Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding, and particularly to a feed and a breeding method capable of improving the immunity of poultry. Background Art

[0002] With the rapid development of the livestock and poultry breeding industry, poultry products occupy an increasingly important proportion in global meat consumption. In order to improve the production performance and economic benefits of poultry, improving their body immunity, reducing the incidence of diseases, and reducing the dependence on antibiotics have become one of the key issues urgently needed to be solved in the breeding industry. As a green and sustainable immune regulation method, nutritional intervention has received great attention in recent years. Especially, the introduction of functional nutrients and probiotics into the feed formula has a significant effect on improving the health status of poultry.

[0003] At present, some research and products have tried to regulate the balance of intestinal flora and enhance immune function by adding active substances such as probiotics, plant extracts, and polysaccharide compounds to the feed. For example, single components such as lactic acid bacteria probiotics, oligosaccharide prebiotics, tea polyphenols, or ganoderma lucidum polysaccharides are used for functional supplementation, or formula combinations are designed based on experience for feeding. However, most formulas are still mainly statically designed in fixed proportions, lacking dynamic regulation strategies, and lacking support and mechanisms in the evaluation of poultry immune status and precise nutritional intervention.

[0004] At the same time, the existing feeding methods lack precise identification and differential supply of the immune needs of poultry at different growth stages, which easily leads to nutritional waste or increased immune burden, and fail to systematically integrate and analyze feeding behaviors, poultry immune indicators, and poultry house environmental parameters, making it difficult to form targeted nutritional intervention strategies.

[0005] How to solve the above technical problems is the subject faced by the present invention. Summary of the Invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a feed and a breeding method capable of improving the immunity of poultry, which can achieve precise nutritional intervention, significantly improve the immune regulation effect, and reduce the impact of environmental stress.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the present invention provides a feed capable of improving the immunity of poultry, including a basic feed component, a probiotic precise regulator, and an immune nutrition enhancer, wherein the basic feed component is 85-90 parts, the probiotic precise regulator is 4-6 parts, and the immune nutrition enhancer is 4-6 parts; The basic feed component includes 60-65 parts of corn, 20-25 parts of soybean meal, 2-5 parts of wheat bran, 1-3 parts of fish meal, and 1-2 parts of premix; The microecological regulator includes 2.5 - 3.5 parts of probiotics and 1.0 - 2.5 parts of prebiotics. The probiotics in the microecological regulator are selected from one or more of the genera Lactobacillus, Bifidobacterium, and Bacillus. The prebiotics in the microecological regulator are one or more of fructooligosaccharides and galactooligosaccharides.

[0008] The immune nutrition enhancer includes 1.5 - 2.5 parts of natural polyphenols, 1.5 - 2.5 parts of polysaccharides, and 1.0 - 1.5 parts of amino acids. The natural polyphenols in the immune nutrition enhancer are selected from one or more of tea polyphenols, grape seed extract, rosemary extract, or pomegranate polyphenols. The polysaccharide components in the immune nutrition enhancer include one or more of ganoderma lucidum polysaccharide, lentinan, or astragalus polysaccharide. The amino acids in the immune nutrition enhancer are one or more of arginine, glutamine, and cysteine.

[0009] A feeding method for a feed that can improve the immunity of poultry includes the following steps: S1. According to the breed, age, and weight of the poultry, determine its growth stage. For example, for fast-growing broilers (such as white - feather chickens): it is divided into the chick stage (1 - 21 days) and the growth stage (22 - 42 days). For local breeds (such as yellow - feather chickens): it is divided into the young poultry stage (1 - 28 days) and the fattening stage (29 - 56 days). In the chick stage: when <500g, increase the immune enhancer; in the fattening stage: when >2kg, reduce the basic feed and increase the microecological agent. S2. Record the feeding behavior data of the poultry. For example, when the daily feed intake drops by 15%, immediately add glutamine + prebiotics; when the feeding duration is >2h for 3 consecutive days, reduce wheat bran and increase fructooligosaccharides; when the feeding frequency fluctuates abnormally, increase the dosage of Bifidobacterium. S3. Monitor the changes in immune - related indicators of the poultry and poultry house environmental parameters. The immune - related indicators include serum immunoglobulin levels, intestinal flora diversity, and inflammatory factor expression levels, which are regularly sampled and analyzed through a data acquisition system. The poultry house environmental parameters include ammonia concentration, carbon dioxide concentration, suspended particulate matter concentration, water - borne microbial content, and bacterial population in the bedding. For example, when IgG <5mg / ml, increase the immune enhancer; when IgA <2mg / ml, adjust the proportion of Lactobacillus in the probiotics to 70%; when Escherichia coli is detected, completely replace the current probiotics with Bacillus; when the proportion of Bifidobacterium <10%, add galactooligosaccharides. For example, when ammonia >20ppm in the poultry house environmental parameters, reduce the basic feed and increase the probiotics; when CO2 >3000ppm, add tea polyphenols for anti - stress; when the coliform bacteria in the water exceed the standard, completely replace the polysaccharides in the immune enhancer with astragalus polysaccharide. S4. Dynamically adjust the addition ratios of the basal feed, microecological regulator, and immune nutrition enhancer in the feed according to the records and monitoring results of S1 - S3, and implement the feed - environment linkage regulation measures. The adjustment of the dynamic formula is based on the establishment of an immune response evaluation model, and the batching is carried out through the feedback results of the model. The model comprehensively inputs the poultry immune - related indicators, feeding behavior data, and poultry house environment parameters, and dynamically predicts the immune status and conducts risk grading through machine learning algorithms. The feedback results are used to adjust the feed nutrition ratio and additive level.

[0010] The beneficial effects of the present invention are as follows: By scientifically formulating the basal feed, microecological regulator, and immune nutrition enhancer, and based on the growth stage characteristics such as poultry breed, age, and weight, combined with the real - time monitored feeding behavior data, immune indicators, and poultry house environment parameters, the present invention dynamically adjusts the proportion of each component, achieving a breakthrough from static feeding to precise nutritional intervention, effectively solving the problems of fixed formula and lagging adjustment in the prior art. While maintaining the balance of intestinal flora and enhancing immune function, it significantly reduces the impact of environmental stress on poultry health, making the immune regulation more targeted and stable.
