Changes in behaviour and prolactin secretion in bantam hens (gallus domesticus) during extended incubation
… hen is maintained by increased concentrations of plasma prolactin and is normally terminated by the hatching of the eggs. At this time concentrations of plasma prolactin decrease. Hens sitting on infertile eggs will continue to incubate for 12 weeks or more, well beyond the normal 3-week …

The effect of photoperiod on central steroid receptor expression and plasma hormone concentration in the ring dove (Streptopelia Risoria)
… to investigate the influence of photoperiod upon plasma prolactin and luteinizing hormone (LH) concentrations, together with the expression of androgen receptor immunoreactivity (ARir) and progesterone receptor immunoreactivity (PR-ir) within the brain and anterior pituitary gland of both male and …

Effects of maternal Bromocriptine and Melatonin treatments on fetal development : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University, Palmerston North, New Zealand
… mediated by seasonal differences in circulating prolactin concentrations in the dams and/or fetuses (Jenkinson et al., 1994; McCoard et al., 1996). Plasma prolactin concentrations are likely to be very high in autumn-lambing ewes (December-mated ewes) during the early- to mid-gestation period …

Recovery from depressive illness after electroconvulsive therapy
Experiment One Plasma concentrations of oxytocin-associated neurophysin and prolactin were measured before and after the first treatment in a course of electro-convulsive therapy (ECT) given to 25 depressed patients. Plasma neurophysin concentration was measured by the radioimmunoassay (RIA) of …

The Role of Escherichia Coli Endotoxins in The Pathogenesis of Lactation Failure in The Sow
… kg sows on day 2 postpartum (PP + 2) decreased plasma prolactin (PRL) concentrations to 25-35% of pre-endotoxin concentrations within 4 hours. Piglet weight, an indirect indicator of milk production, declined significantly concomitant with the decline in PRL. Experiment II demonstrated that 8mg …

Prolactin and wool growth in the Romney ewe : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in animal science at Massey University
… effects of seasonal and experimental changes m plasma prolactin (PRL) concentration on wool growth in non-pregnant and breeding Romney ewes were assessed. Seasonal changes in plasma PRL concentration appeared to be primarily determined by photoperiod, rather than ambient temperature. The …

Neuroendocrine regulation of broodiness in the domestic hen
… Incubation behaviour is initiated by increased plasma progesterone and oestrogen from maturing ovarian follicles that induce nesting behaviour. This is subsequently transformed into incubation behaviour by increased plasma prolactin in association with decreased gonadotrophin and ovarian steroid …

Stress and Recurrent Miscarriage
… including cortisol, natural killer cells and prolactin. The first part of this thesis compared the psychological stress status in a cohort of women with unexplained RM with that of fertile health women. The results showed that women with RM had higher levels of psychological stress than …
