Description

Technical Field

[0001] The present application relates to the technical field of feed additives, and in particular to a feed additive, laying hen feed, and a preparation method thereof. Background Art

[0002] At present, laying hens are popular among farmers. The quality of eggs produced by laying hens mainly depends on the nutritional structure of the feed and the feeding habits of the chickens.

[0003] With the popularization of artificial feeding, various feed additives have emerged one after another. The nutrients they contain make laying hens have poor digestion and absorption of feed, resulting in lower egg production rates, lighter weight of single eggs, and lower feed conversion rates, thereby reducing breeding efficiency.

[0004] Currently, there are various ingredients in feed additives for improving the production performance of laying hens. After feeding laying hens, the odor concentration in the poultry house is high, which leads to damage to the health of livestock and poultry; and the breeding environment is poor, which is not conducive to environmental hygiene. Summary of the Invention

[0005] In order to solve the above technical problems, the present application provides a feed additive, laying hen feed and a preparation method thereof.

[0006] In a first aspect, the present application provides a laying hen feed additive, specifically comprising the following components in parts by weight: 50-60 parts of Chinese herbal medicine extract, 2-4 parts of polypeptide, 1-3 parts of antioxidant and antibacterial agent, and 0.6-1.2 parts of trace elements; The Chinese herbal medicine extract is prepared from Platycodon grandiflorum, Solanum nigrum and Angelica sinensis in a weight ratio of 4-6:2-3:0.5-1; The polypeptide is obtained by mixing rapeseed pollen peptide and lily oligopeptide in a weight ratio of 5-13:0.5-3; The antioxidant and antibacterial agent is selected from one or more of sodium D-isoascorbate, phytic acid, sorbic acid, sodium sorbate, and potassium sorbate.

[0007] This application takes "promoting egg production - reducing nitrogen emissions - inhibiting bacteria and odor" as the core goals, designs a compound feed additive formula, and compounds Chinese herbal compound extracts (Plantago-Solanum nigrum - Angelica sinensis) + polypeptides + antioxidants and antibacterial agents + organic trace elements in specific proportions to break through the limitations of a single ingredient.

[0008] The Chinese herbal extract is prepared using platycodon, solanum nigrum and angelica sinensis in a specific weight ratio. The platycodon extract contains saponins, polysaccharides, flavonoids and other ingredients; the solanum nigrum extract contains alkaloids, saponins, flavonoids, polysaccharides and other ingredients; the angelica sinensis extract contains phthalides, polysaccharides, coumarins and other ingredients. The combination of the three can promote the secretion of reproductive hormones of laying hens by regulating their endocrine system, thereby increasing egg production and egg weight; at the same time, these ingredients can promote digestion and absorption of laying hens and enhance their physical fitness, thereby indirectly increasing egg production and egg weight; in addition, the extract has anti-inflammatory and antioxidant effects, which help maintain the health of laying hens and further ensure their high yield.

[0009] Among peptides, the active ingredients in rapeseed pollen peptides and lily oligopeptides (such as antimicrobial peptides and phenolic substances) can regulate the balance of intestinal microorganisms, inhibit the growth of urease-producing and sulfate-reducing bacteria, thereby reducing urea decomposition (NH3 source) and sulfur-containing organic matter degradation (H2S source); these small molecule peptides can enhance the absorption efficiency of amino acids and minerals in the intestines of laying hens, reduce the excretion of unused nitrogen and sulfur, and reduce the accumulation of ammonia and sulfide in feces from the source; and these two peptide substances can synergistically regulate intestinal mucus secretion or fecal pH, and slow down the volatilization of nitrogen / sulfur compounds.

[0010] In addition, the mixture of rapeseed pollen peptides and lily oligopeptides can provide essential amino acids to promote egg white / eggshell synthesis; peptides can form "peptide-metal complexes" with organic trace elements to improve the bioavailability of elements, maintain intestinal enzyme activity, and promote the conversion of energy and protein in feed.

[0011] Antioxidants and antibacterial agents can be used to inhibit harmful intestinal bacteria, such as urease-producing bacteria and sulfate-reducing bacteria; reduce free radical damage to the intestine; and regulate intestinal pH and acidic environment to inhibit ammonia production.

[0064] Performance testing The laying hen feed provided in the examples and comparative examples was used as the test object, and the egg production rate and egg quality of the laying hens after eating the laying hen feed were tested.

[0065] Test method: 46-week-old Hailan brown laying hens were selected and observed for one week. The egg production was roughly similar, the hens were healthy and disease-free, and the body shape was basically the same. The pre-test period was 10 days.

[0066] Layers were grouped into equal groups of 100 and housed according to standard procedures: artificial light supplemented in the morning and evening, combined with natural light during the day, for a combined duration of 16 hours. The hens were fed with natural ventilation, water, and the laying hen feed provided in the Examples and Comparative Examples. A control group of laying hens was fed a basal diet. The hens were fed once daily at 8:00 AM and 4:00 PM. The henhouses were cleaned and disinfected daily according to standard procedures. The experimental period lasted 21 days. The temperature was 25°C, and the relative humidity was 50%. The hens' health was observed daily, and the following parameters were tested.

[0067] The specific measurement indicators are: (1) Production performance of laying hens: Collect eggs at 11:00 a.m. and 18:00 p.m. every day, collect the total number of eggs, calculate the average daily egg production rate and average egg weight; and calculate the feed-to-egg ratio, that is, the amount of feed required to produce 1 kg of eggs.

[0068] (2) Performance of improving the environment in the chicken house: The detection points are the four diagonal corners and the center point of the poultry house, 30 cm from the ground (the height of the chicken's breathing zone); the concentrations of ammonia and hydrogen sulfide are detected at 21:00 on the first, tenth and twenty-first days of the experiment.

[0069] Test results: as shown in Table 2.

[0070] Table 2 Application performance test results of laying hen feed in Examples and Comparative Examples From the test results in the above table, it can be seen that the feed additive prepared by using the technical solution provided by this application for feeding laying hens can effectively improve the egg production rate and average egg weight of laying hens, reduce the feed-to-egg ratio, improve the feed conversion rate, and greatly improve the breeding production efficiency; at the same time, it can effectively reduce the generation and release of ammonia and hydrogen sulfide in the poultry house, which is beneficial to promoting the health of livestock and poultry, and improving the breeding environment and environmental hygiene.

[0071] By comparing the test results of Examples 1-5 and Comparative Examples 1-2, it can be seen that the amount of each raw material component has a significant impact on the performance of the feed. The present application uses 50-60 parts of Chinese herbal medicine extracts, 2-4 parts of polypeptides, 1-3 parts of antioxidants and antibacterial agents, and 0.6-1.2 parts of trace elements as feed additives, effectively improving the application performance of the feed additive.

[0072] By comparing the test results of Examples 3, 6-10, and Comparative Examples 3-5, it can be seen that in Comparative Example 3, the herbal extract of Solanum nigrum was substituted for Angelica sinensis with an equal amount; in Comparative Example 4, the herbal extract of Artemisia capillaris was substituted for Angelica sinensis with an equal amount; and in Comparative Example 5, the herbal extract was prepared from Platycodon grandiflorum, Solanum nigrum, and Angelica sinensis in a weight ratio of 8:1:2, and the application performance of the feed additive was poor. In contrast, the herbal extract prepared in the present application from Platycodon grandiflorum, Solanum nigrum, and Angelica sinensis in a weight ratio of 4-6:2-3:0.5-1 effectively improved the application performance of the feed additive.

[0073] By comparing the test results of Examples 3, 11-12 with Comparative Examples 6-8, it can be seen that the polypeptide in Comparative Example 6 is obtained by mixing kombucha peptides and lily oligopeptides in a weight ratio of 9:1.5, the polypeptide in Comparative Example 7 is obtained by mixing rapeseed pollen peptides and lotus seed oligopeptides in a weight ratio of 9:1.5, and the polypeptide in Comparative Example 8 is obtained by mixing rapeseed pollen peptides and lily oligopeptides in a weight ratio of 1.5:9. The prepared feed additives are used to feed laying hens, and the degree of improvement of ammonia and hydrogen sulfide in the poultry house is very limited. In contrast, the present application selects a polypeptide obtained by mixing rapeseed pollen peptides and lily oligopeptides in a weight ratio of 5-13:0.5-3, which can effectively improve the breeding environment and environmental hygiene in the poultry house. Furthermore, the present application selects to control the weight ratio of rapeseed pollen peptides and lily oligopeptides to 7-11:1-2.

[0074] By comparing the test results of Examples 3 and 13-14, it can be seen that the antioxidant and antibacterial agent in Example 13, which is composed of a mixture of sodium D-erythorbate and potassium sorbate in a weight ratio of 1:1, and the antioxidant and antibacterial agent in Example 14, which is composed of a mixture of sodium D-erythorbate and phytic acid in a weight ratio of 1:10, have a lower degree of improvement in ammonia and hydrogen sulfide in the poultry house. In contrast, the antioxidant and antibacterial agent composed of a mixture of sodium D-erythorbate and phytic acid in a weight ratio of 1:1 can further reduce the generation and release of ammonia and hydrogen sulfide in the poultry house, thereby improving the breeding environment and environmental hygiene.

[0075] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made based on the present invention. Therefore, such modifications and improvements, which do not depart from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
