detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Those who do not indicate the specific conditions in the examples are carried out according to the conventional conditions or the conditions suggested by the manufacturer. The reagents or instruments used were not indicated by the manufacturer, and they were all conventional products that could be purchased from the market.

The feed additive of the embodiment of the present invention and its preparation method are described in detail below.

The embodiment of the present invention provides a feed additive, which is mainly made of ginseng stems and leaves and traditional Chinese medicine bags with a weight ratio of 1:0.25-9. The traditional Chinese medicine bag is mainly made of the following raw materials in parts by weight: 10-20 parts of immune enhancer, 9-20 parts of carcass quality improver, 23-45 parts of food enhancer and 5-10 parts of antimicrobial agent.

Specifically, ginseng stems and leaves have pharmacological effects similar to those of ginseng roots, and the pharmacological effects of ginsenosides contained in ginseng stems and leaves are the same as those of ginseng root saponins, and the total number of saponins in ginseng stems and leaves is significantly higher than that in ginseng roots. At the same time, ginseng stems and leaves are abundant and the price is much lower than that of ginseng roots. Therefore, using ginseng stems and leaves as raw materials for feed additives can not only enhance the body's resistance, regulate body functions, promote substance metabolism, regulate central nervous system and endocrine functions, etc. , It also greatly saves economic costs and improves economic returns.

Specifically, a reasonable combination of immune enhancers, carcass quality improvers, feed enhancers, and antimicrobial agents, combined with ginseng stems and leaves, can improve the production performance, immune level, and carcass quality of broilers during the fattening period, thereby further improving the corresponding economic benefits.

Among them, the immune enhancer can enhance the immunity and disease resistance of broilers in the fattening period, and improve and promote the non-specific immune function of the body. The immune enhancer can be selected from one or more of astragalus, Ligustrum lucidum, licorice, Codonopsis pilosula and Angelica sinensis.

The main active ingredient of astragalus is astragalus polysaccharide, which has a wide range of biological functions such as anti-virus, anti-tumor, anti-oxidation, hypoglycemic, anti-stress, anti-radiation, anti-aging, and improving animal immunity. It has the advantages of no residue, no toxic and side effects, simple preparation process, low price, and safe use. It is a natural, green, and new feed additive. In the process of using and fattening broilers, on the one hand, astragalus polysaccharides can increase the activity of antioxidant enzymes in broilers during the fattening period, increase the deposition of lutein, thereby improving the color of egg yolk, enhancing protein metabolism of eggs, increasing protein concentration, and regulating egg production. The concentration of calcium ions in the egg makes the eggshell calcium source and thickness of the egg increase. On the other hand, astragalus and ginseng stems and leaves are both good medicines for invigorating qi. However, ginseng focuses on invigorating vitality, restoring yang and rescuing the adversity. It is often used in emergencies such as collapse, and the effect is better. Astragalus, on the other hand, is mainly used to tonify deficiency, and is often used in cases of prolonged body failure, weak speech, and weak pulse. Therefore, a reasonable combination of astragalus and ginseng stems and leaves can effectively improve and promote the body's non-specific immune function.

The polysaccharides, vitamins, volatile oils, glycosides, alkaloids, organic acids and other bioactive ingredients contained in Ligustrum lucidum can stimulate the growth of livestock and poultry, maintain the normal balance of the internal environment of animals, fundamentally protect and coordinate the overall health of livestock and poultry, Enhance the immune function of the body, regulate the beneficial microbial flora in the body, give full play to and improve the potential ability of the body itself to prevent diseases. Nutrients such as amino acids, mineral elements, and proteins in Ligustrum lucidum are beneficial supplements to the nutritional value of feed, providing nutrients for animal growth, promoting growth, and improving production performance. At the same time, Ligustrum lucidum can also adjust the flavor of chicken and improve the taste of chicken.

The dry roots and rhizomes of licorice leguminous plants Ural licorice, bulging licorice and glabra have excellent characteristics such as cold resistance, heat resistance, drought resistance, and salt-alkali resistance. On the one hand, licorice has estrogen-like effects, which can regulate the hormones in broilers during the fattening period, reduce the feed-to-meat ratio, and can significantly increase the apparent metabolic rate of crude protein in the diet. On the other hand, glycyrrhizic acid in licorice has the function of significantly enhancing the immunity of animals. Glycyrrhizic acid can significantly increase the production of antibodies. Intravenous injection of glycyrrhizic acid can significantly increase the antibody level and increase the activity of the reticuloendothelial system, so it can further improve non-specific immune function with assisting immune enhancers.

Codonopsis Codonopsis is a plant of Platycodonaceae, which has a sweet and flat taste, non-toxic, and has the effects of nourishing the middle, replenishing qi, promoting body fluid and quenching thirst. Indications for weakness of the spleen and stomach, deficiency of Qi in the middle, deficiency of Qi in the skin and lungs, and injury to body fluid due to febrile disease. Chickens in the laying period use qi and blood, and eggs are metabolized by qi and blood, especially broilers in the high-yield fattening period consume too much qi and blood during laying, which leads to a decline in the body's production capacity and disease resistance, affecting egg production performance or cause disease. Codonopsis pilosula is ideal for nourishing qi and nourishing blood, which can advance the peak egg production period of broilers during the fattening period and prolong the peak period. At the same time, it can also increase egg weight and improve feed utilization efficiency, which has good economic benefits.

As a feed additive, angelica not only has nutritional effects, but also can effectively improve the production performance, immune function and meat and egg quality of chickens. The combined use of angelica and codonopsis can not only ideally maintain the egg production rate and egg production of broiler chickens during the fattening period, but also The feed-to-egg ratio is reduced, thereby effectively improving the production performance of broilers during the fattening period. In the late stage of laying chickens, due to the decline of hematopoietic function and other physiological metabolism in the body, there will often be a decrease in egg production rate, soft eggshells, white eggshells and poor meat quality. Angelica has a good effect of nourishing blood and activating Qi, so it can improve muscle quality and egg quality.

Of course, in other embodiments of the present invention, the immune enhancer can also be replaced by other Chinese herbal medicines that can provide the same effects as Astragalus, Ligustrum lucidum, Acanthopanax, Angelica, and Codonopsis. For example, the immune enhancer can also be pokeweed , Aristolochia, melon pedicle, Andrographis paniculata, garlic, the present invention is not limited.
