Effect Of Chinese Traditional Medicine Additive On Health Of Organic Broiler And Soil Environment

This experiment was conducted to study the effects of Chinese medicine additives on organic broiler health and soil environment. Four kinds of Chinese medicine additives were used.And there were six treatment groups in the research,which concluded four experiment groups using different Chinese medicine additives and two control groups (organic breeding group without any addictives and conventional breeding group with biotic). In addition, some broiler manure in every group was put into soil to be cultivated under invariable temperature for detect soil respiration and E. coil content, which studied the effect of Chinese traditional medicine additive on health of organic broiler and soil environment. The main results were as follows:(1) Chinese Medicine additive 'C' and additive containing earthworm peptide can enhance the broiler weight and reduce the ratio of feed and weight during the intermediate and prophase growth phase. In the age of 17-50, the weights of broiler using these additives increased12.64%(p<0.05),3.75%(p>0.05) respectively, and the daily weight increase 29.53%(p<0.01), 13.75%(p<0.01) respectively, which make the ratio of feed and weight reduce by 18.85%(p<0.01).(2) The effect of Chinese medicine on the slaughter performance of organic broiler was no significant (p>0.05).(3) Additive containing earthworm peptide could improve the content of amino acids in the broiler. And Chinese medicine additive 'C' could prolong chicken fresh preservation period (p>0.05). All the flesh color of broilers in organic breeding was deeper than that of normal chicken (p<0.01). Both the total content of amino acid and the 16 amino acids content in the chicken using additive containing earthworm peptide were higher than that in other group.(4) The disease resistant ability was decreased in all the groups using Chinese medicine additive during the growth prophase of organic broiler. But in middle and late phase of broiler growth, the disease resistant ability in medicine additive 'C' was no difference compared to the control. While the groups containing medicine additive 'B' or earthworm peptide increased the eliminating ratio of broiler though there was on significant effect statistically. And the broiler feeding medicine additive 'C' increased eliminating ratio by 10.71-19.28 % (p<0.01).(5) The amount of broiler intestinal microorganism no varied in Chinese medicine additive 'C' group than that in other groups. The additive of earthworm peptide reduced the reproductive performance of Escherichia coli (E.coli )(p<0.01) in the growth prophase; While in the growth mid-phase and anaphase, promoted reproductive performance of E.coli (p<0.05) and depressed that of lactobacillus (p<0.01); The additive of medicine additive 'B' had no difference on the count of E.coli (p>0.05), while reduced significantly the lactobacillus reproduce (p<0.01); In addition, in Chinese medicine additive 'A' group,the amount of E.coli increased (p<0.05) and the amount of lactobacillus reduced (p<0.01).(6) No matter how much the basic content of E.coli was in the poultry manure, the last E.coli content would keep the dynamic balance in the soil applied above poultry manure. But the soil respiration would be enhanced 34.15 times after using organic broiler manure. Effect of broiler manure using different Chinese medicine additive on the soil respiration was different, and the effect of manure using Chinese medicine additive 'C on soil respiration was the lowest (p<0.05) among the experiment groups. However, Chinese medicine additive 'C could influence the soil respiration most strongly in the experiment groups when applied into soil directly with feed use level.Overall, the results indicated that traditional Chinese medicine additives, applied in the organic breeding of broiler, could improve their growth performance and meat quality. But the study of Chinese medicine additives on resistant disease ability will be further developed. In addition, the organic breeding with Chinese medicine additives, similar to conventional breeding, would affect the soil microorganism.
