Objective: To explore the epidemiological characteristics, the influence on reproductive health and the genetic basis of dystocia – prolonged and difficult labour. Material and methods: The thesis has a retrospective design and is mainly based on a material from an entire cohort of women, extracted from the Swedish Medical Birth Register, who had their first delivery during the years 1973 to 19...
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...
Although fetomaternal disproportion is the major cause of dystocia in heifers, pelvis area (PA) is not recommended as a culling tool due to its relatively low importance and genetic correlation with calf birth weight (BWT), the most important factor associated with dystocia. The objective of this observational study of 484 limited bred yearling beef heifers was to compare the effects of differe...

Provider attitudes about childbearing and knowledge of safer conception at two HIV clinics in Malawi
BACKGROUND There is limited understanding of health care providers' attitudes towards HIV-infected individuals' reproductive choices, as well as knowledge about safer conception. Our study objective was to explore provider-level factors that serve as barriers and/or facilitators to the provision of reproductive and safer conception services for men and women living with HIV. METHODS Twenty-fi...

We collected phenotype data 20 conformation cows analyzed impact trait linear scores calf weight. feet angle, set rear legs, fore udder attachment height da...
In this study 2510 records of reproductive traits from the mating of 879 ewes with 164 rams of Bakhtiari sheep breed, during 1989 to 1997, were used in order to estimate the effects of environmental factors on their reproductive performance. The mean and standard errors of reproductive traits were as follows: conception rate, 0.9±0.01 number of lambs born per ewe exposed, 1.06±0.01 number of la...

During the 1970s new contraceptive options developed and legal abortions became accessible. Family planning clinics targeting young women and men provided advice and assistance on contraception. Today, delayed childbearing, low total fertility rates and increasing use of social oocyte freezing create a need for pro-fertility initiatives. Three years ago we established a new separate unit: The F...
