Broiler Probiotic FCR: 8% Improvement in Commercial Farm Results

Broiler farmers in Indonesia continue to face high feed cost pressures and consumer demands for antibiotic-free chicken meat. One proven effective solution is the use of broiler probiotics to improve FCR (Feed Conversion Ratio) and ADG (Average Daily Gain). The Broiler Probiotic Formula from Biosolution, containing three superior bacterial strains, has been tested in commercial farms and shown FCR improvements of 8–12% and ADG increases of 5–10%. This article will discuss the mechanism of action, performance results, and technical application of this probiotic.

Mechanism of Probiotics in Improving FCR and ADG

Broiler probiotics work through several synergistic mechanisms to improve feed efficiency and growth. The Broiler Probiotic Formula contains Lactobacillus acidophilus, Bacillus subtilis, and Bacillus coagulans, each with specific roles.

Competitive Exclusion

Probiotic bacteria compete with pathogens such as E. coli, Salmonella, and Clostridium for nutrients and adhesion sites in the intestinal wall. By dominating the gut microflora population, probiotics prevent pathogen colonization that can cause diarrhea or enteritis, thus optimizing nutrient absorption.

Lactic Acid Production and Gut pH Reduction

Lactobacillus acidophilus produces lactic acid, which lowers gut pH. This acidic environment is unfavorable for gram-negative pathogens while increasing the activity of host digestive enzymes. Lower gut pH also stimulates pancreatic enzyme secretion, improving protein and fat digestibility.

Digestive Enzymes from Bacillus

Bacillus subtilis and Bacillus coagulans produce protease, amylase, and lipase enzymes that help break down feed into simpler molecules. These enzymes improve feed digestibility, especially in corn and soybean meal-based rations common in Indonesia. Thus, more energy and protein are absorbed, supporting higher ADG.

Immunomodulation

Probiotics stimulate the production of immunoglobulin A (IgA) in the intestinal mucosa, strengthening local defenses. Chickens with good gut immunity are more resistant to subclinical infections that often go unnoticed but drain energy. Energy that would be used to fight infection can be redirected to growth, improving FCR.

Performance Results in Indonesian Commercial Farms

Trials of the Broiler Probiotic Formula were conducted in five medium-scale broiler farms in West Java and East Java over a 35-day rearing period. Parameters measured included FCR, ADG, mortality, and harvest weight. The following is a summary of the results.

FCR Improvement of 8–12%

In the treatment group receiving 1 ml/L of drinking water daily during starter, then 3 times a week during grower-finisher, the average FCR was recorded at 1.45–1.50, while the control without probiotic reached 1.60–1.70. This means each kilogram of live weight was produced with 0.1–0.2 kg less feed. With a feed price of IDR 8,000/kg, feed cost savings per bird reached IDR 1,600–3,200.

ADG Increase of 5–10%

Daily ADG in the probiotic group ranged from 48–52 grams/bird/day, compared to 44–48 grams/bird/day in the control. This increase was statistically significant (P<0.05). Harvest weight at 35 days reached 1.8–2.0 kg, 100–200 grams higher than the control.

Low Mortality

Mortality in the probiotic group was recorded below 3%, lower than the control which reached 5–7%. The reduction in mortality was mainly due to decreased cases of colibacillosis and necrotic enteritis, thanks to the competitive exclusion effect and lactic acid production.

No Antibiotic Residues

Because the probiotic is used as a replacement for Antibiotic Growth Promoters (AGP), chicken meat from the treatment group was proven free of antibiotic residues when tested in the laboratory. This meets food safety standards and opens opportunities for premium markets.

Application Method of Broiler Probiotic Formula

For optimal results, the probiotic must be applied correctly. Here are technical guidelines from Biosolution.

Via Drinking Water

Dosage of 1 ml/L of drinking water is given in the morning after feeding. Ensure drinking water is clean and does not contain excess chlorine (let water stand for 1 hour if using chlorinated water). During the starter phase (days 1–14), give daily. During the grower-finisher phase (days 15–35), give 3 times a week (Monday, Wednesday, Friday).

Via Feed

If more practical, the probiotic can be mixed with feed at a dosage of 2 ml/kg feed. Spray the probiotic solution evenly onto the feed, then mix. Administer immediately after mixing. For pelleted feed, Bacillus coagulans with heat-resistant spores ensures bacterial viability is maintained.

Timing of Administration

Morning administration is recommended because chickens tend to drink more after eating. Ensure sufficient drinkers and that water is not contaminated. Do not mix the probiotic with antibiotics or disinfectants at the same time; allow a minimum 2-hour interval.

Advantages of Biosolution Broiler Probiotic Formula

Compared to other probiotics on the market, the Broiler Probiotic Formula has several advantages:

• Combination of 3 synergistic strains: Lactobacillus acidophilus lowers pH, Bacillus subtilis produces enzymes, and Bacillus coagulans provides thermal stability. They work in different gut segments, covering the small intestine to the large intestine.
• Heat resistance: Bacillus coagulans forms spores that withstand temperatures up to 80°C, making it safe to mix in feed pelleting processes.
• Field-proven effectiveness: Data from Indonesian commercial farms shows consistent results, not just laboratory trials.
• Practical: Can be administered via drinking water or feed, flexible for various farm scales.

Conclusion

The use of broiler probiotics such as the Biosolution Broiler Probiotic Formula has proven effective in improving FCR by 8–12% and ADG by 5–10% in Indonesian commercial farms. Through mechanisms of competitive exclusion, lactic acid production, digestive enzymes, and immunomodulation, this probiotic is a safe and profitable AGP-free solution. For maximum results, follow the recommended dosage and frequency. Interested in trying? Consult your farm needs via our WhatsApp or see product details Broiler Probiotic Formula.
