Feed Acidifiers: A Revolutionary Force for Green Livestock Raising
Release time:
2025-04-30
Under the global trend of “reducing antibiotics and replacing them with alternatives,” Feed acidifiers Thanks to its characteristics of being residue-free, non-antibiotic-resistant, and safe and environmentally friendly, it has become one of the core alternatives to antibiotics in modern animal husbandry. As a green feed additive, acidifiers regulate the digestive tract environment of animals, enhance nutrient absorption efficiency, and inhibit the proliferation of pathogenic bacteria. They are now widely used in pig, poultry, aquaculture, and ruminant farming, injecting new momentum into improving production efficiency and food safety.
I. The Core Mechanism of Action of Acidifiers
Acidifiers optimize the digestive environment by lowering the pH of feed and the gastrointestinal tract. Their mechanisms of action include:
1. Activating Digestive Enzymes: Pepsin exhibits optimal activity at a pH of 2.0–3.5. Acidifiers can activate pepsinogen, thereby promoting protein breakdown and enhancing feed utilization.
2. Regulating the gut microbiota: Harmful bacteria (such as Escherichia coli and Salmonella) thrive in neutral environments, whereas beneficial bacteria (such as lactobacilli) prefer acidic environments. Acidifiers inhibit the proliferation of pathogenic bacteria, promote the colonization of beneficial bacteria, and reduce the incidence of diarrhea.
3. Promoting nutrient absorption: Acidifiers form readily absorbable complexes with minerals, thereby enhancing the bioavailability of elements such as calcium and phosphorus. Certain organic acids (such as fumaric acid and citric acid) directly participate in the tricarboxylic acid cycle, providing energy for the body.
4. Antioxidant and Immune Enhancement: Acidifiers such as citric acid can enhance the activity of antioxidant enzymes in animal serum, thereby reducing stress-induced damage. At the same time, by modulating intestinal barrier function, they promote the secretion of immunoglobulins.
II. Application Scenarios and Achievements Across Multiple Domains
1. Piglet Raising: Alleviate weaning stress and reduce the incidence of diarrhea.
Weaned piglets have insufficient gastric acid secretion, and feed with a relatively high pH can easily lead to digestive disorders and diarrhea. Adding a compound acidifier (such as potassium diformate or citric acid) can significantly reduce intestinal pH, inhibit the growth of Escherichia coli, increase daily weight gain, and lower the incidence of diarrhea.
2. Poultry Production: Improving Egg Quality and Enhancing Disease Resistance
Adding citric acid to chicken feed can improve feed palatability, reduce fatty liver, increase blood phosphorus levels and eggshell strength, and boost egg production. In addition, acidifiers help lower the risk of respiratory diseases by inhibiting pathogenic bacteria (such as Escherichia coli) in the drinking water system, thereby purifying the farming environment.
3. Aquaculture: Optimizing Digestion, Stress Resistance
Adding a composite of 0% citric acid and fumaric acid to fish feed can prolong the retention time of chyme in the intestine, thereby promoting protein digestion. At the same time, it helps alleviate stress responses caused by factors such as transportation and changes in water temperature, thus improving survival rates.
4. Ruminants: Replacing antibiotics to improve feed conversion rates
Compound acidifiers can reduce ruminal methane production, increase propionate concentration, and improve energy metabolism. When acidifiers are added to lamb diets, weight gain rates increase and feed conversion efficiency is optimized.
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.
