Description

Technical Field

[0001] This invention relates to the field of ruminant nutrition and feed processing technology, specifically to a highly stable buffer-type acid poisoning resistant beef cattle feed and its preparation method. Background Technology

[0002] Currently, China's beef cattle industry is developing rapidly in a large-scale and intensive manner. In order to quickly increase the daily weight gain of beef cattle and shorten the cycle, farms generally adopt a feeding pattern of high corn, high concentrate, and low roughage. Under this feeding pattern, starch in the rumen ferments rapidly, producing a large amount of lactic acid and volatile fatty acids, which exceeds the rumen's own buffering and metabolic capacity, resulting in a persistently low rumen pH and widespread subacute rumen acidosis.

[0003] Existing technical solutions have significant technical shortcomings: 1. Traditional single sodium bicarbonate buffer: It can only achieve instantaneous neutralization of acidity, and the buffering time is less than 4 hours. It cannot solve the problem of lactic acid accumulation at night, and the pH fluctuates repeatedly. It only treats the symptoms and not the root cause. 2. Commercially available acidified feeds: Most of them use a single organic acid to adjust palatability, but they do not have the function of lactic acid decomposition, cannot improve the rumen flora structure, and have an extremely high acidosis recurrence rate; 3. Existing antibiotic-free health feeds: The vast majority rely on traditional Chinese medicine and plant extract systems, which are costly, have unstable active ingredients, large batch-to-batch variations, and have a large number of homogeneous patents, lacking novelty; 4. Simple probiotic feed: Lacking a buffer system, the survival rate of probiotics is low in acidic environments, making effective colonization impossible and resulting in negligible regulatory effects.

[0004] Especially in beef cattle farming areas in northern my country, the closed pens, insufficient exercise, and inconsistent quality of roughage during winter place greater metabolic pressure on the rumen of beef cattle. This leads to persistent problems such as persistent acidosis, decreased feed intake, high feed conversion ratio, and lameness, which plague large-scale farms year-round. Therefore, developing a specialized feed that provides long-lasting buffering, breaks down lactic acid, repairs the rumen mucosa, and stabilizes the gut microbiota has extremely high industrial necessity and technological innovation value. Summary of the Invention

[0005] Purpose To address the shortcomings of existing technologies in the prevention and control of acidosis in beef cattle from high-concentrate feed—namely, limited buffering capacity, lack of lactic acid degradation capabilities, severe homogenization of plant extract formulations, and unstable efficacy—this invention provides a highly stable buffered acid-poisoning-resistant beef cattle feed and its preparation method. It completely abandons the plant extract system, constructing a four-dimensional synergistic system of organic acid salt slow-release buffering, probiotic lactic acid degradation, prebiotic colonization, and mineral ion mucosal repair. This system achieves long-term stability of rumen pH, prevents acidosis at its source, and improves beef cattle growth performance. It also boasts advantages such as novel formulation, controllable cost, and strong industrial adaptability.

[0006] Technical solution To achieve the above objectives, the present invention adopts the following technical solution: A highly stable buffering type acid poisoning resistant beef cattle feed includes a basic diet, wherein the feed contains a compound functional additive, which is composed of the following raw materials by weight: 6-12 parts of compound organic buffer salt, 2-4 parts of compound probiotics, 1.5-3 parts of prebiotic regulator, 1-2.5 parts of mineral mucosal repair agent, and 78.5-89.5 parts of carrier; The composite organic buffer salt is composed of sodium butyrate, magnesium malate, and tripotassium citrate in a mass ratio of 2:1.2:1. The compound probiotics are composed of Candida utilis and Bacillus subtilis in a live bacteria ratio of 3:1. The prebiotic regulator is a mixture of galactooligosaccharide and yeast β-glucan in a mass ratio of 1:1. The mineral mucosal repair agent is prepared by compounding chelated zinc and light magnesium oxide in a mass ratio of 2:1.

[0007] Furthermore, the total live bacteria count of the compound probiotics is ≥20 billion CFU / g.

[0008] Furthermore, the basic diet comprises, by weight percentage: 25%–56% corn, 3%–15% soybean meal, 5%–9% wheat bran, 10%–28% corn germ meal, and 2% beef cattle premix, with the compound functional additives accounting for 0.05%–1% of the total feed weight.

[0009] The present invention also provides a standardized preparation method for the feed, which maximizes the preservation of live bacteria activity and ensures uniform dispersion of mineral salts through low-temperature pretreatment and step-by-step compounding process, thereby avoiding functional failure. Beneficial effects

[0010] Compared with the prior art, this invention has substantial features and significant progress, and its core innovative advantages are as follows: 1. Completely new formula system This invention contains absolutely no plant extracts, traditional Chinese medicine, plant flavonoids, or plant essential oils. Unlike domestic and foreign beef cattle acid poisoning resistant feeds, it adopts a mineral organic acid salt + microbial complex system. The formula combination is a brand-new and unique ratio adapted to high-concentration beef cattle feed, with no overlap with existing publicly available technologies.

[0011] 2. A four-dimensional collaborative mechanism to overcome the shortcomings of single technologies. Traditional techniques only involve adjusting acidity or supplementing bacteria; this invention constructs a closed-loop control system. Organic buffer salts: long-lasting and sustained release, stabilizing rumen pH day and night, preventing lactic acid buildup at night; Compound probiotics: specifically break down lactic acid accumulated in the rumen, reducing acidity from the source; Prebiotics: Target the cultivation of beneficial bacteria, inhibit the proliferation of acid-producing harmful bacteria, and reshape the rumen microbiota; Chelated mineral ions: Repair rumen epithelial mucosa damaged by acidosis and resolve repeated stress damage.

[0012] The four-component formula works synergistically to produce unexpected technical effects far exceeding the sum of individual raw materials.

[0013] 3. Process optimization to address pain points in industry applications. By using ultra-fine grinding and low-temperature stepwise compounding processes, the problems of easy separation of mineral salts, high-temperature inactivation of probiotics, and uneven mixing are solved. The batch stability is far superior to that of conventional feed, and it has strong industrial mass production potential.

[0014] 4. Highly practical and with high industrial value. All raw materials are compliant with national standards for feed, making procurement convenient and cost-effective compared to plant extract formulations. Feeding operations are simple and do not require changes to the original feeding methods of the ranch. Trial verification has shown that it can maintain the rumen pH of beef cattle at a stable level of 6.2-6.8, reduce the incidence of acidosis by 20%-30%, improve feed conversion rate by 7%-12%, significantly reduce mortality, and significantly improve the economic benefits of large-scale farming. Detailed Implementation Example

[0015] The mass fraction of the compound functional additive is as follows: 9 parts compound organic buffer salt, 3 parts compound probiotics, 2 parts prebiotic regulator, 1.8 parts mineral mucosal repair agent, and 84.2 parts carrier.

Example

[0016] The mass fraction of the compound functional additive is as follows: 6 parts of compound organic buffer salt, 2 parts of compound probiotics, 1.5 parts of prebiotic regulator, 1 part of mineral mucosal repair agent, and 89.5 parts of carrier; the remaining parameters are the same as in Example 1. Example

[0017] The mass fractions of the compound functional additive are as follows: 12 parts of compound organic buffer salt, 4 parts of compound probiotics, 3 parts of prebiotic regulator, 2.5 parts of mineral mucosal repair agent, and 78.5 parts of carrier; the remaining parameters are the same as in Example 1.

[0018] Scale settings Comparative Example 1: Only add regular sodium bicarbonate (common commercial solution) Comparative Example 2: Only compound probiotics were added, without a buffering and repair system. Comparative Example 3: Health-promoting feed made from conventional plant extracts Feeding trial results 150 healthy beef cattle weighing 450±20kg were randomly divided into 6 groups for a 60-day high-concentrate feeding trial. The results showed that the rumen pH stability, feed intake, daily weight gain, and feed conversion ratio of beef cattle in Examples 1-3 of this invention were significantly better than those in the control groups. There were no acidosis complications such as diarrhea or lameness, and the effects were stable and excellent.
