Feed Prebiotics-Inulin
BioVenic provides feed inulin prebiotic development services for the extraction, characterization, and efficacy evaluation of inulin as animal feed prebiotics, supporting feed prebiotic development, animal nutrition research, and finished product formulation. Our platform covers inulin extraction from chicory, Jerusalem artichoke, and other plant sources via process optimization (response surface methodology), structural characterization via HPLC, MALDI-MS, CE, NMR, SEM, DLS, and FT-IR/Raman, as well as in vitro (digestion, fermentation) and in vivo efficacy evaluation across livestock, poultry, and companion animals, alongside additive forms such as acylated inulin, nanoparticles, microcapsules, and synbiotics. We support inulin mechanism studies with digestive-tract and fecal microbiome, metabolome, and physiological-indicator analyses, and multi-omics (microbiome, metabolome, proteome) platforms to evaluate growth, immunity, disease resistance, and product quality.
Extraction and Characterization of Inulin Prebiotics
- Extraction of Inulin Prebiotics
We focus on the extraction and characterization of inulin prebiotics. Inulin is sourced from various plants such as globe artichoke, chicory roots, Jerusalem artichoke tubers, and elecampane. Using our advanced technology platform and techniques like response surface methodology, we optimize the extraction process to maximize yield and quality.

In Vitro Study of Inulin as Animal Feed Prebiotics
- In Vitro Prebiotic Efficacy of Prebiotic Inulin
In vitro studies play a vital role in evaluating the prebiotic efficacy of inulin as animal feed. By examining the effect of inulin on the growth and metabolites of probiotics through in vitro culture, such as Lactobacillus, we can assess the prebiotic effects and determine the appropriate dosage for promoting the growth of specific probiotics.
- In Vitro Digestion and Fermentation of Prebiotic Inulin
Our animal in vitro digestion and fermentation models help study the digestive and fermentation characteristics of inulin during gastrointestinal processes, providing insights into its bioaccessibility.
In Vivo Evaluation of Inulin in Animals
To evaluate the effectiveness of inulin in animals, in vivo experiments become necessary to assess its effects based on different types, dosages, and duration of administration. We offer various in vivo animal models as well as feed analysis, animal metabolite analysis, and omics study platforms. These resources enable researchers to evaluate the digestibility of inulin, its impact on growth, health, and other relevant indicators. Ultimately, these studies help determine the appropriate dosage and feeding methods for specific animals.
Some common assays used in in vivo animal studies of inulin are:
- Gut microbial flora: DGGE, 16S rRNA sequencing.
- Metabolites of gut microbial flora: short chain fatty acids (SCFAs), bile acids, etc.
- Microbial enzymes analysis.
Mechanism Study of Feed Prebiotics Inulin
Understanding the mechanism by which inulin regulates animal nutrition and health is crucial for effective supplementation in animal feed. Our research focuses on examining animal nutritional metabolites, physiological indicators, digestive tract and fecal microbiomes, and metabolomes. By synthesizing this information, we help elucidate the intrinsic mechanisms by which inulin enhances animal nutrition and health.
Feed Inulin Prebiotics Development
We offer one-stop solutions for the development of inulin products suitable for various animal feed applications.
Examples of Inulin feed additives:
- Acylated inulin: may be beneficial for delivering high concentrations of SCFA to more distal regions of the colon.
- Inulin nanoparticles: improve the bioavailability of multiple bioactive compounds
- Inulin microcapsules: may be a potential encapsulation matrix for essential oil.
- Inulin synbiotics: promote probiotic effects in animals.
Applications of Inulin as Feed Prebiotics
As a feed additive, inulin can affect the growth performance, immune function, disease resistance ability, product quality and other indicators of animals by regulating the growth of gastrointestinal microbiome. Some of the application effects of inulin in pigs, chickens, cattle, and companion animals are shown in Table. 2.

Development Workflow of Feed Prebiotics Inulin
Related Research
In a study investigating the effects of dietary inulin supplementation on gut microbiota modulation and neonatal health in a pregnant sow model, 40 sows were assigned to control or inulin-supplemented groups (10 g/day from gestation day 85 to farrowing) to evaluate maternal microbiota composition, colostrum quality, and neonatal piglet health outcomes. Results demonstrated that inulin supplementation significantly increased fecal Bifidobacterium and Lactobacillus abundances in sows during late gestation (p < 0.05), while reducing Escherichia coli and Clostridium perfringens populations. Colostrum analysis revealed that inulin-treated sows produced colostrum with significantly higher IgA and IgG concentrations, enhancing passive immune transfer to neonates. Neonatal piglets from inulin-supplemented sows showed significantly reduced diarrhea incidence (32% vs. 58% in controls) and lower mortality rates during the first 14 days of life. 16S rRNA sequencing of neonatal piglet fecal microbiota demonstrated that inulin supplementation accelerated the establishment of beneficial gut bacterial communities, with earlier colonization by Bifidobacterium and increased microbial diversity indices. Short-chain fatty acid (SCFA) analysis showed that inulin-supplemented neonates had significantly higher fecal acetate and butyrate concentrations, indicating enhanced microbial fermentation activity. This study establishes that maternal inulin supplementation during late gestation programs neonatal gut health through vertical microbiota transmission, colostral immune enhancement, and early SCFA-mediated intestinal maturation.

Case Study
Researchers conducted a dose-response fermentation study to characterize the prebiotic efficacy of inulin and optimize its application as an animal feed additive. Inulin sourced from chicory root was evaluated at four escalating doses alongside a no-additive control using an in vitro hindgut fermentation model simulating target animal gastrointestinal conditions. Short-chain fatty acid (SCFA) production profiles were analyzed as the primary readout of prebiotic activity. The stacked composition analysis revealed a clear dose-dependent response: total SCFA output increased 1.5-fold at low dose, reaching 3.5-fold with the optimized inulin formulation. Critically, the SCFA composition shifted favorably toward more beneficial metabolites—acetate proportion decreased from 60% (control) to 38% (optimized), while butyrate—the preferred energy source for colonocytes—more than doubled from 12% to 28%, and propionate increased from 20% to 30%. These findings demonstrated that optimized inulin supplementation not only amplifies total fermentative output but also selectively enriches for health-promoting SCFAs, supporting its development as a precision prebiotic additive for enhancing gut health, nutrient utilization, and immune modulation across multiple animal species.
