Abstract

BACKGROUND

Working dog handlers and breeders have very different behavioural requirements in the animals that they employ for managing livestock. The Australian Working Kelpie breed may be used in several working contexts, notably yards, paddocks and a combination of both. The working context influences the skillsets required and gives rise to three corresponding work-types: and Kelpies. In particular, dogs used for working stock in the confines of yards and trucks interact with stock more forcefully than those mustering in larger areas (paddocks) where they can herd stock effectively from a greater distance. This article explores owner assessments of dog working quality and assessment of genomic similarity by multidimensional scaling, to ask whether it is sufficient for breeders to aim for a multipurpose breeding objective, or whether breeding only specialist lines maximises user satisfaction for yard and paddock work.

RESULTS

Reported owner perceptions of 298 dogs assessed with the Livestock Herding Dog assessment tool showed that dog handlers across all working types were very happy with their dogs' level of general skills.Compared with both and Kelpies, Kelpies had significantly lower trait scores for (pressure applied by the dog to move livestock), willingness to the stock (run along a sheep's dorsum) and (frequency of using the mouth to grab or bite the livestock). Meanwhile, compared with both Paddock and Kelpies, the Kelpies had significantly higher scores for hyperactivity and excitability (both with and without stock) and impulsiveness without stock. As one would predict for all-rounders, Kelpies had intermediate scores for all behaviours and working traits.

CONCLUSIONS

Specialist characteristics were displayed by dogs in the Kelpie and Kelpie groups. In particular, Kelpies demonstrate higher excitability, willingness to the stock, and a higher tendency to and the stock. Conversely, Kelpies rarely display these characteristics. Kelpies, as the name suggests, are intermediate between the other two groups and display the characteristics of both. Genetic analysis suggests that the Yard, Utility and Paddock Kelpies are not distinguishable at a DNA level. In conclusion, at this time there is no suggestion of a breed split in the Australian Working Kelpie generated by selection for work type. A common breeding objective should enable dogs to be produced that fulfil all potential working requirements. This reinforces the importance of breeder skill in recognising the phenotypic potential of pups in order to place them in appropriate working contexts.

摘要

背景

工作犬的训导员和饲养员对他们用于管理牲畜的动物有着截然不同的行为要求。澳大利亚工作凯尔皮犬种可用于多种工作场景,尤其是围场、牧场以及两者结合的场景。工作场景会影响所需的技能组合,并产生三种相应的工作类型:以及凯尔皮犬。特别是,在围场和卡车范围内用于管理牲畜的犬只与牲畜的互动比在较大区域(牧场)放牧的犬只更加强烈,在牧场中它们可以从更远的距离有效地驱赶牲畜。本文通过多维尺度分析探讨了主人对犬只工作质量的评估以及基因组相似性评估,以询问饲养者以多用途繁殖目标为导向是否足够,或者仅培育专门品种是否能使围场和牧场工作的用户满意度最大化。

结果

使用畜牧犬评估工具对298只犬进行评估后,主人报告的看法显示,所有工作类型的犬只训导员对他们犬只的总体技能水平都非常满意。与和凯尔皮犬相比,凯尔皮犬在(犬只驱赶牲畜时施加的压力)、驱赶牲畜的意愿(沿着羊的背部奔跑)和(用嘴抓取或咬牲畜的频率)方面的特征得分显著较低。同时,与牧场凯尔皮犬和凯尔皮犬相比,凯尔皮犬在多动和易兴奋(有牲畜和无牲畜时)以及无牲畜时的冲动性方面得分显著更高。正如人们对全能犬的预期,凯尔皮犬在所有行为和工作特征方面得分居中。

结论

凯尔皮犬组和凯尔皮犬组的犬只表现出专门特征。特别是,凯尔皮犬表现出更高的兴奋性、驱赶牲畜的心甘情愿程度以及更高的驱赶和咬牲畜倾向。相反,凯尔皮犬很少表现出这些特征。凯尔皮犬,顾名思义,介于其他两组之间,兼具两者的特征。基因分析表明,围场凯尔皮犬、通用凯尔皮犬和牧场凯尔皮犬在DNA水平上无法区分。总之,目前没有迹象表明澳大利亚工作凯尔皮犬因工作类型选择而出现品种分化。一个共同的繁殖目标应能培育出满足所有潜在工作要求的犬只。这强化了饲养者技能在识别幼犬表型潜力以便将它们置于适当工作场景中的重要性。
