Embodiment 1

[0033] A feed additive for preventing and treating colibacillosis in chickens is prepared from the following raw materials in parts by weight: 30 parts of volatile oil clathrate of camphor leaves, 1 part of composite probiotic microcapsule, 3 parts of yeast extract, 0.1 part of mold agent.

[0034] Wherein, the clathrate of camphor leaf volatile oil is composed of camphor leaf volatile oil and a carrier at a weight ratio of 1:4, and the carrier is β-cyclodextrin. The β-cyclodextrin is preferably hydroxypropyl-β-cyclodextrin. The composite probiotic microcapsules are composed of composite probiotics and wall materials at a weight ratio of 1:0.5. The compound probiotics are a mixture of Bacillus, Bifidobacterium, Lactobacillus rhamnosus and Lactobacillus acidophilus in a weight ratio of 2:1:2:1. The wall material is a mixture of hydroxypropylmethylcellulose, chitosan and sodium alginate. The antifungal agent is sodium diacetate.

Abstract

The invention discloses a feed additive for preventing and treating chicken colibacillosis and a preparation method thereof, and belongs to the field of livestock and poultry feeds, and the feed additive comprises the following components in parts by weight: 30-45 parts of a cinnamomum longepaniculatum leaf volatile oil clathrate compound, 1.0-1.5 parts of compound probiotic microcapsules, 3-5 parts of a yeast extract and 0.1-0.5 part of a mildew preventive. The preparation method of the feed additive comprises the following steps: dropwise adding extracted cinnamomum longepaniculatum leaf volatile oil into a beta-cyclodextrin solution to prepare a cinnamomum longepaniculatum leaf volatile oil clathrate compound; mixing the compound probiotics, and then obtaining the compound probiotic microcapsules through an embedding technology; and mixing the prepared cinnamomum longepaniculatum leaf volatile oil clathrate compound, the compound probiotic microcapsules, a yeast extract and a mildew preventive in proportion. The feed additive provided by the invention not only can prevent and treat chicken colibacillosis, but also has the characteristics of low residue, no pollution, difficult generation of drug resistance and the like, and also can reduce the morbidity of chickens and improve the survival rate of adult chickens, thereby realizing healthy and green breeding.

Description

technical field [0001] The invention relates to the field of livestock and poultry feed, in particular to a feed additive for preventing and treating chicken colibacillosis and a preparation method thereof. Background technique [0002] chicken colibacillosis ( colibacillosis ) is a group of infectious diseases caused by pathogenic Escherichia coli. Grayish-white iris, vision loss or blindness, loose feathers, feces sticking to feathers around anus, green or yellowish-white loose feces, crouching, inability to stand, reluctance to move or limp, joint enlargement, hepatomegaly, intestinal Mucosa bleeding and ulcers, pericardial inflammation, ascites and yolk accumulation in the abdominal cavity, the death rate is usually 5%-20%, and can reach 50% in severe cases. The measures taken by the current farmers are intramuscular injection of American Rips E. coli Kang or the use of oxytetracycline, norfloxacin, enrofloxacin, thiamphenicol, gentamicin and other drugs as feed additi...
