(1) Check the genealogy in detail and look at the features.
The superior species should have a complete pedigree file. Pedigree should record the number of ears, origin, date of birth, coat color characteristics, weight, growth and reproductive performance of 3 ~ 5 generations. The purchased breeding rabbits should be descendants of fine ancestors and have obvious characteristics of this breed. Breeding male rabbits should come from different lineages (the relationship coefficient between breeding male rabbits is smaller), the age is 2-4 months, and the weight is1.25-2.5 kg. The mortality rate of rabbits below 1 kg is high. According to the teeth, claws, weight to verify the age of the month, in case the rabbit is older.
(2) Check the first seven holes and the last two holes.
Healthy rabbits have bright eyes, rosy eyelids, clean eyes and no secretions. Clean nose, normal breathing, no runny nose, no sneezing. The color of oral mucosa is normal, and there are no ulcers, rotten spots and abnormal teeth. Ears upright, flexible rotation. The auricular points are clean, with no scab and dirt. The anus is clean and there is no sticky feces. There is no trace of brown feces around the coat. Tap the vulva to distinguish between men and women. The vulva is clean without edema, ulcer, scab and purulent secretion.
(3) Look at the abdomen at close range and move it at a long distance.
Check that the number of abdominal nipples should be more than 8, and those less than 8 should not be planted. Male rabbit testicles are symmetrical and elastic. The scrotum is clean and ruddy, without edema and ulcer. It is necessary for adult rabbits to prevent monogamy or cryptorchidism. Stand at 2 ~ 3 meters to check the posture and walking of the rabbit. Lift the rabbit 30 cm from the ground to see if it is stable when looking at the ground. It is necessary to prevent "O"-shaped legs, "splayed" legs, waist folding and hind limb paralysis.
(4) Touch a line and check the four fulcrums.
A line, that is, the spine, should be straight without protrusions or depressions. The back muscles are plump, the spine is not exposed, the back is curved from the back, and the hindquarters are plump and developed. If the spine is abacus-shaped and triangular in shape, it is a thin rabbit, which may be malnutrition or parasitic disease. Four-legged hair should be thick, bright skin, no ringworm and abscess. The claws of young rabbits should be hidden in the hair of the feet, short and straight, and the red line of the claw center is longer than the dry tip.
