BACKGROUND Cancers of gastric and esophagus are the most frequent gastrointestinal (GI) tract cancers in Iran. This study aimed to analyze time trends of GI tract cancers in Guilan province by gender and age to provide solid scientific evidence for cancer prevention and control. MATERIALS AND METHODS The data were obtained from the Guilan Cancer Registry System and Guilan Provincial Health Ce...

871 mesenteric lymph nodes taken from 110 native cattle from Urmia slaughter-house with differentages were examined for Linguatula serrata infection. The lymph nodes were studied based on their colourand consistency. 44% of the cattle were found positive for L. serrata infection. The number of parasitesisolated from each infected lymph node varied from 1 to 69 with a mean of 5.48. There were no...

efficiency is defined as a concept that determines the input output ratios in an economic system. data envelopment analysis method is a useful tool to estimate the efficiency of a unit. the purpose of this study was to estimate technical efficiency and to determine return to scale of holstein cattle farms in guilan province. therefore, the information including the number of labor and dairy cow...

this study was carried out to determine the prevalence and intensity of amphistomiasis in native cattleand mixed breed holstein from mazanderan province, in the north of iran in association with sex, age, breedand season. during the 4 seasons of 2008, at meat inspection the rumen and reticulum of 132 native cattleand 104 mixed breed were examined by naked eye for amphistomiasis. all amphistomes...

This investigation was conducted to identify polymorphism of the leptin gene in Holstein cows, Mazandarani native cattle and buffaloes by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). The frequencies of A and B alleles were 0.4 and 0. 6 in Holstein cows, 0.56 and 0.44 in Mazandarani native cattle, 0.61 and 0.35 in buffaloes, respectively. The heterozygote genoty...

In order to clarify the origin and genetic diversity of cattle in North Eastern Asia, this study examined mitochondrial displacement loop sequence variation and frequencies of Bos taurus and Bos indicus Y chromosome haplotypes in Japanese, Mongolian, and Korean native cattle. In mitochondrial analyses, 20% of Mongolian cattle carried B. indicus mitochondrial haplotypes, but Japanese and Korean ...

The main objectives of this study were to determine the occurrence and potential causative factors of Immune-mediated hemolytic anemia (IMHA) in native cattle and water buffaloes from southwest of Iran. Fifty-three anemic animals (37 cattle and 16 buffaloes) were studied. A full clinical history and physical examinations were undertaken for all animals. Four clinically healthy cattle and four h...

Neospora caninum is a worldwide distributed pathogen which causes abortion in cattle leading to economic loss in the cattle industry. The aim of this study was to determine the seroprevalence of N. caninum antibodies in the native cattle slaughtered in various areas of Kurdistan province (western Iran) from September 2010 to September 2011. Serum samples from 368 cattle slaughtered in seven sla...

Cattle grazing and invasion by non-native plant species are globally-ubiquitous changes occurring to plant communities that are likely to reverberate through whole food webs. We used a manipulative field experiment to quantify how arthropod community structure differed in native and non-native California grassland communities in the presence and absence of grazing. The arthropod community was s...

This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to p...
