Effect of Eucommia Leaf Extract on Pork Quality

A large number of researches and applications have shown that Eucommia Leaf Extract, as a feed additive for pigs, can not only significantly improve the growth performance of pigs and increase the economic benefits of farming, but also increase the leanness and remove fat of the pig body; pork nutrition, health care, safety, and muscle colour, aroma and flavour have been significantly improved. Therefore, as a natural green feed additive, Eucommia Leaf Extract is popular among farmers and consumers.

Advantages of Eucommia Leaf Extract as Feed Additive

1. Herbs are ecological and natural, non-toxic, not easy to cause drug resistance, no harmful drug residues, pollution-free, multi-functional, rich in nutrients needed by the animal body, and can be used as green feed additives for pigs.

2. Herbal additives can replace many chemical feed additives and prevent harmful and toxic substances from remaining in meat.

3. Chinese herbal medicine as feed additives can make the harmful microorganisms, odour gas, parasites and other harmful substances in animal faeces greatly reduced or eliminated, and reduce the sewage discharge is conducive to environmental protection.

Mechanism of Eucommia Leaf Extract

1. Broad-Spectrum Antibacterial Effect

Chlorogenic acid, flavonoids and other comprehensive effects on a variety of bacteria with significant inhibition, in vitro bacteriostatic test results show that the lowest inhibitory concentration of Staphylococcus aureus, Streptococcus b is 0.0625g/ml; the lowest inhibitory concentration of Escherichia coli, typhoid fever bacteria are 0.5g/ml and 0.25g/ml respectively, the mechanism of action of the non-competitive inhibition of bacterial arylamine acetyltransferase, thus making the bacterial body arylamine accumulation, so that the bacterial metabolism is disturbed. Arylamine acetyltransferase in bacteria, which leads to a large accumulation of arylamine in bacteria, and the metabolism of bacteria is disturbed, so that bacteria can not grow and reproduce normally.

2. Antioxidant and Free Radical Scavenging Effect

Studies at home and abroad have shown that chlorogenic acid is an effective phenolic antioxidant, and its antioxidant capacity is stronger than that of caffeic acid, p-hydroxybenzoic acid, ferulic acid and butyric acid, as well as common antioxidants, such as butylhydroxyanisole (BHA) and tocopherol, but is comparable to the antioxidant capacity of butylhydroxytoluene (BHT). Chlorogenic acid has an o-diphenol hydroxyl structure, which can increase the electron cloud density on the hydroxyl group, and can also form intramolecular hydrogen bonds, thus lowering the bond energy of O-H, making it easy for hydrogen seizure reactions to occur on the phenolic hydroxyl group, and therefore has strong antioxidant capacity.

Chlorogenic acid is a typical class of compounds with free radical scavenging effects, which can form hydrogen radicals with antioxidant effects to eliminate the activity of free radicals such as hydroxyl radicals and superoxide anions, thus protecting tissues from oxidative damage.

3. Hepatoprotective and Bile-Protective Effect

Animal experiments show that chlorogenic acid has a significant protective effect on carbon tetrachloride (CCl4), acetaminophen and cadmium-induced liver injury, significantly reduce the severity of pathological damage to the liver, so that the total number of hepatic punctate necrosis and necrotic changes in the emergence of the rate of a significant reduction.

Mechanism: First, through the inhibition of cytochrome P-450 pharmacophore metabolism system, inducing hepatic glucuronide binding enzyme activity, enhancement of acetaminophen glucuronide binding metabolism, thereby strengthening the detoxification metabolism of acetaminophen in vivo, reducing the toxic metabolites of acetaminophen and achieve; second, inducing the liver to synthesize a large number of metal mercapto proteins (MT), MT can be a large number of cadmium binding, reducing cadmium in the nucleus, mitochondria, mitochondria and the distribution of cadmium in macromolecular proteins in the cell plasma, thus reducing the toxicity of cadmium to hepatocytes; thirdly, it can promote the secretion of bile and accelerate the discharge of toxins.

4. Stimulate Gastrointestinal Digestive System

Significantly increase gastrointestinal peristalsis and promote gastric juice, secretion and other pharmacological effects, can improve the digestion and absorption of nutrients in livestock and poultry, improve the utilisation of nutrients, so as to promote the growth of livestock and poultry and improve production performance.
