"With the South African black-headed Dubo sheep as the male parent and the Shandong province local small-tailed Han sheep as the female parent, after 18 years of painstaking research, we are the first in the country to cultivate the first high-yield multi-fetal lamb new breed - Luxi black-headed sheep. This variety is suitable for the climatic conditions and housing feeding in the northern agricultural areas of China, and its meat production and reproductive performance have reached the international leading level. This year the Ministry of Agriculture issued a new breed certificate for livestock and poultry, which became the first national trial sheep in the northern agricultural region of China. New varieties." On March 29th, at the press conference of the new scientific and technological achievements of the Shandong Academy of Agricultural Sciences "Luxi Blackhead", the president Wan Shubo released the news to the society.

According to Zhang Guixiang, deputy director of the Animal Husbandry Department of the National Animal Husbandry Station, the national lamb production in 2017 reached 4.68 million tons, an increase of 77.2% over 2000. It is the country with the largest amount of sheep stocks, slaughter and lamb production in the world. In 2017, China's mutton production accounted for 5.56% of the total meat production. "The birth of Lu Xi black sheep shows that the independent innovation ability of China's meat sheep breeding will play an important role in improving the core competitiveness of China's meat sheep industry and accelerating the construction of a modern animal husbandry country." Zhang Guixiang said.

Wang Jinwen, leader of the breeding team of Luxi Blackhead, told reporters: "We applied the main genetic screening technology in molecular breeding to the breeding of this species for the first time, and established the core breeding population of Luxi blackhead with individuals carrying the main gene of FecB. It accurately guarantees the genetic traits of the bred breeds, especially the stability of the multi-lamb traits, so that all production performances reach the advanced level of high-quality broiler sheep."

"China's mutton sheep have a small number of excellent varieties cultivated independently, low coverage of improved varieties, mainly exotic species of breeding sheep, and lack of core competitiveness of domestic varieties, which are unfavorable factors restricting industrial development. Under this background, the cultivation of black sheep in Luxi Success has an important milestone.” Jin Hai, chief scientist of the National Meat Sheep Industrial Technology System, believes that Luxi Blackhead has pioneered the cultivation of new breeds of mutton sheep in the Central Plains region, providing useful experience for cultivating new breeds of mutton sheep using local sheep germplasm resources. .
