Dietary Zn Deficiency Inhibits Cell Proliferation via the GPR39-Mediated Suppression of the PI3K/AKT/mTOR Signaling Pathway in the Jejunum of Broilers.

ABSTRACT: A prior investigation revealed that a lack of Zinc (Zn) could hinder intestinal cell proliferation in broiler chickens; however, the mechanisms responsible for this effect remain unclear. We aimed to investigate the possible mechanisms of dietary Zn deficiency in inhibiting the jejunal cell proliferation of broilers. For this study, a total of 112 chickens (21 days old) were randomly divided into two treatments (seven replicate cages per treatment, eight chickens per replicate cage): the control group (CON) and the Zn deficiency group. The duration of feeding was 21 d. Chickens in the control group were provided with a basal diet containing an extra addition of 40 mg Zn/kg in the form of Zn sulfate, whereas chickens in the Zn deficiency group were given the basal diet with no Zn supplement
