Meat duck feed additive as well as preparation method and application thereof

Abstract

The invention provides a meat duck feed additive. The additive is prepared from raw materials as follows: 5-15 parts of radix glycyrrhizae, 5-10 parts of herba menthae, 5-15 parts of cortex eucommiae,10-20 parts of flos lonicerae, 10-20 parts of herba taraxaci, 10-30 parts of fructus crataegi, 10-30 parts of red dates, 5-15 parts of pericarpium citri reticulatae, 10-25 parts of sagittaria sagittifolia, 10-20 parts of radix curcumae longae, 5-15 parts of rhizoma smilacis glabrae, 10-30 parts of caulis spatholobi, 5-20 parts of cortex eucommiae, 5-15 parts of herba lophatheri and 5-10 parts ofcortex cinnamomi. A preparation method of the meat duck feed additive comprises steps as follows: a, the raw medicinal materials are put in a pulverizer for pulverization and then are sieved; b, particles obtained after sieving are put in ethanol and subjected to heating reflux extraction twice; c, herb residues obtained after ethanol extraction are taken and subjected to heating reflux extractiontwice with water; d, two extracting solutions are combined, a mixed solution is subjected to ethanol recovery under reduced pressure and spray drying, dry extract is obtained and pulverized finally,and fine powder is obtained.

Description

technical field [0001] The invention relates to a meat duck feed, in particular to a meat duck feed additive and a preparation method thereof. Background technique [0002] Duck is a common poultry in our country. Under the background of modern large-scale production, more and more animals such as chickens and poultry are standardized on a large scale to meet the needs of the public; in order to improve production speed and economic benefits, feed for ducks Among them, additives such as antibiotics, hormones, chemical drugs, and synthetic pigments are used to promote the growth of ducks and improve the color of duck eggs. Currently, feed additives are widely used in feed production. A large amount of antibiotic additives that promote growth and improve immunity are added in violation of regulations. The meat ducks raised in this way contain a large amount of antibiotics or hormones, resulting in serious problems of drug residues in duck meat, especially by-products such as d...

[0002] Duck is a common poultry in our country.

Currently, feed additives are widely used in feed production. A large amount of antibiotic additives that promote growth and improve immunity are added in violation of regulations. The meat ducks raised in this way contain a large amount of antibiotics or hormones, resulting in serious problems of drug residues in duck meat, especially by-products such as duck liver. will cause harm to human health

[0003] Green, high-quality, and antibiotic-free feed additives are favorable guarantees for the production of high-quality poultry meat and poultry egg products. The development and utilization of natural plant resources and Chinese herbal medicines to replace antibiotics and chemical drugs has become a research hotspot in the field of feed additives; The rational development and utilization of natural plant resources, especially herbal medicines with the same source of medicine and food, based on the combination of traditional Chinese medicine theory and modern pharmacological effects, is an important way to improve poultry egg production rate and egg quality, and improve poultry meat quality. One of the ways; but unfortunately, there is a lack of pure natural feed additives for poultry that can be used in large-scale breeding and have significant effects
