Abstract

Veterinary anatomy education faces several challenges, including increasing student enrollment, regulatory restrictions on animal use, and limitations of traditional preservation methods. Formalin preservation poses health risks, while plastination is costly and lacks flexibility. The conventional and modified Elnady Techniques present a safer and more cost-effective alternative, offering soft and flexible specimens; however, the adverse features still appear, and some steps require expensive equipment. This study aims to refine these Elnady Techniques, called ‘innovative glycerin impregnation’ for preserving female reproductive organs by reducing costs and simplifying the process using basic equipment. Additionally, veterinary students' satisfaction with glycerin-preserved specimens was compared to that with plastinated specimens. Results showed that glycerin-preserved livestock genital tracts demonstrated superior characteristics, including softness, flexibility, endurance, and neutral odor. Fixation and dehydration at 4°C contributed to well-preserved specimens suitable for anatomical education. Veterinary students significantly (P < 0.05) preferred glycerin-preserved specimens over plastinated specimens for realism, clarity of anatomical details, softness, flexibility, artificial insemination (AI) training, and more effective for prosection-based learning in veterinary anatomy courses. In conclusion, glycerin impregnation proves to be a reliable preservation technique for high-quality anatomical specimens, meeting educational standards while being practical, cost-efficient, and environmentally friendly. This method can be easily implemented in general laboratories using simple equipment and chemicals, making it an accessible option for preserving animal specimens.
