Probiotic Schedule for KUB Free-Range Chickens by Growth Phase

Probiotics for free-range and KUB chickens in free-range systems are now a mainstay solution for modern farmers. By using the right KUB free-range chicken probiotics, you can accelerate growth, increase immunity, and reduce mortality. However, for maximum benefits, probiotic administration must be adjusted to the growth phase. This article thoroughly discusses the probiotic schedule per phase, from DOC to harvest, specifically for free-range and KUB chickens raised in free-range systems.

Why Are Probiotics Important for KUB Free-Range Chickens?

KUB (Kampung Unggul Balitbangtan) free-range chickens are selected chickens with higher meat and egg production potential than ordinary free-range chickens. However, free-range rearing systems make them susceptible to pathogens from the environment. This is where probiotics play a role. Probiotics are beneficial live microorganisms, such as Lactobacillus acidophilus and Bacillus subtilis, that help balance the gut microflora.

Lactobacillus acidophilus produces lactic acid that inhibits the growth of pathogenic bacteria like Salmonella and E. coli. Meanwhile, Bacillus subtilis produces enzymes that aid feed digestion and also has antimicrobial effects. The combination of these two bacteria in the Probiotic Formula for Free-Range & KUB Chickens from Biosolution has been proven to improve feed conversion ratio (FCR) and accelerate harvest time. With regular administration, chickens become healthier, appetite increases, and mortality drops drastically.

Probiotic Schedule for Starter Phase (DOC – 4 Weeks)

The starter phase is a critical period in a chicken's life. DOC (Day Old Chick) have an immature immune system, making them vulnerable to infections. Administering probiotics from the start helps establish a population of good bacteria in the gut, making chickens more resistant to stress and disease.

Dosage and Frequency

• Dosage: 1 ml per liter of drinking water.
• Frequency: 3 times per week (e.g., Monday, Wednesday, Friday).
• Time: Morning, when chickens start actively drinking.

Application Method

Mix the probiotic into clean drinking water. Ensure the water does not contain excess chlorine as it can kill probiotic bacteria. Let it sit for 10-15 minutes before giving. Change water every 4-6 hours to maintain freshness.

Benefits in the Starter Phase

• Prevents diarrhea and digestive disorders.
• Increases resistance to bacterial infections.
• Aids nutrient absorption from starter feed (usually 20-22% protein).

In this phase, farmers often complain of sudden death due to colibacillosis or salmonellosis. With probiotics, this risk can be reduced. Research shows that administering Lactobacillus acidophilus probiotics to DOC free-range chickens can reduce mortality by up to 30%.

Probiotic Schedule for Grower Phase (4 – 12 Weeks)

Entering the grower phase, chickens become more active and forage in the free-range area. During this phase, bone and muscle growth is rapid. Probiotics are still needed to maintain digestive tract health and optimize nutrient absorption.

Dosage and Frequency

• Dosage: 1 ml per liter of drinking water.
• Frequency: 3 times per week (consistent).
• Time: Morning.

Feed Adjustment

In this phase, chickens are usually given feed with 16-18% protein. Probiotics help break down crude fiber from supplementary feed like rice bran or forage, making energy more available for growth. Bacillus subtilis produces protease, amylase, and cellulase enzymes that improve feed digestibility.

Benefits in the Grower Phase

• Increases average daily gain.
• Improves feed conversion ratio (FCR) for better efficiency.
• Reduces manure odor due to better nutrient absorption.

In this phase, KUB free-range chickens given probiotics regularly can reach a weight of 800-1000 grams by week 8, 1-2 weeks faster than without probiotics. Additionally, chickens are more active and rarely suffer from respiratory diseases.

Probiotic Schedule for Finisher Phase (>12 Weeks)

The finisher phase is the pre-harvest preparation period. The main goal in this phase is to maximize final weight and maintain meat quality. Probiotics are still given until 1 week before harvest to ensure optimal gut health.

Dosage and Frequency

• Dosage: 1 ml per liter of drinking water.
• Frequency: 3 times per week.
• Time: Morning.

Special Notes

• Stop probiotic administration 7 days before harvest to avoid residues (although probiotics are safe, some markets require a withdrawal period).
• Ensure drinking water is always available and clean.

Benefits in the Finisher Phase

• Increases slaughter weight (e.g., 1.2-1.5 kg at week 12).
• Improves carcass quality, meat is denser and lower in fat.
• Reduces stress during catching and transport.

With consistent probiotic administration, KUB free-range chickens can be harvested at 10-12 weeks of age with ideal weight, 2 weeks faster than without probiotics. This is certainly beneficial for farmers as it shortens the rearing period and reduces feed costs.

Tips to Maximize Probiotic Effectiveness in KUB Free-Range Chickens

For probiotics to work optimally, consider the following:

1. Water Quality: Use clean, chlorine-free water. If water contains chlorine, let it sit overnight or use vitamin C to neutralize it.
2. Consistency: Administer probiotics regularly according to schedule. Do not skip, especially in the starter phase.
3. Cage Hygiene: Probiotics do not replace hygiene management. Ensure the free-range cage remains clean and dry.
4. Quality Feed: Probiotics work synergistically with feed. Provide feed according to growth phase.
5. Avoid Antibiotics: If antibiotics are necessary, allow at least a 2-hour gap after probiotics. Antibiotics can kill beneficial bacteria.

By applying the tips above, you will experience maximum benefits from KUB free-range chicken probiotics.

Conclusion

Proper administration of probiotics for KUB free-range chickens according to the growth phase is the key to successful free-range chicken farming. From the starter, grower, to finisher phases, probiotics help improve health, accelerate growth, and reduce mortality. The Probiotic Formula for Free-Range & KUB Chickens from Biosolution, containing Lactobacillus acidophilus and Bacillus subtilis, is the right choice for a productive and efficient farm.

FAQ

1. Are probiotics safe for KUB free-range chickens?

Yes, probiotics are very safe. The bacteria used, such as Lactobacillus acidophilus and Bacillus subtilis, are microorganisms naturally found in the chicken's digestive tract. There are no negative side effects if given according to dosage. In fact, probiotics help suppress the growth of pathogenic bacteria, making chickens healthier.

2. How long does it take to see results from probiotics?

Changes are usually visible within the first 1-2 weeks. Chickens will be more active, appetite increases, and droppings become firmer. Body weight gain becomes significant from week 4 to week 8. For maximum results, administer probiotics regularly throughout the rearing period.

3. Can probiotics be mixed with medication or vitamins?

It is best not to mix directly with antibiotics. Allow at least a 2-hour gap. For vitamins, they can be mixed as long as they do not contain chlorine or antimicrobial ingredients. If in doubt, give probiotics in the morning and vitamins in the afternoon.

4. Should the probiotic dosage be increased when chickens are sick?

No. The dosage remains 1 ml per liter of water. When chickens are sick, probiotics help strengthen immunity, but they are not a substitute for medication. If there are symptoms of serious illness, consult a veterinarian and give probiotics as support.

5. How should probiotics be stored to remain active?

Store probiotics in a cool, dry place, away from direct sunlight. Ideal storage temperature is between 4-25°C. After opening, use within 30 days. Do not freeze as it can damage bacterial cells.
