Main ingredients
Vitamin A, Vitamin D3, Narcisside, Guanylacetic acid, etc.
Mechanism of action
The action mechanism of Narcisside is to block the protein synthesis of bacteria. It inhibits bacteria at low concentration and kills bacteria at high concentration. Narcisside inhibits the growth of harmful intestinal bacteria and makes intestinal wall absorption function normal, thus promoting animal growth and improving feed utilization rate.

Product characteristics
1. Low dosage and can effectively promote the growth of livestock and poultry and improve the utilization of feed;
2. It mainly inhibits the growth of Gram-positive bacteria.
3. There is no cross-resistance with other antibiotics.
4. It has little impact on the environment and belongs to the environmental protection type.
Safety evaluation
1. Drug resistance: Narcisside is not easy to produce resistance caused by R-plasmid, and there is no cross-resistance with other antibiotics.
2. Residual: Narcisside is not absorbed by digestive tract, so it is not residue in animals.
3. Environmental impact: the half life of the discharged narcecin in pigs and chicken manure was 1 and 20 days respectively. The feces containing narcecin were used as fertilizer for plants and no residues were found in fruits. Therefore, it can be considered that Narcisside has little impact on the environment.
4. Toxicity: The toxicity of natriuretic peptide is very low.
Applied experiments on pigs
Nasopeptide can significantly promote the growth of pigs, improve the feed conversion rate, and effectively prevent and control piglets and sows necrotizing enteritis, improve the survival rate of piglets and sows reproductive rate.

Table 1: the production performance of different growing Dun three yuan crossbred pigs. The addition of 2.5 10mg/kg Na of CP peptide has obvious growth promoting effect on pigs, and pigs are bright and ruddy.

The piglets were treated with 5 mg/kg natriuretic peptide, 15 mg/kg amiramycin and 20 mg/kg virginiamycin combined with colistin sulfate (20 mg/kg) for 36 days. The results showed that the daily gain of Narcisside group was the highest, 4.5% higher than that of Amilamycin group (P > 0.05), 13.4% higher than that of Virginiamycin group (P < 0.05), followed by that of Amilamycin group and 8.5% higher than that of Virginiamycin group (P > 0.05).

In 2006, 102 adult dualistic castrated boars were randomly divided into 5 groups. The control group was fed with a diet of 24mg/kg oregano oil. The results showed that the production performance and economic benefits of each antibiotic group were better than those of oregano oil group. The nacetin group and the kitamycin group had the fastest growth rate and lower feed cost, while the nacetin group had the lowest feed cost and higher daily gain. Amilamycin and kitamycin have higher daily gain and feed conversion rate, but because of the high feed unit price, the feed cost is relatively high. Because of the low daily intake, the weight gain rate in the group of getamycin was slower than that of other antibiotics, and the time to go out was longer than that in the group of other antibiotics.
