The aim of this study was to investigate the potential association between growth hormone GH/AluI and growth hormone receptor GHR/AluI polymorphisms with milk yield and reproductive performances in Holstein dairy cows in Iran. Blood samples of 150 Holstein cows were collected and their genomic DNA was extracted using Gene-Fanavaran DNA extracting kit. Fragments of the 428 bp of exon 5 growth ho...

Five alternative models were applied for analysis of dystocia and stillbirth in first and second parities. Models 1 and 2 were included only to estimate the parameters required for model 4, and models 3 and 5 are included only as comparisons to the model 4 estimates. Variance components were estimated by multi-trait REML, including cows with valid calving records for both parities. For the effe...

Study was conducted on 149 case of cross breed bovine dystocia referred to Department Theriogenology, College Veterinary Medicine and Al-Wihda Cattle station, Baghdad, Iraq. Results showed that 87.5% were successfully relieved by cesarean section (C.S), 85.5% success achieved correction an traction, 71.4% fetotomy 50% hormonal treatment. Most the cases subjected C.S, heifers. Details concerning...

This paper reports results from a long-term experiment with a primary objective to increase twinning rate in cattle at the Roman L. Hruska U.S. Meat Animal Research Center. Survival of singles was 13% higher (P < .01) than that of twins at birth, and the difference in survival in favor of singles was of similar magnitude at 72 h (12.9%, P < .01), 150 d (14.8%, P < .01), and 200 d (15.2%, P < .0...

background: detection of women at risk for dystocia will allow physicians to make preparations and treatment decisions that can minimize maternal and neonatal morbidity. we aimed to determine the risk factors for dystocia in nulliparous women. methods: this case series enrolled 447 nulliparous women who presented with a single pregnancy in the vertex presentation and gestational age of 38-42 we...

A full term primiparous non – descript buffalo was presented with dystocia. It had a history of a train accident that injured pelvis in its early pregnancy. Per vaginal examination revealed narrowed birth canal consequent to mal union of fracture of os coxae confirmed it as dystocia due to narrowed pelvis. A right paramedian laparo hysterotomy was performed and retrieved a dead female calf. Wit...
