This is due to the fact that laying hens find themselves in a unique physiological state and are<strong> more likely to suffer from lipid metabolism disorders<\/strong>.\r\n<p style=\"padding-left: 40px\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-110988\" src=\"https:\/\/nutrinews.com\/wp-content\/uploads\/2022\/07\/item.jpg\" alt=\"\" width=\"22\" height=\"19\" \/>Therefore, the type of oil to be included as well as its appropriate proportion are particularly<strong> important for the productive performance, lipid metabolism and egg quality<\/strong> of laying hens.<\/p>\r\n<p style=\"padding-left: 40px\">The lipids found in the egg yolk are mainly derived from dietary oils and therefore these play a crucial role in laying hens&#8217; productive performance and egg quality.<\/p>\r\nThe main types of oils used in laying hen diets are from plant and animal origin.\r\n\r\nVegetable<span style=\"color: #339966\"><strong> oils<\/strong><\/span> commonly used in poultry feed are<strong> rich in unsaturated fatty acids (UFAs). These are<\/strong> <strong>important for the growth and development<\/strong> of laying hens. This is especially true for linolenic acid and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Linoleic_acid\" target=\"_blank\" rel=\"noopener\">linoleic acid<\/a>, which are essential fatty acids (EFAs).\r\n\r\n&nbsp;\r\n\r\nLinolenic acid deficiency hinders development and reduces production yield, while linoleic acid is deposited directly into the egg yolk and thus increases the weight of the egg through an increase in yolk weight(<em>Kostik et al.<\/em> , 2015). [register]\r\n\r\nSome of the most common vegetable oils used in feed are: <strong>soybean, rapeseed, palm and flaxseed oil.<\/strong>\r\n\r\n&nbsp;\r\n\r\n<span style=\"color: #ff0000\"><strong>Animal oils<\/strong><\/span> (mainly triglycerides (TG)) are extracted from animal fat tissue.When included in diets, these fats <strong>increase the UFA content of eggs<\/strong> (<em>O&#8217;Brien<\/em>, 2008; \u00a0<em>Kralik et al.<\/em> , 2021).\r\n\r\nAnimal <u>oils <\/u>which are commonly used in feed mainly include <strong>lard, poultry fat, tallow, and fish oil<\/strong>.\r\n\r\nIn general, these oils contain more saturated fatty acids (SFA) than vegetable oils <em>(Wang et al.,<\/em> 2015).\r\n\r\nThe inclusion of oils to laying hen diets has become an effective method for:\r\n<ul>\r\n \t<li><strong>Promoting animal growth<\/strong><\/li>\r\n \t<li><strong>Increasing conversion rates<\/strong><\/li>\r\n \t<li><strong>Improving the health of
