Eucommia ulmoides leaf extract is a green feed additive extracted from natural raw materials of eucommia ulmoides leaf. It has various functions in broiler chickens, such as improving growth performance and meat quality. I. Improve the growth performance of broiler chickens: The Poultry Research Institute of Shandong Academy of Agricultural Sciences conducted an experiment on improving the growth performance of broiler chickens with Eucommia leaf extract (Xingfu 100): Randomize 1,200 1-day-old healthy AA+ broilers Divided into 4 groups, each group has 3 repetitions, each repetition is 100, and the feeding period is 1-48 days old. Observe the effects of Xingfu 100, bacitracin zinc and flavomycin on broiler performance. The results show that the addition of 150g/t Xingfu 100 to the broiler diet can significantly improve the performance of broilers. Compared with the control group, Xingfu 100, bacitracin zinc and flavomycin can significantly improve the performance of broilers; Compared with zinc and flavomycin, Xingfu 100 has the best effect in improving broiler performance in terms of various indicators such as final weight, daily gain and feed-to-meat ratio. Second, scavenging free radicals, anti-lipid peroxidation, and improving meat quality: Eucommia natural active substances can significantly promote the synthesis and metabolism of collagen protein, and improve the quality and flavor of livestock and poultry meat. Muscle fibers are delicate, muscle fat content is reduced, higher uns Phenibut on sale aturated fatty acid content is more, and sweet and fragrant compounds are increased. So it looks tender and delicious. Lin Shimei et al. (2003) researched that the total amino acid content of the breast muscle of broilers fed with Eucommia leaves was higher than that of broilers not fed with Eucommia ulmoides. Among them, amino acids (aspartic acid, glutamic acid, phenylalanine, leucine The content of acid, valine, serine, histidine, methionine and isoleucine) is higher than that of broiler chickens not fed with Eucommia. These amino acids that affect the flavor of meat are the material basis for the delicious meat after feeding Eucommia ulmoides. Studies have shown that the chlorogenic acid in Eucommia leaves plays a major role in scavenging free radicals, anti-lipid peroxidation, and improving meat quality. Researches at home and abroad show that chlorogenic acid is an effective phenolic antioxidant, and its antioxidant capacity is stronger than caffeic acid, paraben, ferulic acid and syringic acid, as well as common antioxidants. Oxidizing agents such as butyl hydroxyanisole (BHA) and tocopherol. The mechanism of action is that chlorogenic acid has an ortho-diphenolic hydroxyl structure, which can increase the electron cloud density on the hydroxyl group and form intramolecular hydrogen bonds, thereby reducing the bond energy of OH, making the hydrogen abstraction reaction on the phenolic hydroxyl group p China Phenibut rone to occur , So it has strong antioxidant capacity. Three, antibacterial and antiviral, instead of antibiotics: chlorogenic acid, flavonoids and other comprehensive effects, have a significant inhibitory effect on a variety of bacteria, the in vitro antibacterial test results show that, against Staphylococcus aureus, The minimum inhibitory concentration of Streptococcus b is 0.0625g/ml; the minimum inhibitory concentration for Escherichia coli and Typhoid bacillus are 0.5g/ml and 0.25g/ml, respectively. The mechanism of action is non-competitive inhibition of aryl groups in bacteria. Amine acetyltransferase, which causes a large accumulation of aryl amines in the bacteria, disturbs the metabolism of the bacteria, and prevents the bacteria from growing and reproducing normally. The experiment of the Poultry Research Institute of Shandong Academy of Agricultural Sciences: 150ppm Xingfu 100 in the early stage (0-21 days of age), 120ppm Xingfu 100 in the middle stage (22-36 days of age), and 100ppm Xingfu 100 in the late stage (37-42 days of age). With probiotics, antibiotics in the feed are eliminated. The results show that the replacement of antibacterial drugs in the broiler chickens does not affect the growth performance of the broilers. Four. Repair liver damage: Animal experiments show that chlorogenic acid has a significant protective effect on liver damage caused by carbon tetrachloride (CCl4), acetamino Phenibut Manufacturers phen and cadmium, and significantly reduces liver pathological damage Severity, the number of spot necrosis of the liver and the occurrence rate of necrosis are significantly reduced. Mechanism of action: First, by inhibiting the cytochrome P-450 drug enzyme metabolism system, inducing liver glucuronic acid binding enzyme activity, enhancing acetaminophen glucuronic acid binding metabolism, thereby enhancing the detoxification metabolism of acetaminophen in the body and reducing acetaminophen The second is to induce the liver to synthesize a large amount of metal sulfhydryl protein (MT). MT can bind to cadmium in a large amount, reducing the distribution of cadmium in the nucleus, mitochondria, microsomes and macromolecular proteins in the cytoplasm, thereby reducing the effect of cadmium on The toxicity of liver cells; third, it can promote the secretion of bile and accelerate the discharge of toxins. 5. Maintain the balance of intestinal flora, reduce diarrhea and diarrhea, and increase the survival rate of broilers. Eucommia ulmoides leaf extract has pharmacological effects such as significantly increasing gastrointestinal motility and promoting gastric juice secretion, which can improve the digestion and absorption of nutrients by livestock and poultry, and increase the utilization of nutrients, thereby promoting the growth of livestock and poultry and improving production performance. Eucommia polysaccharides can be used as food for beneficial bacteria in the intestines (such as bifidobacteria, lactobacilli), change the microbial flora in the digestive tract, and increase the proliferation of beneficial bacteria in the intestinal tract.
