Description

Technical Field

[0001] The present invention belongs to the field of young rabbit feed, and particularly relates to a green feed composition for reducing the mortality rate of young rabbits and a preparation method thereof. Background Art

[0002] Young rabbits mainly refer to the period from birth to weaning. Usually, this stage is 0 - 4 weeks old. During this period, the various organs and systems of young rabbits are not yet fully developed, and their adaptability to the external environment is weak. They need to rely on breast milk to obtain nutrition and immunity to ensure their normal growth and development. Among them, breast milk is the main nutritional source for young rabbits during lactation. After a period of breast milk, young rabbit feed can be supplemented.

[0003] Currently, the main components of young rabbit feed usually include high-quality alfalfa meal, soybean meal, wheat bran, corn, fish meal, mineral and vitamin premixes, etc. For example, a young rabbit feed and its preparation method disclosed in CN107853462A include 20 - 30 parts of corn, 25 - 30 parts of wheat bran, 20 - 25 parts of soybean meal, 10 - 15 parts of purslane, 10 - 15 parts of carrot, 10 - 15 parts of sweet potato leaves, 10 - 12 parts of lentil grass powder, 10 - 12 parts of mulberry tree stems and leaves, 5 - 10 parts of marigold residue, 3 - 5 parts of coix seed outer coat, 0.6 - 0.9 parts of salt, 0.6 - 0.8 parts of forsythia, 1 - 2 parts of alfalfa, 0.3 - 0.9 parts of glucose, 0.6 - 1.0 parts of threonine, and 0.5 - 0.8 parts of lysine.

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of description, the words "upper", "lower", "left" and "right" as used hereinafter only indicate the same direction as the upper, lower, left and right directions of the accompanying drawings themselves, and do not limit the structure.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0030] Examples, such as Figure 1 、 Figure 2 and Figure 3 As shown in

[0031] A green feed composition for reducing the mortality rate of young rabbits provided by the present invention includes the following raw materials in parts by weight: 60-80 parts of alfalfa meal, 30-50 parts of soybean meal, 20-50 parts of wheat bran, 15-30 parts of corn, 5-10 parts of fish meal, 10-15 parts of egg white centrifugate, 1-5 parts of female rabbit saliva extract, and 1-3 parts of premix.

[0032] In particular, the present invention also adds egg white centrifugate and female rabbit saliva extract to the feed formula. The egg white centrifugate contains various nutrients, such as ovalbumin, ovotransferrin, lysozyme, vitamins such as vitamin A, vitamin D, vitamin B2, vitamin B12, etc.; minerals such as sodium, potassium, calcium, magnesium, iron, zinc, etc.; and there are also some immunoglobulins, peptides, etc. Immunoglobulins can help the body resist the invasion of foreign pathogens, and peptides have various physiological regulatory functions. Regarding the female rabbit saliva extract, the saliva of female rabbits contains various components that have a positive impact on young rabbits. For example, the saliva of rabbits contains digestive enzymes such as amylase. Amylase can break down starch in food into simple sugars such as maltose, which helps the initial digestion of food by young rabbits; the saliva of female rabbits contains immunoglobulins such as IgA. These immunoglobulins can enhance the immunity of young rabbits and help young rabbits resist the invasion of external pathogens. In the period after birth, the own immune system of young rabbits has not yet fully developed. The immunoglobulins obtained from the saliva of female rabbits can provide passive immune protection for them, reduce the risk of disease, and improve the survival rate of young rabbits; furthermore, by selecting different female rabbits, the saliva of female rabbits may contain some growth factors, such as epidermal growth factor (EGF), etc. These growth factors can promote the cell proliferation and differentiation of tissues and organs such as the oral cavity and gastrointestinal tract of young rabbits, contribute to the growth and development of various organs of young rabbits, and enable them to better adapt to the external environment. Therefore, a variety of raw materials in the formula can supplement reasonable protein, vitamins and minerals for young rabbits, and by adding female rabbit saliva extract, effective digestive enzymes, immunoglobulins and growth factors can be provided for the fed young rabbits, which is beneficial to reducing the mortality rate of young rabbits.

[0033] In a green feed composition for reducing the mortality rate of young rabbits provided by the present invention, the egg white centrifugate is from common egg sources, such as at least one of chicken egg white, duck egg white and quail egg white. The present invention preferably uses the egg white of Chinese white quail eggs as the egg white centrifugate. Chinese white quails start laying eggs at 45 days of age, with an average annual egg production rate of 80%-85%, an annual egg production of 265-300 eggs, an egg weight of more than 11 grams, and better laying performance than Korean quails and Japanese quails of the same period and are easy to raise. Furthermore, the amino acid composition of quail egg white is relatively close to the needs of young rabbits, with high biological utilization rate, and can provide the amino acids required for the growth, development, tissue repair and renewal of young rabbits, which helps to promote the growth of muscles, hair, etc. of young rabbits; quail egg white contains some special bioactive components, such as epidermal growth factor EGF, etc. EGF has the functions of promoting cell proliferation, differentiation and repair, and has a positive promoting effect on the growth and development and tissue repair of young animals. Although chicken egg white also contains some bioactive substances, the content of EGF in quail egg white is relatively high, and it may have more obvious advantages in promoting the growth of young animals such as young rabbits.

[0034] In order to reduce the pathogens in the mother rabbit saliva extract, the mother rabbit saliva extract provided by the present invention is the mother rabbit saliva that has been physically disinfected, and the concentration of the mother rabbit saliva extract is 8-15%, which can not only ensure the rationality of nutrition but also facilitate preservation.

[0035] A preparation method of a green feed composition for reducing the mortality rate of young rabbits includes steps: S1, raw material treatment and preparation; S2, batching; S3, mixing; S4, granulation; S5, cooling; S6, grading; S7, packaging. In particular, in step S3 of the present invention, the mixing order of the raw materials is controlled to be alfalfa meal, mother rabbit saliva extract, corn, egg white centrifugate, soybean meal, wheat bran, fish meal, and premix in sequence. First, the mother rabbit saliva extract can be better and more fully mixed in the alfalfa meal. Then, adding corn and egg white centrifugate can make the raw materials that have been added form an intermediate feed with a certain kneading effect. And after orderly adding other raw materials later and stirring for a period of time, a uniformly dispersed feed system is formed. On the one hand, it can ensure that the nutrition does not flow away, and on the other hand, it can also ensure the product quality and granulation efficiency of subsequent granulation. The feed produced by the whole set of processes has good nutritional components and palatability, and has good standardization, and is applicable to the large-scale feeding of young rabbits.

[0036] In order to ensure the utilization rate and nutrition of the raw materials, step S1 of the present invention specifically includes the following contents:

[0037] Cleaning and impurity removal: The raw materials of alfalfa meal, soybean meal, wheat bran, and corn are respectively screened and magnetically separated to remove stone particles, soil, and metal impurities in the raw materials. The screening process can screen out raw materials with larger particles as well as grass roots, branches, etc. And after removing the metal impurities, these reserved raw materials are beneficial to ensuring the safety and palatability of the feed for young rabbits;

[0038] Preparation of egg white centrifugate: Put a certain number of eggs into a tray with an egg slot, place the tray with eggs on the extraction working end of the extraction device, and the extraction device uses the needle tube negative pressure extraction method to suck the egg white. The extraction device puts the sucked egg white into a centrifugal device for separation and purification, and the purified egg white is reserved; Using the mechanical extraction method of egg white centrifugate can improve production efficiency and production scale;

[0039] Preparation of mother rabbit saliva extract: Extract the saliva of the mother rabbit, send the extracted saliva into the saliva collection tank, and disinfect the saliva collection tank and the saliva it contains by ultraviolet disinfection. The disinfected mother rabbit saliva is stored at low temperature for standby; Ultraviolet disinfection can reduce the pathogens in the mother rabbit saliva, and low-temperature storage can ensure the hygiene of the mother rabbit saliva extract before mixing;

[0040] Preparation of premix: Mix the required trace elements and stir well for standby.

[0041] Furthermore, in the process of preparing the egg white centrifugate, the extraction end of the extraction device is provided with two syringes. The needles of the two syringes are inserted into different depths of the egg at different angles for extracting the egg yolk and egg white. The extracted egg white also needs to be purified to reduce the doping ratio of egg yolk and eggshell debris in this raw material. In particular, the present invention preferably uses quail eggs as the egg source for the egg white centrifugate. The extraction method using syringes can reduce the use of fixtures for clamping and crushing eggs, reduce the fixture cost, and also reduce the difficulty of centrifugal separation, which is beneficial to improving the preparation efficiency of the egg white centrifugate.

[0042] In order to improve the hygiene of the female rabbit saliva extract, in the extraction process of the present invention, the female rabbit saliva is not concentrated first, but spread out in the saliva collection tank to make the original female rabbit saliva have a certain spreading area, which is beneficial to the sufficiency of ultraviolet disinfection. And in the process of preparing the female rabbit saliva extract, it is concentrated again before low-temperature storage, and the female rabbit saliva with a concentration of 5-10% is concentrated to 8-15%, thus completing the preparation and storage of the female rabbit saliva extract.

[0043] The method for extracting the saliva of female rabbits in the present invention is to select healthy and docile female rabbits, put a hollow plastic mouthpiece 1 on the female rabbits. The plastic mouthpiece 1 is provided with mesh holes 13 and its two ends are closed ends. Place fresh grass and carrots in the rabbit cage under light-shielding conditions. The grass and carrots are separated by a mesh cover to prevent being eaten and losing the inducing effect. Replace the plastic mouthpiece every 10-20 minutes, and squeeze out the saliva of the female rabbit from the plastic mouthpiece 12. Among them, the plastic mouthpiece 1 includes an elastic headband 11. The headband 11 can be put on the head of the female rabbit and is adapted to the head shape of the female rabbit. And its two sides and bottom can gently massage the cheeks and mandibular parts of the female rabbit while the female rabbit makes breathing and mouth-opening movements, stimulating its salivary glands to secrete saliva; the grass and carrots are not used as food but as inducing substances for inducing the female rabbit to secrete saliva. The induced saliva can enter the mouthpiece 12 through the mesh holes 13. Some absorbent accessories such as sponges can be stuffed into the mouthpiece 12. The saliva adsorbed by the absorbent accessories can be squeezed into the corresponding collection container after the plastic mouthpiece is taken off the head of the female rabbit. In this way, by regularly taking and placing the plastic mouthpiece, the purpose of effectively collecting the saliva of the female rabbit can be achieved.

[0044] In order to provide feed suitable for young rabbits to eat, in the present invention, the granulation particle size in step S4 is 40 mesh to 80 mesh. Such a particle size is more suitable for the digestion characteristics and feeding ability of young rabbits. If the mesh number is too coarse, the feed particles are too large, and it is difficult for young rabbits to chew and digest, which may lead to problems such as indigestion and gastrointestinal diseases; if the mesh number is too fine, the feed is too delicate, which will affect the air permeability and palatability of the feed. Young rabbits may not like to eat it. At the same time, it may also increase the risk of young rabbits inhaling dust during feeding, causing irritation to the respiratory tract.

[0045] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
