Animal Plastinated Specimens – Facilitating Efficient Absorption of Animal Husbandry Knowledge

 Animal plastination is the preservation of animal carcasses using special plastination techniques. This process allows them to retain their original shape, color, and structural details over long-term preservation, creating permanent exhibition and research materials. Compared to traditional specimen preservation methods, plastinated specimens can present the animal's anatomical structure in greater detail, even showcasing the details of internal organs and tissues without cutting them. In animal husbandry education, animal plastinated specimens play an important role, specifically in the following aspects:

Providing realistic and intuitive teaching materials

Animal plastinated specimens can clearly demonstrate the internal structure of the animal body. For example, when explaining the digestive system of cattle, plastinated specimens allow students to visually see the shape, size, location, and connections between the rumen, reticulum, omasum, and abomasum. This intuitive display is more three-dimensional and realistic than simple book pictures or two-dimensional animations, helping students accurately understand the spatial relationships of organs.

For the skeletal structure of animals, plastinated specimens can completely present the morphology of the skeleton, including the structure of the joints. Students can touch and observe skeletal specimens, learning about the shapes and textures of different bones and their interactions during movement. This is crucial for understanding the principles of animal mechanics.

When studying the circulatory system, plastinated specimens, through special staining techniques, clearly display the vascular network. Students can observe the distribution and course of arteries and veins, as well as the connection between the heart and blood vessels. This visual presentation helps students understand the circulatory pathways and material exchange processes within the body.

For the reproductive system, plastinated specimens can demonstrate the detailed structure of male and female reproductive organs. For example, when explaining the reproductive system of sows, students can see the morphology and positional relationships of organs such as the ovaries, oviducts, and uterus, understanding the reproductive physiology of animals, including fertilization and embryonic development.

In animal husbandry courses, learning about animal diseases, pathology, and treatment methods is an important component. Plastinated specimens preserve actual samples of animal pathologies, helping students visually understand the effects of different diseases (such as intestinal diseases, respiratory diseases, and parasitic infections) on animal tissues and organs, enhancing their understanding of pathology.

Plastinated animal specimens facilitate practical teaching.

Compared to traditional fresh specimens, plastinated specimens offer superior durability. They do not easily rot or deteriorate, and require no complex preservation conditions such as refrigeration or chemical preservatives. In animal husbandry education, teachers can use these specimens for extended periods, readily available for both annual freshman orientations and repetitive explanations of different course content.

For example, in anatomy courses, students can observe plastinated specimens from multiple angles to learn about different structures of the same specimen without worrying about damage or loss of teaching value. This greatly helps students master anatomical skills.

Fresh animal specimens may carry various pathogens, posing certain biosafety risks during dissection. Plastinated specimens, having undergone processing, eliminate pathogens, providing a safe teaching environment for teachers and students. Students do not need to take cumbersome protective measures, such as special gloves and masks, allowing them to focus more on learning anatomical skills and observing specimen structures.

Promoting Interactive Learning and Self-Directed Learning

Animal plastinated specimens, with their lifelike appearance and realistic texture, can attract students' attention. When students see exquisite plastinated specimens, they are more likely to develop curiosity and a desire to explore. For example, when a plastinated horse specimen is displayed, students may become interested in the horse's muscle lines and body proportions, thus actively asking questions, which helps create a positive learning atmosphere.

In classroom teaching, teachers can divide students into groups to discuss and learn about plastinated specimens. Students can share their observations of structural features, raise their questions, and explore answers together. This group cooperative learning method can cultivate students' teamwork spirit and self-directed learning ability. For example, when studying the animal respiratory system, student groups can observe the structure of the trachea, bronchi, and lungs in the plastinated specimen and discuss the process and mechanism of gas exchange.

Animal plastinated specimens play multiple roles in animal husbandry education. They serve as an auxiliary tool for basic knowledge such as anatomy and physiology, help students better understand advanced topics such as animal diseases, reproduction, and genetics, and also promote the development of practical skills. With the development of animal husbandry education, plastinated animal specimens will undoubtedly play an increasingly important role in cultivating more professional and comprehensive animal husbandry talents and promoting the sustainable development of animal husbandry.
