 54,343 Föhren, Germany). The number of pulp openings in the RG and TCG was examined using a random sample. Piglet body weight and skin lesion scores were recorded within the first 24 h after birth and during each week of the suckling period. Each sow's udder was examined before farrowing, in the second week of lactation and at weaning. The behaviour of the litters from nine sows was video-recorded throughout the suckling period. The aim of this study was to investigate the effects of tooth grinding by a tea-cup head (compared to grinding by a diamond roller head and no grinding [control group]) on the behaviour and average daily gain of piglets as well as on skin lesions on sow udder.

Results: The number of dental injuries was significantly greater in the RG than in the TCG (p < 0.01). Head lesions on piglets were significantly more common in the CG than in the RG (p = 0. 02). Compared to CG piglets, TCG piglets had a significantly greater weight at the end of the suckling period (p = 0.02). No significant difference between treatments was found in the sows' udder (parenchyma, skin, or teat) or in the behaviour of the litters.

Conclusion: As tooth grinding is frequently inducing pulp openings, the necessity of the procedure should be carefully and critically scrutinised. In case tooth resection seems inevitable until the underlying management problems have been solved, the Tea-cup grinding head should be used due to significantly fewer pulp openings.
