this study aimed to identify genes that show signatures of selection for mutations in iranian native cattle breeds. the data consisted of genotypes for ~777962 snp markers of 90 animals from eight iranian native cattle breeds distributing over the country. therefore, the aim was to identifying divergently selected regions of the genome. study of population differentiation across the genome usin...
The technical efficiencies of a sample of extensive Iranian cattle farms collected by Ministry of Agriculture were analyzed using a nonparametric Data Envelopment Analysis (DEA) model. Mean pure technical efficiency in a DEA model in which all variables were normalized with the number of cows was 0.79, indicating that there is ample potential for more efficient input utilization in cattle farmi...
In this study, we analyzed complete mtDNA sequences variation and genetic relationship among taurine, indicine and Bison groups. In total, 107 sequences from different breeds, 45 European (45 Italian), 16 Middle East Asian (seven Iranian and nine Iraqi), 41 Northeast Asian (34 Korean and seven Japanese), two Nellore (Bos indicus) and two American Bison bison (Ame. bison) were obtained from Gen-...
The aim of this study was correlation determination between fat putrefaction indices and antioxidative enzymes in chicken, cattle and camel meat during refrigerated storage. Longissimus dorsi muscle of three Iranian dromedary one humped camel and three Holstein cattle and breast muscle of three broiler breeder chicken were obtained from the carcasses 3 days postmortem. The samples were ground a...
The objective of this study was to develop a method for calculating economic values of clinical mastitis (CM) and somatic cell score (SCS) for inclusion in a dairy cattle breeding goal in the context of a country where farm production and economic data are scarce. In order to calculate the costs and derive economic values for SCS, a new model, 'milk collection method', has been developed and wa...
BACKGROUND This study aimed at investigating the prevalence and risk factors of bovine thelaziosis, performed in the southeast of Iran, an endemic area for Iranian Sistani cattle. METHODS Between September 2012 to October 2014, 1924 cattle, Sistani breed (n= 1235) and Brahman breed (n=689) of all sex and age groups collected from Sistan and Baluchestan Province were examined using visual obse...
BACKGROUND The gullet worm, Gongylonema pulchrum Molin, 1857, is a thread-like spirurid nematode found in a variety of mammals worldwide. Its incidences in Iranian cattle of different breed or age have not been reported. The aims of the present study are to disclose the infection status of G. pulchrum in cattle slaughtered in northern region of Iran. METHODS Full-length esophagi of cattle of ...
BACKGROUND Knowledge about the amphistomid fauna in Iranian domestic ruminants depends on the studies conducted almost 30 years ago. The last situation in cattle is introduced here in the provinces in south coast of Caspian Sea. METHODS Amphistomid species were collected from cattle at slaughter houses of the provinces Gilan and Mazanderan in 2010. Median sagittal sections were prepared by th...
