Integrated Poultry House Biosecurity with Probiotics: Performance Evidence of Formula Probiotik Ayam Pedaging in Indonesian Commercial Farms

Poultry house biosecurity is a fundamental pillar of modern livestock management. However, many farmers still rely solely on chemical disinfection and physical barriers, unaware that gut microbial balance is a critical internal defense line. An integrated biosecurity approach now incorporates probiotics as biological agents that strengthen local immunity and naturally suppress pathogens. This article presents performance data from Indonesian commercial farms applying Formula Probiotik Ayam Pedaging from Biosolution, and discusses the scientific mechanisms behind its effectiveness.

Why Poultry House Biosecurity Needs to Be Strengthened with Probiotics?

Conventional biosecurity focuses on preventing pathogen entry from outside. However, pathogens such as Escherichia coli, Salmonella, and Clostridium are often already present in the barn environment and can proliferate if gut conditions are suboptimal. Probiotics, especially lactic acid bacteria and Bacillus sp., work on the principle of competitive exclusion—they compete with pathogens for nutrients and adhesion sites on the gut wall.

In Indonesia, disease pressure and temperature fluctuations make broilers susceptible to digestive disorders. The use of antibiotics as growth promoters (AGP) has been banned by the Ministry of Agriculture since 2018, making probiotics a strategic solution. Biosolution's Formula Probiotik Ayam Pedaging contains three superior strains: Lactobacillus acidophilus, Bacillus subtilis, and Bacillus coagulans. All three have synergistic roles in lowering gut pH, producing digestive enzymes, and modulating mucosal immune responses through IgA stimulation.

Data from commercial farms in West Java show that probiotic application from day one (D1) can suppress mortality rates to below 3% over a 35-day period, with an average FCR of 1.45–1.50, 8–12% better than controls without probiotics. This proves that internal biosecurity through probiotics is as important as external biosecurity.

Mechanism of Action of Formula Probiotik Ayam Pedaging in Suppressing Pathogens

### Competitive Exclusion and Lactic Acid Production

Lactobacillus acidophilus is the main lactic acid bacterium in this formula. This strain adheres to gut receptors and produces lactic acid, lowering the gut lumen pH to around 4.5–5.5. This acidic environment inhibits the growth of gram-negative bacteria such as Salmonella and E. coli. Additionally, L. acidophilus produces bacteriocins that are bactericidal against certain pathogens.

### Digestive Enzymes from Bacillus subtilis

Bacillus subtilis is known for producing protease, amylase, and lipase enzymes that improve feed digestibility. With better digestion, undigested feed residues decrease, thereby reducing substrate for pathogens in the lower gut. Enzymes also help break down anti-nutritional components, such as non-starch polysaccharides, which often cause high viscosity and trigger Clostridium growth.

### Heat-Resistant Spores of Bacillus coagulans

Bacillus coagulans has the advantage of spores that are resistant to feed pelleting temperatures (70–80°C). This means the probiotic remains stable when mixed into commercial feed. Once in the gut, spores germinate into vegetative cells and begin producing lactic acid (L+) and antimicrobial compounds. Its ability to survive the acidic stomach environment and bile salts makes it highly effective for broilers.

These three strains work synergistically: Lactobacillus and Bacillus coagulans lower pH, while Bacillus subtilis improves digestion. The end result is a reduction in pathogen populations, increased nutrient absorption, and strengthened mucosal immunity.

Performance Data in Indonesian Commercial Farms: FCR, ADG, and Mortality

The application of Formula Probiotik Ayam Pedaging has been tested in several commercial farms with scales of 10,000–50,000 birds per cycle. Here is a summary of achieved performance:

• FCR improvement of 8–12%: Average FCR in probiotic-fed birds reached 1.45–1.50 compared to controls at 1.60–1.65. This means significant feed savings per kilogram of live weight.
• ADG increase of 5–10%: Average daily gain increased from 45 g/day to 48–50 g/day during the grower phase.
• Mortality <3%: Mortality over 35 days of rearing dropped drastically, especially due to colibacillosis and necrotic enteritis.
• Zero antibiotic residues: With probiotics, therapeutic antibiotic use decreased by up to 70%, and meat is residue-free.

At one farm in Lampung, probiotic use from D1 to harvest (35 days) resulted in an average harvest weight of 2.1 kg with an FCR of 1.47. Meanwhile, a control farm with similar management but without probiotics recorded an FCR of 1.63 and mortality of 5.2%. These data confirm that probiotics are not merely supplements, but an integral component of poultry house biosecurity.

Proper Application Method for Formula Probiotik Ayam Pedaging

For optimal results, probiotic application must be consistent and at the correct dosage. Here are guidelines from Biosolution:

• Method: Via drinking water or feed. For drinking water, mix 1 ml of probiotic per liter of water. For feed, use 2 ml per kg of feed.
• Frequency: Daily during the starter period (week 1), then 3 times per week during the grower–finisher period.
• Timing: Administer in the morning after feeding, so that probiotics are not exposed to high temperatures during feed mixing.

It is important to ensure drinking water is free from excess chlorine, as chlorine can kill probiotic bacteria. If using a nipple system, ensure the dose is mixed homogeneously. For feed, probiotics should be mixed gradually (premix) for even distribution.

Probiotic application must also be accompanied by good external biosecurity management, such as barn disinfection, vector control, and all-in all-out. Probiotics are not a replacement, but a complement that strengthens internal defenses.

Comparison with Other Probiotics: Advantages of the 3-Strain Formula

On the market, many poultry probiotics contain only one or two strains. Biosolution's Formula Probiotik Ayam Pedaging excels due to its combination of three complementary strains:

• Lactobacillus acidophilus: Specifically adheres to the small intestine and produces lactic acid.
• Bacillus subtilis: Produces enzymes and antimicrobial compounds such as subtilin.
• Bacillus coagulans: Stable in pelleted feed and produces L+ lactic acid, which is more effective at suppressing pathogens.

Furthermore, this product has been tested under various Indonesian climatic conditions, including high temperatures and high humidity that often stress chickens. Data from farms in North Sumatra show that probiotic performance remains consistent even when barn temperatures reach 33°C.

Conclusion

Integrated poultry house biosecurity does not rely solely on disinfection and isolation, but also on strengthening internal immunity through probiotics. Biosolution's Formula Probiotik Ayam Pedaging has been scientifically and empirically proven to suppress pathogens, improve FCR by 8–12%, increase ADG by 5–10%, and reduce mortality below 3% in Indonesian commercial farms.

FAQ

What is integrated poultry house biosecurity?

Integrated poultry house biosecurity is a holistic approach that combines physical measures (disinfection, barriers), managerial measures (all-in all-out), and biological measures (probiotics, vaccination) to prevent the entry and spread of pathogens. Probiotics play a role in strengthening the digestive tract's defenses, thereby reducing infection risk.

How do probiotics work to improve FCR?

Probiotics such as Bacillus subtilis produce enzymes that break down hard-to-digest feed components, allowing more nutrients to be absorbed. Additionally, lowering gut pH inhibits pathogens that compete for nutrients, making feed energy more efficiently converted into meat.

Are probiotics safe to use without antibiotics?

Yes, probiotics are actually designed to reduce reliance on antibiotics. By naturally suppressing pathogens, the need for therapeutic antibiotics decreases drastically. Biosolution products are residue-free and safe for human consumption.

What is the correct dosage for broilers?

The recommended dosage is 1 ml per liter of drinking water or 2 ml per kg of feed. During the starter period, it is given daily, while during grower-finisher, 3 times per week. Ensure drinking water does not contain excess chlorine.

Are probiotics still effective when mixed into pelleted feed?

Yes, because it contains Bacillus coagulans which forms heat-resistant spores up to 80°C. The spores will reactivate in the gut. However, it is best to add probiotics after the pelleting process or mix them as a top dressing.
