What should be paid attention to in the introduction of farmed mutton sheep

In order to be introduced from qualified farms in strict accordance with the provisions of relevant laws and regulations, and from non-epidemic areas, the introduced breeding sheep farms must have livestock and poultry production and operation licenses and animal epidemic prevention certificates, and imported breeding sheep must have quarantine certificates and pedigree files.

When the sheep were one and a half years old, the deciduous teeth were replaced by permanent incisors, the middle teeth were replaced at 2.5 years old, the middle teeth were replaced at 3 years old, and the corner teeth were replaced at 4 years old. After 5 years old, according to the size of the gap between teeth, the wear degree of teeth and the condition of teeth, the gums were sunken over 6 years old, the teeth were oblique forward, the crowns became narrower, and the roots moved and fell off one after another at the age of 7 to 9 years old.

Healthy sheep are lively and active, with bright eyes, shiny hair, exuberant appetite, normal breathing and body temperature, strong and powerful limbs, while diseased sheep have scattered hair, rough and no light, big eyes, standing still, anorexia, shortness of breath, elevated body temperature, body surface and limbs are sick and so on.
