Example Embodiment

[0015] Implementation example 1

[0016] 300 1-day-old healthy Liuzhou chickens were selected, using a single factor test design, and randomly divided into 3 groups. See Table 1 for basal diets and nutritional components. During the entire trial period (1 to 56 days old), 0.3% and 0.6% of P1 were added to the basal diets of group A and group B, respectively # (From the suitable ratio of the present invention, select 27% of the water extract of Pulsatilla, 45% of the water extract of Portulaca oleracea, 12% of the water extract of Daqingye, 16% of the alcohol extract of Qin bark, and mix them to make), The basal diet of the control group was supplemented with 50 mg / kg of flavomycin, and the diet and water were ad libitum, and the routine immunization procedures were followed. Study P1 # The effects of different doses on the survival rate and growth performance of 28-day-old and 56-day-old Liuzhou chickens were compared with antibiotics.

[0025] 300 1-day-old healthy Liuzhou chickens were selected, using a single factor test design, and randomly divided into 3 groups. See Table 1 for basal diets and nutritional components. During the entire test period (1~49 days old), 0.3% and 0.6% of P2# were added to the basal diets of group A and group B respectively (selected from the suitable ratio of the present invention, 49% of Pulsatilla water extract, Portulaca oleracea Water extract 21%, Daqingye water extract 23%, Qin bark alcohol extract 7%, mixed together), add 50mg / kg of flavomycin to the basal diet of antibiotic control group, free intake And drinking water, according to routine immunization procedures. To study the effect of different doses of P2# on the survival rate and growth performance of 21-day and 49-day-old Liuzhou 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...
