Embodiment Construction

[0007] An example is described in detail below: the selected Asteraceae Artemisia sativa is processed according to the treatment method of Chinese medicinal materials, dried in the shade and pulverized into a coarse powder, and 50 g is packed into a 1000 ml retort, and extracted by heating, condensing and reflux with 55% ethanol Three times, adding 400ml of ethanol each time, extracting for 2 hours at a temperature of 95°C, combining the three extracts, and recovering ethanol. The three extracts were mixed and then dried into powder by microwave for animal use. For a dairy cow with a milk yield of 20kg, calculated on the basis of a feed-to-milk ratio of 1:2.5, its daily concentrate feed intake is 8kg, and the daily dosage of the ethanol extract of A.

Abstract

The invention discloses a preparation method of an artemisia ordosica feed additive, which is mainly characterized by comprising the following steps of: drying the whole artemisia ordosica plant in the shade; then, crashing the whole artemisia ordosica plant into coarse powder; extracting active ingredients by using ethanol with a refluxing extraction method; and drying the active ingredients into powder by microwaves to obtain the artemisia ordosica feed additive. The modern biotechnology is adopted in the preparation method according to a traditional Chinese medicine principle, and the extracts are dried into the artemisia ordosica feed additive by microwaves. Because the feverfew artemisia ordosica has wide sources, the invention has an operable function of finally producing CLA (Conjugated Linoleic Acid) by using artemisia ordosica extracts as plant extracts.

Description

technical field [0001] The invention relates to a preparation method of a feed additive, in particular to a preparation method of a feed additive which uses Artemisia sativa as a raw material. Background technique [0002] At present, most of the dairy cows in my country are in the middle or low production level due to the poor quality of roughage, low level of scientific feeding management and other reasons, and the breeding efficiency is low. To solve this problem, we can produce high-value-added functional milk by adding feed additives in dairy cow rations, which can not only increase breeding benefits, but also conform to the current concept of healthy diet. The content of functional substances in milk is of great significance for improving milk quality and nutritional value of milk. According to FDA (2004), plant extracts are safe and non-toxic to human food and drugs, so plant extracts are currently widely used in animal production as a new type of feed additive. Con...
