The somatotropic axis, consisting of growth hormone (GH), hepatic insulin‐like growth factor
I (IGF‐I), and assorted releasing factors, regulates growth and body composition …

Duck is the second-largest poultry species aside from chicken. The rate of egg production is
a major determinant of the economic income of poultry farmers. Among the reproductive …

In general, there is a relationship between growth and reproduction, and gonads are known
to be important organs for growth, but direct evidence for their role is lacking. Here, using a …

Accumulated evidence suggests that the growth hormone (GH) gene plays a physiological
role in the control of reproductive function. Here, we examined the correlation between egg …

Duck eggs are highly nutritious, and demand for consumption has markedly increased in the
growing human population, resulting in the need to increase production. Egg production is …

Preovulatory follicular development (PFD) is mainly regulated by gonadotropins (FSH, LH)
and steroids, although other intraovarian factors are also involved. We analyzed the local …

It is known that growth hormone (GH) and its receptor (GHR) are expressed in granulosa
cells (GC) and thecal cells during the follicular development in the hen ovary, which …

The aim of this study was to examine the in vivo effect of growth hormone (GH) on cell
proliferation and apoptosis and on the gene expression of selected proteins in the chicken …

Increasing evidence shows that growth hormone (GH) expression is not limited to the
pituitary, as it can be produced in many other tissues. It is known that growth hormone (GH) …

Pituitary GH is obligatory for normal growth in mammals, but the importance of pituitary GH
in avian growth is less certain. In birds, pituitary GH is biologically active and has growth …
