Laying duck feed additive and preparation method thereof

Abstract

The invention provides a laying duck feed additive. The laying duck feed additive is prepared from 5-15 parts of liquorice, 5-10 parts of mint, 10-20 parts of honeysuckle flowers, 10-20 parts of dandelions, 10-30 parts of hawthorns, 5-15 parts of dried orange peels, 10-30 parts of pine needles, 10-20 parts of rhizoma curcumae longae, 5-15 parts of glabrous greenbrier rhizome, 10-30 parts of caulisspatholobi, 5-20 parts of eucommia ulmoides, 5-12 parts of medicated leaven, 6-12 parts of fennel, 15-30 parts of astragalus membranaceus, 6-12 parts of codonopsis pilosula, 5-10 parts of angelica sinensis and 10-20 parts of portulaca oleracea. A preparation method comprises the following steps that 1, raw medicine materials are put into a crusher to be crushed and then sieved; 2, remaining particulate matter after sieving is put into ethanol for heating reflux extraction twice; 3, medicine residues after ethanol extraction are taken, and water is added for heating reflux extraction twice; 4,two kinds of extracted liquid are combined, decompression is conducted to recycle the ethanol, mist spraying and drying are conducted to obtain dry paste, and finally crushing is conducted to obtainfine powder.

Description

technical field [0001] The invention relates to a duck feed, in particular to a feed additive for laying ducks. Background technique [0002] With the development of modern large-scale production, the breeding of livestock and poultry is becoming more and more intensive. The commercial production time of egg ducks in my country is relatively short, the degree of intensification is poor, and the production differences are large. The production process is often affected by many adverse factors. The egg production performance of ducks cannot be fully exerted, and the egg production peak is unknown, the egg production time is short or the egg production rate drops sharply. Antibiotics have been used as feed additives in feed for decades, and have played a positive role in promoting the development of animal husbandry, especially in the prevention and control of livestock and poultry diseases and the promotion of growth. The number of poultry and the output of livestock products ...

Antibiotics have been used as feed additives in feed for decades, and have played a positive role in promoting the development of animal husbandry, especially in the prevention and control of livestock and poultry diseases and the promotion of growth. The number of poultry and the output of livestock products have been greatly improved. Along with a large number of these chemically synthesized feed additives and chemicals, antibiotics, growth-stimulating hormones and preservatives are commonly used in feed, and they have played a role in the development of animal husbandry. It has a certain promotion effect, but it also brings relatively large negative effects, especially the extensive use of antibiotics, and the resulting drug resistance and drug residues have brought great harm to human health.
