In this study, LHb gene polymorphism was analyzed by the sequencing technique, SNP mutation sites of LHb gene were detected in five sheep breeds including Lanzhou large-tailed sheep, small-tailed han sheep, Mongolian sheep, large-tailed han sheep and Yuxi fat-tailed sheep, in order to further provide reference to investigate the genetic mechanism of reproductive performance in sheep.
In this study, SNP mutation sites of LHb gene were detected in Lanzhou large-tailed sheep, large-tailed han sheep, Yuxi fat-tailed sheep, small-tailed han sheep, Mongolian sheep and other sheep breeds in order to provide reference to verify the genetic mechanism of reproductive performance in sheep.
Large-tailed han sheep, small-tailed han sheep, Mongolian sheep, Lanzhou large-tailed sheep and Yuxi fat-tailed sheep were selected, thirty each.
The establishment and biological analysis of cell lines of Angora goat could facilitate the conservation and utilization of genetic resources in endangered goats, such as cell lines of Mongolian sheep and Liaoning cashmere goat established in our laboratory (Liu et al.
A: SDS-PAGE electrophoresis of LDH, 1,2 Wuzhishan miniature pig, 3,4 Large white pig, 5,6 Luxi cattle, 7,8 Piemontese Bovine, 9,10 Angora goat, 11,12 Mongolian sheep; B: SDS-PAGE electrophoresis of MDH, 1,2 Suffolk sheep, 3,4 Texel sheep, 5,6 Poll Dorset sheep, 7,8 Mongolian sheep, 9,10 Fat-tailed Sheep, 11,12 Mongolian sheep,13,14 Jining black goat, 15,16 Angora goat.
Establishment and Characterization of a fibroblast cell line derived from Mongolian sheep.
Thus, FecB mutation exists in Mongolian sheep
with the genetic basis of high fertility, and breeding a line with high fertility is possible.
These are not only influenced by Mongolian sheep, Tibetan sheep and Kazakh sheep of China, but also had the genetic relationship with the breeds of other neighbor countries.
2005 reported previously, suggested that Xinjiang sheep breeds are mainly maternally originated from Kazakh and Mongolian sheep in China.
Previous studies reveal that Xinjiang local sheep breeds share the same haplotypes with other sheep breeds of China and belong to Kazakh groups and also have close genetic relationship with Mongolian Sheep (Yu et al.
It has been reported that two million mongolian sheep
were starved each year and the remaining ones may lose 20%-35% of their body weight during pregnancy and lactation (Ma et al.
