The body length is between 15 and 20 cm, and the tail length is between 10 and 15 cm. The body length is longer than the tail length.  3, the main physiological data: body temperature 39 (38.5 ~ 39.5) ° C, heart rate 475 (370 ~ 580) times / min, respiratory rate 85.5 (66 ~ 114) times / min, tidal volume 0.86 (0.6 ~ 1.25) ml, contraction Pressure 84-134, diastolic pressure 60mmHg  4, temperament is more fierce, strong resistance to disease.  Guinea pig (Guinea-pig)  1, also known as guinea pig, sea pig, Dutch pig, Guinea pig.  2, late-generation animals, that is, the mother's pregnancy is longer, 63 (59-72) days, the embryo is fully developed in the mother's body, and has grown completely after birth.  3, the main physiological data: normal body temperature 38.6 (37.8 ~ 39.5) ° C, heart rate 280 (200 ~ 360) times / min, respiratory rate 90 (69 ~ 104) times / min, tidal volume 1.8 (1.0 ~ 3.9) ml, Blood pressure 75-120mmHg  4, herbivores, hi group. Habits are docile, timid and easy to surprise, like a dry and clean living environment.  Rabbit (Rabbit)  1, herbivorous monogastric animals. Like to live alone, less activities during the day.  2, normal body temperature 39.0 (38.5 ~ 39.50) ° C, skin temperature 33.5 ~ 36 ° C, heart rate 258 ± 2.8 times / min, arterial blood pressure 110 (95 ~ 130) mmHg, circulating blood volume 59 ± 2.3ml / Kg body weight, breathing Frequency 51 (38 ~ 60) times / min, tidal volume 21.0 (19.3 ~ 24.6) ml  3, the main varieties:  Chinese rabbit (also known as white rabbit, vegetable rabbit): the color of the coat is pure white, the weight is 3 to 5 kg, the environment is adaptable and the fertility is strong.  Cyanine rabbit (also known as goat green, gold base): each hair is divided into three colors. The tip of the ear and the tail and face are black, and the eye, tail and abdomen are white. The standard type generally weighs 5 to 7 kg, and the large body weight is 8 to 12 kg. The body is strong, adaptable and fast.  Big white rabbit (also known as big ear rabbit, Japanese big ear white): white color, red eyes, large size. The weight is 8-12 kg, the growth and development is fast, the fecundity is strong, but the disease resistance is poor.  Dog (Dog)  1, Mammalia, Carnivora, canine. Life expectancy is 10 to 20 years. The sense of smell is extremely developed, which is 1200 times that of human beings.  2, normal body temperature 39 (38.5 ~ 39.5) ° C, heart rate 80 ~ 120 beats / min, respiratory rate 18 (15 ~ 30) times / min, tidal volume 320 (251 ~ 432) ml, ventilation 5210 (3300 ~ 7400) Ml / min, oxygen consumption 580mm3 / g live weight, systolic blood pressure 149 (108 ~ 189) mmHg, diastolic blood pressure 100 (75 ~ 122) mmHg  3. Internationally used dogs for medical science research are: Beagle: native to the UK, the smaller of the hounds; Labrador dogs; fox-hunting hounds, Mexican hairless dogs, four Hybrid dogs, Boxer black and white spotted short-haired dogs, Greyhound dogs, etc.  Monkey (Monkeys)  1, macaques are most widely used in medical science research. The male monkey has a body length of about 55-62 cm, a tail length of about 22 to 24 cm, and a body weight of about 8 to 12 kg. The female monkey has a body length of about 40 to 47 cm, a tail length of about 18 to 22 cm, and a body weight of about 4 to 7 kg.  2. The normal body temperature of macaques is 38-39 °C during the day and 36-37 °C during the night. The heart rate is 168±32 beats/min, and the heart rate slows down with age. The systolic blood pressure was 120±26 mmHg, and the diastolic blood pressure was 84±12 mmHg. Respiratory rate 40 (31 ~ 52) times / min, tidal volume 21.0 (9.8 ~ 29.0) ml.  Cat (Cat)  1, normal body temperature 38.7 (38.0 ~ 39.5) ° C, heart rate 120 ~ 140 beats / min, respiratory rate 26 (20 ~ 30) times / min, tidal volume 12.4ml, systolic pressure 120 ~ 150mmHg, diastolic blood pressure 75 ~ 100mmHg.  2, cats are lonely, love bright and dry environment, adapt to the environment  |
