Study of the Relationship between Some Genetic Markers and Some Productive Traits of Arabi Sheep in the Steppe of Muthanna

Abstract

The study carried out in the first research station to the College of Agriculture-Al-Muthanna University, 12 km south west of Muthanna district and laboratories specializing in molecular genetics for the period from 15/11/2017 until 30/4/2018 in order to determine the relationship between genetic markers BM1258 and INRA023 with genotypes (90/125,120/135,95/140 and 100/90) and (190/220.180/200 and 185/170) bp Respectively and the production of milk and Its components the following are the most important results obtained: The presence outweigh the significant (P≤0.05) for marker BM1258 in ewes carrying genetic site 90/125 bp in the total production of milk and the length of the milking season the ewes bearing on others local 120/135 , 95/140 and,100/90 bp .while outperformed significantly (P≤0.05) ewes 120/135 bp genetic location in the proportion of fat significantly milk ewes bearing two hereditary 90/125 and 95/140 bp, which varied among them. The presence outweigh the significant (P≤0.05) for marker INRA023 in ewes bearing site genetic 185/170 in the total production of milk and the length of milking the ewes carrying two 190/220 and 180/200 season, while the superiority of ewes same location genotype 180/200 in the percentage of milk fat. Affected the results and there is a significant difference (P≤0.05) for Marker INRA023 in ewes same location genotype 180/200 bp in the proportion fat solids and protein content.
