Description

Technical Field

[0001] The invention belongs to the technical field of feed additives, and mainly relates to a compound preparation for improving the egg production rate of laying hens and a preparation method thereof. Background Art

[0002] The egg production rate of laying hens directly affects the economic benefits of the farm. A high egg production rate means a large egg output and increased income for the farm; conversely, a low egg production rate will lead to reduced income and increased breeding costs. There are many reasons for the decline in the egg production rate of laying hens, among which disease, stress, and nutrition are the main factors. Improving the physique of laying hens, improving immunity and disease resistance, reducing stress, and supplementing nutrition can effectively increase the egg production rate of laying hens.

[0003] Methionine is required for many reactions in animals and is also called "life amino acid". Methionine is the only sulfur-containing amino acid among essential amino acids. It is almost all used for protein synthesis in animals, and a small part is metabolized and decomposed in the body and converted into important substances related to animal development.

[0004] Lysine, which cannot be synthesized by animals, is one of the essential amino acids that livestock and poultry are most likely to lack. It is a necessary component for synthesizing nuclear proteins and hemoglobin in brain nerves, germ cells, etc. Growing animals are very sensitive to lysine deficiency. The faster the growth rate and the higher the growth intensity, the more lysine is needed. Therefore, lysine can be called a "growth amino acid". When it is deficient, livestock and poultry will stagnate in growth, and there will be phenomena such as reduced subcutaneous fat, emaciation, and abnormal bone calcification.

[0005] Cod liver oil mainly contains vitamin A and vitamin D. In addition to supplying the nutrients needed for egg production, the vitamin A in it can maintain the integrity of the epithelial cells of the body's parenchymal organs, enhance the body's resistance, and promote the body's growth and development.

[0006] Probiotics are living or dead microorganisms and their metabolites that maintain the microecological balance of the digestive tract. When consumed by livestock and poultry, probiotics can increase the number of beneficial microorganisms in the intestines and inhibit the growth of pathogenic microorganisms, thereby changing the microecological structure in the intestines, enhancing the body's immune function and achieving the purpose of promoting animal growth.

[0007] Vitamin C can improve animals' immunity and disease resistance, enhance immune effects, fight various stresses, promote bone development, increase reproduction rate, and improve eggshell quality. It has a good effect on improving animals' health and production performance.

[0008] Atractylodes macrocephala, tonifies the spleen and replenishes qi, dries dampness and promotes diuresis, stabilizes the fetus, and stops sweating. It is mainly used to treat spleen deficiency diarrhea, edema, fetal movement disorder, and spontaneous sweating. It has the effects of promoting animal growth, increasing feed intake, reducing feed-to-meat ratio, and reducing mortality. It can stimulate the growth and development of animal immune organs, activate lymphocytes, increase immunoglobulin and antibody levels, and enhance cellular immunity and humoral immunity.

[0009] Chuanxiong promotes blood circulation and qi, dispels wind and relieves pain. It has the effect of resisting vitamin E deficiency and can inhibit a variety of bacilli, and has anti-histamine and choleretic effects.

[0010] Achyranthes bidentata nourishes the liver and kidneys, strengthens tendons and bones, removes blood stasis and dredges the meridians, and guides blood downward. Adding Achyranthes bidentata to feed can improve growth performance, enhance immunity and disease resistance.

[0011] Raw Rehmannia root nourishes yin and promotes the production of body fluids, clears away heat and cools blood. It is used for fever due to yin deficiency, epistaxis, hematuria, and sore throat. Raw Rehmannia root contains rich nutrients, such as rehmannia root, mannitol, calcium, selenium, iron, vitamin A and vitamin C, which significantly promote the health of animals. Adding raw Rehmannia root to feed can enhance the immunity of animals, promote digestion and absorption, protect the liver and detoxify, relieve disease symptoms, and supplement beneficial bacteria, thereby improving the overall health of animals.

[0012] Cyperus rotundus can relieve liver depression, regulate qi and relieve fullness, and promote blood circulation and relieve pain. It is used for qi and blood stagnation, chest and abdominal distension and pain, and abdominal pain after childbirth. Cyperus rotundus can affect ovarian function. Adding Cyperus rotundus to the diet can improve the reproductive function of laying hens and increase egg production rate.

[0013] Lycium barbarum nourishes the liver and kidneys, improves the essence and improves eyesight. It is used for liver and kidney yin deficiency, weak waist and limbs, and tears in the wind. Lycium barbarum contains polysaccharides, betaine, carotene, riboflavin, vitamin C, multiple amino acids and vitamins. It can improve the production performance of animals, make the animals' coats shiny and their muscles plump. It can regulate blood lipids and blood sugar, promote the regeneration of liver cells and significantly improve kidney lesions. It can remove free radicals in the body and inhibit free radical damage to the liver. It can regulate immune function and increase the number and activity of lymphocytes and macrophages.

[0014] Pine needles contain a variety of amino acids, trace elements and vitamins, which can effectively stimulate the ovulation function of laying hens, thereby increasing the egg production rate. They also contain phytoncide, which can promote the growth of livestock and poultry, prevent gastrointestinal diseases and various vitamin deficiencies.

[0015] The above drugs are scientifically and rationally matched according to the nutritional requirements of chickens during egg laying and the need for conditioning of body functions, with the aim of enhancing the body's immunity and reproductive performance, regulating the gastrointestinal tract, increasing feed intake, and promoting growth and development. At the same time, the process of making granules after fermentation of traditional Chinese medicine not only improves the bioavailability of the drug, but also makes it easy to use, with stable quality, and uses green raw materials with no residue and no drug resistance, which is safe and effective. Summary of the invention

[0057] (II) Test methods (1) Experimental design: 7,000 healthy laying hens with basically uniform body weight were selected from 15,000 laying hens in the same chicken house and divided into 7 groups, with 4 replicates in each group and 250 hens in each replicate. After grouping, the egg production rates of the 6 groups were analyzed by biostatistics, and there was no significant difference (P>0.05). The experimental period was 48 days.

[0060] (3) The test results are shown in Table 1.

[0061] Table 1 Production performance of laying hens As can be seen from Table 1, the average egg production rate of the experimental group was 91.32%, which was 2.5%, 3.1%, 4.2% and 5.0% higher than that of the control groups 1, 2, 3 and the blank control group respectively; the feed-to-egg ratio of the experimental group was 1.95 on average, which was 0.03, 0.07, 0.20 and 0.36 lower than that of the control groups 1, 2, 3 and the blank control group respectively; the average total egg weight of the experimental group was 2664, which was 4.7%, 5.1%, 8.5% and 11.4% higher than that of the control groups 1, 2, 3 and the blank control group respectively; the number of dead chickens in the experimental group was 6 on average, which was 4, 5, 12 and 18 fewer than that of the control groups 1, 2, 3 and the blank control group respectively.
