Area of Science:

  • Biomedical Research
  • Animal Models

Background:

  • Rodents are common, but pigs offer unique advantages for specific research areas.
  • Pigs share anatomical, nutritional, and physiological similarities with humans.

Purpose of the Study:

  • To highlight the suitability of pigs as biomedical models, particularly for obesity, diabetes, and cardiovascular research.
  • To discuss the role of gastrointestinal microbiota in obesity using pig models.

Main Methods:

  • Review of existing literature on pig models in biomedical research.
  • Focus on characteristics relevant to obesity, diabetes, and cardiovascular studies.
  • Discussion of dietary induction of obesity and gastrointestinal microbiota sampling.

Main Results:

  • Pigs serve as excellent models for obesity, diabetes, and cardiovascular research due to their human-like physiology.
  • High-fat diets are effective in creating experimental obesity models in pigs.
  • Obesity is associated with shifts in gastrointestinal microbiota, though specific causes remain elusive.

Conclusions:

  • Pigs are a highly relevant animal model for human disease research, especially metabolic and cardiovascular conditions.
  • Further research is needed to elucidate the causal role of gut microbiota in obesity.
  • Standardization of microbiota sampling sites is crucial for reliable results.
