Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of livestock and poultry breeding, and particularly to a feed for improving the quality of chicken meat and a preparation method thereof. Background Art

[0002] With the development of modern large-scale breeding, the output of chicken meat has increased significantly, but the quality is uneven. The current common problem is that the chicken meat from large-scale breeding is only fishy and not fragrant, and there is an obvious gap in flavor and taste compared with the chicken meat from traditional free-range breeding. This is mainly because in the traditional free-range mode, chickens can freely forage on natural foods, have a wide range of activities, and a relatively long growth cycle. These factors combined give the chicken meat a unique flavor and better meat quality. However, in modern large-scale breeding, in order to pursue growth speed and economic benefits, a single feed formula is often used, the activity space of chickens is limited, and the growth cycle is shortened, resulting in insufficient accumulation of flavor substances in the chicken meat, lack of umami and fragrance, and the meat quality is also not satisfactory.

[0003] Therefore, how to improve the quality of chicken meat from large-scale breeding and restore the original fresh and fragrant flavor of chicken meat has become an urgent problem to be solved. Summary of the Invention

[0004] For this reason, the embodiments of the present invention provide a feed for improving the quality of chicken meat and a preparation method thereof.

[0005] In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:

[0006] According to the first aspect of the embodiments of the present invention, the present invention provides a feed for improving the quality of chicken meat, comprising the following raw materials in parts by weight: 40-60 parts of corn, 20-30 parts of soybean meal, 10-20 parts of wheat bran, 7.5-17.5 parts of aromatic agent, 4-8 parts of umami enhancer; the aromatic agent is selected from one or more of osmanthus, pine needles, geranium leaves, white cardamom, tsaoko, white pepper, and nutmeg; the umami enhancer is selected from one or more of angelica dahurica, galangal.

[0007] Further, the aromatic agent comprises 1-3 parts of osmanthus, 2-5 parts of pine needles, 1-2 parts of geranium leaves, 1-2 parts of white cardamom, 1-2 parts of tsaoko, 0.5-1.5 parts of white pepper, and 1-2 parts of nutmeg.

[0008] Further, the umami enhancer comprises 2-4 parts of angelica dahurica, 2-4 parts of galangal.

[0009] According to the second aspect of the embodiments of the present invention, the present invention provides a preparation method of the feed for improving the quality of chicken meat as described in any one of the above, the method comprising:

[0010] Weigh each raw material according to the ratio;

[0011] Crush each raw material into fine powder of 80 - 100 mesh respectively;

[0012] Premix corn, soybean meal and wheat bran, then add the fragrance agent and umami enhancer, and continue to stir and mix evenly to obtain the feed.

[0013] Furthermore, the conditions for premixing are: 200 - 300 revolutions per minute, 3 - 5 minutes, and the time for continuous stirring is 10 - 15 minutes.

[0014] According to the third aspect of the embodiments of the present invention, the present invention provides a breeding method for improving the quality of chicken meat, adopting a breeding method of combined greenhouse pen - raising and natural foraging, and feeding the feed as described in any one of the above during the growing period and fattening period of chickens.

[0015] The embodiments of the present invention have the following advantages:

[0016] 1. By adding fragrance agents such as osmanthus, pine needles, geranium leaves, white cardamom, tsaoko, white pepper, nutmeg, etc. in a specific proportion to the feed, the present invention effectively removes the fishy smell of chicken meat and adds a unique aroma; the addition of angelica dahurica and galangal (sand ginger) significantly enhances the umami of chicken meat, enabling the chicken meat produced by breeding to reach or even exceed the fresh fragrance level of traditional free - range chicken meat, meeting the needs of consumers for high - quality chicken meat flavor.

[0017] 2. After more than two years of experimental verification, by using the feed and breeding method of the present invention, the tenderness of the greenhouse - raised chicken at the time of slaughter is significantly improved, and the meat quality is more tender and fragrant compared with that of traditional free - range old hens. This not only improves the taste of chicken meat, but also broadens the choices of cooking methods for chicken meat, enhancing the market competitiveness of chicken meat products.

[0018] 3. The present invention adopts a breeding method of combining pen - raising and natural foraging. By using greenhouse pen - raising, it not only ensures that the growth environment of chickens is controllable, facilitating management and disease prevention and control, but also combines the natural foraging law. A natural foraging area is set in the greenhouse, allowing chickens to obtain natural food and supplement natural nutrients, simulating some conditions of traditional free - range, and promoting the improvement of chicken meat quality from multiple aspects.

[0019] 4. The raw materials of the feed formula of the present invention are widely sourced, the cost is relatively controllable, the breeding method is simple to operate, and it is easy to be popularized and applied in large - scale breeding. It can significantly improve the quality of chicken meat without significantly increasing the breeding cost, thereby increasing the breeding income, and has good economic benefits and practicability.

[0041] 1. Test chickens and grouping

[0042] Select 240 chicken seedlings of the same batch and in good health. Randomly divide the chicken seedlings into 6 groups, with 40 in each group. Among them, groups 1-5 are experimental groups and are fed with the feeds of Examples 1-5 respectively, and group 6 is the control group and is fed with a conventional commercial chicken feed.

[0043] 2. Feeding management

[0044] The experimental groups 1-5 adopt a breeding method of cage rearing in a shed combined with natural foraging. The experimental group 6 adopts a traditional free-range breeding method.

[0045] Brooding period (0-4 weeks old): The chicken seedlings in each group are raised in the same brooding environment and fed with the same form of conventional feed. Feed 6-8 times a day, and the feeding amount each time should be appropriate for the chicks to finish eating within 15-20 minutes.

[0046] Growing period (5-12 weeks old): Each group is fed according to its respective feed, 4-5 times a day, with free foraging. Regularly clean and disinfect the shed to keep the breeding environment hygienic.

[0047] Finishing period (13 weeks old - slaughter): Each group continues to be fed according to its respective feed. Feed 3-4 times a day, and adjust the feeding amount according to the feeding situation of the chickens, and it is appropriate for the chickens to finish eating within 20-30 minutes.

[0048] 3. Data collection

[0049] When the chickens were sold, 20 chickens were randomly selected from each group for slaughter. A panel of 10 professionally trained sensory evaluators was invited to conduct a sensory evaluation of the appearance, color, aroma, umami, and tenderness of the chicken. The evaluation criteria are shown in Table 1. Without knowing the sample grouping, the evaluators independently evaluated each index of each chicken, and finally calculated the average sensory evaluation score of the chicken in each group.

[0050] Table 1

[0051]

[0052] 4. Test Results

[0053] The results of the sensory evaluation of chicken quality are shown in Table 2 below.
