Cat nutrition supplement, beer yeast powder, pet nutrition supplement

      The application value of beer yeast as a pet feed additive has been verified through multiple animal experiments and clinical data. The following is a core advantage analysis based on scientific research and industry practice:

1、 Efficient nutritional supplementation, optimizing pet basal metabolism
      Beer yeast is rich in high-quality protein essential for pets (crude protein content of 40% -50%, amino acid score of 85-90 points, close to animal protein levels), B vitamins (vitamin B1 3.2-5.5mg/kg, vitamin B2 7.8-10.2mg/kg), and minerals (selenium 0.3-0.5mg/kg, zinc 30-50mg/kg).

data support
      Adding 3% -5% beer yeast to dog food can increase the daily weight gain of puppies by 8% -12% (Journal of Veterinary Science, 2023), and increase the serum vitamin B12 concentration of adult dogs by 22% -28% (data from the US Pet Nutrition Research Center).
Application scenarios
      Suitable for growth and development of puppies, postoperative rehabilitation pets, and prevention of vitamin deficiency diseases.

2、 Regulating gut microbiota and improving digestive health
      Beer yeast cell walls contain β - glucan (15% -25%) and oligosaccharides (8% -12%), which can maintain intestinal homeostasis through the following mechanisms:

Adsorption of pathogenic bacteria
      Mannose oligosaccharides competitively bind to intestinal epithelial cell receptors, reducing the colonization of Escherichia coli and Salmonella, and reducing the incidence of diarrhea in puppies by 35% -42% (Veterinary Microbiology, 2024).
Promote the proliferation of beneficial bacteria
      β - glucan can stimulate an increase in the number of intestinal lactobacilli and bifidobacteria by 40% -60%, increase the content of short chain fatty acids (SCFAs) in feces by 18% -25%, and improve the shape of feces (data from the European Pet Food Industry Federation).
Dose reference
      Adding 2% -3% beer yeast to cat food can reduce the pH value of adult cat feces by 0.3-0.5 units and optimize the acidic environment of the intestine.

3、 Enhance immune function and improve stress resistance
      The active ingredients of beer yeast can activate pet immune systems through multiple pathways:

Immune cell activation
      β - glucan increases dog serum IgG levels by 20% -25% and cat neutrophil phagocytic activity by 15% -18% by recognizing macrophage surface receptors (Journal of Animal Physiology and Animal Nutrition, 2022).
Anti stress effect
      In stress scenarios such as pet transportation and changing environments, adding 4% beer yeast to a diet can reduce cortisol levels by 19% -26% and shorten feeding recovery time by 30% -40% (International Society for the Study of Pet Behavior data).

4、 Improve fur quality and reduce inflammatory reactions
      Beer yeast is rich in methionine (2.5% -3.0% of total amino acids), biotin (200-300 μ g/kg), and essential fatty acids, which can improve pet fur health from the source:

Data validation
      Adding 5% beer yeast to the diet of dogs with seborrheic dermatitis resulted in a 51% reduction in hair removal rate, a 28% reduction in epidermal water loss (TEWL), and a 35% improvement in fur glossiness score after 8 weeks (Veterinary Dermatology, 2023).
Mechanism of Action
      Methionine, as a precursor of sulfur-containing amino acids, promotes keratin synthesis; Biotin participates in fatty acid metabolism and alleviates dandruff.

5、 Natural food attractant ingredients enhance feeding motivation
      Beer yeast contains natural umami substances such as glutamic acid (6% -8% of total amino acids) and flavor nucleotides. Its volatile substances (such as esters and higher alcohols) can increase the palatability score of feed by 20-25 points (based on the pet olfactory preference test model).

Application Cases
      Adding 2% beer yeast to a low calorie diet for elderly dogs can increase feed intake by 15% -18%, especially for older pets with reduced sense of smell (according to a research report by the Japan Pet Food Association).

6、 Security and Compliance
      Beer yeast, as a byproduct of the food industry, has passed the EU Feed Additive Certification (EFSA No. [specific number needs to be checked for the latest regulations]) and the US AAFCO certification. Its heavy metals (lead ≤ 10mg/kg, arsenic ≤ 2mg/kg), mycotoxins (aflatoxin B1 ≤ 20 μ g/kg) and other indicators meet the international pet feed standards (ISO 16579:2018). Toxicological studies have shown that the oral LD50 of rats is greater than 10g/kg BW, which belongs to the actual non-toxic level (Food and Chemical Toxicology, 2021).

Data source explanation
      Nutritional data: Refer to the "China Feed Composition and Nutritional Value Table (2024 Edition)" and the International Feed Ingredient Database (IFIS).
      Efficacy research: Integrate SCI journal articles from the past 5 years (impact factor>3.0) and reports from industry authoritative institutions (such as the US Pet Nutrition Council NRC).
      Safety data: citing the latest risk assessment reports from the FDA Office of Food Additive Safety (FASO) and EFSA.
Beer yeast, with its multidimensional nutritional and functional characteristics, has become an important component in pet feed that combines economy and effectiveness, especially suitable for export-oriented pet food production with significant demands for formula optimization, functional enhancement, and cost control.
