According to the World Health Organization, iron deficiency is the most common nutritional deficiency worldwide, a significant public health problem reflected in animal models. To study the physiological and biochemical impacts of this condition, researchers need to reliably and ethically induce iron deficiency in rats, a common animal model. This guide outlines standard methodologies for establishing this crucial animal model for research.

Scientific studies show that feeding rats a high-fat diet (HFD) can significantly increase body fat and visceral adiposity compared to controls, even with minimal initial weight gain. This phenomenon demonstrates how diet induced obesity in rats, providing crucial insights into the metabolic mechanisms driving weight gain and associated health issues in laboratory settings.

For decades, oral gavage has been a standard procedure in preclinical animal research, offering a way to precisely administer substances for study. To understand what oral gavage means for nutrition diet, it is vital to distinguish this controlled, often compulsory, research technique from its application in human medicine, where it serves as a critical method for providing nutritional support via tube-feeding.

According to research published by the National Institutes of Health, precise control of feeding variables is crucial for understanding metabolic disorders. This is where the technique of paired feeding comes into play, a rigorous research method used to ensure that any observed physiological differences between animal groups are due to the experimental variable and not simply a difference in caloric intake.
