The Small Tail Han sheep is a highly productive breed, known for its excellent reproductive performance, superior meat quality, and valuable leather characteristics.
In terms of reproduction, these sheep reach sexual maturity early. Ewes typically begin breeding at 6–7 months, while rams are ready at 10–12 months. The estrus cycle of ewes lasts about 17 days, with a gestation period of around 149 days. After giving birth, ewes usually come into heat again within 1–3 months, resulting in a short reproductive cycle of 6–8 months. This allows for two or even three lambings per year. On average, each ewe gives birth to 2–4 lambs, with some cases reaching up to 7. The lambing rate increases with the number of births, and the overall average lambing rate of the breed reaches 270%, which is significantly higher than that of other sheep breeds both domestically and internationally.
Regarding meat production, the Small Tail Han sheep exhibits fast growth and early maturation. Lambs grow quickly and are ideal for early slaughter. Under good management conditions, a male lamb at three months old can weigh 26 kg, with a carcass weight of 13.6 kg and a net meat weight of 10.4 kg. Female lambs of the same age weigh around 24 kg, with a carcass of 12.5 kg and 9.6 kg of net meat. By six months, rams can reach up to 46 kg, with a carcass of 23.6 kg and 18.4 kg of usable meat. Ewes at six months may weigh up to 42 kg, with a carcass of 21.9 kg and 16.8 kg of meat. The dressing percentage is around 55.6%, and the net meat rate is approximately 45.89%. The meat is tender, marbled with intermuscular fat, and has a balanced fat content. It is juicy, not greasy, and has a fresh, non-gamey flavor. Rich in protein, low in cholesterol, and high in essential amino acids, vitamins, and minerals, it is an ideal food for the elderly, children, and those in need of nourishment.
In terms of leather quality, the skin of Small Tail Han lambs is highly valued. At 4 months old, their hides are thin, light, and have a soft texture with white hair resembling jade. They are easy to process and produce beautiful patterns, making them suitable for high-end winter garments. Adult skins are large in size and tough in texture, ideal for leather production. An adult male's hide can cover up to 12,240–13,493 square centimeters, equivalent to 2.48 standard skins. This makes the leather highly valuable for use in clothing, handbags, and industrial leather products.
