Eucommia ulmoides leaves is a natural Chinese herbal medicine. In recent years, research has found that the main chemical components of Eucommia ulmoides and Eucommia ulmoides leaves are similar. Eucommia ulmoides extract chlorogenic acid, polysaccharides and flavonoids are the main components of Eucommia ulmoides or Eucommia ulmoides leaf extracts. The three components are the active ingredients of many Chinese patent medicines currently on the market and are increasingly applied to animals. Recent studies have found that Eucommia ulmoides leaf extract has certain effects in improving pork muscle quality; protecting liver and gall, improving pig immunity; and removing free radicals and antioxidant effects in pigs.

Improve pork quality

With the improvement of material living standards, people are paying more and more attention to food quality and health issues. In particular, the incidents of clenbuterol and other harmful additives such as clenbuterol and quinethanol in previous years, as well as the "Fu Xi incident" this year, have made people more skeptical about food safety. Eucommia ulmoides leaf extract, as a pure plant extract, has certain effects in improving pork quality.

 

More and more domestic companies and well-known experts and professors are also realizing this step by step.

 

Wang Jianhui and Professor He Jianhua (Institute of Animal Nutrition, College of Animal Science and Technology, Hunan Agricultural University) and other researchers studied the effects of Eucommia ulmoides extract on carcass quality and amino acid content in muscles. High, but the intramuscular fat content of the treatment group added with flavomycin was significantly lower; in the face of amino acid content, the Eucommia ulmoides extract treatment group can significantly increase the total amino acid and umami amino acid content of pork muscle. This shows that the Eucommia ulmoides extract has a certain promotion effect on improving the quality of pork.

Liver and gallbladder protection, improve pig immunity

 

At present, compared with developed countries, the level of farming in China is still very backward, and in order to increase pork production, a large number of antibiotics have been applied. This is a kind of damage to the pig's body itself; at the same time, the toxic substances released by the germs after the killing cause secondary damage to the pig. The liver protects the pig body. Excessive toxins cause liver disease. Plant extracts have replaced the current trend of antibiotics. Recent research has found that the effects of chlorogenic acid on antibacterial and antiviral effects are significant.

 

Yan Qiuping (Master of Technology, Guangdong University of Technology), in the protection of liver damage by plantain and eucommia ulmoides extract, found that eucommia ulmoides extract has obvious protection against carbon tetrachloride (CCl4) and thioacetamide (TAA) acute liver injury effect.

 

Li Lijing (New Drug Research Center, Affiliated Hospital of Changchun College of Traditional Chinese Medicine), and others found that chlorogenic acid can inhibit the neuraminidase activity of the virus in canine kidney passage cells infected with influenza virus, and can promote Newcastle disease virus (NDV) A network of interferons that induces human whole blood cells. Recent research has also found that chlorogenic acid can activate calcineurin, thereby enhancing macrophage function.

 

Ye Xingshen (Department of Anatomical Group Embryology, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences, Peking Union Medical College) and others also reported that chlorogenic acid can effectively inhibit endothelin and nitric oxide (NO) secreted by intestinal mucosal microvascular endothelial cells. The increased ratio has a protective effect on the function of intestinal mucosal microvascular endothelial cells under the action of endotoxin. In addition, chlorogenic acid can also inhibit the production of cytokines and chemokines caused by staphylococcal exotoxin.

 

Wang Xuebing (College of Animal Husbandry and Medical Engineering, Henan Agricultural University, lecturer) reported that chlorogenic acid can inhibit and block porcine parvovirus and porcine reproductive and respiratory syndrome (commonly known as blue ear disease). Within a safe concentration range, chlorogenic acid has a significant inhibitory and blocking effect on PRRsV in vitro, and its minimum inhibitory concentration on Porcine Reproductive and Respiratory Syndrome Virus is 0.39 lµg / ml, and its minimum blocking concentration is 0.0977µg / ml; the minimum inhibitory concentration against porcine parvovirus is 1.56 µg / ml, and the minimum blocking concentration against porcine parvovirus is 0.391 µg / ml.

 

Scavenging free radicals and antioxidant effects

 

95% of the oxygen inhaled by the animal body supplies cells with energy, and 2% -5% becomes DPPH free radicals (1,1-diphenyl-2 pietylhydrazyl), hydroxyl free radicals, and superoxide anion free radicals. Intrinsic potential stressors; on the other hand, various stress factors (environment, feed, drinking water, pathogens, epidemic prevention, etc.) can cause the body to produce excessive free radicals. The presence of a large amount of free radicals is not good for animal health. When Yan Qiuping was studying liver damage, she found that excessive free radicals caused various oxidation reactions of various substances (lipids, carbohydrates, proteins, DNA and other macromolecular substances) constituting cell tissues. Causes oxidative damage such as cross-linking, degeneration, and rupture, which in turn destroys cell structure and function, causing body damage and organ disease.

 Eucommia Leaf Extract

Studies at home and abroad show that chlorogenic acid is an effective phenolic antioxidant, and its antioxidant capacity is stronger than that of caffeic acid, parabens, ferulic acid, and syringic acid, as well as common antioxidants, such as butyl hydroxyl Anisyl ether (BHA) and tocopherol.

 

Wu Chun (Professor, School of Food Engineering, Harbin Commercial University) found that eucommia flavonoids had significant antioxidant activity against lard during the test. Adding a mass fraction of 0.30% eucommia flavonoids could make the shelf life of lard at 20 ℃ from 2.5 Months extended to 8.1 months.

 

In short, Eucommia ulmoides leaf extract can replace the use of some antibiotics in actual production and reduce the development of animal resistance. Eucommia ulmoides leaf extract has no effect on the daily feed intake of animals, but it can improve the quality of pork, remove free radicals, improve animal immunity, and protect the liver and gallbladder.
