“…Raising entire male pigs has some economic advantages as boars possess the advantage of superior growth over castrates, a lower feeding demand, generally leaner carcasses, and compared to castrates less feed is needed in order to achieve the same final weight, whereby also fewer nutrients are emitted to the environment (Morlein et al, 2015;Wauters et al, 2017). However, slaughtering entire male pigs implies the risk of having carcasses with the so-called boar taint (Aaslyng, Broge, Brockhoff, & Christensen, 2015) posing a risk to the entire pork supply chain therefore being a significant barrier to the banning of the undesirable practice of piglet castration (Mathur et al, 2012). Boar taint is described as a penetrating 'animal', 'urine', 'faecal' or 'sweat' like unpleasant odour which becomes especially intense when pork is cooked (Mathur et al, 2012), and is mainly associated with the presence of skatole and androstenone, but animal tissues contain varying levels of other compounds, such as indole and other steroids, that can influence the perceptions of the main contributors of boar taint (AnnorFrempong, Nute, Whittington, & Wood, 1997;Morlein et al, 2016).…”
