Maternal age at first childbirth has increased in most developed countries in the past 20 years. The purpose of this study is to investigate effects of maternal age at delivery and parity on successful initiation of exclusive breastfeeding (EBF). This retrospective study investigated 1193 singleton dyads with vaginal-delivered at 37-42 gestational weeks during January and December in 2011 at on...

abstract background: postpartum blues is a transient change of moods occurring in the first few days after delivery. the present study aimed to investigate the effect of religious doctrines on postpartum blues in primiparous women. materials and methods: in this randomized controlled tria1, 84 primiparous women who had average or weak religious attitude were randomly divided into intervention a...

An experiment was replicated over 2 yr to determine the effect of additional RUP and dietary fat from dried distillers grains plus solubles (DDGS; n = 2) or wet corn gluten feed (WCGF; n = 2) before breeding on primiparous cow reproduction and calf production. Over 2 yr, 134 postpartum, primiparous cows (429 ± 5 kg initial BW) were fed 1 of 2 isocaloric, approximately isonitrogenous diets in 1 ...

PURPOSE To describe patterns of prescribed drug use over time among primiparous women in Denmark. METHODS Through the Danish Medical Birth Registry, we identified all primiparous women giving live birth or stillbirth at ≥ 22 gestational weeks in northern Denmark, from 1999 to 2009. From the Aarhus University Prescription Database we obtained information on the women's prescriptions for reimbu...

BACKGROUND Studies on the primiparous mothers' decision on delivery method are limited. AIM The aim of his study was to determine the factors that influence the choice of delivery method by Iranian primiparous women. METHODS This cross-sectional study was conducted in April through September 2014. Participants were 460 primiparous women in 8 hospitals of 4 cities in Iran. Finally, 230 cesar...

Calving ease is of economic importance in dairy cattle and should be considered in breeding programs. Economic values of direct and maternal calving ease were derived based on cost-benefit analysis and gene flow methodology. Marginal returns from dystocia reduction in primiparous dams were -$43 per phenotypic standard deviation compared with $300 for production. For an average mate, numbers of ...

METHODS A retrospective cohort study of the 38,484 primary cesarean deliveries among the 228,562 deliveries at sites participating in the Consortium on Safe Labor from 2002 to 2008.

OBJECTIVE To describe the use of episiotomy among Vietnamese-born women in Australia, including risk factors for, and pregnancy outcomes associated with, episiotomy. METHODS This population-based, retrospective cohort study included data on 598 305 singleton, term (i.e. ≥ 37 weeks' gestation) and vertex-presenting vaginal births between 2001 and 2010. Data were obtained from linked, validated...

The experiment was conducted in primiparous sows to determine whether progesterone supplementation during early pregnancy could improve embryonal survival and to confirm a functional relationship between progesterone concentrations in the postovulatory period and embryonal survival. Thirty-four primiparous sows were fed for ad libitum intake from farrowing to d 21 of lactation, restricted to 50...

The objective was to evaluate the effect of body condition score (BCS) at 30 days before calving (-30 days) induced by a differential nutritional management, parity and week of lactation (WOL) on milk yield and composition, and milk casein and fatty acid composition. Primiparous and multiparous Holstein cows with high BCS (PH, n = 13; MH, n = 9) and low BCS (PL, n = 9; ML = 8) under grazing con...
