Embodiment 1

[0016] A total of 300 1-day-old healthy Liuzhou Ma chickens were selected and randomly divided into 3 groups by using a single-factor experiment design. The basal diet and nutrient composition are shown in Table 1. During the whole test period (1-56 days old), 0.3% and 0.6% P1 were added to the basal diet of group A and group B respectively. # (choose 27% of Pulsatillae water extract, 45% of purslane water extract, 12% of Folium Folium water extract, and 16% of Folium verticillium alcohol extract from the suitable proportioning of the present invention, mix and make), in antibiotic The basal diet of the control group was supplemented with 50 mg / kg of flavomycin, free to eat and drink, and follow the routine immunization procedure. Study P1 # Effects of different doses on the survival rate and growth performance of 28-day-old and 56-day-old Liuzhou Ma chickens, and compared with antibiotics.

Embodiment 2

[0025] A total of 300 1-day-old healthy Liuzhou Ma chickens were selected and randomly divided into 3 groups by using a single-factor experiment design. The basal diet and nutrient composition are shown in Table 1. Whole test period (1~49 days old) in the basal ration of A group and B group, add respectively 0.3% and 0.6% P2# (choose 49% of Pulsatillae water extract, purslane oleracea from the suitable ratio of the present invention Water extract 21%, Folium Folium water extract 23%, the proportioning of fennel extract 7%, mix and make), add the flavomycin of 50mg / kg in the basal ration of antibiotic control group, feed ad libitum and drinking water, according to routine immunization procedures. To study the effects of different doses of P2# on the survival rate and growth performance of 21-day-old and 49-day-old Liuzhou Ma chickens, and compare them with antibiotics.

Abstract

The invention discloses a green feed additive which can replace antibiotics in dorking diets and a preparation thereof, and belongs to the technology field of the greed feed additive. The invention are prepared by the steps that 27-49% of Chinese bulbul aqueous extract, 21-45% of purslane aqueous extract, 12-23% of dyers woad leaf aqueous extract, 7-16% of ash bark alcoholic extract are combined according to the compatibility proportion; the mixture is well mixed, crashed, and then passes 100 mesh sieve to be made into additive product. The invention serves as the additive which can completely replace antibiotics in dorking diets on one hand, increase feed intake, strengthen animal health and increase manufacture performance; the additive has no toxicity, side effects, and residue and 'three cause', does not pollute environment, and can provide livestock and poultry with higher quality for human as well as increase economic benefits.

Description

technical field [0001] The invention relates to a green feed additive which can replace chickens, especially antibiotics in broiler rations and a preparation method thereof, belonging to the technical field of green feed additives. Background technique [0002] Feed safety is a major issue of widespread concern in the world today. The long-term use of antibiotics in feed leads to the emergence of drug resistance, endogenous infection and superinfection of livestock and poultry, decreased immunity of livestock and poultry, and residues in livestock and poultry products and the environment. This has also become a global problem. More and more developed countries have begun to restrict or ban feed antibiotics, and my country has also restricted the use of some antibiotics as feed additives in feed. Therefore, the development of new and safe green feed additives to replace or partially replace the application of antibiotics or drugs in the livestock and poultry industry can all...
