The invention discloses a method for preparing an anti-duck viral hepatitis transfer factor, which comprises the following steps of: firstly, inoculating duck viral hepatitis in a chick embryo allantoic cavity for multiplication and extracting a virus antigen from the chick embryo allantoic cavity; secondly, immunizing a healthy pig body with the extracted virus antigen; and thirdly, extracting the anti-duck viral hepatitis transfer factor from the spleen of the immune pig. In the invention, specific transfer factor is extracted from duck viral hepatitis viruses and can effectively suppress the duck viral hepatitis viruses and protect the cells of a normal body from being infected with the duck viral hepatitis viruses, so that the duck viral hepatitis is prevented and treated radically. Moreover, the preparation method of the invention is simple and feasible, short in production time and low in cost and has a promising application prospect.

The invention discloses a method for refining chicken egg yolk antibodies against Escherichia coli, which comprises the following steps of: culturing by adopting formaldehyde, thiomersalate and a white oil adjuvant to prepare antigen solution; immunizing healthy chickens by using the antigen solution, and collecting immune eggs; extracting egg yolk antibodies from the immune eggs; and purifying by adopting ammonium sulfate to obtain the chicken egg yolk antibodies against the Escherichia coli. For the chicken egg yolk antibodies against the Escherichia coli, pili are collected first, and then Escherichia coli antibodies in the chicken egg yolk are collected after organism immunization of chickens, wherein when the Escherichia coli antibodies in the chicken egg yolk are collected, ammonium sulfate solution is adopted for purification. Experiments prove that the potency of the chicken egg yolk antibodies against the Escherichia coli is obviously improved.

The invention relates to a method for preparing thymosin. The method comprises the following steps of: washing thymosin clean with a buffer solution with the pH of 3.5-4.0, then adding the buffer solution with the pH of 3.5-4.0 and homogenizing at low temperature to prepare a thymosin homogenate solution; carrying out thermotropy centrifugation on the obtained homogenate solution to remove protein impurities; then regulating the pH value of a supernatant to 4.5-5 with hydrochloric acid; centrifuging once again, and regulating the pH of the supernatant to be neutral; filtering the obtained neutral supernatant by using different filter membranes to remove impurities and bacteria; and freeze-drying to obtain a finished thymosin product. The method has the advantages of improving the activity and the yield of the thymosin and reducing the production cost.
