Probiotik Ayam Kampung KUB: Cost Comparison with Antibiotics in Free-Range Systems

Free-range KUB (Kampung Unggul Balitbangtan) chicken farmers often face a dilemma: using antibiotics to prevent disease, or switching to more natural probiotics? Both aim to maintain chicken health, but in terms of cost and long-term impact, which is more profitable? This article thoroughly examines the cost comparison between antibiotics and probiotics for free-range KUB chickens, complete with data and product recommendations from Biosolution.

Why Antibiotics Are Being Abandoned by Modern Farmers

Antibiotics have long been a mainstay for farmers to control bacterial infections in free-range chickens. However, their overuse leads to bacterial resistance, residues in meat, and negative impacts on chicken gut microflora. The Indonesian government, through Permentan No. 14/2017, even prohibits the use of antibiotics as growth promoters (AGP) in animal feed. Consequently, farmers must seek safe and effective alternatives. This is where probiotics for KUB chickens come in as a solution.

Probiotik Ayam Kampung KUB: Mechanism and Advantages

Probiotics are live microorganisms that provide health benefits to the host when administered in adequate amounts. In KUB chickens, probiotics work by:

Balancing Gut Microflora

Probiotics such as Lactobacillus acidophilus produce lactic acid that suppresses the growth of pathogenic bacteria (e.g., Salmonella and E. coli). Bacillus subtilis produces protease, amylase, and cellulase enzymes that aid feed digestion, thereby improving nutrient absorption.

Boosting Immunity

Beneficial microbes stimulate antibody production and immune cells, making chickens more resistant to stress and disease attacks.

Accelerating Growth

With more efficient digestion, chickens reach slaughter weight faster. In free-range systems, probiotics also help chickens adapt to natural feed in the field.

Cost Comparison: Antibiotics vs Probiotics for KUB Chickens

Below is a cost analysis for 100 free-range KUB chickens over a 70-day rearing period (until harvest).

Conventional Antibiotic Costs

• Type: Oxytetracycline (powder form, dose 1 g/10 kg BW/day)
• Average price: Rp 50,000 per 100 grams
• Dose per chicken per day: 0.1 g (assuming 1 kg BW)
• Total dose for 100 chickens x 70 days = 700 grams
• Antibiotic cost: 7 x Rp 50,000 = Rp 350,000

This does not include additional costs for managing side effects such as digestive disturbances and decreased appetite that often occur after antibiotic administration.

Probiotic Formula for Free-Range & KUB Chickens (Biosolution) Costs

• Product: Probiotic Formula for Free-Range & KUB Chickens
• Content: Lactobacillus acidophilus and Bacillus subtilis
• Dose: 1 ml per liter of drinking water, 3 times a week (Monday, Wednesday, Friday)
• Daily water requirement for 100 chickens: ~20 liters
• Weekly probiotic usage: 3 days x 20 liters x 1 ml/liter = 60 ml
• Total usage over 10 weeks (70 days): 600 ml
• Product price: Rp 75,000 per 500 ml
• Probiotic cost: 1.2 bottles x Rp 75,000 = Rp 90,000

Cost difference: Rp 260,000 cheaper using probiotics.

Additional Benefits of Probiotics

• Lower mortality: Probiotics reduce chick mortality by 5-10% (compared to antibiotics which only suppress infections without improving immunity).
• Better feed conversion: With enzymes from Bacillus subtilis, FCR (Feed Conversion Ratio) drops by 0.1-0.2 points, saving feed costs by about 5-10%.
• Higher selling price: Probiotic-fed chickens are free from antibiotic residues, allowing them to be sold at a premium price (e.g., Rp 5,000-10,000/kg more expensive).

Case Study: Farmer in West Java

Mr. Agus, a KUB chicken farmer in Cianjur, switched from antibiotics to probiotics in 2023. With 500 free-range chickens, he reported:

• Mortality dropped from 15% to 5%.
• Harvest weight (70 days) increased from 1.2 kg to 1.4 kg.
• Feed costs decreased by 12% due to improved FCR.
• No cases of diarrhea or respiratory diseases.

"I was initially hesitant because probiotics are more expensive per bottle, but the usage is small and the results are amazing. It's more cost-effective overall," he said.

How to Use Probiotics for Free-Range KUB Chickens

The Probiotic Formula for Free-Range & KUB Chickens product is very easy to apply:

1. Mix 1 ml of probiotic per liter of drinking water.
2. Administer 3 times a week (in the morning) for optimal results.
3. Ensure drinking water is clean and not high in chlorine (let tap water sit for 1 hour before mixing).

For free-range chickens, probiotics can also be mixed into fermented feed or given directly through easily accessible drinking water.

Why Probiotics Are More Economical in the Long Run?

In addition to lower direct costs, probiotics provide indirect benefits:

• Reduced treatment costs: Chickens are healthier, rarely sick.
• Faster harvest: Chickens can be harvested 3-5 days earlier.
• Better meat quality: Meat is denser, lower in fat, and free from fishy odor.

Conclusion

Probiotics for free-range KUB chickens have proven to be more cost-effective than antibiotics, with a difference of up to 74% cheaper for a 70-day program. Moreover, probiotics increase productivity, lower mortality, and produce residue-free products with higher market value. Switching to probiotics is a smart investment for sustainable farming.
