Aquaculture Lactobacillus Casei | Acid-Resistant Coating 30B CFU/g, Vibriosis Control

Lactobacillus casei is a whole-genome sequenced animal feed probiotic that enhances livestock health and production performance by regulating gut microbiota, boosting immunity, and improving feed utilization.
Keywords: Lactobacillus casei, animal probiotics, feed additives, gut health.

Why Choose Our Lactobacillus Casei?

Stress Resistance

Survives gastric acid (pH 2.5) and bile salts (0.3%) with >90% intestinal survival rate.

Safety

FDA GRAS-certified, zero risk of antibiotic resistance gene transfer.

Innovative Technology

Triple-layer freeze-drying encapsulation ensures >85% viability after 12 months of storage.

Gut Barrier Enhancement

Stimulates mucin secretion and repairs intestinal mucosal damage (e.g., 60% diarrhea reduction in piglets).

Digestibility Improvement

Secretes cellulase and protease, lowering feed conversion ratio (FCR reduced by 0.3-0.5).

Growth Promotion

Synthesizes B vitamins and short-chain fatty acids (SCFAs), increasing daily weight gain by 8-12%.

Application Scenarios

Aquaculture

Disease Prevention: Strain YFI-5 inhibits viral invasion (e.g., reduces mortality in crucian carp with hemorrhagic hematopoietic necrosis, patent-supported data).

Growth Optimization: Enhances feed utilization and shortens growth cycles via gut microbiota modulation.

Livestock Farming

Diarrhea Control: Strain PLBS004 reduces diarrhea and mortality in weaned piglets while elevating antioxidant enzyme activity.

Fermented Feed: Compatible with antibiotics in complete feed formulations for rapid, healthy swine growth.

Extended Shelf Life: Freeze-drying technology supports room-temperature storage, ideal for industrial feed production.

Features

Appearance: Brown powder with mild fermented odor.

Storage Method

Store in a cool, dry place.

Workshop

FAQ

Q: Advantages over Bacillus subtilis?

A: L. casei directly colonizes the gut for faster action (24-48 hours), while B. subtilis requires spore germination. Synergistic use (1:1 ratio) is recommended.

Q: Compatibility with antibiotics?

A: Avoid concurrent use with broad-spectrum antibiotics (e.g., chlortetracycline). For therapeutic antibiotics (e.g., amoxicillin), administer 12 hours apart.

Q: How to verify efficacy?

A: Three-step validation: ① Test fecal pathogen counts; ② Monitor feed intake; ③ Calculate FCR after 7-day weight measurement.
