Prevent Broiler Necrotic Enteritis with Probiotic Formula for Broilers

Necrotic enteritis (NE) caused by Clostridium perfringens is one of the most detrimental enteric diseases in broilers. In Indonesian commercial farms, NE outbreaks often trigger performance decline, increased FCR, and mortality spikes. However, probiotic-based approaches are proving effective as an antibiotic-free prevention strategy. Biosolution's Probiotic Formula for Broilers, combining Lactobacillus acidophilus, Bacillus subtilis, and Bacillus coagulans, has been tested in several commercial farms and shows promising results in suppressing Clostridium populations, improving gut health, and boosting productivity.

Why Necrotic Enteritis Is a Serious Problem in Broiler Farms

Necrotic enteritis is a necrotic disease of the small intestine triggered by Clostridium perfringens type A and C. This pathogen produces toxins that damage the intestinal mucosa, causing inflammation, diarrhea, and sudden death. Predisposing factors such as coccidiosis, high-protein feed, or environmental stress exacerbate the risk. In Indonesia, NE incidence is reported to reach 10–40% in flocks without proper preventive management. The economic impact is significant: reduced body weight, increased FCR, high treatment costs, and mortality losses. Broiler integrators are particularly vulnerable to these losses due to large-scale production. Therefore, effective and sustainable prevention strategies are a priority.

Role of Probiotic Formula for Broilers in Suppressing Clostridium

Biosolution's Probiotic Formula for Broilers is specifically designed to create an intestinal environment hostile to Clostridium while supporting broiler growth. Three superior strains work synergistically:

Lactobacillus acidophilus: Gut pH Reducer

Lactobacillus acidophilus produces lactic acid that lowers gut pH, inhibiting the growth of Clostridium and other pathogenic bacteria. This acidic environment also triggers digestive enzyme production and enhances nutrient absorption.

Bacillus subtilis: Enzyme Producer and Biocontrol Agent

Bacillus subtilis produces protease, amylase, and lipase enzymes that improve feed digestibility. Additionally, this strain produces antimicrobial compounds such as subtilin that directly suppress Clostridium perfringens.

Bacillus coagulans: Heat-Resistant Spores for Pelleted Feed

Bacillus coagulans forms spores resistant to high temperatures during pelleting, remaining viable upon reaching the intestine. These spores then germinate and compete with Clostridium for attachment sites and nutrients.

Competitive exclusion is key: probiotics adhere to the intestinal epithelium, block pathogen adhesion, and consume nutrients needed by Clostridium. As a result, Clostridium populations drop drastically, reducing NE risk.

Performance Results in Indonesian Commercial Farms

Trials of the Probiotic Formula for Broilers were conducted in three commercial farms in West Java and East Java with a total of 30,000 Cobb 500 broilers. Treatment was given from day-old chick (DOC) to harvest (35 days). Dosage: 1 ml/L drinking water daily during the starter phase (1–14 days) and 3 times weekly during the grower-finisher phase (15–35 days). Parameters monitored included FCR, ADG, mortality, and NE lesion score.

8–12% FCR Improvement

Average FCR in the probiotic group was 1.48–1.52, compared to 1.62–1.68 in the control. This means each kilogram of feed produced 8–12% higher body weight. This feed efficiency stems from improved digestion and nutrient absorption due to Bacillus enzymes and reduced pathogen load.

5–10% ADG Increase

Average daily gain (ADG) in the probiotic group reached 58–62 grams/day, while the control was 52–56 grams/day. Faster growth indicates optimal gut health and that feed energy is not wasted fighting infection.

Low Mortality (<3%)

Cumulative mortality in the probiotic group was only 2.1–2.8%, compared to 4.5–6.2% in the control. Specific NE-related deaths dropped sharply: 0.3% in probiotic vs 1.8% in control. NE lesion scores (0–4) averaged 0.5 (mild) in probiotic vs 1.8 (moderate) in control.

No Antibiotic Residues

All meat samples from the probiotic group tested negative for antibiotic residues, meeting the AGP-free standards increasingly required by slaughterhouses and consumers.

Scientific Mechanisms Behind the Probiotic Formula's Effectiveness

The effectiveness of the Probiotic Formula for Broilers is supported by three main mechanisms:

1. Competitive exclusion: Probiotics compete with Clostridium for nutrients and adhesion sites on the intestinal mucosa. Lactobacillus and Bacillus adhere faster and form a protective biofilm.
2. Lactic acid and antimicrobial production: Lactobacillus lowers gut pH, while Bacillus produces bacteriocins that directly kill Clostridium.
3. Immunomodulation: Probiotics stimulate secretory IgA production in the intestinal mucosa, strengthening local immunity. Immune cells such as macrophages and lymphocytes are also activated, leading to faster pathogen response.

Research from FAO and IRRI confirms that multistrain probiotics are more effective than single strains due to synergistic effects. The combination of Lactobacillus and Bacillus in this product provides comprehensive protection.

Practical Application for Integrators

The Probiotic Formula for Broilers is easy to apply via drinking water or feed. Recommended dosage: 1 ml/L drinking water or 2 ml/kg feed. During the starter phase (1–14 days), administer daily in the morning after feeding. During the grower-finisher phase (15–35 days), just 3 times weekly. The product is compatible with nipple drinker systems and does not settle, preventing line blockages.

For integrators using pelleted feed, Bacillus coagulans in heat-resistant spore form ensures viability is maintained. No feed formula adjustments are needed. Optimal results are achieved when applied from DOC, as probiotic colonization of the gut begins early.

Conclusion

Necrotic enteritis caused by Clostridium perfringens can be effectively prevented with Biosolution's Probiotic Formula for Broilers. Data from Indonesian commercial farms show 8–12% FCR improvement, 5–10% ADG increase, low mortality <3%, and no antibiotic residues. Competitive exclusion, lactic acid production, and immunomodulation are key to success. For integrators transitioning to AGP-free systems without sacrificing performance, this product is the right solution.

FAQ

What is necrotic enteritis in broilers?

Necrotic enteritis is a necrotic intestinal disease caused by Clostridium perfringens. Symptoms include diarrhea, lethargy, decreased appetite, and sudden death. The disease is triggered by factors such as coccidiosis, high-protein feed, or stress. The best prevention is maintaining gut health through probiotics and good management.

How does the Probiotic Formula for Broilers prevent necrotic enteritis?

This formula contains Lactobacillus acidophilus, Bacillus subtilis, and Bacillus coagulans that work synergistically: lowering gut pH, producing antimicrobials, competing with Clostridium, and stimulating local immunity. Thus, Clostridium populations are suppressed and NE risk is reduced.

Is this product safe to use without antibiotics?

Yes, this product is designed to support AGP-free systems. All strains are classified as GRAS (Generally Recognized as Safe) and leave no residues in meat. Commercial farm trials show performance equal to or better than antibiotic growth promoters.

What is the recommended dosage for broilers?

Recommended dosage is 1 ml/L drinking water or 2 ml/kg feed. Administer daily during the starter phase (1–14 days) and 3 times weekly during the grower-finisher phase (15–35 days). Apply in the morning after feeding for optimal results.
