Embodiment Construction

[0007] An example is described in detail below: the Artemisia annua of Compositae after cleaning 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 bottle, and extracted three times by heating, condensing and reflux with 55% ethanol , adding 400ml of ethanol each time, extracting for 2 hours at a temperature of 95°C, combining 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 according to the feed-to-milk ratio of 1:2.5, its daily concentrate feed intake is 8kg, and the daily addition of Artemisia annua ethanol extract per cow is 96g.

Abstract

The invention discloses a preparation method of Artemisia annaua feed additive. The preparation method is characterized by comprising the following steps: drying Artemisia annaua plants in the shade; then crushing the plants into coarse powder; adopting reflux extraction method and ethanol to extract active ingredients; and carrying out microwave drying to obtain powder. The preparation method is based on the principle of traditional Chinese medicine, modern biological technology is adopted and microwave drying is carried out on the extract, thus obtaining the Artemisia annaua feed additive. Artemisia annaua is annual herb feverfew and is distributed all over the country, thus being available; and the Artemisia annaua extract is taken as plant extract to finally produce CLA (conjugated linoleic acid), which is feasible.

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 using Artemisia annua 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. Conjugate...
