Leaf extract DU ZHONG YE TI QU WANG?? Improve immunity, relieve immunosuppression;?? Broad-spectrum antibacterial, antiviral;?? Promote animal growth, improve feed utilization;?? Sedative sedative, anti-stress , stable production performance. One, Eucommia hormone (leaf extract) Introduction Eucommia hormone is a natural plant extract, is examined and approved by the Ministry of Agriculture production and use of feed additives, new products, the main component of chlorogenic acid, Eucommia flavonoids, polysaccharides and other biologically active substances Eucommia, Product features are: (1) natural plant extracts, without any chemical synthetic substances. (2) active ingredient clear function determines the active ingredients can quantization control. (3) regulation of the immune system induced by interferon, promote antibody production, immune suppression release, improving vaccine potency. (4) broad-spectrum antibacterial, antiviral, immune suppression against livestock diseases, respiratory and gastrointestinal diseases have a good preventive effect. (5) to promote the growth of bifidobacteria and lactobacillus, value-added, regulating animal gut microflora balance, inhibit the growth of bacteria, prevention of gastrointestinal diseases, promote digestion and absorption of nutrients, improve livestock weight gain and survival rate, improve feed utilization. (6) to promote the body's glucose metabolism, accelerate the body's synthesis of proteins and enzymes to promote animal growth. (7) tranquilizer sedative, anti-stress, reduce livestock fence in turn, morbidity, high temperature stress response in case of stable growth performance. Second, the mechanism of immune Eucommia prime the cell surface polysaccharides, flavonoids and other active substances of the receptor through binding to the receptor, increase in the number of immune cells, phagocytic activity is enhanced, and can induce a variety of cytokines (such as interferon, interleukin interleukin, etc.), stimulate its activity increased, play role in immune regulation; adsorption inhibit harmful bacteria to the intestinal wall adhesion and colonization, to maintain normal digestive environment; through antigen-antibody combination, to eliminate reactive oxygen species, antioxidant , plant flavonoids its phenolic hydroxyl group that can react with free radicals, quench free radicals and terminate the chain reaction of free radicals, the animals have significant antioxidant, inhibiting animal peroxidation and antioxidant enzyme activities increased, thus enhancing immune capacity. The active substances of nutritional products to promote healthy intestinal microflora body formation (mainly bifidobacteria and lactobacilli), reduce intestinal PH value, inhibit the growth of disease bacteria while stimulating the digestive tract motility, increasing stool moist and maintain a certain The osmotic pressure, thus preventing disease and treatment of soft stools, constipation and other diseases. Proliferation of beneficial bacteria produce a competitive advantage, reducing the toxic and carcinogenic metabolites produced, so as to maintain, improve animal health; with exogenous pathogenic bacteria and which produces a lectin, to avoid adhesion of the pathogens in the intestine, bacteria adhered truncated - Reproduction - pathogenic infection route and carry pathogens excreted pathogens play erosion, maintain animal health. Third, the test results one, gutta hormone on broiler growth inhibition test. Avilamycin using gutta prime and feed additives with diets comparison test, the test animals Avian broilers. Test result: two additives for broiler production was no significant difference, but the impact on the quality of meat, the former than the latter trend is clearly, slaughter rate was also significantly higher than the latter; and can reduce the use of chemical antibiotics volume, and will help to improve meat quality and improve the slaughter rate. Add Eucommia vegetarian fed hens compared with the control group, extending the time an egg peak times, so that aging laying rate increased more than 28%; eggs decreased total cholesterol by about 24%; chicks die 4-5 days scouring rate from 7% to 1%. Hens feeding test compared with control group decreased by 9%. 2, gutta growth hormone on production performance of fattening pigs. Using gutta hormone additives with Flavomycin fed diets with 300 Duroc pigs for comparison tests. From weaning to breeding 90Kg weight, growing and finishing Chu's daily gain, feed conversion, Mortality two additives were not significantly different, but were significantly higher than the control group. Slaughtered determination proved Add gutta known as help to improve the quality of meat, pigs shoulder fat thickness were lower than flavomycin group and the control group (p <0.05), dressing percentage, lean, muscular hind legs were than flavomycin high 1.83 percent, 2.74 percent, 2.79 percent. Therefore, we can consider factors in addition to completely replace gutta Flavomycin as an additive, but also help improve the quality of meat. 3, tilapia Eucommia hormone on growth performance and improve meat quality tests. Prime and prime enemy using gutta, bacitracin zinc, respectively, with diets on 540 tilapia were reared comparison test. Feeding period 150 days, each tail weight 45-1500g. Eucommia hormone dosage 1500mg/kg, enemy hormone and zinc bacitracin press routine usage. Test Results: Eucommia hormone group relative growth rate than bacitracin zinc group high 2.16%, but no significant difference (p> 0.05), compared with the blank control group and enemy elements were elevated by 29.42% and 19.6%, the difference was significant (p <0.05); FCR, gutta hormone group and bacitracin zinc group had no significant difference (p> 0.05), but significantly higher than the control group (p <0.05); survival, gutta vegetarian group and enemy hormone group 100%, control group and bacitracin zinc group was 98.89%, analysis of variance level no significant difference (p> 0.05). Blood cholesterol levels, gutta hormone group content is lower than the control group, against the enemy hormone group and bacitracin zinc group were lower 53.95%, 5.48%, 37.06%, the difference was significant (p <0.05). Serum globulin, gutta hormone group were higher, enemy hormone group and bacitracin zinc group were higher by 17.14%, 24.58%, 8.9%, but the difference was not statistically significant. However, meat products Eucommia hormone group were significantly better than other groups. The results showed that, gutta prime as tilapia feed additives, combined with improved rearing environment and water quality ponds, can significantly improve the quality of meat. 4, gutta hormone on common fish antibacterial tests. Tests show that the concentration of the solution 0.2g/ml Eucommia prime fish can effectively inhibit intestinal punctate Myxococcus G4 gas unicellular bacteria strains and two yuan 58-20-9,56-12-10 fusants and ternary blend Sub other bacterial growth. So be sure, gutta hormone on freshwater fish common bacterial gill disease, enteritis disease, red skin diseases have a certain role in disease resistance. 5, gutta hormone on shrimp growth and improve meat quality research. Purpose of this study was to explore the South American shrimp gutta hormone on growth and meat quality. Experimental animals vannamei, average weight 1.3g. The same basic formula, the test group to add Eucommia Su: 50 days dosage of 1.5 ‰; 51-90 days dosage of 1.0 ‰; 91-108 days dosage of 0.8 ‰. Experimental results show that adding Eucommia prime feeding shrimp, lower feed conversion rates, improved weight gain; survival rate than the control group 5.66%; shrimp body color bright, succulent fruit, feces brownish Hesse. According to the Hainan Wenchang City, the sun shrimp farms use as an additive shrimp gutta prime test results showed that dietary 0.8 ‰, shrimp grow fast, the average individual specifications, high yield, feed conversion ratio is low, while shrimp body color than Well, stool brownish-black, the survival rate with no significant difference between conventional farming. 6, gutta prime antifungal effect tests. Factors in the development process of Eucommia antifungal effect also conducted trials, participants gutta vegetarian and feed additives include preservatives dew Paul fine salt, mold will grams, with a blank as the control group, after the normal shelf life of 45-60 days, The total number of mold in feed were: Paul Eucommia hormone group exposed group will grams fine salt group mildew control group 1.7 × 105 个 / g 2.3 × 105 个 / g 2.8 × 105 个 / g 5.0 × 105 cells / g extremely significant difference significant (p <0.05). Thus, Eucommia vegetarian diet as a feed additive also has antifungal effect. In addition, the Industrial Research Institute of Hunan Province with gutta hormone on mice with acute, subacute toxin test, the results show that regardless of gutta prime high-dose and low-dose mice of reproductive organs, reproductive function and other physiological parameters had no adverse effects on blood to meet requirements of feed additives. Fourth, promote the use of gutta Su has worked in Beijing, Hebei, Henan, Hunan, Fujian, Hainan, Guangdong, Shandong and other places to promote the application of generally reflect the use of good results. Especially in the longer adding antibiotics and other synthetic drugs feed additives in the case, to add Eucommia vegetarian, feeding effect is very satisfactory performance in the disease has been effectively controlled, significantly improved immunity, animal population health situation improved, especially fish, shrimp , pigs, chickens and other products of meat and flavor improvement effect is very obvious, by the farmers and consumers, have called for continued use as a feed additive gutta prime.
