Megjegyzések:	Nutritional limitation is a common phenomenon in nature that leads to trade-offsamong processes competing for limited resources. These trade-offs are mediatedby changes in physiological traits such as growth factors and circulating lipids.However, studies addressing the sex-specific effect of nutritional deficiency onthese physiological variables are limited in birds. We used dietary restriction tomimic the depletion of resources to various degrees and investigated sex-specificeffects on circulating levels of insulin-like growth factor 1 (IGF-1) and triglyceridesin Japanese quails (Coturnix japonica) subjected to ad libitum, 20%, 30% or 40%restriction of their daily requirement, for 2 weeks. We also explored the associa-tion of both physiological variables with body mass and egg production. While di-etary restriction showed no effects on circulating IGF-1, this hormone exhibiteda marked sexual difference, with females having 64.7% higher IGF-1 levels thanmales. Dietary restriction significantly reduced plasma triglyceride levels in bothsexes. Females showed more than six-fold higher triglyceride levels than males.Triglyceride levels were positively associated with body mass in females whileshowed not association in males. Overall, our findings revealed sex-specific expres-sion of physiological variables under dietary restriction conditions, which coincidewith body size
