First, the appearance characteristics
The body is large, the body is good, the body is long, wide and deep. It is shaped like a barrel and has short bones. The coat is pure white, and the hair is divided into black and white. Most sheep have natural hair loss after the beginning of spring. Cover hair close to the skin.
Second, growth and development
Precocity is the biggest advantage of Dubo Yang. Under medium and above nutrient conditions, lambs weigh 4 to 5.5kg, weaned weight 34 to 45kg, average daily gain 350 to 450g during lactation, 80 to 85kg of ram weight, 60 to 62kg of ewes, and 100 weight of adult ram ~ 120kg, ewe 85 ~ 90kg, before the age of the highest growth, longest, 1 ~ 1.5 years old main growth wide and deep, large bust.
Third, meat production performance
Dorper sheep is particularly good for fat-producing lamb meat. Its meat is delicate, succulent, fresh in color and high in lean meat. It is internationally known as "diamond-grade meat." The slaughter rate at 4 months was 51%, the net meat rate was about 45%, the meat to bone ratio was 9.1:1, and the feed weight ratio was 1.8:1.
Fourth, wool production performance
1 to 2 times of hair shearing, 2 to 2.5 kg of adult male rams, 1.5 to 2 kg of ewes, mostly homogenous hairs, individual fine half hairs, short and fine hair, 6.13 cm spring fur, autumn Hair 4.92cm, wool body fineness of 64, a few up to 70 or more; net hair rate average 50% to 55%.
Fifth, reproductive performance
The rams are sexually mature from 5 to 6 months of age, and the ewes are sexually mature at 5 months of age. The male and female ewes are 12 to 14 months old and 8 to 10 months old. The gestation period is 58%. The yield of the ewe was 66%, and the rate of conception in the two periods reached 98.4%. The average period of gestation was 148.6 days. The lambing rate was 177% on average, and the average survival rate of the lambs was 97.2%. The single-born lamb was 100%. Sheep are estrus all year round. They are mostly from August to April in the following year. They are concentrated from August to December. The lambing interval is 8 months and it can be produced in 2 years and 3 years. This breed has a very good nanny and lactation, which is an important factor in the high survival rate of lambs.
Sixth, adaptability
The Dubo sheep have been widely used in temperate climates across the country. They all show good adaptability. They are resistant to heat and cold, and tolerant to roughage. However, due to their short body and wide legs, grazing on slopes above 30 degrees is slightly poor, but they are more gradual. Grazing areas are very good for grazing, feeding and walking.
Seven kinds of value
The genetic character of Dorper sheep is very stable. No matter whether it is a progeny or an improved offspring, it shows excellent production performance and adaptability, especially meat production performance. It is unmatched for the meat sheep breeds imported and produced in China at present. . This type of leather is excellent and it is also an ideal raw material for tanning.
