the ultrasonic measurement of the fetal femur length is a sensitive and precise variable for estimation of fetal growth and development. tlte objective of this study was to predict gestational age in fetuses older ttian twenty-four weeks of gestation by ultrasonic measurement of the femur length. in this study, pregnant mothers were identified by the criteria of normality, such as well-known lm...

488 gestations (309 Large White and 179 Landrace) the size of all litters resulting from services which occurred between January 1967 March 1970 were analysed. The mean gestation length was 113.96 days for 113.74 Landrace while values litter 9.14 9.58 respectively. There a significant negative correlation these two traits in both breeds (P 0.01). A slight non-significant seasonal effect 0.10) s...

Constraints to maximal productivity from twinning in beef cattle include increased incidence of dystocia and retained placenta, longer postpartum interval, and lower conception rate. Incidence and cause(s) of the shorter gestation length and of the increased retained placenta and dystocia associated with twinning were evaluated for 3,370 single and 1,014 twin births produced in a population of ...

PARTICIPANTS, METHODS, AND RESULTS In a cohort of 14 193 men and women born in Uppsala in 1915–1929, we studied the associations of fetal growth rate and length of gestation with the risk of death from ischaemic heart disease (ICD 7: 420–422; 8 and 9: 410–414; 10: I20–25) and cerebrovascular disease (ICD 7: 330–334; 8 and 9: 430– 438, 10: I60–69). Occlusive strokes include ICD7: 332–334, ICD8: ...
