How to tell the age of the small tailed Han sheep ram

This depends on the lower teeth of the small-tailed Han sheep, 2 big teeth are one year old, 4 big teeth are 2 years old, and so on, I hope it will be helpful to breeding friends.

There are two ways to determine the age of a sheep:

1. Judge according to your teeth.

There are certain rules for the occurrence, replacement and wear of sheep teeth, and the age of sheep can be inferred by using these laws.

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.

At the age of age, the deciduous incisors are replaced with permanent incisors, and the middle teeth are removed within 2 2 5 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.

Second, according to the corner wheel judgment.

Each horn wheel is one year old, and the age of the goat can be known according to the number of horn wheels. However, it is mainly judged by teeth. That is, from the root of the horn along the tip of the horn upwards to count the number of "ridges" on the horns, if there is 1 edge, plus 1 concave at the root, it is 2 years old, 2 edges are 3 years old, 3 edges are 4 years old, and so on.

It can be identified by the sheep's teeth. There is a certain regularity in the occurrence, replacement, and wear of sheep teeth, which can be used to estimate the age of sheep.

The teeth of the young lamb are called mastodons, which are white and small in color; The teeth of adult sheep are permanent, yellow, and large in color. Depending on the age of the teeth, sheep have four pairs of incisors in their lower jaws. The middle pair is called the front teeth.

The incisors are flanked by the inner and outer middle teeth, and the outermost L pair is called the corner tooth.

At age the first incisor is replaced by a permanent front tooth and the middle tooth is replaced between the years; Intermediate teeth are replaced over 3 years of age; Angular teeth are replaced at age 4; After 5 years of age, the size of the tooth gap, as well as the degree of the tooth and the condition of the tooth can be judged; The gums are sunken over 6 years of age, the teeth protrude obliquely forward, and the crown narrows; 7 9-year-old tooth roots move and fall out one after another.

Sheep is a general term for the sheep subfamily, mammals, artiodactyls, bovidae, sheep subfamily, and is one of the domestic animals of humans. Hairy four-legged ruminants are the main ** of wool. The coat color is predominantly white. Goats and sheep are mainly raised in our country.

Sheep are also known as sheep or white sheep. Hairy four-legged ruminants. It was originally a product of the mountains of the northern hemisphere and was related to goats; The difference is that the body is fatter, the body is plump, and the body hair is dense.

Short head. Males have large, spiral-shaped horns, while females have no horns or only tiny horns.

There is a way to determine the age of rabbits, weasels and other animals by examining them under a microscope.

In this method, the mandibles of hares and other animals are cut, ground into thin slices, stained, and observed under a microscope to see the layers of the bones, and the age of the animals can be accurately inferred based on the number of bone layers. Because the animals are all younger, it is quite effective to use this method. If it is a large animal like a whale, its age can be known by taking its teeth and examining them under a microscope.

Three tricks to teach you to see the age of the sheep, listen to what the guy said, does it make sense.

The age of the sheep can be determined by changing their teeth. Generally speaking, 1 year old does not prick teeth (does not change teeth), 2 years old L pair of teeth (incisors erupt), 3 years old two pairs of teeth (inner middle teeth erupt), 4 years old 3 pairs of teeth (outer middle teeth erupt), 5 years old full mouth (corner teeth erupt), 6 years old flat (the upper part of the tooth is flattened from the tip), 7 years old oblique (the gums are sunken, some teeth begin to move), 8 years old crooked (there is a large gap between the teeth), 9 years old (teeth fall out).

It is most noticeable at the age of two, with only two lower teeth, and two per year thereafter. Four teeth at three years and six teeth at four years. Eight in total.

The sheep is old, and then a gap appears between the two teeth in the middle, which the herders call "slicing". At this time, the sheep will have to deal with it, because the physique is getting worse and worse, and they are starting to lose their teeth.

1. The difference between Xinjiang Hetian sheep and small-tailed Han sheep with similar appearance: Hetian sheep ewes have no horns, and due to poor rib opening, narrow chest, adult sheep body is small, and the coat color is mixed, especially the head has irregular black spots, and the coat is less than 20; There are very few small-tailed Han sheep ewes without horns, and the chest is open, the adult sheep is tall and large, and the coat color is pure white without impurities.

2. The difference between the similar Shaanxi sheep and the small-tailed Han sheep: the body shape and appearance of the Shaanxi sheep are similar to the small-tailed Han sheep, but the length of its limbs is slightly shorter, the ram tail is large, and the male and female sheep have no horns, while the small-tailed Han sheep legs are high, and only very few ewes have no horns.

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.

The small-tailed Han sheep is an excellent sheep breed in China, which originates in southwest Shandong Province, and has the characteristics of high reproduction rate, early maturity, fast growth, tall physique, high meat production performance, stable genetic performance and strong adaptability. At present, it has been introduced in large quantities in the western region. However, there are a considerable number of farmers in other places who do not understand what small-tailed Han sheep is, and there is a phenomenon of blind rush to buy.

Because the goods bought were fake, the expected level of production and economic benefits were not produced. Here, the author would like to remind farmers in the new breeding area to pay attention to identification. 1. Breed characteristics of small-tailed Han sheep Purebred small-tailed Han sheep have a large body, long body, high limbs, and a raised nose bridge, flat and drooping.

Rams have large spiral horns; Ewes have small horns, ginger horns, horn buds, and horn roots, and very few have no horns. The ram has a large head and a thick neck, the ewe has a small head and a thin neck, the fat tail is above the flying joints, and the body coat is white. 2. Identification of the authenticity of small-tailed Han sheep 1. The difference between one-and-a-half-year-old lake sheep and small-tailed Han sheep and young sheep.

Generally, the vast majority of fake small-tailed Han sheep sold are impersonated by lake sheep. Hu sheep are native to the Taihu Lake area of Jiangsu Province and the Jiaxing area of Zhejiang Province. Hu sheep belong to the lamb breed, the individual is small, slaughtered within 3 days after birth, and its skin is used to process fabrics.

The market sheep sellers often take advantage of the similarity between one-and-a-half-year-old lake sheep and small-tailed Han sheep and young sheep to confuse the real with the fake. But with a little attention, the difference between the two types of sheep is 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 flattened and elongated, 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 is only 40 50 kg, and the adult ewe is only 35 45 kg. 2. The difference between hybrid sheep and small-tailed Han sheep. Some areas have carried out crossbreeding on small-tailed Han sheep, produced a part of hybrid sheep, although these hybrid sheep are similar in body shape to small-tailed Han sheep, but the physique is small, the growth rate is slow, the lambing rate is low, the benefit is poor, and it is necessary to pay attention to the difference.

3. Excellent strains of small-tailed Han sheep The small-tailed Han sheep is an excellent local breed, and it must also 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 ram is 35 50 kg at 4 months of age, and the ewe is 30 35 kg at 4 months.

2 litters in 1 year or 3 litters in 2 years, 3 5 lambs per litter, up to 7 8 lambs. Adult rams are 100 cm tall and have a maximum body height of 110 cm. weight 125 kg, maximum weight 180 kg; Adult ewes are 84 cm tall and weigh 80 kg, with a maximum weight of 125 kg.

With the rapid development of animal husbandry after China's accession to the WTO, especially the peasants, farm workers have really tasted the sweetness of sheep raising. In the craze of workers buying small-tailed Han sheep, the sheep sellers in the market took advantage of the urgency of the masses to buy small-tailed Han sheep and began to sell fake small-tailed Han sheep. To this end, the identification of real and false small-tailed Han sheep is now introduced to farmers to avoid being deceived.

1. Characteristics of small-tailed Han sheep: small-tailed Han sheep is an excellent local breed. It is a high-quality line with multiple fetals, good production performance, two litters a year or 3 litters in 2 years, 3 5 lambs per litter, up to 7 to 8, adult rams are 100 cm high, the maximum body height is 110 cm, the weight is 125 kg, the maximum weight is 180 kg, the adult ewe is 84 cm high, the weight is 80 kg, and the maximum weight is 125 kg.

Raising small-tailed Han sheep is a highly profitable breeding industry. 2. Characteristics of small-tailed Han sheep: purebred small hairy Han sheep have a large body shape and a long body; The ram is 35-50 kg old at 4 months, with high legs, a raised nose bridge, and a large and droopy body.

The ram has large spiral horns, the ewe has small horns, ginger horn buds and horn roots, rarely hornless, the ram has a large head and a thick neck, the ewe has a small head and a thin neck, and the fat tail is above the flying joint, which is semicircular. 3. Identification with Shandong Hu sheep: There is a kind of lake sheep in Shandong, which is similar to the young sheep of the small-tailed Han sheep of more than 1 year old in appearance about 1 and a half years old, so the sheep dealers take advantage of the weakness of some people's poor identification ability, and they use the fake small-tailed Han sheep to pretend to be the small-tailed Han sheep with the lake sheep.

Use this to cheat money. If you look closely, there is a difference between this lake sheep and the small-tailed Han sheep. Breeding lake sheep do not have calf horns, and the body drive is elongated, the predrome is not developed, the posterior drive is high, the growth rate is very slow, the adult sheep is small, the adult ram is 38 48 kg, the adult ewe is 32 42 kg, the legs are not high, and the bridge of the nose is not raised.

4. Identification with other hybrid sheep: In recent years, some areas have crossbred small-tailed Han sheep to produce hybrid sheep. Although this part of the hybrid sheep is somewhat similar in appearance to the small-tailed Han sheep, it is completely different in substance.

The tail of the small-tailed Han sheep is fat tail and is round in patches, whereas the tail of the hybrid sheep is long and the legs are not high. The main thing is that hybrid sheep have a slow growth rate, a low lambing rate and, of course, poor benefits.

The small-tailed Han sheep has the following characteristics, which can be identified according to its characteristics:

1. Body and weight The small-tailed Han sheep has high limbs, developed forequarters and hindquarters, a straight waist and back, and a long head and neck.

2. The tail of the small tail is small, the tail fat is short, the tail shape of the ram is round and fan-shaped, the tip of the tail is turned up and buckled, and the tail length does not exceed the flying joint. There is a shallow groove in the middle of the outer tail, the tip of the tail is reversed upward, and the dry tail groove is pasted, generally 18 cm in length and width; The tail shape of the ewe is very inconsistent, mostly oblong, the tail is 14 cm long, the longest is only 23 cm, the width is cm, some of the tail roots are wider and gradually narrower downward, triangular, and some have the tip of the tail turned upward.

3. The head of the small-tailed Han sheep head has a slightly raised nose bridge, and the ears rotate flexibly, generally drooping downward. Rams have spiral-shaped large horns, their horns are solid, the tips of the horns are slightly outward, and some are inward, which is called "piercing the gills". The angles are triangular; The ewe has a small head and a long neck, and has no horns or small horns.

About half of the ewes have horns, but most of them only have horn roots, sickle-shaped horns, antlers and short horns.

4. Coat-color Small-tailed Han sheep is the most self-colored hair, accounting for more than 70% of the total, followed by black spots or brown spots on the head and limbs, and the black or brown head is mostly concentrated around the eyes, the tips of the ears, the cheeks or the mouth. The small-tailed Han sheep has a small coat density, no down on the abdomen, less hair on the upper ends of the limbs, and less oil sweat than the fine-haired sheep. The coat can be divided into three types: fur type, fine hair type and coarse hair type, and the fur type has clear hair strands and obvious curvature. Fine hair type with fine capillaries and small bends; Coarse hairs are coarse and curved large.

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.

Six-month-old rams are 40 kg, ewes are about 35 kg, and year-old rams weigh 6 0 8 ±1 4 .6 kg, ewes 4 1

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

7 ±1 0 .8 kg;

Small-tailed Han sheep adult ram about 150 kg Ewe about 80 kg, we are a large small-tailed Han sheep professional breeding farm, sincerely make friends who love breeding, communicate with each other.
