this experiment was conducted to investigate the effect of feeding frequency and oil supplementation to the diet on performance and feeding behavior of lactating dairy cows. twenty four lactating holstein cows, 12 primiparous, (bw= 626±58 kg and dim= 195±44 day) and 12 multiparous, (bw= 617±25 kg and dim= 207±39 day) were randomly assigned to four diets contained 2.5 percent supplemental oil or...

OBJECTIVE To evaluate the association between median episiotomy and severe (third- and fourth-degree) perineal lacerations in primiparous women. DESIGN Retrospective cohort study. SETTING University-affiliated hospital providing secondary obstetric care in Quebec City. PATIENTS A total of 6522 primiparous women who gave birth vaginally to a single live baby in cephalic position between 19...

Pregnancy is a well established protective factor against breast cancer. One explanation for protection is the increased differentiation status of the parous epithelium. However, this does not explain the association of parity with increased aggressiveness of breast cancers, particularly cancers that occur soon after pregnancy. Because tumor aggressiveness can be influenced by the cell populati...

BACKGROUND The delivery of many children at short interval is associated with micronutrient depletion and weight gain. However, the relationship between the levels of the micronutrients and the body weight is yet to be ascertained. OBJECTIVES To determine the relationship between parity, body weight and some antioxidant vitamins in non-pregnant Nigerian women. PATIENTS AND METHODS Randomly ...

To compare 2 strategies for systematically resynchronizing ovulation, lactating Holstein cows (n = 763) at various days in milk and prior artificial insemination services were assigned randomly at timed AI (TAI) to receive the first GnRH injection of Ovsynch 26 (D26) or 33 (D33) d after TAI to resynchronize ovulation (Resynch) in cows failing to conceive. Cows in the D26 treatment received GnRH...

Pelvic Organ Prolapse (POP) is a major clinical burden affecting 25% of women, with vaginal delivery a major contributing factor. We hypothesised that increasing parity weakens the vagina by altering the extracellular matrix proteins and smooth muscle thereby leading to POP vulnerability. We used a modified POP-quantification (POP-Q) system and a novel pressure sensor to measure vaginal wall we...

The body condition constraint and the experience condition constraint hypotheses have both been proposed to account for differences in reproductive success between multiparous (experienced) and primiparous (first-time) mothers. However, because primiparous mothers are typically characterized by both inferior body condition and lack of experience when compared to multiparous mothers, interpretin...

OBJECTIVES This study investigated the self-reported prevalence and impact of low back pain (LBP) during pregnancy in primiparous and multiparous women, and their treatment-seeking rationales and experiences, including their use of physiotherapy. METHODS A sample of 105 post-partum women was recruited. All participants answered a questionnaire; women who experienced LBP during pregnancy (n=71...
