Overcoming Thin Eggshells with Layer Probiotics

Thin and cracked eggshells are a nightmare for layer farmers. Every cracked egg means direct loss and increased risk of bacterial contamination. This problem is often associated with calcium deficiency, heat stress, or impaired nutrient absorption. However, an innovative solution is now available from Biosolution: the Layer Probiotic Formula. This product contains three superior bacterial strains that work synergistically to improve shell quality and production performance. In this article, we will thoroughly examine the causes of thin shells, the role of probiotics, and real data from Indonesian commercial farms.

Why Are Eggshells Thin and Cracked?

Eggshells consist of calcium carbonate (CaCO₃) formed by the shell gland over about 20 hours. Shell quality is influenced by several factors:

• Calcium intake and absorption: Hens need sufficient and optimally absorbable calcium. Digestive tract disorders, such as gut dysbiosis, hinder the absorption of calcium and other minerals.
• Stress: Heat stress, high stocking density, or feed changes trigger corticosterone release, which disrupts calcium metabolism.
• Gut health: An imbalanced gut microbiota reduces nutrient absorption efficiency. Pathogenic bacteria like Salmonella can also infect the reproductive tract.
• Hen age: As hens age, the shell gland's ability to form thick shells declines.

Data from the Ministry of Agriculture shows that thin shells cause losses of up to 5-7% of total egg production in Indonesia. Therefore, appropriate intervention is essential.

The Role of Probiotics in Improving Shell Quality

Probiotics are live microorganisms that provide health benefits to the host. In laying hens, probiotics work through several mechanisms:

• Increasing beneficial bacterial populations in the gut, reducing competition with pathogens.
• Improving intestinal villi morphology, increasing the surface area for nutrient absorption, including calcium and phosphorus.
• Producing enzymes and organic acids that aid feed degradation and mineral absorption.
• Lowering gut pH, making calcium more soluble and absorbable.

The Layer Probiotic Formula from Biosolution contains three specially selected strains:

• Lactobacillus bulgaricus: Produces lactic acid that suppresses the growth of Salmonella and other pathogenic bacteria. Lactic acid also helps acidify the gut, increasing calcium bioavailability.
• Lactobacillus acidophilus: This strain is known to adhere to the intestinal epithelium and produce bacteriocins, stabilizing the gut microbiota. With a healthy gut, calcium absorption becomes optimal.
• Bacillus coagulans: The advantage of this strain is its ability to form spores resistant to heat and stomach acid. The spores germinate in the small intestine and produce protease, lipase, and phytase enzymes that help release bound minerals. B. coagulans also increases the expression of calcium-binding proteins (calbindin) in intestinal cells.

These three strains work synergistically to ensure maximum calcium absorption, resulting in thicker and more uniform eggshells.

Commercial Farm Trial Results: Data on Shell Thickness Improvement

To prove the effectiveness of the Layer Probiotic Formula, Biosolution conducted a trial at a commercial farm in East Java with a population of 10,000 ISA Brown laying hens aged 45 weeks. Parameters measured included shell thickness, percentage of cracked eggs, and egg production.

Methodology

• Treatment group: 5,000 hens received 1 ml/liter of probiotic in drinking water every morning for 8 weeks.
• Control group: 5,000 hens without probiotics.
• Feed: Same for both groups (standard farm feed).

Results

The data show that probiotic supplementation significantly increased shell thickness and reduced cracked egg rates. An increase in egg production was also observed, consistent with the benefits of probiotics in maintaining production persistence.

The mechanism behind this improvement is the optimization of calcium absorption due to improved gut health. With a healthy gut, hens can utilize dietary calcium more efficiently. Additionally, probiotics reduce oxidative stress and inflammation in the reproductive tract, allowing the shell gland to function optimally.

How to Apply the Layer Probiotic Formula on Your Farm

Applying the Layer Probiotic Formula is very easy. Here is a practical guide:

1. Dosage: 1 ml per liter of drinking water.
2. Frequency: Daily during the production period.
3. Time: Administer in the morning when hens are actively drinking. Ensure water is clean and free of excess chlorine (chlorine can kill probiotics).
4. Duration: Start from when hens enter the production period (18 weeks) until the end of the cycle.

For optimal results, combine with good feed management, especially the availability of particulate calcium (grit) in the afternoon. Also ensure good barn ventilation to reduce heat stress.

Conclusion

Thin and cracked eggshells can be addressed through a gut health approach. The Layer Probiotic Formula from Biosolution, containing Lactobacillus bulgaricus, Lactobacillus acidophilus, and Bacillus coagulans, has been proven to increase shell thickness by up to 12.5% and reduce cracked eggs by up to 56.3% in commercial farm trials. Additionally, egg production increased by 4.2%. With probiotics, farmers not only reduce losses from cracked eggs but also improve overall productivity.

FAQ

Is it safe to give probiotics every day?

Yes, probiotics are safe to give daily because the strains used are non-pathogenic microbes that have been tested for safety. The dosage of 1 ml/liter of drinking water is adjusted to maintain gut microbiota balance without side effects.

How long does it take to see shell improvement?

Improvement usually begins to be seen after 2-3 weeks of regular administration. In the farm trial, significant shell thickness increase was detected at week 4.

Can probiotics be combined with antibiotics?

It is best to avoid simultaneous administration with antibiotics because antibiotics can kill probiotics. Allow a minimum of 4 hours after antibiotic administration, or consult a veterinarian.

How should the Layer Probiotic Formula be stored?

Store in a cool, dry place, away from direct sunlight. Ideal storage temperature is 15-25°C. After opening, use within 30 days.

Is this product registered with the Ministry of Agriculture?

Yes, this product is registered and meets the standards for feed additives in Indonesia. Registration information can be found on the packaging.
