pedigree information of iranian holstein dairy cattle, collected via animal breeding centre of iran from 1971 to 2007, were utilized to describe the reasons for the increasing inbreed coefficient. inbreeding coefficient (f) and pedigree completeness (pci) of all the available cattle were found out using a pedigree structure of 883713 animals. the herds with pci of above 0.85 were picked out and...
To visualize the structure of Iranian chemistry scientific publications in SciSearch, 43 Iranian and International chemists were identified. They were the highly cited scientists in 7682 Iranian chemistry publications (defined as an article with at least one Iranian author address) indexed in Science Citation Index during the period from 1990 to 2006. Co-citation data for these authors from the...
OBJECTIVE The aim was to evaluate gender differences in depression scores of Iranian and German medical students. METHODS Two hundred Iranian medical students (100 men and 100 women) and 200 German medical students (100 men and 100 women) were selected randomly and completed the English form of the self-rating Beck Depression Inventory (BDI). RESULTS Analysis gave a mean rating of 10.7 ± 6....
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...

An unusual occurrence of actinobacillosis was diagnosed in 4 heifers aged 8-15 months and 2 cattle in a dairy herd with 190 Iranian Holstein breed. Anorexia, dysphagia, drooling of normal or foodtinged saliva and presence of warts-like lesions on the dorsal surface of tongue shaft were observed in a 15-month-old heifer without showing protrusion of tongue or presenting woody tongue and no invol...
Dairy cattle breeding programs have been based in the selection for traits related to milk production. In this research a data set of 63 herds of East Azerbaijan province Holstein cattle, collected during 2002-2013 by the Iranian Animal Breeding Center was used to estimate the repeatability and heritability of three traits of economic importance. Genetic parameters for first three lactations of...

Using monthly test day records the genetic parameters of Iranian Holstein cattle in first lactation were studied. Data of 277400 test-day milk records from 65320 cows and 2210 sires were analyzed by an animal random regression model using restricted maximum likelihood methodology. The model included herd-test-date, interaction between year-season of calving, days in milk (linear and quadratic) ...
