The pituitary hormonal changes related to feed efficiency in pigs
In Poland, conducted for years porcine breeding works focused on improving meat content in the carcass without undertaken to accomplish the more effectiveness of fattening indicators that impact on feed efficiency. At present, feeding and feed conversion became important factors that are especially evident in the countries where the production of fattening pigs is conducted in large farms. In the present study, was attempted to indicate pituitary candidate genes depending on feed conversion ratio (FCR) in native Polish pig breed, Zlotnicka White. The whole pituitary transcriptome was sequenced using next-generation sequencing technology. The obtained results show the differences in gene expression for pathways associated with hormonal regulation and also with Notch and Wnt signaling. Moreover, it was observed that worse FCR in Zlotnicka pigs was associated with a higher fat level in a carcass and a significant higher level of prolactin expression in the pituitary.
