چکیده
The current study was conducted in private station located the middle of Iraq by using 100 blood samples from Holstein cows to isolate DNA and determine genotypes TNF-α gene tow regions on reproductive performance. Results showed two alleles with co-dominance three detected 1st position (4th exon), allele frequency 0.695 0.305 for A C respectively. 2nd region (Flank region) 0.64 0.36 G a significant effect polymorphism 4th exon retained placenta rate which differed significantly (P≤0.01) among cow groups, highest recorded AC genotype about 0.24. ovulation weakness rate, CC 0.12. Parturition difficulties , mutant namely,0.18. flank region, GC 0.20.

Polymorphism of SCD1 and DGAT1 Gene in Isfahan Holstein Cows
In this study we estimated the allele and genotype frequencies of SCD1 and DGAT1 gene polymorphism. The analysis was conducted on 408 Holstein cows from five dairy herds in Isfahan province. Genotypes were identified using PCR-RFLP technique. Two genetic variants (A and V) of the SCD1 gene were observed in this experiment. The frequency of A-allele ranged from 0.49 to 0.66, while frequency of V...

Data on the use of breeding records of dairy cattle farm of Fenghuang-shan in Chengdu areas during a period of six years is systematically analyzed. The results show that Holstein heifers have their 1st estrus at an average age of 513.6±46.7 d which is not related to the calving season. Estrus mostly occurs in the months with mild ambient temperature (March, April, May, November and December). ...

Background: Recent studies have shown that the course of cystic fibrosis in patients with this disease differs despite the same mutation in CFTR gene. We aimed to investigate the role of polymorphism in TNF α (-308) and TNF α (-863), and its effect on the phenotype of the patients with cystic fibrosis and progression of disease. Materials and Methods:...
