Which represents 9% of the total GHG emissions produced by animal production.\r\n\r\nIn addition, pig production is considered to contribute greatly to the acidification and eutrophication of the environment due to nitrogen (N) and phosphorus (P) emissions resulting from the storage and use of slurry in crop fields.\r\n\r\nIn some European countries, concern about these emissions is as relevant to their environmental agenda as <strong>concern about GHG emissions, <\/strong>since, for example, <span style=\"color: #333333;\"><span style=\"color: #aabcf2;\"><strong>pig and poultry production are responsible for 83% of NH3 emissions into the atmosphere in the EU.<\/strong><\/span><\/span>\r\n\r\nTraditionally, improvements in pig husbandry and management have been aimed at increasing the systems&#8217; effectiveness, especially in regards to the efficient use of\u00a0 resources such as feed.\r\n\r\n<strong>\u21c0<\/strong><strong> Genetic improvement<\/strong>\r\n\r\nFor example, genetic selection has aimed <strong>to:<\/strong>\r\n\r\nIncrease growth rate\r\n\r\nImprove carcass features, such as improving lean performance\r\n\r\nImprove the reproductive performance of sows\r\n\r\n<strong>\u21c0<\/strong><strong> Feed and nutritional improvement\u00a0<\/strong>\r\n\r\nImprovements in the <strong>use of feed<\/strong> have also contributed to this, for example by:\r\n\r\nThe use of exogenous enzymes and synthetic amino acids\r\n\r\nAdvances in feed manufacturing technology\r\n\r\nAny <strong>improvement in resource use efficiency will also improve the environmental impact of these systems.<\/strong>\r\n\r\nThis is because feed associated activities, including slurry management, are responsible for most GHG emissions in pig and other livestock systems. In the case of pigs, it represents more than 70% of the impact of these production systems.\r\n\r\n<strong>Emissions associated with feed production<\/strong> are particularly high if the <em>Agricultural Land Use Change (ALU<\/em>) is taken into account. Involving deforestation linked to<a href=\"https:\/\/nutrinews.com\/en\/europes-soybean-crops-rise-with-climate-change-as-a-potential-ally\/\"> soybean production<\/a> for example. Which was the main source of protein for feeding pigs until recently.\r\n\r\n<strong>Enteric methane emissions in pig production are negligible, but methane and nitrous oxide emissions from slurry are more noticeable.<\/strong>\r\n\r\nGiven this association between food-related activities and the environmental impact of pig production systems, it is not surprising that the production phase which con\r\n\r\ntributes the most to the environmental impact is that of the <strong>fattening stage. Due to the fact that it is the phase where feed consumption is higher and feed utilization efficiency is lower.<\/strong>\r\n\r\nNaturally, the opposite occurs in the <strong>transition phase<\/strong>, especially in the case of early weaning piglets whose<strong> environmental impact is minimal<\/strong>.\r\n\r\nTaking all of the above into account, we have recently estimated <strong>the evolution of the environmental impact of pig production systems<\/strong> in Great Britain over the last 20 years.\r\n\r\nGiven that almost <strong>50% of sows in the UK are raised outdoors<\/strong>, both conventional (intensive) systems and outdoor (extensive) production systems were considered.","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":{"_acf_changed":false,"footnotes":""},"categories":[128,130],"tags":[],"canales":[236],"Idioma":[15],"intereses":[330],"participantes":[],"acf":{"link_podcast1":"https:\/\/images.socialagri.com\/agriFM\/wp-content\/uploads\/2022\/06\/17165356\/Enviromental-impact-reduction-capacity-by-pig-production.mp3","imagen_podcast1":"https:\/\/nutrinews.com\/wp-content\/uploads\/2022\/03\/cabezal-cerdo.png"},"yoast_head":"<!--
