Explore our bio-engineered, strain-stabilized pet food bases, enzymatic flavor enhancers, and functional kibble components optimized for B2B global sourcing.
The global demand for pet digestive health solutions has experienced exponential growth. Pet parents across North America, Europe, and the Asia-Pacific region are increasingly seeking preventive healthcare formulations. Gut microflora imbalances in dogs and cats directly correlate with acute gastrointestinal distress, inflammatory bowel disease (IBD), dermatological allergic manifestations, systemic low-grade inflammation, and compromised immune response. To address these complex physiological challenges, pet brand owners, contract packagers, and distributors require wholesale manufacturing partners capable of delivering validated, clinically documented probiotic strains that remain biologically viable throughout the product shelf life.
Traditional pet food manufacturing relies heavily on high-temperature, high-pressure extrusion. Standard un-encapsulated probiotic bacteria—such as non-spore-forming Lactobacillus and Bifidobacterium species—suffer near-total thermal degradation when subjected to temperatures exceeding 65°C. Consequently, supplying true, functional pet probiotics wholesale demands state-of-the-art bio-preservation mechanisms, microencapsulated protective shells, thermal-stable sporeformers, and specialized post-extrusion cold-dosing spraying systems.
Dongguan Petra Pet Co., Ltd., is a professional enterprise that engaged in pet food research and development, production and sales, combining with healthy breeding research and care for pets.
Our products are healthy and natural with high quality, which is animal protein and diverse dietary fibers balanced, adding fruits, vegetables and diverse vitamins, that is the division of each component is more suitable for the health and growth of pets. In order to meet different clients demands, we absorb their comments and suggestions and then we constantly upgrade our recipe scientifically on our classical manufacturing experience basis.
Our factory covers an area of over 30,000 square meters, of which include more than 20,000 square meters of standardized production workshop and advanced equipment, the annual output up to 60,000 tons, which can meet the demands of 500,000 dogs and cats in a year. In order to make our products health and quality assurance, we adopt the most advanced pet food production equipment.
To overcome gastric juice acidity (pH 1.5 - 2.5) and bile salt degradation in carnivorous digestive systems, our biochemical laboratory has engineered a proprietary Triple-Layer Microencapsulation Technology. This innovation forms the cornerstone of our China wholesale pet probiotic manufacturing advantage.
High-density viable strains (such as Bacillus coagulans, Enterococcus faecium, and Lactobacillus acidophilus) bound within a protective sodium alginate and prebiotic oligosaccharide network that nurtures bacterial recovery during rehydration.
A hydrophobic lipid barrier prevents water activity (aW) fluctuations from penetrating the core, guaranteeing long-term shelf stability at ambient storage conditions without requiring refrigerated cold chains.
pH-responsive natural shellac/pectin complex remains insoluble in stomach acid, dissolving rapidly only upon reaching the alkaline intestinal tract (pH 6.8 - 7.4) for targeted localized release.
| Probiotic Strain Specie | Target Health Function | Thermal Survival Limit | Gastric Acid Survival Rate | Ideal Application Method |
|---|---|---|---|---|
| Bacillus coagulans (BC-08) | Sporeformer; Diarrhea reduction, firm stool formulation | Up to 90°C (10 mins) | 99.2% Viability | Extruded Kibble, Baked Treats, Powders |
| Enterococcus faecium (EF-12) | Intestinal flora rapid balancing, pathogen exclusion | Up to 75°C (Microencapsulated) | 94.6% Viability | Wet Canned Paste, Soft Chews, Sachets |
| Lactobacillus acidophilus (LA-05) | Lactic acid secretion, nutrient absorption optimization | Up to 65°C (Microencapsulated) | 91.8% Viability | Freeze-Dried Meat Sprinkles, Toppers |
| Bifidobacterium animalis (BA-11) | Colonic health, Short-Chain Fatty Acid (SCFA) boost | Up to 65°C (Microencapsulated) | 93.1% Viability | Veterinary Powders, Oil Drops |
As a full-service ODM/OEM pet nutrition powerhouse, we combine high-purity animal proteins (chicken, duck, tuna, beef, cod) with fiber-rich botanical vectors (pumpkin, sweet potato, apple dice) and scientifically validated postbiotics, prebiotics, and probiotics. We provide end-to-end white-label solutions tailored to your market positioning.
Leveraging post-extrusion vacuum coating technology, we apply lipid-encapsulated live probiotics alongside palatability enhancers (enzymolysis chicken powder) directly onto kibble surfaces, maintaining active CFU integrity without heat degradation.
Integrating heat-stable sporeformers (*Bacillus* series) into moist patés, mousses, and fish broths. Our automated retort sterilization protocols ensure microflora stability while maintaining optimum physical texture.
Utilizing high-vacuum sublimation freeze-drying below -40°C, preserving 100% of native enzyme activities and delicate strain bio-activity in pure raw meat substrates.
Strain target selection, CFU concentration scaling & palatability adjustment.
Bench-scale extrusion, microencapsulation verification & stability testing.
Third-party microbiology quantitative analysis & gut acid simulation pass.
Automated batch processing across 20,000m² cleanroom workshops.
Customized moisture-proof packaging, international customs clearance & delivery.
Our Hebei and Dongguan manufacturing hubs feature fully automated micro-dosing systems that guarantee batch-to-batch probiotic concentration variances stay under ±1.5%. Micro-ingredient addition is monitored via computer vision and IoT weight-sensors, eliminating human error during high-density CFU inoculation.
By securing direct upstream contracts for fresh animal proteins, vegetable fiber substrates, and pure strain cultures, our enterprise guarantees price stability despite global commodity market volatility. Our annual production capacity of 60,000 tons provides buffer capacity for emergency customer scale-ups.
Compliance is paramount in wholesale pet food supply chains. We operate strict Quality Assurance (QA) and Quality Control (QC) protocols certified under ISO 22000, HACCP, GMP+, and FDA registration frameworks. Every production batch of probiotic pet treats, kibbles, or canned formulas undergoes extensive analytical verification prior to warehouse release.
Plating assays confirm active viable cell counts match container label guarantees at manufacture and through simulated shelf-life periods.
Zero tolerance testing for Salmonella, E. coli, Listeria, and mycotoxins using rapid real-time PCR amplification technology.
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) screens for trace Lead, Arsenic, Cadmium, and Mercury levels far below EU & AAFCO limits.
Strict moisture and water activity controls (aW < 0.65 for dry products) to prohibit latent bacterial strain reactivation prior to ingestion.
Complete your product lineup with our specialized wet cans, limited-ingredient sensitivity diets, and freeze-dried raw pet treats.
