Young sheep's teeth called milk teeth, white and small color; adult sheep teeth permanent teeth, yellow color, larger. To identify the age of the teeth, the main look of the sheep's jaw has 4 pairs of incisors, the middle pair is called the incisor, the internal teeth are on both sides of the incisors, the outward and outward teeth are the outward teeth, and the outermost l are called the molars.
At the age of 1.5, the milk cutting teeth are replaced by permanent cutting teeth, and the middle teeth are removed within 2 to 2.5 years of age; the middle teeth are replaced at the age of 3 years; the teeth are removed at the age of 4 years; after the age of 5, the size of the gap between teeth and the teeth are The degree of wear and the condition of the teeth are used to determine; gingival depressions older than 6 years old, teeth sloping to the front, and the crown of the teeth becoming narrow; 7 to 9 years old tooth root activity gradually falls off.
Our experienced peasants and herdsmen identify the sheep’s age as follows: “One year old will change his teeth, two years old will have one pair of teeth, three years old will have two pairs of teeth, and four years old will have three pairs of teeth. Five qi, six ping and seven will lean out one tooth.†This method is easy to remember and easy to grasp and promote. There are certain rules in the occurrence, removal, and wear of sheep teeth. The use of these laws can infer the age of the sheep.
