The Bacteriostatic Action Of Natural Allicin, And Natural Allicin Affects To Broiler Chickens Production Performance And The Serum Biochemical Indicators And The Growth Hormone

To study natural allicin inhibits bacteria, study of garlicin on growth performance, immune function and serum biochemical indices and growth hormone effects. In test room used Cup disc method detection garlic pigment on Escherichia coli and Golden Staphylococcus of anti bacteria ring, by nutrition meat soup diluted method determination has garlic pigment on Escherichia coli and Golden Staphylococcus of minimum anti bacteria and sterilization concentration, and draws has garlic pigment of anti bacteria curve; in raised poultry field test will 1st age merchandise generation avian meat Tsai chicken 300 only random into 5 a processing group, each processing group 60 only broiler, each processing group set 3 a repeat, each repeat group 20 only meat Tsai chicken. Control group feeding Foundation General tie day grain; garlic pigment ⅰ group feeding Foundation tie day grain+garlic pigment (350mg·kg-1); garlic pigment ⅱ group feeding Foundation tie day grain+garlic pigment (500mg·kg-1); garlic pigment ⅲ group feeding Foundation tie day grain+garlic pigment (650mg·kg-1); chlortetracycline contrasts feeding Foundation tie day grain+ chlortetracycline (500 mg·kg-1). Study on effect of garlic on growth performance of broiler chickens, and further in the immune function and serum biochemical indices and growth hormone effects.Antimicrobial test results showed that study on antibacterial action of garlicin pathogenic bacteria are Staphylococcus aureus, Escherichia coli, on the antibacterial effect of Staphylococcus aureus than Escherichia coli, on the antimicrobial activity of two kinds of pathogenic bacteria are better than tetracycline. Effect of garlicin on much better ability to inhibition of Staphylococcus aureus bacteria Escherichia coli, MIC and MBC on Staphylococcus aureus 0.06g/ml; MIC and MBC on Escherichia coli are the 0.03g/ml, garlic than tetracycline on sterilization of Escherichia coli and Staphylococcus aureus fastest, kill works best.Garlicin on broiler performance test results indicate that allicin average daily gain than control groups increase 5.39%(p<0.05), average daily intake of garlic group than the control group increased 0.97%(p<0.05), garlic group to the misery of the control group average was lower than 4.27%(p<0.05); Overall incidence of allicin group than the control group lowered 55.94%; garlic reduces the total mortality rate than the control group of the Group of 55.6%. Broiler diet 500mg/kg weight gain effect of allicin and the economic benefits of the most obvious.Effects of garlic on serum immune organ of broilers affect test results show that after application of allicin 21d, allicin control group on average index of indices, disease of the spleen, thymus indices increased,12.75%,12.21%, respectively, the difference is not significant (p>0.05). Effect of allicin on development of immune organ of broilers effects are better than the control group, and the effect of aureomycin group.Garlicin on intestinal Escherichia coli in broiler chickens and test results showed that the effect of lactic acid bacteria number, allicin group to broiler intestinal Escherichia coli than the control group declined by 8.46%, and aureomycin group than the control group anti effect significantly (p<0.05); after garlic 21d, no significant inhibition of Lactobacillus (p>0.05).Garlic pigment on meat Tsai chicken serum biochemical test results indicates that, garlic pigment group total protein content average than control group total protein content high has 7.07%(p> 0.05); garlic pigment Group white protein content than control group content high has 5.65%(p> 0.05); garlic pigment group globulin content average than control group globulin content high has 5.78%(p> 0.05); garlic pigment group urea nitrogen content average than control group urea nitrogen content reduced has 3.42%(p> 0.05). Allicin and aureomycin on broiler serum glucose, serum triglyceride and total cholesterol no significant effect. Garlic pigment group than control group blood glucose content reduced has 1.91%(p> 0.05), than chlortetracycline group blood glucose content reduced has 1.77%(p> 0.05); garlic pigment group than control group and the chlortetracycline serum glycerol three ester content are reduced has 2.08%(p> 0.05); garlic pigment group serum total cholesterol content average than control group serum total cholesterol content reduced has 2.65%(p> 0.05).Garlicin on meat chicken growth hormones affect the test results show that garlic glands of the original 1-methyl group of three iodine (T3) content than the control group average increase an average of 10.09%(p< 0.05); allicin set of four original 1-methyl iodide gland (T4) 24.71% higher than the control group on average, significant difference (p< 0.05); Garlic group growth hormone (GH) 4.24% lower content than the control group on average, lower than that of chlortetracycline Group 1.83%; on insulin-like growth factor-I (IGF-I) garlic group the content of 3.03% lower than the control group on average, lower than that of chlortetracycline group 0.33%, the difference is not significant (p> 0.05).By the above test results show that garlic has a role of inhibition and killing pathogens, while chicken has a significant role in weight gain and disease prevention, at the same time there is a clear economic benefits, clinical application of allicin can replace antibiotics, reduction of drug residues, clinical recommendations in accordance with the dietary 500mg/kg supplementation in broilers.
