The primary objective of this field trial was to determine the effects of interval to AI on conception rates of dairy cows identified as high activity using the Select Detect activity system. The Select Detect system uses neck-mounted sensors to scrutinize acceleration and intensity of movement with continuous 24-h surveillance of estrous related activity. Farm personnel inseminated cows at ran...
Over recent decades there has been a considerable increase in the mean age at which mothers in the industrialized world give birth to their first child. For example, since 1990 in the USA, the number of pregnant women aged 45–49 years has increased 190% w2x. Similarly, there is intense debate on the increasing proportion of cesarean deliveries; however, there is little recognition of the connec...
The objectives of this study were to determine the incidence UI in a large cohort primiparous women before and during pregnancy over course 30-months postpartum, identify risk factors for after pregnancy. Nulliparous aged 18–35 years with singleton pregnancies interviewed their third trimester asked about urinary incontinence (n = 3001). After delivery these at 1, 6, 12, 18, 24 postpartum occur...
This study aimed to determine if 200 μg of GnRH (gonadorelin hydrochloride) would increase ovulatory response and pregnancies per AI (P/AI) compared with 100 at the first breeding-Ovsynch a Double-Ovsynch program (DO) in lactating Holstein cows. Weekly cohorts primiparous (n = 719) multiparous 1,191) cows submitted DO [GnRH – 7 d PGF2α 3 (G1) (PG1) 1 ~32 h (G2) ~16 TAI] for timed-artificial ins...
BACKGROUND The objective of the present study was to evaluate the effect of the two methods of delivery, "hands-on" vs. "hands poised", on perineal trauma and delivery outcome in primiparous women referred to Shariati Hospital of Isfahan during 2007-2008. METHODS In a clinical trial study, 100 low risk primiparous pregnant women were randomly assigned to two hands-on and hand-poised (hands-of...
OBJECTIVE To evaluate the utility of magnetic resonance imaging (MRI) in diagnosing structural injury in primiparous women at risk for pelvic floor injury. METHODS This was an observational study of 77 women who underwent 3T MRI after delivery. Women were operationally defined as high risk (n = 45) for levator ani muscle tears (risk factors: second-stage labor > 150 min or < 30 min, anal sphi...
More than 30% of all pregnancies in the UK require some form of assistance at delivery, with one of the more severe forms of assistance being an emergency Caesarean section (ECS). Previously it has been shown that the likelihood of a delivery via ECS is positively associated with the birth weight and size of the newborn and negatively with maternal height. Paternal height affects skeletal growt...
