Description

Technical Field

[0001] This invention belongs to the field of animal nutrition technology, specifically relating to the application of a geographically sourced feed composition. Background Technology

[0002] Globally, pig feed is primarily based on corn-soybean meal. my country is a major producer and consumer of pork; in 2021, Hunan Province alone produced over 60 million pigs, ranking among the top three in the country. Because my country's corn and soybean production cannot meet the needs of the livestock industry, corn and soybeans have long been imported, with the majority originating from the United States. This has made corn and soybean meal two major obstacles to the rapid development of my country's livestock industry. Therefore, alleviating the current urgent demand for corn and soybean meal in the livestock industry, making full use of locally sourced feeds, and exploring feeding methods adapted to local pig farming characteristics are particularly important.

[0003] In addition, purines are important nitrogenous bases in the body, metabolized into uric acid. Excessive purine intake or purine metabolism disorders can lead to hyperuricemia, increasing the incidence of gout and harming health. Meat is highly nutritious and flavorful, widely popular among consumers, and constitutes a large proportion of people's daily diets. However, meat is also a high-purine food (76-398 mg / 100g). Excessive meat intake can significantly affect blood uric acid levels and increase the incidence of gout. Summary of the Invention

[0004] This invention aims to scientifically reduce the purine content in pork to meet consumers' demand for healthy, high-quality pork, and provides a locally sourced feed composition and its application.

[0005] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0006] The geographically sourced feed composition does not contain corn or soybean meal; the geographically sourced feed composition includes growing-stage feed and fattening-stage feed; the growing-stage feed consists of the following components by weight percentage: 35% rice bran, 25% broken rice, 25% corn citric acid residue, 10% sweet potato or pumpkin, 1% soybean oil, and 4% premix; the fattening-stage feed consists of the following components by weight percentage: 30% rice bran, 34% broken rice, 20% corn citric acid residue, 6% sweet potato or pumpkin, 1% soybean oil, 1% dried tangerine peel powder, 4% black tea powder, and 4% premix.

[0007] Preferably, the premix in the growing feed consists of the following components by weight percentage: 27.2% rice bran meal, 0.25% methionine, 1.25% threonine, 0.3% betaine, 2% choline chloride, 0.5% antioxidant, 8% sodium chloride, 0.625% baking soda, 0.625% potassium chloride, 30% limestone powder, 6.25% dicalcium phosphate, 1% antimicrobial peptide, 0.5% glucose oxidase, 0.625% livestock and poultry compound enzyme, 0.25% sweetener, 0.625% piglet multivitamin, 2.5% pig trace element complex, 16.25% lysine, and 1.25% mold inhibitor.

[0008] Preferably, the livestock and poultry complex enzyme contains phytase, xylanase, glucanase, and protease (in any proportion).

[0009] Preferably, the porcine trace element complex contains copper, iron, manganese, zinc, and selenium (in any proportion).

[0010] Preferably, the premix in the fattening feed consists of the following components by weight percentage: 43.25% rice bran meal, 0.125% methionine, 1% threonine, 0.25% betaine, 2% choline chloride, 0.5% antioxidant, 8.75% sodium chloride, 0.75% baking soda, 0.75% potassium chloride, 25% limestone powder, 5% dicalcium phosphate, 0.625% livestock and poultry compound enzyme, 0.25% sweetener, 0.625% piglet multivitamin, 2.5% pig trace element complex, 7.375% lysine, and 1.25% mold inhibitor.

[0011] Preferably, the livestock and poultry complex enzyme contains phytase, xylanase, glucanase, and protease (in any proportion).

[0012] Preferably, the porcine trace element complex contains copper, iron, manganese, zinc, and selenium (in any proportion).

[0013] The preparation method of the above-mentioned local feed composition is as follows: First, put local feed rice bran, broken rice, sweet potato, or rice bran, broken rice, and pumpkin into a steamer in proportion and steam for 40 minutes. Then, take it out and let it cool at room temperature. After that, dry it to make a local feed mixture for later use. Then, put the local feed mixture, other feed ingredients and premix in a mixer in proportion, stir evenly, and pack it into bags of 20kg-40kg and seal them.

[0014] The geographically derived feed composition of the present invention can be used to prepare feed that reduces the purine content of pork; it can be applied to regulate and reduce the purine content of pork.

[0015] The present invention will be further described below:

[0016] Geographically sourced feeds refer to the general term for local feed resources that can be used on a large scale after being processed into feed. They are characterized by unique nutritional value, low raw material costs, strong seasonality, and a certain geographical range. Unconventional feeds are material resources that are rarely used in current formulations, have certain nutritional value, and can be used by livestock and poultry. They are usually byproducts of food processing and functional substance extraction. Corn citric acid residue is a corn-free byproduct of corn fermentation for citric acid extraction. It has a high protein content, good palatability, and is safe and non-toxic, and can be used to replace soybean meal. The geographically sourced feed composition described in this invention does not contain corn or soybean meal. It is mainly composed of geographically sourced feeds (rice bran, broken rice, sweet potatoes, pumpkin) with high annual output and low price in Hunan, unconventional feeds (corn citric acid residue), black tea powder, and dried tangerine peel powder, etc. The feed raw materials are readily available and low in cost, which meets the needs of the national "Soybean Meal Reduction and Substitution Action" and the need to develop "low-protein, low-soybean meal diversified feed formulas".

[0017] This invention, through the scientific design of geographically sourced feed compositions, compares the effects of these compositions and commercial feeds on the growth performance and purine content of pork in large-bred pigs and crossbred pigs, determining suitable diets and feeding methods for these breeds. The findings provide a scientific basis and technical support for replacing corn and soybean meal with geographically sourced feeds and selecting appropriate local pig farming methods. This also provides technical support for improving resource utilization efficiency and pork product quality, reducing breeding costs, and has significant economic and social benefits. Furthermore, it helps meet the growing demand for high-quality meat. Detailed Implementation

[0018] Unless otherwise specified in this specific embodiment, all raw materials and reagents are commercially available.

[0032] The experiment was divided into three groups, using 50 crossbred pigs of similar age, body condition, health status, and weight (approximately 25 kg) in each group, with 25 pigs in each group. Five replicates (pens) were designed, with 5 pigs per pen. Group 1 used a localized feed composition; Group 2 used commercial feed (corn-soybean meal diet, purchased from a large feed manufacturer in Hunan). In the first phase of the experiment, the pigs were fed growing pig feed. Once the average weight of the pigs in each group reached approximately 65 kg, they were switched to finishing feed until slaughter.

[0033] Although geographically sourced feed compositions lead to a higher feed conversion ratio, the raw materials for these compositions are cheaper, resulting in lower per-kg weight gain costs for pigs. Furthermore, the levels of xanthine, hypoxanthine, and total purines in pork are significantly lower than in commercial feed groups.

[0038] This study used a corn-soybean meal-based commercial feed and a probiotic product with metabolic regulating functions as controls to test the feeding effect of the patented localized feed formula. The experiment was divided into three groups, using 66 large-bowled pigs of similar age, body condition, health status, and weight (approximately 25 kg), with 22 pigs in each group and 5 replicates (pens), with 4-5 pigs per pen. Group 1: Localized feed composition; Group 2: Commercial feed (corn-soybean meal-based diet, purchased from a large feed manufacturer in Hunan); Group 3: Commercial feed + probiotic agent (containing Lactobacillus, Bacillus, etc., purchased from a biotechnology company in Hunan). In the first stage of the experiment, the pigs were fed growing pig feed. Once the average weight of the pigs in each group reached approximately 55 kg, they were switched to fattening feed until slaughter.

[0039] While geographically sourced feed compositions may lead to a higher feed conversion ratio, the raw materials for these compositions are inexpensive, resulting in lower costs per kg of weight gain for pigs. Adding probiotics to commercial feed significantly improves feed nutrient conversion efficiency, leading to faster weight gain and thus lower costs per kg of weight gain. Analysis of purine and metabolite content in pork shows that geographically sourced feeds significantly reduce the levels of xanthine, hypoxanthine, guanine, and total purines in large-sized piglets, with better results than probiotics.
