چکیده

the present study was aimed to examine the association of bovine follicular stimulating hormone gene polymorphism with sperm quality traits including sperm volume (sv), sperm concentration (spco), total sperm (ts), fresh sperm motility (fsm), total fresh motile sperm (tfms), post thaw sperm motility (ptsm), total post thaw motile sperm (tptms), number of produced payout (npp), number of fresh motile sperm in each milt ejaculation (nfmse), motility before and after the freezing (mbatf) and number of post thaw motile sperm in each milt ejaculation (nptmse).we used polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) in 83 bulls belonging to two progeny test center. the frequency of the a (psti+) and b (psti-) alleles were 0.675 and 0.325, respectively. the genotype frequency for aa and ab were 0.35 and 0.65, respectively. the bb genotype was omitted for analysis.mixed and probity models analyses of sperm quality traits considering genotype and environment as fixed effects and animal as a random effect suggested that sire was a significant source of variation (p

The Association of Bovine Osteopontin (OPN) Gene with Milk Production Traits in Iranian Holstein Bulls

Background: The Osteopontin (OPN) is a highly phosphorylated glycoprotein in numbers of bovine tissues and milk. OPN has been reported to be associated with milk production in cattle. Objective: The genotype and allelic frequencies for OPN and its association with milk production will be evaluated in Iranian Holstein Bulls.   Materials and Methods: Bulls DNA (100) was isolated. Oligo was used f...

Single nucleotide polymorphism of the lactoferrin gene and its association with milk production and reproduction traits in Iranian Holstein cattle

Bovine lactoferrin (LTF) is a member of the transferrin family of iron-binding proteins. This protein is present in a wide variety of biological fluids and shows important physiological functions in body. In this study, 404 blood samples were collected from Holstein dairy farms in Iran. A 301 bp fragment of intron 6 in bovine LTF gene was amplified and the animals were genotyped using polymeras...

Quantitative traits locus for milk production traits has been described on centromeric end of bovine chromosome 14. Reports name the acyl coA: diacylglycerol acyltransferase (DGAT1) gene as a potential candidate gene with dinucleotide substitution (AA to GC) in exon VIII which causes the change of lysine to alanine in amino acid (K232A).The aim of the present study was to estimate the frequency...

Single nucleotide polymorphism of FGF2 gene in Iranian Holstein proven bulls

Fibroblast growth factor 2 (FGF2) serves in the uterine endometrium during estrous presenting in the bovine mammary gland which is responsible to express interferon-T (IFNT), and is an important agent to encourage the continuation of pregnancy in the ruminants. Significant associations have been found between genes affected by IFNT and genes that are responsible for milk production traits. Seme...
