PURPOSE To examine the uterine involution period after uncomplicated delivery in primiparous and multiparous women. METHODS Longitudinal prospective study. Repeated parameters were measured and endometrial contents and diastolic notch were observed. Measurements of primiparous and multiparous women were carried out after labour on the 1st, 3rd, 10th, 30th, 42nd, and 60th postpartum days. The ...

Multiparity is an independent risk factor for obesity in parous females. In addition to being a health issue for the mother, offspring of multiparous females may also be at risk for obesity later in life. The aim of the current study was to establish a mouse model that mimics the human pathology of multiparity and determine the effects of multiparity-induced obesity (MIO) on offspring in adulth...

Serum estradiol (E2) and progesterone (P4) levels were measured by chemiluminescence immunoassay (CLIA) during consecutive reproductive states in Mongolian gerbils. The results show that E2 and P4 levels throughout the estrous cycle in Mongolian gerbils peaked at proestrus and estrus, respectively. During gestation in primiparous and multiparous gerbils, E2 levels reached a small peak on day 6 ...

In order to investigate the relationship between insulin to glucagon ratio and metabolic factors in transitional period of dairy cows, 28 cows heifers with body condition score of 3.25- 3.75 were selected. Dairy cows received close up diet, from 21 days prepartum until parturition and lactation diet according to nutritional requirements after parturition. Blood was sampled at 10 days before and...

In dairy cows, milk yield increases rapidly after parturition until a peak at around wk 6 of lactation. However, the description of the shape of the lactation curve is commonly based on weekly average milk yields. For a more detailed analysis of the milk production curve from the very beginning of lactation including the colostral period and the effect of colostrum yield on further lactational ...

Two hundred sixty-two sows were used to investigate the effects of boar exposure during the last week of nursing (BPRE) and after weaning (BPOST) on the return to estrus. Because approximately one-half of the sows were weaning their first litter, a third factor, primiparous vs multiparous (LITT), was considered in the statistical analysis. To evaluate the effect of treatment on ovarian activity...

Multiparous (n = 26) and primiparous (n = 18) Holstein cows were fed prepartum and postpartum total mixed diets that were, or were not, supplemented with a yeast culture (YC) for approximately 23 d prepartum and 56 d postpartum. Multiparous cows supplemented with YC selected a prepartum diet higher in CP than did unsupplemented cows, although prepartum performance of cows of both parities, as a...

Ovarian hormone elevations are associated with enhanced learning/memory. During behavioral estrus or pregnancy, progestins, such as progesterone (P(4)) and its metabolite 5 alpha-pregnan-3 alpha-ol-20-one (3 alpha,5 alpha-THP), are elevated due, in part, to corpora luteal and placental secretion. During 'pseudopregnancy', the induction of corpora luteal functioning results in a hormonal milieu ...
