Description
Technical Field
The invention belongs to the technical field of animal breeding, and particularly relates to a method for breeding a new strain of meat sheep.
Background
Sheep, Ovisaries (L innaeus, 1758), a common raised animal of the genus bovidae, full body, thick body hair, short head, male sheep have a spiral large angle, and are very powerful but have a good looking effect, female sheep have no angle or only a small angle, the hair color is white, the sheep are domesticated first in the southwest asia region about 11000 years ago, the sheep are raised all around the world, the temperament is timid and mild, the domestication is easy, most of the currently highly domesticated raised varieties are oestrous all the year round, local grazing varieties are seasonal oestrous, most of the oestrous in autumn and winter, the pregnancy of female sheep is 145-152 days, 1-5 sheep are produced per fetus, the life is 10-15 years, the sheep are thirst resistant, products such as meat, fur and the like can be provided for human beings, the sheep are fresh and tender, and the sheep are good in nature, the most of the raised in interior Mongolia country, the green sea, and the like.
The Safuke sheep is the meat variety with the largest physique and weight in the world at present, is early-maturing and grows quickly. The Dorper sheep has large physique, similar barrel shape and fast early development, and is a meat sheep variety widely distributed. With the rise of mutton sheep fever, foreign mutton sheep varieties such as Wudao Saite, Charolais, Germany merino, Safuke, Texsel and Dorper, as well as domestic small tailed Han sheep and Hu sheep are introduced in sequence all over the country, the economic hybridization gradually enters the promotion radiation from the experimental demonstration, but the economic hybridization system for producing high-quality lamb is still in the primary stage, the optimal hybridization combination screening of different production purposes and adaptation to different ecological conditions is still mostly in the experimental optimization stage, and the establishment of a mutton sheep hybridization mode is generally stopped in the binary hybridization stage. Ternary and quaternary hybridization patterns are being explored experimentally.
