Embodiment 1

[0020] In order to evaluate the antibacterial effect of compound acidifier and plant extract combination, the diameter of inhibition zone of compound acidifier, plant extract combination and their combination on Escherichia coli and Staphylococcus aureus was determined by Oxford cup method. The compound acidifier is compounded according to the ratio of 15 parts of formic acid, 20 parts of acetic acid, 25 parts of glyceryl butyrate, 15 parts of lactic acid, and 5 parts of ethylenediamine tetraacetic acid; 20 parts of cinnamaldehyde and 10 parts of flavonoids.

[0021] Take 10g of the compound acidulant, 10g of the plant extract and the combination of 10g of the compound acidulant and the plant extract into 100ml of physiological saline, and mix on a magnetic stirrer for 30 minutes. Take Escherichia coli and Staphylococcus aureus cultured slant respectively, wash down the colony with appropriate amount of normal saline, insert it into the sterilized LB medium according to 4%, mi...

Embodiment 2

[0028] The compound acidulant is 15 parts by weight of glyceryl formate, 20 parts of glyceryl acetate, 25 parts of glyceryl butyrate, 15 parts of glyceryl lactate, and 5 parts of ethylenediaminetetraacetic acid; 10 parts of thyme essential oil, 40 parts of boluohui alkaloids, 20 parts of cinnamaldehyde, and 10 parts of flavonoids.

Abstract

The invention provides a combination of a compound acidifier and a plant extract for a feed. The compound acidifier comprises short-chain fatty acid / short-chain fatty glyceride and ethylenediamine tetraacetic acid, wherein the short-chain fatty acid is formic acid, acetic acid, butyric acid and lactic acid, and the plant extract comprises thyme essential oil, macleaya cordata alkaloid, cinnamyl aldehyde and flavones, wherein the weight ratio of the compound acidifier to the plant extract is 20: (2-3). The compound acidifier and the plant extract are combined, so that the combination is healthyand safe, replaces conventional feed antibiotics to be added into broiler feed, and can effectively inhibit reproduction of intestinal pathogenic bacteria, improve intestinal health, improve diseaseresistance of animals, increase average daily gain and reduce the feed consumption weight gain ratio.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a combination of feed compound acidifier and plant extract. Background technique [0002] Antibiotics can improve animal intestinal flora, improve animal immunity, and promote animal growth. The application of antibiotics in livestock and poultry production has brought great impetus to the development of animal husbandry. However, with the widespread use of antibiotics around the world, more and more bacteria are resistant to antibiotics through genetic mutations. At the same time, antibiotic residues in livestock and poultry products threaten human food safety, making the development of antibiotic animal husbandry and An obstacle to the development of food safety, more and more countries around the world ban the use of antibiotics in feed. Under the current circumstances, it is especially necessary to find other safe and effective alternatives to antibiotics to ensure th...
