Probiotics and postbiotics for companion animals
Species-specific probiotics and heat-stable postbiotics for dog and cat gut health.
1 · What it gives
The precision probiotics and postbiotics sector for companion animals (dogs and cats) is one of the most commercially attractive and technology-intensive segments of the pet wellness industry. Driven by the global pet-humanisation trend — where dogs and cats are treated as family members — pet food and veterinary supplement innovation is undergoing radical transformation. Owners apply the same quality standards to their pets’ nutrition as to their own, focusing on preventive medicine, digestive health, immune support, allergy management and emotional balance via the gut-brain axis.
Key directions of the sector:
- Precision species-specific probiotics: Live bacterial strains isolated from healthy dogs and cats (Enterococcus faecium SF68, Lactobacillus acidophilus DSM 13241, Bifidobacterium animalis AH1206). These colonise the species-specific GI tract, suppress pathogens (Clostridium, Salmonella), stimulate IgA production and normalise stool during stress and dietary changes.
- Innovative heat-stable postbiotics: Non-viable microbial cells and/or their metabolites (short-chain fatty acids — acetate, butyrate, propionate — as well as bacteriocins and vitamins). Unlike live probiotics, postbiotics survive extrusion temperatures (>120 °C), have unlimited shelf life and integrate directly into dry kibble at the mixing stage.
- Microencapsulation and vacuum coating technology: Fat-based microencapsulation of live probiotics for gastric protection, followed by vacuum coating onto extruded kibble (Dinnissen process) that seals bacteria deep inside kibble pores away from oxygen.
- Gut-brain axis and behavioural health: Probiotic and postbiotic formulations targeting the gut-brain axis in pets to manage anxiety, stress-induced diarrhoea and cognitive function in ageing animals.

Cross-cutting technologies:
- Species-specific strain screening: Bacteria from human or bovine GI tracts cannot effectively adhere to canine/feline intestinal epithelium. Host-specific screening panels test adhesion to dog intestinal epithelial cell lines, resistance to canine-specific bile acids and gastric pH (~2.0), and full genome sequencing to exclude pathogenicity islands and AMR plasmids.
- Vacuum coating technology: Liquid fat-probiotic mixture is sprayed onto kibble under vacuum (0.01 MPa); when vacuum is released, atmospheric pressure forces the mixture deep into kibble pores, sealing probiotics inside and excluding oxygen.
- Postbiotic heat-inactivation kinetics: Controlled thermal inactivation (75–85 °C, 30 min) or high-frequency ultrasonication destroys cell viability while preserving cell-wall integrity (immunogenic peptidoglycans, teichoic acids) and metabolite structure (SCFAs).

Purina FortiFlora market leader, NASC Quality Seal, Hill’s microbiome research#
- Purina FortiFlora: Nestlé Purina’s probiotic supplement based on Enterococcus faecium SF68 is the best-selling and most veterinarian-recommended probiotic product in the US, proven effective in reducing diarrhoea in dogs and cats under stress. Microencapsulated in a protein-polymer protective shell.
- NASC Quality Seal: The National Animal Supplement Council conducts independent audits of pet supplement manufacturers. The gold NASC Quality Seal on packaging is the primary trust signal for US consumers.
- Hill’s Pet Nutrition Science Center: Conducts large-scale clinical studies on canine and feline gut microbiomes. The Biomome diet line uses targeted prebiotic fibres for precision modulation of GI microbiota.
- FDA CVM oversight: Probiotics for pets are regulated as animal drugs or feeds depending on claims; most products are marketed as nutritional supplements with structure-function claims under AAFCO guidelines.
European Union
The European Union is the birthplace of strict feed-additive regulation and leads in probiotic gut-brain axis research for companion animals.
EFSA Regulation 1831/2003, Novonesis gut health, Lallemand yeast probiotics, ADM Protexin Pro-Kolin#
- EFSA strict registration: Unlike the US where probiotics sell as supplements without rigorous clinical proof, the EU requires a multi-year registration under EC 1831/2003, with mandatory proof of species safety, genome stability (absence of AMR genes) and therapeutic efficacy.
- Novonesis (formerly Chr. Hansen): Danish bioscience leader supplying EFSA-certified Enterococcus faecium and Pediococcus acidilactici strains for dogs and cats. GalliPro Fit is their flagship spore-forming probiotic for feed extrusion tolerance.
- Lallemand Animal Nutrition: French-Canadian specialist in yeast and lactic acid bacteria probiotics with patented membrane-protection drying technology. Lalprobi and Bactocell lines are widely used in European pet food.
- ADM Protexin (UK): Manufacturer of Pro-Kolin — a synbiotic paste with pectin and kaolin that is the European standard for acute GI distress in companion animals. Combines probiotics with prebiotic fibres in a high-adhesion paste format.
China
China is experiencing a boom in premium pet food, driven by urban Gen-Z cat owners, while developing domestic biotech production of species-specific probiotics for the Asian region.
Pet premiumisation boom, CAAS metagenomic studies, domestic probiotic manufacturing#
- Premium pet food surge: Urban Chinese consumers (Gen Z) are rapidly adopting cats, creating enormous demand for functional treats and probiotic-enriched foods targeting coat quality, litter-box odour reduction and digestive health.
- CAAS metagenomic research: The Chinese Academy of Agricultural Sciences (CAAS), including its military veterinary institutes, is building detailed metagenomes of local dog breeds (chow chow, Tibetan mastiff), identifying unique Bifidobacterium strains with enhanced affinity to local diets.
- Domestic bio-factories: Large Chinese ingredient manufacturers in Shandong and Zhejiang provinces are building dedicated freeze-dried veterinary probiotic plants for ASEAN export. GenScript ProBio offers contract development of veterinary probiotic strains.
- Regulatory framework: MARA (Ministry of Agriculture and Rural Affairs) oversees probiotic feed additive registration under the 2019 Feed Management Regulations, requiring strain-level identification and safety data.

7 · Tech stack & innovations
Pet probiotic and postbiotic development rests on three technology pillars: host-specific anaerobic strain cultivation, microencapsulation in hydrocolloid matrices, and industrial vacuum-coating onto feed.
Host-specific strain isolation:
- Bacteria from human or bovine sources fail to adhere to canine/feline GI epithelium due to differences in mucosal receptor (glycoprotein) structure.
- Screening workflow: faecal sampling from healthy, antibiotic-naive animals → in vitro adhesion assay on dog intestinal epithelial cell lines → bile/acid resistance testing → whole-genome sequencing for pathogenicity/AMR plasmid exclusion.
Microencapsulation and vacuum coating:
- Live bacteria cannot survive hot extrusion (>120 °C). The vacuum coating process applies probiotics after extrusion:
- Dry kibble is manufactured via hot extrusion without bacteria.
- Cooled kibble enters a Dinnissen vacuum coater.
- Vacuum (0.01 MPa) is drawn; a warm fat-bacterial-palatant blend is sprayed onto kibble.
- Vacuum release forces the blend deep into kibble pores, sealing probiotics inside away from oxygen.
- Microencapsulation in hydrogenated coconut fat (melting point 36 °C) adds a water-impermeable protective layer around each bacterial cell.
- Live bacteria cannot survive hot extrusion (>120 °C). The vacuum coating process applies probiotics after extrusion:
Postbiotic production:
- After fermentation, the bacterial culture is subjected to controlled thermal inactivation (75–85 °C, 30 min) or high-frequency ultrasonication to destroy viability while preserving cell-wall integrity and SCFA metabolite structure.
- The resulting postbiotic concentrate is spray-dried, yielding a shelf-stable powder that survives extrusion and has unlimited shelf life.
