A large amount of research, primarily in mammals, has defined to a great extent the
pleiotropic effects of the IGF system on growth, development, and intermediary metabolism …

1. Rapidly growing (meat-type) chickens have been intensively selected for over 50 years
and grow up to four times faster than “layer” strains selected for reproductive traits. 2. 2 …

Insulin-like growth factors (IGFs) stimulate growth rate in a number of animal species and
are likely to contribute to genetic variations of growth potential. The present study was …

Molecular genetic selection on individual genes is a promising method to genetically
improve economically important traits in chickens. A resource population was developed to …

In this study we addressed the effect of various monochromatic light treatments on muscle
growth and satellite cell proliferation in broilers (Gallus domesticus). Broilers were reared …

Developmental hormonal changes in Cobb 500 chick embryos and hatched chicks were
determined by measuring plasma insulin, glucagon, insulin-like growth factor (IGF)-I, IGF-II …

Background Body weight (BW) is an economically important trait in the broiler (meat-type
chickens) industry. Under the assumption of polygenicity, a “large” number of genes with …

The insulin-like growth factor I (IGF-I) gene was screened for genetic variants associated
with trait means and trait correlations. Analysis of an unselected randomly mated White …

A novel complementary DNA (cDNA) encoding the chicken GH receptor was isolated from a
chicken liver cDNA library, using polymerase chain reaction with primers derived from highly …

Markers of alleles for three physiological candidate genes for reproductive traits, growth
hormone (GHR), gonadotropin-releasing hormone receptor (GNRHR) and neuropeptide Y …
