Association of Polymorphisms for prolactin and prolactin

Prolactin is a particularly intriguing hormone because it has such a wide range of effects stretching from osmoregulation to reproduction (reviews, Ensor 1978, de Vlaming 1979). In lactating mammals it is responsible for milk production whilst in birds its best known function is on the crop sac of...
Recent advances in understanding the hormone control of broodiness have led to the identification of two novel potential veterinary products for immunization against broodiness. The first is based on the observation that an increase in the secretion of the pituitary hormone, prolactin, causes broodiness. The prolactin gene of the domestic fowl has been cloned and used to produce

what’s a broody hen & what causes broodiness? A broody hen is one that is inspired to sit on a nest until she hatches chicks . It is an instinct influenced by hormones and lighting factors that can be triggered by seeing a collection of eggs in a nest or another broody hunkered down in a nest box. converting to pdf in rivet Read "The possible role of prolactin in laying performance and steroid hormone secretion in domestic hen ( Gallus domesticus ), General and Comparative Endocrinology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips..

  • Prolactin (PRL) is a peptide hormone synthesized and secreted by lactotroph cells in anterior pituitary of the hen. In aves, hyper secretion of PRL causes ovarian regression, ovarian dysfunction and broodiness. In addition, pituitary estrogens (E2β) play synergetic effects on both replication and synthesis of PRL in pituitary lactotrophs leading to hyperprolactinemia. The aim of this study

  • Chicken prolactin (PRL) is a physiological candidate gene for egg production. Variations of T8052C and G8113C in exon 5 of PRL gene may associate with chicken egg production. The objective of the study was to investigate the association of these two single nucleotide polymorphisms in PRL gene with
