Effects Of Chinese Herbs On Wuding Chicken Growth Performance And Immune Properties

In our study,0-day Yunnan Wuding300chicks were randomly divided into fivegroups, each60, each equipped with three replicates, each group of20, and then set up thetest group Ⅰ (basal diet+respectively0.2%compound Chinese herbal medicine), groupⅡ (basal diet+0.4%compound Chinese herbal medicine), group Ⅲ (+0.6%compoundherbal-based day-old), the antibiotic group (basal diet+chlortetracycline) and controlgroup (base diet), the entire administration of the same concentration. Feeding trials inYunnan Agricultural University experimental farm Academy of Sciences, taken captivebreeding, and water ad libitum, sheds light constant temperature heating off temperaturemode, the temperature during the first week off temperature of34~36℃, humidity65%-70%; the first two weeks of30~33℃, humidity of60-65%, a week after the fall3℃,humidity maintained at about60%, five weeks later renamed reared under naturalenvironmental conditions. Immune disinfection during the test developed by the routineimmunization program carried out under the same environmental groups are raising49days. The experiment to study the effect of compound herbal feed additives on wudingchicken growth performance and immune function, but also for the partial or totalreplacement of alternative antibiotics as animal growth promoters and animal immuneenhancer to provide a theoretical basis. The results showed that:1. Under the experimental conditions add Chinese medicine preparation in dietsWuding chicken can effectively improve the growth performance, Compound herbaladditives added in the amount of0.4%for0-49days wuding chicks only average weight,average daily gain, feed intake, feed conversion ratio has a significant role in promoting,one average weight, average daily gain of6.11%, respectively, compared to improve antibiotic group,3.69%, up8.72%, respectively, compared with the blank control group,6.57%, the difference was significant (P <0.05); mortality rate3.33%respectively,compared with the antibiotic group and the control group5%, the difference wassignificant (P <0.05);2.Chinese herbal compound in the amount of0.4%added, to promote thedevelopment of intestinal villi morphology plays a significant role in intestinal villi height160.64,168.81(μm) than the antibiotic group and the control group, the difference wassignificant (P <0.05); hidden nest depth but no significant difference (P>0.05) than theantibiotic group and the control group shallow; intestinal villus height and crypt depth ratiowas significantly higher than the antibiotic group and control group, respectively, higherthan27.80%,33.05%;3.Chinese herbal compound added in the amount of0.4%, thymus index ratio and theantibiotic group and the control group were105.88%higher,112.12%, the difference wassignificant (P <0.05);66.67%higher than the spleen index antibiotic group and controlgroup,66.67%, was not significant (P>0.05); bursa Index70.00%higher than theantibiotic group and the control group,142.85%, the difference was significant (P <0.05);4.Chinese herbal compound0.2%,0.4%of the amount added, can significantlyimprove the various age stages wuding strong chicks Newcastle disease, avian influenzaantibody titers, and extend the peak of the antibody, the antibody titer35days ofantibiotics ND2.58higher titers3.08higher than the control group titer. Significantdifferences (P <0.05),49-day antibiotic group ND antibody titer titer higher than1.25,higher than the control group,1.75titers, the difference was significant (P <0.05);35daysAI antibody titers price drops with antibiotics group and control group, respectively, highertiter1.56,2.24, significant difference (P <0.05).49days AI antibody titer higher than2.18in the control group titer higher titers than the antibiotic group1.15, significant difference(P <0.05);5. Chinese herbal compound in0.4%dose, effectively increasing the age of each stagewuding strong chicks dissolved in serum enzymes, thereby increasing the level of immunechicks.6.When the addition amount of0.4%compound Chinese herbal medicine, cansignificantly improve the serum total protein and albumin levels, and effectively reduce thelevels of serum urea nitrogen, prompting the body to strengthen the protein metabolism and amino acid utilization increased, improving the body physiology and biochemistryprocess, thus contributing to the growth of the fast-growing chicks; significantly improvedthe C3, C4and immunoglobulins IgG, IgM, IgA levels in serum complement, therebyincreasing the level of humoral immunity chicks.7.Chinese herbal compound in0.2%,0.4%dose, significantly increased the red, whiteblood leukocytes and lymphocytes in the proportion effectively enhance the immunefunction of chicks.In summary, the results demonstrated the good performances of our compoundChinese medicine additive in improving the growth and immunity of Wudingzhuangchicken, whereas optimal effects were observed with the additional dose of0.4%.
