Summer use of acidifiers in animal husbandry—safeguarding animal health and production efficiency.
Release time:
2025-07-30
In the height of summer, the hot and humid environment not only challenges human comfort but also poses a severe test for the livestock industry. Heat stress runs rampant, feed intake declines, intestinal diseases become increasingly common, and production performance plummets—these “summer syndromes” have become an ever-present shadow haunting livestock farmers. In this battle against high temperatures, the scientific application of feed acidifiers is emerging as a crucial tool for enhancing animals’ summer health and ensuring the profitability of livestock farming.

Feed acidifiers is becoming a key tool for enhancing animals’ summer health and ensuring the profitability of livestock farming.
1. Resist heat stress and maintain homeostasis of the body.
In high-temperature environments, animals tend to breathe faster and drink more water, which can easily lead to respiratory alkalosis and disrupt the body's acid-base balance. High-quality compound acidifiers—such as those containing citric acid and fumaric acid—can produce alkaline salts through metabolism, effectively buffering blood pH and correcting acid-base imbalances. Meanwhile, specific organic acids—such as butyric acid—can rapidly provide energy, reducing the metabolic burden associated with high temperatures and helping animals cope more calmly with heat stress challenges.
II. Strong “appetite stimulation” to enhance feeding motivation.
Heat stress significantly suppresses animal appetite. The distinctive sour and aromatic scent of acidifiers—such as lactic acid and malic acid—can effectively stimulate taste buds and enhance feed palatability. Studies have shown that the appropriate addition of acidifiers can increase feed intake in broilers and pigs during summer, providing a solid nutritional foundation for maintaining growth and egg production.
3. Strengthen the intestinal health defense and inhibit pathogenic bacteria.
Summer is the high season for intestinal diseases (such as E. coli and Salmonella infections):
Lowering gastrointestinal pH: Acidifiers reduce the pH in the stomach, activating pepsinogen and enhancing protein digestibility. At the same time, they create an acidic intestinal environment that significantly inhibits the proliferation of harmful bacteria.
Antimicrobial effect: Small-molecule organic acids such as formic acid and propionic acid can penetrate bacterial cell membranes, release hydrogen ions that disrupt the internal pH balance, and directly kill or inhibit pathogenic bacteria—achieving an efficacy comparable to that of certain antibiotics.
Promote the proliferation of beneficial bacteria: Butyric acid and other compounds serve as preferred energy sources for gut probiotics (such as Lactobacillus), helping beneficial microbial communities establish dominance, competitively inhibit pathogenic microorganisms, and stabilize the gut microbiota balance.
4. Optimize digestion and absorption, and unlock the potential of feed.
High temperatures often lead to a decrease in the activity of digestive enzymes:
Activating digestive enzymes: Acidifying the gastric environment is a prerequisite for pepsin to function efficiently, and the addition of organic acids significantly enhances protein digestibility.
Chelated mineral elements: Citric acid, lactic acid, and other chelating agents can form readily absorbable complexes with minerals such as calcium, phosphorus, and zinc, thereby enhancing the bioavailability of these mineral elements.
Slowing gastric emptying: Moderate acidity prolongs the residence time of chyme in the stomach, enhancing the efficiency of nutrient digestion and absorption. As a result of these combined effects, feed conversion ratio can be improved and increased.
5. Collaborate on mold prevention and freshness preservation to ensure feed safety.
High temperature and high humidity accelerate feed spoilage by promoting mold growth. Propionic acid, sorbic acid, and other similar compounds are themselves highly effective mold inhibitors. When added to feed as acidifying agents, they can inhibit mold growth, reduce the risk of toxin production, extend the safe storage period of feed, and minimize nutrient losses during summer.
Scientific Selection and Application Recommendations:
1. Precise Combination: A single acid has limited effectiveness. Choose a scientifically formulated composite acidifier (e.g., formic acid + propionic acid for antibacterial action, citric acid + butyric acid for growth promotion) to harness synergistic effects and enhance performance.
2. Focus on encapsulation technology: Acidifiers that employ controlled-release encapsulation technologies (such as microcapsules or lipid protection) can target the hindgut, enhancing utilization efficiency and reducing losses in the stomach.
3. Reasonable Dosage and Stages: Adjust the addition amount according to the animal species, age, health condition, and degree of high temperature. Young animals and those in periods of stress generally have higher requirements. Strictly follow the product instructions and expert guidance.
4. Compatibility: Pay attention to incompatibilities between acidifiers and trace elements, vitamins, and other additives (such as zinc oxide) to avoid reducing efficacy.
Latest experiment
Broiler Glucose Oxidase Experiment
One-day-old Ross 308 broiler chickens were selected, with a total of 4 chicken houses, each housing 11,000 birds. The birds were randomly divided into a control group and a treatment group, with 2 chicken houses assigned to each group. The control group was fed a commercial diet supplemented with Changle (allicin and oregano phenol) at 100 mL/ton, while the treatment group was fed a commercial diet supplemented with glucose oxidase at 100 U/L. During the trial period, birds had free access to feed and water. The trial lasted for 42 days. The experimental diet consisted of corn, soybean meal, wheat, cottonseed meal, DDGS, peanut meal, duck fat, and premixes, among other ingredients; nutritional parameters are shown in Table 1.
Lactic Acid Bacteria Experiment
Effect of Lactic Acid Bacteria on Broiler Diarrhea: A Raising Experiment Experimental Site: Jiyang Zheng* Animal Husbandry Farm Experiment Period: August 31, 2015 – September 4, 2015 Experimental Subjects: 30-day-old broilers Experimental Design: Control Group: Normal feeding + normal drinking water Experimental Group: Normal feeding + normal drinking water + lactic acid bacteria (liquid)
Piglet Fruit Milk Flavor Experiment
Twenty 28-day-old weaned piglets of the Duroc × Landrace × Large White crossbreed, with similar body weights and in good health, were selected for the trial. They were randomly divided into two treatment groups: a control group and a test group. The control group was fed a basal diet, while the test group was fed a basal diet supplemented with 600 g/t of fruit-milk flavoring. Each group consisted of five replicates, with two piglets per replicate. During the trial period, the pigs had free access to feed and water, and the trial lasted for 28 days.
In this trial, 120 healthy, growing pigs of similar body condition, weighing 80 ± 10 kg, were randomly divided into a control group, an antibiotic group, and an essential oil group. The specific feeding design is shown in Table 1. Each group consisted of 4 replicates, with 10 pigs per replicate. The trial duration was 29 days. The experimental diet was formulated according to the nutritional requirements outlined in NRC (2012). During the trial, pigs had free access to feed and water, and were subjected to routine husbandry management and vaccination protocols. Body weights at the beginning and end of the trial, as well as feed intake, were recorded. At the end of the trial, fresh fecal samples were collected from each pig, placed into sterile 10 ml centrifuge tubes, and stored at -80℃.
Tian Yikang replaces chlortetracycline in the ROSS-308 trial.
This experiment employed a single-factor experimental design. A total of 6,000 Ross-308 broiler chickens, aged 1 day and with roughly similar body weights and good health conditions, were randomly selected and divided into three treatment groups, with five replicates per group, each replicate consisting of 400 chickens. The control group was fed a basal diet based on corn and soybean meal. The experimental group 1, the antibiotic group, had 50 g/t of a 15% chlortetracycline premix added to the basal diet. The experimental group 2, the Tianyikang addition group, had 1,500 g/t of Tianyikang added to the basal diet. The entire experiment lasted for 42 days.
Since 1998, focused on animal feed intake and health.
