This study is rare in that it includes\u00a0females, castrates, Improvest\u00ae treated males and\u00a0intact males from the same litters, all tested under\u00a0similar conditions. These comparisons provide\u00a0valuable information on differences that can be\u00a0expected for both producers and packers to plan\u00a0for and make decisions related to options for\u00a0control of boar taint.\u00a0\u00a0This study confirmed the advantages of raising\u00a0intact males in terms of growth performance\u00a0compared to females and castrates. Improvest\u00ae\u00a0treatment is an interesting option because it gives\u00a0the benefit of improved growth performance of\u00a0intact males while producing carcasses of similar\u00a0composition to castrates.\u00a0\u00a0Genetic selection based on specific genetic\u00a0markers shows potential for producing intact males\u00a0with naturally low enough levels of androstenone\u00a0and skatole to avoid boar taint problems.<\/p>\n<p>However,\u00a0more research is needed on genetic evaluation\u00a0methods, consideration of influence of genetics\u00a0from the maternal breeds and to incorporate\u00a0newly identified genetic markers. The impact of\u00a0management and environment also needs to\u00a0be considered as large differences in the levels\u00a0of boar taint were observed between trials.\u00a0 The\u00a0combination of management and genetics could\u00a0result in lower and lower probability of carcasses\u00a0from intact males having boar taint.\u00a0\u00a0A new technology based on DNA aptamers\u00a0shows great promise to lead to a reliable, practical\u00a0and affordable screening test for boar taint. This\u00a0could be in the form of a simple kit similar to a\u00a0home pregnancy test available for humans. The\u00a0ability to screen for boar taint combined with\u00a0genetic selection to lower the frequency of intact\u00a0males that have boar taint problems could lead to\u00a0a viable alternative for control of boar taint.<\/p>\n<p><a href=\"http:\/\/prairieswine.com\/rsc\/wp-content\/uploads\/2018\/07\/Control-and-Detection-of-Boar-Taint-CCSI.pdf\">Control and Detection of Boar Taint CCSI<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author:\u00a0 Brian Sullivan, Brianna Sullivan\u00a0and Laurence Maignel &#8211;\u00a0Canadian Centre for Swine\u00a0Improvement Reference:\u00a0 Centred on Swine.
