What are the advantages of small-tailed Han sheep?

Small-tailed Han sheep is a sheep breed used both for meat and fur in China, which has the characteristics of rapid growth, early maturity, strong fecundity, genetic stability of performance, strong adaptability and so on. It has been designated as a famous breed by the state, and has been praised as China's "national treasure", the world's "super sheep" and "high-legged sheep", and has been listed in the "National Animal and Poultry genetic Resources Protection Catalog". Let's take a look at the advantages of small-tailed Han sheep.

Fast growth rate

The small-tailed Han sheep can be fattened at the age of 4 months, the annual fattening rate is more than 400%, the body weight can reach 50 kg at the age of 6 months, 100 kg at the age of one year, and 130 kg to 190 kg for adults. The slaughtering rate of one-year-old fattening sheep is 55%, and the net meat rate is 45.89%. The meat is tender, the intermuscular fat is marbled, fat and thin is moderate, delicious and juicy, fat but not greasy, fresh but not thick.

Strong adaptability

Although small-tailed Han sheep are Mongolian sheep, they have developed the habit of "house-feeding and captivity" for thousands of years in southwestern Shandong, so the natural conditions such as sun, rain and cold can be adjusted by enclosures and are rarely affected by regional climatic factors. can grow, develop and reproduce normally all over the country.

Hereditary stability

The genetic performance of small-tailed Han sheep is stable, the high-yield offspring can well inherit the production potential of their parents, and the breed characteristics remain obvious, especially the multi-lambing and prolific characteristics of small-tailed Han sheep can be stably inherited.

Fur is of good quality.

The lambskin of 1 ~ 6 months old small tail Han sheep is a good product to keep out the cold in winter, with many curved flowers and beautiful spikes. After the lambskin of 4 ~ 6 months old is processed and cooked, the plate is thin, light in weight, tough in texture, white as jade in color, soft in luster, tight in flower bending and kink, clear and beautiful in flower design, and its fur-making value is comparable to that of the famous Tan sheep fur in China, but the skin area is much larger than that of Tan sheep's fur. Adult sheepskin has a large area and tough texture, so it is suitable for leather making.

Sexual maturity is earlier.

The male sheep of small tail Han sheep matured at the age of 5 months, 85% mature sperm were found in the vas deferens, 100% mature sperm could be seen at the age of 6 months, and the sperm density in the original semen was 3 billion / ml, which basically reached the standard of insemination. A small amount of mating can be used in 8-month-old rams, but it is necessary to strengthen breeding. Under the premise that the nutritional needs of 1-year-old rams are met, it is best for them to participate in mating.

Strong fecundity

Small-tailed Han sheep can breed all the year round, giving birth in two years, and many of them give birth twice a year. According to the statistics of 2101 births from 1964 to 1991, the small-tailed Han sheep is a prolific breed, with an average lambing rate of 281.9% and a maximum of 9 lambs per litter. Its reproductive performance has two remarkable characteristics: one is that within the first four births, the lambing rate increases greatly with the increase of parity. Second, the third and fourth lamb rate of the third and fourth parity is about twice that of the first and second parity, accounting for more than 40% of the number of ewes delivered.
