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 ...

BACKGROUND In this experiment, abdominal cavity of 518 Iranian Sistani cattle and 498 Brahman cattle were inspected for the presence of Setaria spp. from April 2012 - May 2013. METHODS The species were determined by microscopic examination of the morphological characteristics of the anterior and posterior parts of the parasites and authentic guidelines. RESULTS The overall prevalence of Set...

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...

The use of polymorphic markers in breeding programmes could make selection more accurate and efficient. A total of 324 individuals from six Iranian cattle populations (Sarabi, Golpayegani, Sistani, Taleshi, Mazandarani, Dashtiyari), F1 Golpayegani × Brown Swiss and Iranian buffalo populations were genotypedfor the Pit-1 HinfI and leptin Sau3AI polymorphisms by the polymerase chain reactio...

BACKGROUND Knowledge of linkage disequilibrium (LD) levels among different populations can be used to detect genetic diversity and to investigate the historical changes in population sizes. Availability of large numbers of SNP through new sequencing technologies has provided opportunities for extensive researches in quantifying LD patterns in cattle breeds. The aim of this study was to compare ...

BACKGROUND Parasitological investigations on paramphistomosis were carried out over a 12-month period in the southeast of Iran to determine the prevalence and intensity of this disease. METHODS A total of 1000 cattle, Sistani breed (n= 450) and Brahman breed (n= 550) of all sex and age groups were inspected at random for the presence of paramphistomidae flukes in Zabol slaughterhouse from Dec...

background : in this experiment, abdominal cavity of 518 iranian sistani cattle and 498 brahman cattle were inspected for the presence of setaria spp. from april 2012 - may 2013. methods: the species were determined by microscopic examination of the mor-phological characteristics of the anterior and posterior parts of the parasites and authentic guidelines. results: the overall prevalence of se...

This study was undertaken to estimate the genetic parameters for some reproduction traits in Sistani beef cattle. The data set consisted of 1489 records of number of insemination, calving, and insemination dates in different calving was used. Reproduction traits including calving interval (CI), gestation length (GL), days open (DO), calving to first service (CTFS), first service to conception (...
