Influence of fasting on (A) daily seed consumption of breeding pairs of zebra finches, and on (B) body mass, (C) plasma triacylglyceride levels, (D) the proportion of very-low density lipoprotein (VLDL) particles available for use by the developing ovarian follicles as defined by the proposed selective sieving properties of the ovary, i.e. the proportion of particles that fell within the sVLDLy diameter range (25–44 nm), (E) modal VLDL particle diameter, and (F) VLDL particle diameter distribution range of laying female zebra finches.
