Animal life comes from the environment, grows in the environment, and return to the environment, showing that animal health and environmental changes and development has been indissoluble.It turns out that both the natural environment, or social environment and its geographical environment will be different Which can cause the dynamic balance of the animal body to harm the animal health.At the same time, the environment has a certain impact on the occurrence, development and outcome of animal diseases.The paper reviews the impact of the natural environment, Animal Health social environment and the ecological environment on animal health.
Healthy animals are an important guarantee and prerequisite for conducting scientific experiments. Animal health status will directly affect the reliability and accuracy of the experimental results. In general, animal health is more tolerant to drugs and various stimuli than non-healthy animals, and the response is more stable. Animals with poor health or potential infections, such as poor health, Animal Health may deviate from the results of the experiment and even die during the course of the experiment. Therefore, in order to ensure the successful completion of the experiment to ensure the reliability and accuracy of the experimental results, we must use healthy animals to experiment. So, how to determine animal health? In general, animal health can be from the appearance and laboratory tests to determine the two major aspects: ① appearance (including): nutrition, mental status, reactivity, hair, mucosal color, breathing and so on. Healthy animals should be good nutrition, the spirit of no extravagant, lively, sensitive to the stimulus, hair smooth, good gloss, mucous membrane without cyanosis, breathing smooth. ② laboratory tests: healthy animals should be no disease, a variety of physiological and biochemical indicators of normal, Animal Health and should not carry experimental animal classification criteria outside the pathogens.
Identification of animal healthy mice
(A) the appearance of observation of mice should be physical development is good, normal shape, structural symmetry. The back is not arch, body muscle fullness, leg muscles strong, normal posture, movement fast and lively and powerful. Eyes bright and spirit, eyes sharp and agile, eye without secretions, eyelids without inflammation and swelling. Nose is not swelling, no secretions outflow. Whole body coat is complete, no lumps and trauma, Animal Health coat thick and shiny, milky white (whitening mice), close to the body and not chaotic fluffy. Breathe normal, do not make a sound.
Feet, tail does not swell or fester. Defecation normal, anal no dirt and so on.
(B) laboratory tests should be used to clean the above-mentioned mice, the mouse should be purchased from the provincial and municipal level issued by the experimental animal production permit breeding animal breeding units. First of all require not to carry animal infectious diseases and zoonotic pathogens; Animal Health also should not carry a large harm to animals and scientific experiments interfere with large pathogens.
Identification of animal health guinea pigs
(A) the appearance of observation guinea pigs should be well developed, the shape of normal, symmetrical structure, bones strong and strong, full and strong muscles, strong and strong, broad and straight back, abdomen tight, short limbs, parts symmetry, leg muscles, Agile and lively, strong exercise. Animal Health Eyes round and bright, no secretions. Coat thick and shiny, close to the body and not chaotic fluffy, no hair removal phenomenon. Nose moist, breathing normal. Feces normal, no dirt around the anus and so on.
(2) laboratory tests for the general level of guinea pigs should be excluded from the lymphocytic choriomeningitis virus, Salmonella, skin fungi, Toxoplasma gondii and in vitro parasites and other human and animal hazards and scientific experiments interfere with large pathogens The A variety of physiological and biochemical indicators normal.
