Identification of candidate genes and regulatory factors related to growth rate through hypothalamus transcriptome analyses in broiler chickens.

ABSTRACT:

Background

Intensive selection for growth rate (GR) in broiler chickens carries negative after-effects, such as aberrations in skeletal development and the immune system, heart failure, and deterioration of meat quality. In Poland, fast-growing chicken populations are highly non-uniform in term of growth rate, which is highly unprofitable for poultry producers. Therefore, the identification of genetic markers for boiler GR that could support the selection process is needed. The hypothalamus is strongly associated with growth regulation by inducing important pituitary hormones. Therefore, the present study used this tissue to pinpoint genes involved in chicken growth control.

Results

The experiment included male broilers of Ross 308 strain in two developmental stages, after 3
