Sixty eight adult ewes of Zel sheep breed were screened with forced PCR RFLP method for the detection of the FecB gene and its effects on litter size. Genomic DNA was extracted from the blood of 68 Zel matured ewes with litter size varied from 1 to 2 lambs per ewe lambing. Digestion of the FecB gene (190 base pairs) with AvaII restriction enzyme resulted in none carrier 190 bp band wild type in...
The FecB gene has been discovered as an important gene in sheep for its high relationship with the ovulation rate, but its regulatory mechanism remains unknown. In the present study, liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) techniques were adopted to detect the metabolic effects of FecB gene in follicular fluid (FF) and ovarian vein serum ...
The average twin lambing rate of Bayanbulak sheep is 2% to 3%. However, a flock of sheep with a close genetic relationship and an average of 2 to 3 lambs per birth has been found recently. To determine the major genes controlling the prolificacy of the flock in the present study, the flock was designated A while 100 normal Bayanbulak sheep were randomly selected to comprise the control flock B....
ایران یکی از مهم ترین مراکز پرورش گوسفند است. نژاد لری بختیاری از جمله گوسفندان چندقلوزای کشور است. رومانوف نیز نام یک نژاد گوسفند روسی است که دارای رکورد چند قلوزایی می باشد. این دو نژاد از نژاد های گوشتی گوسفند بوده و دارای رشد خوبی نیز می باشند. هدف از این مطالعه بررسی وجود جهش ژن های fecb و igfi در گوسفندان آمیخته رومانوف ولری بختیاری است. بررسی ها نشان می دهد که جهش ژن بورولا، یکی از ژن ها...
RATIONALE The Spanish guideline for COPD (GesEPOC) recommends COPD treatment according to four clinical phenotypes: non-exacerbator phenotype with either chronic bronchitis or emphysema (NE), asthma-COPD overlap syndrome (ACOS), frequent exacerbator phenotype with emphysema (FEE) or frequent exacerbator phenotype with chronic bronchitis (FECB). However, little is known on the distribution and o...
The Small Tailed Han sheep and Hu sheep are two prolific local sheep in China. In this study, the polymorphisms of BMPR-IB (Bone morphogenetic protein receptor IB), BMP-15 (Bone morphogenetic protein 15) and FSHR (follicle stimulating hormone receptor) were investigated to check whether they are associated with litter size in Small Tailed Han sheep and Hu sheep. Consequently, three polymorphism...
the booroola fecundity gene (fecb) and growth differentiation factor 9 (gdf9) gene belong to the transforming growth factor β (tgf-β) superfamily. the mutations of these genes have additive effects on the prolificacy in sheep. the aim of the present study was to determine the possible mutations of fecb and fecgh genes in lory sheep breed of the lorestan province, iran. sixty blood samples were ...
The Booroola fecundity gene (FecB) and growth differentiation factor 9 (GDF9) gene belong to the transforming growth factor β (TGF-β) superfamily. The mutations of these genes have additive effects on the prolificacy in sheep. The aim of the present study was to determine the possible mutations of FecB and FecGH genes in Lory sheep breed of the Lorestan province, Iran. Sixty...
بزهای کاموری، FecB، FecGH، GDF9 هدف: هدف از این مطالعه تعیین وجود جهش‌های FecB و FecGH در بزهای نژاد کاموری استان خوزستان بود. مواد و روشها: در این مطالعه پژوهشی، از 40 راس بز کاموری با حداقل یکبار سابقه دوقلوزایی خون...
شناسایی ژن‌های مؤثر بر چندقلوزایی اهمیت به سزایی در شناخت ذخایر ژنتیکی و برنامه‌ی اصلاح ژنتیکی دارد. از جمله مهم‌ترین ژن‌هایی که بر میزان چند قلوزایی مؤثر هستند می‌توان به ژن‌های FecB، FecG و FecX اشاره کرد. هدف از این مطالعه، بررسی وجود جهش‌های FecB و FecGH در بزهای نژاد لری استان لرستان می‌باشد. بدین منظور از 50 رأس بز لری (با سا...
