![]() The number of pairs to be explicitly ranked is minimized by the method identifying all pairs implicitly ranked as corollaries of the explicitly ranked pairs. The method, which we refer to as PAPRIKA (Potentially All Pairwise RanKings of all possible Alternatives), involves the decision-maker pairwise ranking potentially all undominated pairs of all possible alternatives represented by the value model. We present a new method for determining the point values for additive multi-attribute value models with performance categories. Other potential factors included lack of knowledge of negative health consequences associated with short tails, importance placed on dag and flystrike prevention, and impracticality of measuring where to dock.Īddressing these factors in future education and intervention programmes may improve tail docking practice and sheep welfare. Short tail docking appeared to be influenced by unawareness of the recommended length and docking at a length that shearers approve of. In total, 57 per cent of farmers were classed as docking tails short. The focus group data were analysed qualitatively, and the surveys were analysed qualitatively and quantitatively. ![]() Two focus groups, phone (n=30) and online surveys (n=21) were conducted in regional Victoria, Australia to examine farmer knowledge of and attitudes towards appropriate lamb tail length and barriers to best practice. To address this issue, this study aimed to identify key drivers behind tail docking length decisions. However, recent studies have found that some tails are docked too short (24–86 per cent). ![]() To ensure optimal healing after tail docking and reduce the risk of arthritis, perineal cancers and prolapses, it is recommended to dock tails equivalent to the length of the vulva. Tail docking is common practice in the sheep industry to prevent soiling of the breech and flystrike. These preferences did not differ among farmers that dock tails at different lengths or leave them intact. When farm performance characteristics, that may influence decisions relating to tail docking practices, were prioritised by farmers, preferences for minimizing deaths from fly-strike, improving weaning weight and making more money from the processor were greater than having fewer dag events, less euthanasia from rectal prolapses and less stress for the lamb at docking. Farmers who docked lamb tails at a longer length (4-7 cm) gave significantly (P<0.05) more importance to reducing uterine prolapse and to the processor requirements and to minimize fly-strike than to any other reason. Farmers who docked lamb tails to a shorter length (3-4 cm) gave significantly (P<0.05) more importance to minimizing fly-strike, reducing the likelihood of dags and reducing the cost and time of crutching than to any other reason. The main reasons for docking were to minimize fly strike risk, reduce accumulation of dags and keep the crutching costs down. 22%) and docking a greater number of lamb tails at 4-7 cm length (32% vs. Compare to a survey carried out in 2005, New Zealand farmers appear to be docking fewer lamb tails flush (6% vs.
