Górski K., Hasiec M., Zielińska-Górska M., Fülöp F., Misztal T. (2017): Up-regulation of oxytocin receptor gene and protein in the sheep anterior pituitary by a dopamine derivative (salsolinol). Czech J. Anim. Sci., 62, 150−156. Specific oxytocin receptors (OTR) have been identified in the anterior pituitary (AP), and their expression has been shown to change in relation to the animal physiolog...

To determine the duration of lactation which is associated with weight loss in rural Bangladeshi mothers and also to determine the relationship with consumption patterns of principal food items, a cross-sectional study was carried out among 791 lactating rural Bangladeshi mothers aged 18-40 years. Results were compared with 333 non-pregnant and non-lactating mothers of a similar age group. The ...

Pregnancy and lactation are times of prolonged physiological changes affecting the neuroendocrine and immunological systems. One well-characterized change is the neuroendocrine hyporesponsiveness to acute stressful stimuli. We have now designed studies to see whether there is an alteration in the response of the hypothalamic-pituitary-adrenal (HPA) axis to an immunological inflammatory challeng...

Activation of the hypothalamo-pituitary-adrenal (HPA) axis by psychosocial stress is attenuated during lactation. We tested the hypothesis that lactating ewes will have attenuated HPA axis responses to isolation and restraint but will have greater responses to predator stress in the form of barking dogs. We imposed two 4 h stressors: psychosocial stress (isolation and restraint of ewes) and pre...

the calcium status of lactating, non-lactating, and male sheep on farm in southwestern punjab, pakistan was studied. pasture and animal were sampled at the end of the first month of summer and winter. all samplings were carried out fortnightly. a mineral supplement was available to all animals throughout the year. plasma calcium in all animals was not affected by the physiologic state and gende...

BACKGROUND Vanadium is an important environmental and industrial pollutant. It has a status of reproductive toxicant and is reported to cross placental barrier. OBJECTIVE The current study was performed to assess the therapeutic efficacy of Tiron and its combination with selenium against vanadium induced toxicity in lactating and suckling rats. MATERIALS AND METHODS Rats were exposed to van...

BACKGROUND Nutritional requirements are increased during pregnancy and lactation. The aim of this study was to compare the food intake and prevalence of inadequate nutrient intake among pregnant, lactating and reproductive-age women. METHODS Two-day dietary records of 322 pregnant and 751 lactating women were compared to those of 6837 non-pregnant and non-lactating women aged 19 to 40 years f...

We measured thyroid hormones and thyroxin-binding proteins in serum from 62 normal lactating and 52 nonlactating women at three months postpartum, and compared these values with those for 42 nonpregnant control women of similar age. Mean thyroxin concentrations in the lactating and nonlactating women were significantly (P less than 0.001) lower than that of the nonpregnant controls, but there w...

Background Information on the hemoglobin status of pregnant and lactating mothers was scarce. The objectives of this study were to determine the burden and determinants of anemia in the pregnant and lactating mother. Methods A comparative cross-sectional study was conducted. Descriptive statistics were used to identify the prevalence of anemia. Binary logistic regression and multiple linear r...

During lactation, mineral and nutrient requirements increase dramatically, particularly those for Ca and glucose. In contrast to monogastric species, in ruminants, it is rather unclear to which extend this physiological change due to increased demand for milk production is accompanied by functional adaptations of the gastrointestinal tract (GIT). Therefore, we investigated potential modulations...
