Dorper sheep

Dorper sheep, originally from South Africa, are among the most renowned meat breeds globally. Known for their outstanding genetic traits and high breeding value, they have become a preferred choice for farmers worldwide. **Physical Characteristics** Dorper sheep have a robust and well-proportioned body, with a long, broad, and deep frame that resembles a barrel shape. Their bones are short and compact, giving them a strong, sturdy appearance. The coat is predominantly white, with some individuals having black spots on the head or ears. Most Dorpers naturally shed their wool in early spring, as the undercoat becomes denser and closer to the skin. **Growth and Development** One of the key advantages of the Dorper breed is its precocity—meaning it grows quickly and reaches maturity at an early age. Under good feeding conditions, lambs can weigh between 4 to 5.5 kg at birth, and by weaning, they typically reach 34 to 45 kg. They gain around 350 to 450 grams per day during lactation. Adult rams usually weigh between 80 to 85 kg, while ewes range from 60 to 62 kg. By the age of 1 to 1.5 years, they achieve their peak growth, developing a wide chest and deep body structure. **Meat Production Performance** Dorper sheep are highly valued for their superior lamb meat quality. Their meat is tender, juicy, and rich in lean content, often referred to as "diamond-grade meat" internationally. At four months old, the slaughter rate is approximately 51%, with a net meat yield of about 45%. The meat-to-bone ratio is 9.1:1, and the feed conversion ratio is 1.8:1, making them highly efficient for meat production. **Wool Production Performance** Dorpers are sheared 1 to 2 times a year, with adult rams producing 2 to 2.5 kg of wool and ewes yielding 1.5 to 2 kg. The wool is mostly uniform, with some fine fibers and short, soft hairs. The length of the spring fleece is around 6.13 cm, while the autumn fleece measures about 4.92 cm. The wool fineness ranges from 64 to 70, and the average wool yield is 50% to 55%. **Reproductive Performance** Dorper rams reach sexual maturity at 5 to 6 months, while ewes mature at 5 months. Breeding typically begins at 12 to 14 months for rams and 8 to 10 months for ewes. The gestation period lasts about 148.6 days, with a fertility rate of up to 98.4% and a lambing rate of 177% on average. The survival rate of lambs is over 97.2%, and they are known for their strong maternal instincts and milk production, which significantly contribute to lamb survival. **Adaptability** Dorper sheep are highly adaptable and thrive in temperate climates. They are resistant to both heat and cold and can survive on roughage. However, due to their short stature and wide legs, grazing on steep slopes (over 30 degrees) is less ideal. Despite this, they perform well in flat areas, where they graze, feed, and move efficiently. **Economic Value** The genetic stability of the Dorper breed ensures consistent performance across generations. Whether purebred or crossbred, they consistently deliver excellent meat production and adaptability. Compared to other meat sheep breeds in China, they stand out for their superior qualities. Additionally, their hides are of high quality, making them an ideal raw material for tanning.
