KUB Free-Range Chicken Probiotic: Performance Evidence in Indonesian Commercial Farms

Free-range chicken and KUB (Kampung Unggul Balitbangtan) farmers often face challenges of high mortality, slow growth, and soaring feed costs. This is where KUB free-range chicken probiotic becomes a science-based solution that is increasingly adopted. This article presents performance data of Biosolution's KUB Free-Range Chicken Probiotic Formula tested in several commercial free-range farms in West Java and Central Java. The results? Up to 40% reduction in mortality, 7-10 day earlier harvest, and an average 15% increase in body weight compared to controls without probiotics.

Mechanism of Action of Lactobacillus acidophilus and Bacillus subtilis

This formula contains two superior bacterial strains: Lactobacillus acidophilus and Bacillus subtilis. Both work synergistically to improve the digestive tract health of chickens.

Lactobacillus acidophilus: Lactic Acid and Anti-Pathogen

Lactobacillus acidophilus is a lactic acid bacterium that produces lactic acid, lowering gut pH, thereby inhibiting the growth of pathogenic bacteria such as Salmonella and E. coli. Additionally, this bacterium produces bacteriocins that directly kill pathogens. In KUB free-range chickens, administration of L. acidophilus has been shown to increase the number of intestinal villi, expanding the nutrient absorption surface, making feed more efficient.

Bacillus subtilis: Enzymes and Biocontrol

Bacillus subtilis produces protease, amylase, and cellulase enzymes that help digest protein, starch, and crude fiber. This is particularly important in free-range chicken feed, which often contains high-fiber ingredients. B. subtilis also produces natural antibiotics (iturin, surfactin) that suppress the growth of harmful fungi and bacteria. With this combination, the KUB Free-Range Chicken Probiotic Formula not only maintains gut health but also improves feed digestibility.

Performance Results in Commercial Farms: Concrete Data

Trials were conducted at three locations: Mr. Samsul's farm in Cianjur (500 KUB chickens), Mitra Tani Farmer Group in Garut (300 regular free-range chickens), and Mrs. Dewi's farm in Tasikmalaya (400 KUB chickens). All implemented a free-range system with standard commercial feed. Treatment: probiotic given at 1 ml per liter of drinking water, 3 times a week in the morning, from DOC until harvest. Parameters measured: mortality, body weight, FCR (Feed Conversion Ratio), and harvest time.

40% Reduction in Mortality

In the control group, average mortality reached 12% during the 70-day rearing period. Meanwhile, in the probiotic group, mortality dropped to 7.2%. This means that out of 1000 chickens, about 48 more survived. This reduction occurred mainly in the chick phase (0-21 days), where L. acidophilus protects the gut from bacterial infection.

15% Increase in Body Weight

The average harvest weight in the probiotic group was 1.15 kg per chicken on day 70, while the control was only 1.0 kg. This 150-gram increase is economically significant. In KUB, standard harvest weight is 0.9-1.0 kg on day 70, but with probiotics it can reach 1.1 kg. Data from Mr. Samsul showed an average weight of 1.18 kg in KUB harvested on day 65.

7-10 Day Earlier Harvest Time

Regular free-range chickens are usually harvested at 70-80 days of age. With probiotics, farmers can harvest earlier: on day 60-63 for regular free-range chickens, and day 60-65 for KUB. This acceleration reduces feed costs and mortality risk due to shorter rearing periods.

Improved FCR (Feed Conversion Ratio)

The FCR in the probiotic group averaged 3.8, while the control was 4.2. This means that to produce 1 kg of meat, 3.8 kg of feed is needed versus 4.2 kg. Feed savings reach 9.5% per chicken. With feed price at IDR 8,000/kg, savings amount to approximately IDR 3,200 per chicken.

Practical Application for Farmers

The KUB Free-Range Chicken Probiotic Formula is designed for easy use. Dosage: 1 ml per liter of drinking water, given 3 times a week (Monday, Wednesday, Friday) in the morning. Ensure drinking water is clean and not high in chlorine (let tap water sit overnight if using PDAM water). Probiotic can be mixed directly into the drinker, or a stock solution can be prepared (1 liter probiotic + 9 liters water) for easier administration.

For optimal results, administer from DOC (first day) until 3 days before harvest. In adult chickens, probiotics remain beneficial for maintaining appetite and health. No need to worry about overdose as bacteria die if overdosed, but still follow recommendations.

Advantages of the Formula Compared to Other Probiotics

Many chicken probiotics contain only one bacterial strain. This formula contains two complementary strains. L. acidophilus excels in the small intestine, while B. subtilis is active in the large intestine and produces enzymes. This combination makes the probiotic effective on various feed types, including fermented feed or forage feed. Additionally, the product is stable at tropical storage temperatures (room temperature), making it practical to store in the coop.

Farmer Testimonials

Mr. Samsul from Cianjur said, "Since using this probiotic, my KUB chickens are more lively, appetite increased, and chick mortality dropped drastically. Harvest is a week earlier." Mrs. Dewi added, "My chickens' average weight is 1.2 kg at 60 days, whereas usually only 1 kg. Feed is also more efficient."

Conclusion

KUB free-range chicken probiotic from Biosolution has been scientifically and empirically proven to improve the performance of free-range and KUB chickens in free-range systems. With reduced mortality, earlier harvest, and feed efficiency, probiotic investment is highly profitable.

FAQ

Is this probiotic safe for free-range chickens that are laying eggs?

Yes, it is safe. Probiotics do not interfere with egg production; they can even improve shell quality and reduce manure odor. Administer at the same dosage.

How long does it take to see results after probiotic administration?

Changes in appetite are usually seen within 3-5 days. Mortality reduction is noticeable after 2 weeks, while growth acceleration is only seen at harvest.

Can probiotics be mixed with medication or vitamins?

It is best to allow a 2-hour interval between probiotic and medication/vitamin administration to avoid inactivation. Probiotics should be given in the morning, medication/vitamins in the afternoon.

Is this probiotic heat-stable during storage?

The product is stable at room temperature (25-30°C) for 6 months. Avoid direct sunlight exposure. Store in a cool, dry place.

For large-scale operations, are there special packaging options?

Yes, packaging is available in 1 liter, 5 liter, and 20 liter sizes. For large farms, we recommend the 20 liter packaging for cost efficiency. Contact us for orders.
