Problems solved by technology

In particular, bird flu is a devastating disease, and it is a zoonotic disease, which is extremely harmful. For example, the bird flu suffered by some Asian countries in early 2003 caused a great blow to the economies of these countries and favored the death of many people due to infection of the disease. At present, there is no effective prevention and treatment drug for this, so immunization prevention is very important. Usually, inoculation of avian influenza virus (AIV) oil emulsion vaccine is used for immunization, but the AIV antigen has diversity, and the antigenicity between each

Example Embodiment

[0065] Example 1

[0066] Culture substrate preparation: Take 100g of astragalus residue, 200g corn cob, 500g yam residue, and 300g bran to prepare a holistic substrate; inoculate 100g of Huaier fungus in the holistic substrate; adjust the fermentation temperature to 25±3℃ and the water content to 60% , Fermented for 35 days; collect the medicinal fungal substance, dry at 60°C, and crush to obtain the feed additive.

[0067] Add the obtained feed additives according to the weight percentage of 1% of the normal full-price ration of AA broilers, and mix them to obtain the feed for preventing bird flu.

Example Embodiment

[0068] Example 2

[0069] Culture substrate preparation: Take 100g of astragalus residue, 150g corn cob, 500g yam residue, and 250g bran to prepare a holistic substrate; inoculate 50g of Hericium erinaceus in the holistic substrate; adjust the fermentation temperature to 25±3℃ and the water content to 55% , Fermented for 40 days; collected medicinal fungal substance, dried and crushed at 70°C.

[0070] Add the obtained feed additives according to the weight percentage of 1% of the normal full-price ration of AA broilers, and mix them to obtain the feed for preventing bird flu.

Example Embodiment

[0071] Example 3

[0072] Culture substrate preparation: Take 150g of astragalus residue, 150g corn cob, 350g yam residue, and 350g bran to prepare a holistic substrate; inoculate 100g of Ganoderma lucidum in the holistic substrate; adjust the fermentation temperature to 28±3℃ and the water content to 45%. Fermentation for 25 days; the medicinal fungal substance is collected, dried at 50°C and crushed.

[0073] The obtained feed additive is added according to the weight percentage of 2% of the normal full-price ration of AA broilers, and mixed uniformly to obtain feed that enhances the body's immunity.

Abstract

The invention discloses a feed addictive with its preparing technology and application in producing feedstuff on anti- bird's flu. By means of inoculating medicinal fungus into all character base material comprised of drug character base material and nutritional base material, adjusting fermentation conditions, it will gain the feed addictive collecting drug character fungus after fermentation spanning some time. This feed addictive can enhance animals' immunity and used to produce feedstuff on anti- bird's flu. The equipment has simple technique, low coat and be green and environmental protection.

Description

technical field [0001] The invention belongs to the field of feed additives, and relates to a novel feed additive developed by using medicinal fungus two-way solid fermentation engineering technology. The invention also relates to the preparation process of the feed additive and its application in the manufacture of feed for preventing bird flu. Background technique [0002] At present, there is no clinically effective drug for the treatment of viral diseases in animals, mainly relying on adding some antibiotics to animal diets to prevent the occurrence of diseases, and long-term use of antibiotics may lead to the occurrence and transfer of bacterial resistance and cause Drug residues in livestock and poultry products; and affect human health and destroy ecological balance through the food chain, so many countries prohibit or restrict the application of antibiotics in feed. Since 1999, the European Union only allowed 4 kinds of antibiotics to be used in feed, and my country ...
