Teach you the method of distinguishing the true and false of small-tailed Han sheep

I. the difference between crossbred "hybrid sheep" and authentic small tail Han sheep

In the history of some producing areas, the small-tailed Han sheep have been crossbred and improved, and the growth rate of the offspring 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 benefit is poor.

2. the difference between inbred "degenerate sheep" and optimized "high-legged" small-tailed Han sheep.

Some sheep farmers' long-term inbreeding caused breed degradation, although there was no significant difference in appearance between small-tailed Han sheep and small-tailed Han sheep, they developed slowly, had small size, shorter legs and less lambs, while the preferred small-tailed Han sheep grew fast, had large individuals, gave birth to more lambs and had good meat quality.

Third, the difference between one-and-a-half-year-old "Hu Yang" and small-tailed Han sheep.

The bred Hu sheep have no horns, but most of the small-tailed Han sheep have horns, the body of the Hu sheep is flat and long, the forequarters are underdeveloped, the hindquarters are slightly taller, the growth and development is slow, and the adults are small, which is significantly different from the small-tailed Han sheep.

4. The difference between artificial "tooth-removed sheep" and normal "tooth-changing sheep".

Some lawbreakers pulled out the middle two incisors of the old small-tailed Han sheep that had lost their production capacity, and then falsely claimed that they were young sheep who had just changed their teeth, pretending to be old and deceiving buyers. To identify this phenomenon, it must be clear: the deciduous teeth of lambs and young sheep are white, while the permanent teeth are yellow and large; the longer and heavier the permanent teeth are worn, and the shorter the teeth are, the older the sheep is, that is, the "old-fashioned" sheep or the "old sheep" with artificial tooth removal. Do not buy it.

5. The difference between Shaanxi "Tong Sheep" and small tail Han Sheep.

The figure and appearance of Shaanxi "Tongyang" is similar to that of small-tailed Han sheep, but its limbs are slightly shorter, the ram tail is large, and the rams and ewes have no horns, while the legs of the small-tailed Han sheep are high, and only very few ewes are hornless.

6. the difference between Xinjiang "Hetian Sheep" with similar appearance and small tail Han Sheep.

Hetian ewes are mostly hornless, and due to poor opening of ribs, narrow chest, small adult sheep body and mixed hair color, especially with irregular black spots on the head, less than 20% of the ewes are completely white; while the ewes with small tail Han sheep have very few horns, and the chest is open, the adult sheep is tall and large, and the wool color is pure white.
