Effects of Caponization on Expression of Gonadotropin-Releasing Hormone-I and Gonadotropin Subunits Genes in Roosters.

ABSTRACT: We evaluated the effects of caponization on mRNA levels of gonadotropin-releasing hormone-I (GnRH-I), gonadotropin subunit and other hypothalamic and hypophyseal peptide genes in male chicken. Thirty roosters (25 d) with similar weight were equally divided into the experimental (capons) and control (sham-operated males) groups randomly. Caponization was performed at 28 days of age and birds were slaughtered at 140 days of age. Caponization resulted in increasing levels of luteinizing hormone β (LHβ) and follicle-stimulating hormone β (FSHβ) mRNA in the pituitary gland and levels of LH and FSH in serum (P<0.05 or P<0.01). There were no significant differences in levels of GnRH-I, Gonadotropin releasing hormone receptor (GnRHR),
