Description

Technical Field

[0001] This invention relates to the field of poultry feed technology, specifically to a complete nutritional feed formula with a very simple composition designed for free-range chickens (native chickens). The formula contains only three basic materials: wheat bran, mealworms (dried mealworms), and corn, without the need to add any other ingredients such as soybean meal, fish meal, limestone powder, premix (vitamins, minerals, amino acids, etc.), oils, or other additives. Background Technology

[0002] Free-range chickens, due to their near-natural living environment and high activity levels, have tender and nutritious meat, making them highly popular with consumers. Feed is a key factor influencing the growth performance and meat quality of free-range chickens, and its formulation directly determines the success of the farming operation.

[0003] Existing free-range chicken feed typically contains multiple ingredients, and often includes artificial additives such as antibiotics and growth promoters to improve growth rate or disease resistance. However, multi-ingredient formulations not only increase production costs, but the complex combination of ingredients may also lead to nutritional imbalances; the use of artificial additives may leave residues in the chicken meat, affecting food safety and product quality, which contradicts consumers' demand for green and natural foods.

[0004] Therefore, developing a feed formula that is simple in composition, free of artificial additives, and can meet the nutritional needs of free-range chickens has become an urgent problem to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing free-range chicken feed, such as complex composition and artificial additives, and to provide a nutritious chicken feed formula composed of only three natural materials, so as to achieve the unity of nutritional balance and green farming.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] A nutritional chicken feed formula for free-range chickens, the formula consisting of only the following three materials in weight percentage: 50%-70% corn, 15%-30% dried yellow mealworms, and 15%-25% wheat bran, and the sum of the weight percentages of the three materials is 100%.

[0008] Preferably, the formula contains 55%-65% corn, 20%-25% dried mealworms, and 15%-20% wheat bran.

[0009] More preferably, the formula contains 60% corn, 20% dried mealworms, and 20% wheat bran.

[0010] Raw material requirements:

[0011] Corn: Select mature, dry, and mold-free yellow or white corn, and crush it to a suitable particle size (e.g., passing through a 1.5-3.0mm sieve).

[0012] Dried yellow mealworms: Select clean-raised yellow mealworm larvae or pre-pupae that have been dried at high temperature or freeze-dried, and crush them into a uniform powder (e.g., passing through a 0.5-1.0mm sieve).

[0013] Wheat bran: Select fresh, non-lumpy, and mold-free wheat processing by-products (wheat bran), and crush them to a suitable particle size (e.g., pass through a 1.5-3.0mm sieve).

[0014] A method for preparing nutritional feed for free-range chickens, characterized by comprising the following steps:

[0015] Step 1: Weigh out the corn, dried mealworms, and wheat bran according to the specified proportions;

[0016] Step 2: Grind the corn and wheat bran into powder;

[0017] Step 3: Put the three processed materials into the mixer and mix them thoroughly.

[0018] Step 4: After mixing thoroughly, the mixture can be packaged or used directly for feeding. No other ingredients need to be added.

[0019] In one embodiment, the coefficient of variation (CV) of the mixing uniformity is ≤10%.

[0020] application:

[0021] The feed formulation described in this invention is suitable for free-range broiler chickens, dual-purpose (egg and meat) chickens, or local breed chickens. It can be used as their main complete diet or as a supplement to their core concentrate feed. In free-range conditions, chickens can freely forage for natural foods such as grass, insects, and sand. The feed of this invention provides the necessary basic energy, protein, and fiber nutrition.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Minimalist and natural ingredients: Contains only three basic agricultural / aquaculture products, completely eliminating chemically synthesized additives (vitamins, minerals, amino acids, drugs, growth promoters, etc.), limestone powder, phosphates, salt, and other protein sources (soybean meal, fish meal), minimizing potential food safety risks and conforming to the concept of green and organic farming.

[0024] 2. Relatively Balanced Nutrition: Through a carefully designed ratio, corn provides ample energy and carbohydrates, mealworms provide high-quality animal protein, fat, and chitin (which contributes to gut health and immunity), and wheat bran provides essential fiber, B vitamins, and minerals (especially phosphorus). This combination can basically meet the main nutritional needs (energy, protein, essential amino acid profile, major minerals, and some vitamins) of free-range chickens in a free-range environment without relying on exogenous additives.

[0025] 3. Significantly reduced costs: The variety of raw materials is minimal, resulting in significantly reduced procurement, storage, and processing costs; there is no need to purchase expensive premixes and additives; mealworms can be produced in-house or raised on a large scale, making costs controllable.

[0026] 4. Improve chicken quality: Natural ingredients and moderate nutritional levels (non-growth-promoting) help chickens grow naturally, promote muscle fiber development and flavor substance deposition, and are expected to significantly improve the firmness, flavor, texture and juiciness of chicken.

[0027] 5. Improved farming efficiency: Reduced feed costs and improved chicken quality lead to higher selling prices. Combined with free-range farming, the overall economic benefits are significant.

[0028] 6. Easy to operate: Raw materials are readily available, the mixing process is simple, and it is easy to prepare the mixture on the farm. Attached Figure Description
