the aim of this study was to design the base breeding plan in sistani cattle by using of stochastic simulation. for this purpose, three population size (500, 1000, 2000 heads), three levels of herd number (5, 10, 20), two levels of selection intensity (high and low) and two levels of mating method (random and minimum co-ancestry) were combined together and in total 36 scenarios were compared fo...

Bovine leukemia virus (BLV), the causative agent of enzootic bovine leukosis, is an exogenous, B lymphotropic retrovirus belonging to the Retroviridae family that induces persistent lymphocytosis in cattle and sheep. PCR has proven to be particularly suitable for investigating herds of cattle with a very low incidence of BLV infection and for clarifying doubtful serological results obtain...

the aim of this study was to analyze the polymorphisms existing in the 5´ flanking region, exonic, and some parts of the intronic regions as well as methylation analysis of the ednrb gene in cattle and goat. these regions were sequenced in three different breeds of cattle including sistani, golpayegani, and holstein and were compared with that of marghoz goat. the results identified that this g...

The objective of the present study was to determine polymorphism within the promoter region of somatotropin receptor genes in indigenous Sistani cattle (Bos indicus) and associations between this polymorphism and breeding value of birth weight. The pedigree structure was included by considering 1173 animals with 600 progeny birth weight data obtained from a Zhark breeding station in Sistan and ...

in recent years, the relationship between insertion and deletion (indel) polymorphisms in promoter region (23 bp) and intron 1 (12 bp) of prnp gene (prion protein coding gene) and their relationship to susceptibility of classical bovine spongiform encephalopathy (bse) have been reported. insertions of these two polymorphisms increase resistance to classical bse, while the deletions of these two...

Bovine spongiform encephalopathy (BSE) is a fatal infectious neurodegenerative disease in cattle, characterized by the accumulation of an abnormal, proteaseresistant prion protein (PrPSc) in the brain. BSE is similar to scrapie in sheep and goats and Creuzfeldt-Jakob disease in humans. Susceptibility in cattle hasbeen shown to be under the influence of two polymorphic locations, which are...

UNLABELLED Background : Congenital heart disease (CHD) is the most common congenital anomaly in newborns. This study was performed to determine the live birth incidence of CHD by ethnicity and sex in Gorgan, Northern Iran. METHODS In this longitudinal, hospital-based study, 18162 live births in Dezyani Hospital in Gorgan, North of Iran, were screened for CHD, from 2007 through 2009. Clinical ...
