| Abstract: | Super Merino sheep is our country of the ultrafine fine wool sheep varieties breed in recent years.In order to realize the genetic parameters of main economic traits and population gain speed and direction, this study collected 9 140 identification records, 7 158 shear-weighing records and 5 540 mating and lamping records of this flock from 2014 to 2020.DMU software was used To estimate the genetic parameters and genetic trend analysis of Super Merino wool traits and growth traits by using AIREML module combined with EM algorithm and single trait animal model(ySL,yGFW,BW,yBWPR,ADG,yBWPO),results show that this trait heritability range between 0.22～0.32, the yBWPO belongs to high heritability traits(0.32±0.04),ySL(0.22±0.03)、yGFW(0.22±0.03)、BW(0.25±0.04)、yBWPR(0.25±0.03)、ADG(0.27±0.04) and were the medium heritability traits. From 2013 to 2019, the traits studied generally showed an slow rising trend, and the breeding value of each trait increased significantly.It was further proved that there were some achievements in breeding and genetic gain of Super Merino sheep. According to the trend of genetic changes, it could provide data basis and theoretical basis for the development of comprehensive selection index and subsequent breeding program. |
