Research The Applications Of Traditional Chinese Medicine In Avian Broiler

As a feed additive for broiler trial,the "Qi Ling 1 ", "Qi Ling 2 " and "anticoccidial Chinese medicine" were used to study the influence for broiler production,antioxidant activity,immune function,blood biochemical indexes,digestive enzymes activity. Two thousands 1-day broilers were randomly divided into the negative control group, the positive control group, Chinese medicine1,2,3 groups, with 4 replications per group and 100 broilers per replication. Negative control group was fed the basal diet,the positive control group was fed the basal diet with 30ppm zinc bacitracin and 6ppm Colistin Sulphate,Chinese medicine1,2,3groups were fed the basal diet with"Qi Ling 1"from first week to third week(Doses were 1.4g/L,2.8g/L,2.8g/L,by drinking water),and with"Qi Ling 2"from forth week to slaughter(Doses were 0.8g/L,1.5g/L,1.5g/L,by drinking water),Chinese medicine 3 group was fed by anticoccidial Chinese medicine in the whole process. The results showed that: The "Qi Ling 1 ", "Qi Ling 2 "could reduce feed conversion ratio of broilers,the dressing percentage eviscerated rate,breast muscle rate and leg muscle rate of the Chinese medicine group 2 and group 3 were higher than the negative control group,the difference were significant (P<0.05). SOD activity of Chinese medicine group 1,2,3 were significantly higher than the negative control group (P<0.01);the total antioxidant capacity of Chinese medicine group 2 and group 3 were significantly higher than the negative group and positive control group (P<0.01);the MDA of Chinese medicine group 3 was significantly lower than the negative control group and the positive control group(P<0.01). The IgA,IgG,C3,ALT,albumin and total protein levels of Chinese medicine group 2 and group 3 were higher than the negative control group (P<0.05). Serum lysozyme activity of Chinese medicine group 1,2,3 and the positive control group were significantly higher than the negative control group (P<0.01). The amylase activity of Chinese medicine group 1 was significantly higher than the negative control group (P<0.01), the intestinal contents amylase activity of Chinese medicine group 3 was significantly higher than the negative control group and positive control group (P<0.01). The small intestine lipase activity of Chinese medicine group 1,2,3 and positive control group were significantly higher than the negative control group (P<0.01). The protease activity from intestinal contents of Chinese medicine group 1 and group 3 were significantly higher than the positive control group (P<0.01).The high dose "Qi Ling 1 ", "Qi Ling 2 " could increase the production of broiler performance and slaughter performance, reduce production costs and improve immunity of broilers.Two hundred and sixteen 1-day broilers were randomly divided into blank group, infection without drug group, sodium sulfa chlorpromazine group, low, medium and high dose Chinese medicine group, with 3 replications per group and 12 broilers per replication. Except the blank group, the other groups were infected 8×10~4 coccidia oocysts by mouth, and were fed anticoccidial drugs by drinking water on the fifteenth day. Blank group and infection without drug group were fed basal diet, sodium sulfa chlorpromazine group was fed sulfonamide sodium soluble powder chlorpromazine 1.0 g/L by drinking water, low, medium and high dose Chinese medicine group were fed anticoccidial Chinese medicine 0.8g/L,1.2g/L,1.6g/L. The "Anticoccidial Chinese medicine" was used to study the influence of survival rate, relative growth rate, disease value, oocysts values, anti-coccidiosis cecal lesion score and the pathology of the cecum. The results showed: in the four dose groups, the anticoccidial index of high dose group was 180.13, the anticoccidial index of sulfa chlorpromazine group was 181.06, this showed that high dose Chinese medicine and the sulfa chlorpromazine were sensitive to coccidiosis; the survival rate of Chinese medicine high-dose group reached to 97.22%, and its relative growth rate was 90.41%, this showed that the Chinese medicine had a strong effect against coccidiosis; the ACI values of low dose groupand middle dose group were 170.67and 166.11, both of them had reached to the level of coccidia-sensitive,and also had moderate level of resistance to coccidiosis. Anticoccidial Chinese medicine composited with Radix Dichroae, RootofChneseThorowax, Anemone chinensis,Uncaria macrophylla Wall, Agrimonia eupatoria, Radix Sanguisorbae, had the effect for anticoccidial. The high doses anticoccidial Chinese medicine had the same effect for anticoccidial as the sodium sulfa chlorpromaze.
