This is incorporated herein by reference.
技术领域Technical field
本发明实施例涉及猪饲料技术领域，尤其涉及一种提高猪肉脂肪中不饱合脂肪酸含量的猪饲料。The embodiments of the invention relate to the field of pig feed technology, and in particular to a pig feed for improving the content of unsaturated fatty acids in pork fat.
背景技术Background technique
不饱和脂肪酸对人体的生理功能有巨大作用，如：1.保持细胞膜的相对流动性，以保证细胞的正常生理功能；2.使胆固醇酯化，降低血中胆固醇和甘油三酯；3.是合成人体内前列腺素和凝血恶烷的前躯物质；4.降低血液粘稠度，改善血液微循环；5.提高脑细胞的活性，增强记忆力和思维能力。尤其是 -3系列不饱和脂肪酸：二十二碳六烯酸(DHA)、二十碳五烯酸(EPA)作用更大。自上世纪90年代以来，DHA一直是儿童营养品的一大焦点。英国脑营养研究所克罗夫特教授和日本著名营养学家奥由占美教授最早揭示了DHA的奥秘。他们的研究结果表明：DHA是人的大脑发育、成长的重要组成物质之一。EPA具有帮助降低胆固醇和甘油三酯的含量，促进体内饱和脂肪酸代谢的作用。从而降低血液粘稠度，增进血液循环，提高组织供氧而消除疲劳，防止脂肪在血管壁的沉积，预防动脉粥样硬化的形成和发展、预防脑血栓、脑溢血、高血压等心血管疾病。Unsaturated fatty acids have great effects on the physiological functions of the human body, such as: 1. Maintaining the relative fluidity of the cell membrane to ensure the normal physiological function of the cells; 2. Esterifying cholesterol and lowering blood cholesterol and triglycerides; Synthesize human prostaglandins and prostaglandin prosthetic substances; 4. Reduce blood viscosity, improve blood microcirculation; 5. Improve brain cell activity, enhance memory and thinking ability. In particular, the -3 series of unsaturated fatty acids: docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have a greater effect. DHA has been a major focus of child nutrition since the 1990s. Prof. Croft and the famous Japanese nutritionist Professor Ou Zhanmei first revealed the mystery of DHA. Their results show that DHA is one of the important components of human brain development and growth. EPA helps reduce cholesterol and triglyceride levels and promotes the metabolism of saturated fatty acids in the body. Thereby reducing blood viscosity, improving blood circulation, improving tissue oxygen supply and eliminating fatigue, preventing deposition of fat in the blood vessel wall, preventing the formation and development of atherosclerosis, preventing cardiovascular diseases such as cerebral thrombosis, cerebral hemorrhage and hypertension.
绝大多数不饱和脂肪酸,尤其是 -3系列不饱和脂肪酸不能在人体内转化形成，只能靠外部饮食摄入。Most of the unsaturated fatty acids, especially the -3 series of unsaturated fatty acids, cannot be transformed in the human body and can only be consumed by external diets.
猪肉作为主要的食材，通过食用，人体可以摄入猪肉中所含有的成分。研究如何促进猪肉脂肪中不饱和脂肪酸的含量，尤其是ω-3系列不饱和脂肪酸中的二十二碳六烯酸(DHA)和二十碳五烯酸(EPA)的含量，从而可以更好的通过食用猪肉来增加人体所需的DHA和EPA，促进人体健康是一个很重要的课题。As a main ingredient, pork can be eaten and the body can take in the ingredients contained in pork. Study how to promote the content of unsaturated fatty acids in pork fat, especially the content of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in omega-3 unsaturated fatty acids, which can be better It is an important issue to promote human health by eating pork to increase DHA and EPA required by the human body.
发明内容Summary of the invention

采用每头猪单独饲养，每头猪每天分3次(早、中、晚)自由饲喂完全饲料，共计每天3kg，按上述进食量，持续饲养45天。12个组分别各喂一种饲料，每组内10头猪喂相同的饲料，形成11个实验组和一个对照组，实验组1至实验组11的饲料中二十碳五烯酸含量依次为：0.05‰、0.15‰、0.25‰、0.3‰、0.4‰、0.5‰、0.6‰、0.9‰、1‰、1.1‰、1.2‰。Each pig was individually raised, and each pig was fed three times a day (early, medium, and late) with a total of 3 kg per day, and the feeding was continued for 45 days. Each of the 12 groups was fed a feed, and 10 pigs in each group were fed the same feed to form 11 experimental groups and a control group. The content of eicosapentaenoic acid in the feed of experimental group 1 to experimental group 11 was : 0.05‰, 0.15‰, 0.25‰, 0.3‰, 0.4‰, 0.5‰, 0.6‰, 0.9‰, 1‰, 1.1‰, 1.2‰.
在饲养的第45天，进行宰杀，每组的每头猪均选取猪肉里脊、后腿、腹部皮下脂肪三个部位的样品，进行脂肪酸成分分析，获得脂肪中不饱和脂肪酸的含量，并对每组中三个部位的各个样品的不饱和脂肪酸含量取平均数。获得12种不同二十碳五烯酸含量的猪饲料饲养的猪的三个部位的脂肪中不饱和脂肪酸的含量，具体数据见表2-1、表2-2、表2-3。 On the 45th day of breeding, slaughter was carried out. Each pig in each group was selected from three parts of pork loin, hind legs and abdominal subcutaneous fat to analyze the fatty acid composition to obtain the content of unsaturated fatty acids in fat. The average fatty acid content of each sample at three locations in the group was averaged. The content of unsaturated fatty acids in the fat of the three parts of the pigs fed the pig feed with 12 different eicosapentaenoic acid contents is shown in Table 2-1, Table 2-2 and Table 2-3.

由表2-1、2-2、2-3可见，饲料中添加含二十碳五烯酸的微藻后，猪肉三个部分的脂肪中不饱和脂肪酸均得到很大提高。饲料中添加不同含量的二十碳五烯酸，猪肉里脊部分的脂肪中含有的DHA、EPA可以得到较大的提高；饲料中添加0.4‰、0.5‰、0.6‰的二十碳五烯酸，后腿、腹部皮下脂肪的脂肪中的DHA、EPA有了很大提高；饲料中添加0.9‰、1‰、1.1‰的二十碳五烯酸，后腿、腹部皮下脂肪的脂肪中的DHA、EPA提高量最大；饲料中添加1.2‰的二十碳五烯酸，后腿、腹部皮下脂肪的脂肪中的DHA、EPA提高量相对饲料中增加的二十碳五烯酸变化不大，考虑到微藻成本非常高，没有必要在饲料中无限制的增加微藻来提高二十碳五烯酸的含量。It can be seen from Tables 2-1, 2-2, and 2-3 that after the microalgae containing eicosapentaenoic acid is added to the feed, the fatty acids in the three parts of the pork are greatly improved. Adding different levels of eicosapentaenoic acid to the feed, the DHA and EPA contained in the fat of the pork loin can be greatly improved; adding 0.4‰, 0.5‰, 0.6‰ of eicosapentaenoic acid to the feed, DHA and EPA in the fat of the lower leg and abdominal subcutaneous fat have been greatly improved; the feed contains 0.9‰, 1‰, 1.1‰ of eicosapentaenoic acid, DHA in the fat of the hind legs and abdominal subcutaneous fat, The EPA increased the most; the addition of 1.2 ‰ eicosapentaenoic acid to the feed, the increase in DHA and EPA in the fat of the hind leg and abdominal subcutaneous fat did not change much compared with the increased eicosapentaenoic acid in the feed, considering The cost of microalgae is very high, and there is no need to increase microalgae in the feed without restriction to increase the content of eicosapentaenoic acid.
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。 The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention.
