Problems solved by technology

The inventor has carried out many years of research on the feed development of natural biologically active substances, and found that as a feed additive, due to the production to application (animals feed into the body) to go through storage, transportation, secondary processing (mixed with other feed ingredients to produce complete In this link, it may experience many links such as granulation, puffing and other high-temperature and harsh environments), and it takes a long time, so it is not suitable to use volatile ingredients, such as essential oils, because the uncontrollable loss of active ingredients will make the product The functional components are not constant, affecting the uniform expression of the effect

Embodiment 1

[0068] Embodiment 1: the application of triterpenoid saponins as a feed additive meets general formula I:

[0069] The extraction method is as follows: take a certain amount of plant material known to contain triterpenoid saponins of general formula I, extract 3 times with ethanol (60-95%, volume ratio) at normal temperature, mix the extracts and dry to obtain For triterpenoid saponins, the drying process can be spray drying or vacuum drying.

[0070] The known plant material that takes by weighing 4800 grams contains the triterpenoid saponin of general formula I, wherein R 2 = H; R 3 for CH 3 ; 1 for H. Extracted 3 times with ethanol (95%, volume ratio) at normal temperature, mixed the extracts and spray-dried to obtain 380 grams of triterpenoid saponins. Animal tests were carried out with the extracted triterpenoid saponins.

Embodiment 2

[0071] Embodiment 2: take a certain amount of plant material known to contain triterpenoid saponins of general formula I, wherein R 2 =glc;R 3 for CH 3 ; 1 for -glcUA.

Embodiment 3

[0072] Embodiment 3: take a certain amount of plant material known to contain triterpenoid saponins of general formula I, wherein R 2 =

[0073] -glc - glc;R 3 for CH 3 ;R1 is -glcUA 3 -ara.

Abstract

The present invention is the application of triterpenoid saponin as feed additive. Triterpenoid saponin is prepared through thrice alcohol extraction at normal temperature and the drying of the extracted liquid with the drying process being ether spray drying or vacuum drying. The present invention makes it possible to eliminate the residue of antiseptic in animal product, produce high-quality pollution-less animal product, and raise animal survival rate and feed utilization.

Description

technical field [0001] The invention relates to the use of triterpene saponins, in particular to the use in the field of feed additives. Background technique [0002] With the large-scale and intensive development of the modern breeding industry, a large number of antibiotics (substances with antimicrobial effects derived from microbial fermentation and chemical synthesis, the same below) are used as feed additives to prevent and control livestock and poultry diseases and promote animal growth and development . At present, there are more than 60 types of antibiotics used as feed additives in the world, and about 20 types are approved for use in my country. The application of antibiotics in feed has made a great contribution to the rapid growth of the aquaculture industry and to meet the human demand for animal food. The long-term use of antibiotics in the feed has more and more negative effects: (1) Drug resistance: Adding antibiotics in low doses in the feed for a long ti...
