How to identify the age of small tailed Han sheep, and how much does an adult small tailed Han sheep

1.The teeth of young sheep are called deciduous teeth, which are white in color and smaller; The teeth of adult sheep are permanently toothed, yellowish in color, and larger. According to the age of tooth identification, the lower jaw of the sheep mainly looks at 4 pairs of incisors, the middle pair is called the incisor teeth, the two sides of the incisor teeth are the inner middle teeth, the outward is the outer middle teeth, and the outermost L pair is called the corner teeth.

2.At 1 year of age, the deciduous incisors are replaced with permanent incisors, and the middle teeth are removed within 2 years of age; 3-year-old lateral middle tooth replacement; 4-year-old corner tooth replacement; After the age of 5, it can be judged according to the size of the gap between the teeth, the degree of wear of the teeth and the condition of the teeth; Over 6 years of age, the gums are sunken, the teeth are oblique forward, and the crown of the tooth becomes narrow; 7 9-year-old tooth roots move and fall out one after another.

3.Experienced farmers and herdsmen in our country have identified the age of sheep in this way: "Changing teeth at the age of one, one pair of teeth at the age of two, two pairs of teeth at the age of three, three pairs of teeth at the age of four, and one tooth at the age of five, six flat, and seven obliquely."

The growth and development of small-tailed Han sheep is relatively fast, the newborn weight is in kilograms, about 6 kilograms at the full moon, and the fastest growth rate is 3-10 months old. At the age of 3 months, the average weight of weaned male and female lambs can reach 2 0 8 ±8 .

4 kg and 1 7 2 ±7 .0 kg; Fattening lambs can be fattened and slaughtered at the age of 4 months.

3 ±7 .8 kg; From 4 months to 12 months of age, the average daily weight gain of rams is about 150 grams; The ewes are about 89 grams. 3 During the 8-month period, the daily weight gain can reach about 240 g (216 266 g).

Adult rams are 9 4 1 ±2 3 .3 kg, ewes 4 8

Second, the identification of the authenticity of the small-tailed Han sheep.

1) The difference between 1 and a half year old lake sheep and small-tailed Han sheep and young sheep.

Hu sheep are native to the Taihu Lake area of Jiangsu Province and the Jiaxing area of Zhejiang Province. The lake sheep belongs to the lamb breed and is small. The market sheep sellers often use the similar characteristics of 1-and-a-half-year-old lake sheep and small-tailed Han sheep and young sheep to confuse the real with falsehood, but as long as you pay a little attention, the difference between the two types of sheep is still obvious.

The bred Hu sheep do not have horns, while the rams of the small-tailed Han sheep have horns, and the ewes have horns for the most part; The body of the lake sheep is oblate, the anterior chest is underdeveloped, the hindquarters are slightly higher, the growth and development are slow, the adult sheep is very small, the adult ram weighs 40 50 kg, and the adult ewe weighs 35 45 kg.

2) The difference between hybrid sheep and small-tailed Han sheep.

In some areas, the small-tailed Han sheep have been crossbred to produce a part of the hybrid sheep, although the body shape of these hybrid sheep is similar to the small-tailed Han sheep, but the physique is small, the growth rate is slow, the lambing rate is low, the benefit is poor, and the difference should be noted.

3. Excellent strains of small-tailed Han sheep.

The small-tailed Han sheep is an excellent local breed, which must be continuously purified and rejuvenated in production. After more than ten years of purification and directional breeding, the relevant domestic research institutes have formed a multi-tire high-yield line, and the production performance has been significantly improved. The weight of the ram is 35 50 kg at 4 months of age, and the weight of the ewe is 30 35 kg at 4 months.

Adult ewes give birth to 2 litters per year or 3 litters per 2 years, with 3 5 lambs per litter, up to 8 lambs. Adult rams are 100 cm tall, with a maximum body height of 110 cm, a weight of 125 kg, and a maximum weight of 180 kg; Adult ewes are 84 cm tall and weigh 80 kg, with a maximum body weight.

3. The difference between cross-bred hybrid sheep and authentic small-tailed Han sheep: some production areas have been hybridized and improved in the history of small-tailed Han sheep, and the growth rate of the offspring produced is slow, and the adult individuals are far inferior to the small-tailed Han sheep, and the lambing rate of ewes is low, and the economic benefits are poor.

With its large size, fast growth, good meat quality, high reproductive rate and strong adaptability, the small-tailed Han sheep has rapidly been popularized and bred throughout the country in recent years. As a result, the small-tailed Han sheep breeder soared. In order to make huge profits, some lawbreakers sell small-tailed Han sheep breeding sheep with fake and shoddy products.

The purebred small-tailed wool is pure white, the bridge of the nose is curved like an eagle's hook, the ewe's horns are sickle-shaped or ginger, and the ram has large, square spiral horns.
