1, experimental animal genetics is a science that uses the principle of gene regulation to control the genetic characteristics of animals, cultivate new experimental animal varieties, strains and various animal models, and achieve the goal of experimental animalization.
2. Laboratory microbiology and parasitology is a science that studies the classification and biological characteristics of microorganisms and parasites in experimental animals and their relationship with humans and animals.
3. Mainly study the influence of physical and chemical factors (temperature, humidity, airflow, wind speed, air pressure, ammonia, harmful gases, etc.). ), nutritional factors (feed, water, etc. ), living environment (house, cage, bedding, eating and drinking utensils, etc. ) and biological factors (individual relationship, feeding density, microorganisms, parasites, other animals and humans, etc. ) on experimental animals.
Extended data:
Research methods: There are many kinds of animals, which are extremely complicated as a discipline, but to sum up, their research methods are nothing more than:
1. Description: Through observation, truthfully record the appearance, internal structure, living habits, economic and academic significance of animals with words and graphics.
2. Comparative method: through systematic comparison between animals, we can infer similarities and differences, understand their internal relations and draw laws.
3. Experimental method: Under artificial conditions, observe the phenomena of animal life and life activities by physical, chemical and biological methods, and reveal the essence of animal life and life activities. Experimental methods are often carried out at the same time as comparative methods.
